Description

The present invention relates to a paper medium value giving system, a paper medium value guarantee server, and a paper medium value giving method.

With the development of IT technology in recent years, electronic payment services such as virtual currency and electronic money have become widespread. On the other hand, people originally trade through paper media such as banknotes and gift certificates, and the demand for transactions using such paper media still persists among people. In other words, there are a considerable number of people who feel reassured that value exchange through transactions has been carried out reliably by giving and receiving paper media, which are tangible and tangible objects of value. Further, while the paper medium is easily available and easy to handle, it is also easy to forge.

In order to enhance the security of transactions through such paper media, it is necessary to prevent forgery of the paper media and ensure the originality of the paper media. As a technique for ensuring the originality of a paper medium, Japanese Patent Application Laid-Open No. 2004-102562 (hereinafter, Patent Document 1) is available.

Need to obtain these specially processed paper media in advance. That is, in the techniques described in Patent Document 2 and Patent Document 3, it takes time and cost to process and obtain a paper medium.

For this reason, it is necessary to ensure the originality of each paper medium without any special processing on the paper medium. Patent Document 2 and Patent Document 3 use pre-processed paper, give value information (payment amount) to the paper medium without performing special processing in advance, and receive the paper medium. It is not considered that a person certifies the paper medium with high accuracy. Further, it is not an issue to certify a paper medium that is not specially processed on such a paper medium.

More specifically, the technique described in Patent Document 2 aims to "enhance the security of gift certificates and enable the distribution management thereof to be performed quickly through a communication line". It is not an object of the present invention to impart value information to a paper medium without subjecting it to special processing in advance, which is one of the objects of the present invention. In addition, the technology described in Patent Document 3 states that "a potential customer applies for the purchase of securities, purchases the securities, transfers the purchased securities to a trustee, prints out and prints out the purchased non-counterfeit hard copy securities. It is an object of the present invention to provide a securities issuing system equipped with a plurality of issuing machines installed at various locations convenient for redistribution of non-counterfeit hard copy securities to the system. It is not intended to give value information to paper media without any special processing in advance. Therefore, the inventions described in Patent Document 2 and Patent Document 3 do not guarantee the originality of each paper medium without special processing on the paper medium, which is the object of the present invention.

Also, for example, when passing the value of virtual currency, the virtual currency holder exchanges the virtual currency for real currency and hands over the exchanged real currency to the recipient, or the recipient registers a virtual currency account. I had to receive cryptocurrencies from cryptocurrency holders.

For virtual currency holders, the advantage of virtual currency is lost because it takes time and effort to exchange virtual currency for real currency. In addition, the recipient has to register a virtual currency account.

In the above example, it is desired that the virtual currency holder execute the transaction without exchanging the virtual currency for the real currency and the recipient receives the paper medium. That is, the value deliverer (the virtual currency holder in the above example) gives the value information (the virtual currency balance in the above example) to the paper medium, and the authentication requester (receipt of the above example) receives the paper medium. Person) is desired to certify the paper medium with high accuracy. As a result, it is desirable to carry out value transfer, that is, transactions smoothly and safely with anyone.

Moreover, the same problem arises not only in virtual currency but also in the delivery of all values. For example, in a local currency (regional gift certificate) that can be used in a specific region, the initial holder of the local currency (issuer of the regional gift certificate) grants the local currency to the paper medium, that is, as a gift certificate to the paper medium. It is desired that the store that gives the value of the paper medium and receives the paper medium through the customer certifies the paper medium with high accuracy.

Therefore, one aspect of the present invention is to give value information (payment amount) to a paper medium without performing special processing in advance, and to authenticate the paper medium received by the recipient with high accuracy. .. As a result, the purpose is to carry out value transfer, that is, transactions smoothly and safely between any two parties.

In order to solve the above problems, one aspect of the present invention adopts, for example, the following configuration. A system that adds value to a paper medium, that is, an authentication server, an authentication requester terminal that acquires an image feature amount of the first paper medium, the image feature amount of each of one or more paper media, and the above one or more. The management computer including a management computer that manages the paper medium information including the value information of each paper medium, and the image feature amount indicates the physical properties peculiar to the paper generated in the process of producing the paper. The paper medium information is transmitted to the authentication server, the authentication requester terminal transmits the image feature amount of the first paper medium to the authentication server, and the authentication server is the image feature amount of the first paper medium. Based on the comparison result with the image feature amount included in the paper medium information, it is determined whether or not the first paper medium is registered in the paper medium information, and based on the result of the determination. Then, when the authentication process of the first paper medium is executed and the result of the authentication process of the first paper medium is successful, the value information corresponding to the first paper medium is acquired from the paper medium information. A system that executes value assurance processing based on the acquired value information on the first paper medium.

The paper medium in the present embodiment includes, for example, a paper medium that is not printed or printed, a paper medium on which monetary information is printed, and any paper medium such as a painting or a calligraphy work. The paper medium value giving system of the present embodiment accepts the input of the image information of the paper medium and the value information of the paper medium, and gives the value to the paper medium. The image information on a paper medium is information indicating the physical properties peculiar to the paper generated in the process of producing the paper (excluding printing). That is, the image information is information that does not change due to printing or printing.

For example, when the image information of a paper medium that is not printed or printed and the transfer amount information of the virtual currency balance, which is an example of the value information, are registered in the paper medium value granting system, the transfer amount is transferred to the paper medium. Is given. As a result, the paper medium that was originally worthless becomes a paper medium that has the value of the transfer amount.

Further, for example, the image information of the paper medium which is an art piece and the originality proof information including the author name, the work name, the appraisal proof information of the work of art, etc., which is an example of the value information, are on paper. When registered in the medium value-giving system, the work of art becomes a paper medium having the value indicated by the originality proof information.

The paper medium value-imparting system executes the authentication process of the first paper medium based on the comparison result between the image information of the first paper medium, which is the object of the certification request, and the image information of the paper medium registered in advance. When the result of the authentication process is successful, the paper medium value-giving system executes the value assurance process based on the value information corresponding to the first paper medium registered in advance.

The paper medium value-adding system of the present embodiment adds value to any paper medium without any special processing by the above-mentioned processing, and certifies the paper medium to which the value of the paper medium is given with high accuracy. Can be done. In addition, transactions between the two parties, that is, value transfer can be facilitated.

Therefore, the authentication server 100 may have an interface for reading data from removable media.

The memory 102 stores a registration information check program 111, a paper medium image registration program 112, a paper medium image authentication program 113, a value guarantee program 114, and a management information operation program 115. For example, the processor 101 functions as a registration information check unit by operating according to the registration information check program 111, and functions as a paper medium image registration unit by operating according to the paper medium image registration program 112. The same applies to other programs stored in the memory 102.

The registration information check program 111 performs registration processing and check processing of the terminal information of the authentication requester terminal 200 received from the authentication requester terminal 200. The paper medium image registration program 112 performs registration processing of the paper medium image received from the management terminal 300 and the value information of the paper medium.

The paper medium image authentication program 113 executes the authentication process of the paper medium image received from the authentication requester terminal 200. The value assurance program 114 executes a value assurance process on a paper image that has been successfully certified.

The terminal information registration request program 211 transmits to the authentication server 100 a request for executing the terminal information registration process and the check process of the authentication requester terminal 200. The paper medium image capturing program 212 captures a paper medium image using the camera 206, and stores the captured paper medium image in the paper medium image storage area 215, which will be described later.

The paper medium image transmission program 213 transmits the paper medium image held by the paper medium image storage area 215 to the authentication server 100. The paper medium status confirmation program 214 outputs the authentication status of the paper medium image with reference to the paper medium image storage area 215.

The auxiliary storage device 203 includes a paper medium image storage area 215. The paper medium image storage area 215 stores the paper medium image taken by the paper medium image capturing program 212 and the authentication status of the paper medium image.

The management terminal 300 is composed of a computer having a processor (CPU) 301, a memory 302, an auxiliary storage device 303, an input / output interface 304, and a communication interface 305. The management terminal 300 is installed in, for example, a system management facility. The certification center and the system management facility may be the same facility. Further, the management terminal 300 may be, for example, a smartphone having a data communication function, a tablet terminal, or the like. In this case, for example, the delivery person owns the management terminal 300.

The description of the processor 301, the memory 302, the auxiliary storage device 303, the input / output interface 304, and the communication interface 305 is the same as the description of the processor 101, the memory 102, the auxiliary storage device 103, the input / output interface 104, and the communication interface 105, respectively. Therefore, it is omitted.

The memory 302 includes a paper medium registration request program 311, a paper medium certification registration program 312, a management information operation request program 313, and a value guarantee program 314. The paper medium registration request program 311 requests the authentication server 100 to register the paper medium image and the value information of the paper medium. The paper medium authentication registration program 312 executes the authentication process of the paper medium image received from the authentication server 100 or the authentication requester terminal 200.

The auxiliary storage device 303 includes an authentication result storage area 315. The authentication result storage area 315 stores the paper medium image and the authentication result of the paper medium image.

Each of the devices included in the paper medium value-imparting system of the present embodiment is a computer system composed of physically one computer or a plurality of computers logically or physically configured, and is the same. It may run on a separate thread on a computer, or it may run on a virtual computer built on multiple physical computer resources.

FIG. 2 shows an example of an outline of the entire process executed in the paper medium value-adding system of this embodiment. First, the management terminal 300 receives the input of the image information and the value information of the paper medium from the delivery person of the paper medium, and transmits the input information to the authentication server 100. The authentication server 100 holds the received image information of the paper medium and the value information in association with each other. This gives value to the paper medium.

For example, when the virtual currency balance is given to a paper medium, the virtual currency balance to be given is an example of the value information of the paper medium. Further, for example, when the originality proof information as a work of art is given to a paper medium, the originality proof information is an example of the value information of the paper medium. Further, for example, when an appraisal amount as a work of art is given to a paper medium, the appraisal amount is an example of value information of the paper medium.

Further, a system administrator other than the delivery person may input the image information and the value information of the paper medium into the management terminal 300. In this case, for example, after the image information and the value information of the paper medium are registered in the authentication server 100, the paper medium is handed over from the system administrator to the delivery person.

Subsequently, a paper medium is delivered from the delivery person to the certification requester in order to execute the transaction. The authentication requester authenticates the received paper medium using the authentication requester terminal 200. The authentication requester terminal 200 receives input of image information on a paper medium from the authentication requester, and transmits the input information to the authentication server 100.

The authentication server 100 searches for an image that matches the received image information from the image information held by the authentication server 100. The authentication server 100 acquires value information corresponding to the matched image information, and executes a process of guaranteeing the value indicated by the acquired value information on a paper medium.

Specifically, when the virtual currency balance is given to the paper medium, the process of transmitting the key for withdrawing the virtual currency balance from the authentication server 100 to the authentication requester terminal 200 is the value guarantee process for the paper medium. This is just one example. Further, when the paper medium is a work of art and the originality proof information is given to the paper medium, the process of creating the originality proof data of the work of art by the authentication server 100 is an example of the value guarantee process for the paper medium. ..

In addition, one or more transaction intermediaries may intervene between the authentication requester and the recipient. Each transaction intermediary requests the authentication server 100 for paper-based authentication using the authentication requester terminal 200 possessed by each transaction intermediary. Each transaction intermediary hands over the paper to the next recipient if the authentication is successful. The authentication server 100 performs only the paper-based authentication process and does not execute the value guarantee process in response to the authentication request from the transaction intermediary.

FIG. 3 is an example of the authentication requester table 120. The authentication requester table 120 includes, for example, an authentication requester ID column 121 for storing authentication requester identification information and an update number column 122 for storing the update count of the authentication requester ID.

FIG. 4 is an example of the authentication requester history table 130. The authentication requester history table 130 may include, for example, an authentication requester ID column 131, an update number column 132, a password column 133, a name column 134, an address column 135, a representative name column 136, a transfer account column 137, and a contact column 138. And the registration date and time column 139 is included. The information stored in the authentication requester history table 130 is, for example, information transmitted from the authentication requester terminal 200.

The authentication requester ID column 131 stores the identification information of the authentication requester. The update number field 132 stores the identification information of the executed update process of the corresponding authentication requester ID. The password field 133 stores the login password for the authentication server 100 of the authentication requester terminal 200. The name field 134 stores the name of the authentication requester. The address field 135 stores the address of the authentication requester.

The representative name column 136 stores the representative name of the organization to which the certification requester belongs. The transfer account column 137 stores transfer account information such as the bank code, deposit type code, and account number of the transfer account of the authentication requester. The contact field 138 stores contact information such as the telephone number and e-mail address of the authentication requester. The registration date / time field 139 stores the date and time when the corresponding authentication requester ID is registered.

FIG. 5 is an example of the paper medium table 140. The paper medium table 140 is, for example, a paper medium ID column 141, an image information column 142, a value information column 143, a value issuer ID column 144, a certification requester ID column 145, a value guarantee status column 146, a value guarantee number column 147, and the like. It includes a collation count column 148, a validity period column 149, a usage restriction code column 161; an authentication requester information column 162, and a delivery person information column 163.

The paper medium ID column 141 stores the identification information of the paper medium. The image information column 142 stores the paper medium image and the feature amount of the paper medium image. The feature amount of the paper medium image in the present embodiment includes information according to the physical properties peculiar to the paper generated in the process of producing the paper (excluding printing). Even when the print content of one paper medium is copied to another paper medium, the feature amounts of both paper media are different. Therefore, by executing the authentication using the feature amount, the paper medium value-adding system can accurately execute the authentication process of any paper medium.

For example, the feature amount showing the paper fiber pattern constituting the paper medium is an example of the feature amount, and shows the physical properties generated in the process of producing paper. For example, even if printing or stains occur on the paper medium, the paper fiber pattern does not change, and the authentication process of the paper medium can be accurately executed. Even if a special fiber pattern or the like is not embedded in the paper, there is a random pattern in which the plant fibers are irregularly overlapped on the paper. By using the random pattern as the paper fiber pattern, the authentication process can be accurately executed even on a paper medium that has not been specially processed in advance.

The value information column 143 stores the value information of the paper medium. When the virtual currency balance is given to the paper medium, the value information field 143 stores the given virtual currency balance. Further, when the paper medium is a work of art and the originality proof information is given to the paper medium, the value information column 143 stores, for example, the originality proof information.

The value issuer ID column 144 stores information that identifies the value issuer who has transmitted the paper medium image and the value information registration request using the management terminal 300. In the example of FIG. 2, the value issuer is the same as the deliverer. The authentication requester ID 145 stores the identification information of the authentication requester ID that is permitted to authenticate the paper medium. The value guarantee status column 146 stores information indicating whether or not the value guarantee process has been executed for the corresponding paper medium. The value guarantee number field 147 stores information identifying the performed value guarantee processing for the corresponding paper medium.

The collation count column 148 stores the number of times the authentication process is executed on the corresponding paper medium. The validity period column 149 stores the validity period of the corresponding paper medium. The valid period indicated by the valid period column 149 is designated by at least one of the start period and the end period. If the validity period is specified by either the beginning or the end, it indicates that there are no restrictions on the other. The usage restriction code field 161 stores the usage restriction code of the corresponding paper medium. The usage restriction code includes a code for denying the authentication of the corresponding paper medium and a code for sending a caution message about the authentication of the corresponding paper medium to the management terminal 300.

The authentication requester information field 162 stores information that identifies the authentication requester, such as biometric information (palm vein, fingerprint, pupil, etc.) of the authentication requester. The delivery person information column 163 stores information that identifies the delivery person, such as biometric information of the delivery person and the imprint of the seal of the delivery person. The authentication requester ID, the authentication requester information, and the delivery person information are examples of operator information of the operator who operates the paper medium value-imparting system.

The paper medium table 140 may further include, for example, an authentication valid place column. The authentication valid place column stores, for example, information indicating a range of places where authentication of the corresponding paper medium is valid. That is, when the position of the authentication requester terminal 200 at the time of transmitting the authentication request of the paper medium is not included in the range of the place indicated by the authentication valid place column corresponding to the paper medium, the authentication server 100 is concerned. The authentication result for the authentication request is rejected.

FIG. 6 is an example of the paper medium collation history table 150. The paper medium collation history table 150 is, for example, a paper medium ID column 151, a collation number column 152, an authentication requester ID column 153, an authentication requester terminal ID column 154, a shooting date and time column 155, a paper medium image column 156, and a reason for denial. Includes column 157.

The paper medium ID column 151 stores the identification information of the paper medium. The collation number field 152 stores the identification information of the authentication process of the paper medium image. The authentication requester ID field 153 stores the identification information of the authentication requester who requested the authentication process. The authentication requester terminal ID field 154 stores the identification information of the authentication requester terminal 200 that has requested the authentication process. The shooting date / time column 155 stores the shooting date / time of the paper medium image. The paper medium image field 156 stores the paper medium image subject to the authentication process. The denial reason column 157 stores the denial reason when the result in the authentication process is denial.

FIG. 7 shows an example of a process in which the terminal information of the authentication requester terminal 200 is newly registered in the authentication server 100. The terminal information registration request program 211 starts the application according to the input from the authentication requester, and outputs a start screen for new terminal information registration (S701). The application executed by the authentication requester terminal 200 of the present embodiment may be, for example, a native application or a browser-based Web application.

The terminal information registration request program 211 outputs a new registration screen according to an instruction from the authentication requester (S702). An example of the new registration screen will be described later with reference to FIG. 18B. The authentication requester inputs the authentication requester ID and password according to the instructions on the new registration screen. The terminal information registration request program 211 transmits a terminal information registration request including an authentication requester ID and a password input by the authentication requester to the authentication server 100 (S703).

The registration information check program 111 executes the terminal information registration process (S704). Specifically, the following processing is executed. The registration information check program 111 stores the authentication requester ID included in the received terminal information registration request in the authentication requester ID column 121 and the authentication requester ID column 131, and passwords the password included in the received terminal information registration request. It is stored in the column 133, and the current date and time is stored in the registration date and time column 139. Further, the registration information check program 111 issues an update number, stores the issued update number in the update number column 132, and increments the value in the update count column 122.

Further, in step S703, the terminal information registration request program 211 further receives input of information such as the name, address, representative name, transfer account information, contact information, etc. of the authentication requester from the authentication requester, and the information is received. May be sent to the authentication server 100. At this time, in step S704, the registration information check program 111 stores the received information in the corresponding cell of the authentication requester history table 130.

The registration information check program 111 transmits a terminal information registration response indicating the registration result in step S704 to the authentication requester terminal 200 (S705). The terminal information registration request program 211 outputs a menu screen (S706). An example of the menu screen will be described later with reference to FIG. 18B. However, if the registration result indicated by the received terminal information registration response is an error, the terminal information registration request program 211 does not output the menu screen, and for example, the content indicating the error is input / output interface (display screen). Output to 204, and then transition to step S702.

FIG. 8 shows an example of the terminal information check process of the authentication requester terminal 200 by the authentication server 100. The terminal information registration request program 211 starts the application according to the input from the authentication requester and outputs the start screen (S801).

The authentication requester inputs the authentication requester ID and password according to the instructions on the startup screen. The terminal information registration request program 211 transmits a terminal information check request including an authentication requester ID and a password input by the authentication requester to the authentication server 100 (S802). The registration information check program 111 uses the authentication requester ID and password included in the received terminal information registration request as the authentication requester ID stored in the authentication requester ID field 131 and the password stored in the password field 133, respectively. By comparison, the registration information check process is performed (S803).

The registration information check program 111 transmits a terminal information check response indicating the processing result of the terminal information check process in step S803 to the authentication requester terminal 200 (S804). The terminal information registration request program 211 outputs the menu screen to the input / output interface 204 (S805). However, if the processing result indicated by the received terminal information check response is an error, the terminal information registration request program 211 does not output the menu screen, and the content indicating the error is displayed on the input / output interface 204 (display screen). Output.

FIG. 9 shows an example of a process in which the authentication server 100 registers an image and a value on a paper medium. The paper medium registration request program 311 accepts input of one or more paper medium images from the delivery person (S901). Each input paper medium image is a part or all of the paper medium image. The paper medium registration request program 311 repeats the following steps S902 to S907 for each of the input paper media images.

The paper medium registration request program 311 accepts the input of the value of the paper medium from the delivery person (S902). The paper medium registration request program 311 includes the paper medium image, the value of the paper medium image input in S902, and the value issuer ID which is the ID of the delivery person who made the input in S902. The request is transmitted to the authentication server 100 (S903).

In step S902, the paper medium registration request program 311 further accepts the input of the authentication requester ID, the validity period, the authentication requester information, the delivery person information, the authentication valid time, the authentication valid place, and the like from the delivery person. May be good. At this time, the paper medium registration request program 311 further includes the input information in the paper medium registration request in step S903.

Subsequently, the paper medium image registration program 112 extracts the feature amount of the image from the paper medium image included in the received paper medium registration request (S904). The feature amount extraction process may be performed by the paper medium registration request program 311 in step S901, and the feature amount extracted by the paper medium registration request program 311 in step S903 may be included in the paper medium registration request. In this case, step S904 is omitted.

The paper medium image registration program 112 issues a paper medium ID, and stores the issued paper medium ID, the extracted feature amount, and the information included in the paper medium registration request in the paper medium table 140 in association with each other (S905).

For example, when the information of the paper medium having the same or similar feature amount as the extracted feature amount is already stored in the paper medium table 140, the paper medium image registration program 112 does not execute the registration process in step S905. .. Specifically, for example, when the norm of the difference between the two feature amounts is equal to or less than a predetermined threshold value, the paper medium image registration program 112 determines that the two feature amounts are the same or similar.

The paper medium image registration program 112 transmits a paper medium registration response indicating the registration result in step S905 to the management terminal 300 (S906). The paper medium registration request program 311 outputs the registration result indicated by the received paper medium registration response to the input / output interface 304 (S907).

FIG. 10 shows an example of the authentication process by the paper medium value-adding system. The paper medium image shooting program 212 uses the camera 206 to shoot one or more images of the paper medium subject to the certification request (S1001). The paper medium image capturing program 212 stores each paper medium image in the paper medium image storage area 215 in association with the authentication status. The authentication status of each paper medium image at the time of step S1001 is "waiting for transmission".

Hereinafter, the following processes of steps S1002 to S1015 are executed for each paper medium image captured in step S1001. Further, the processes of steps S1002 to S1015 may be collectively executed for the plurality of paper media images captured in step S1001.

The paper medium image transmission program 213 transmits a paper medium image check request including the paper medium image to the authentication server 100 (S1002). The paper medium image transmission program 213 may include, for example, the position information of the authentication requester terminal 200 at the time of transmitting the paper medium check request in the paper medium image check request. The paper medium image authentication program 113 stores the paper medium image included in the received paper medium image check request in the paper medium image column 156 (S1003). The paper medium image authentication program 113 transmits a paper medium image check response indicating that the paper medium image has been received to the authentication requester terminal 200 (S1004).

The paper medium image transmission program 213 receives the paper medium image check response and changes the authentication status of the paper medium image in the paper medium image storage area 215 to “transmitted” (S1005). For example, when a predetermined time has elapsed since the paper medium image check request including the paper medium image was transmitted in step S1002, the paper medium image transmission program 213 transfers the paper medium image in the paper medium image storage area 215. Change the authentication status to "Send error".

The paper medium image authentication program 113 extracts a feature amount from the received paper medium image, and uses the extracted feature amount and the feature amount of each paper medium image registered in the paper medium table 140 to use the paper medium. Image authentication processing is performed (S1006). That is, the paper medium image authentication program 113 searches the paper medium table 140 for a paper medium image that matches the received paper medium image, and identifies the paper medium ID corresponding to the received paper medium image. The details of the authentication process in step S1006 will be described later with reference to FIG.

In step S1002, the paper medium image transmission program 213 may extract the feature amount of the paper medium image included in the paper medium image check request, and include the extracted feature amount in the paper medium image check request.

The paper medium image authentication program 113 transmits to the management terminal 300 a paper medium authentication notification including the received paper medium image, the specified paper medium ID, and the authentication result (S1007). The authentication result in step S1007 includes, for example, information indicating whether or not the authentication is successful, and if the authentication is successful, the authentication result in the paper medium table 140 certified to be the same as the paper medium image. Further includes image information. Further, when the authentication fails (rejected), the processes of steps S1007 to S1009 and steps S1011 to S1012 may be omitted.

The paper medium authentication registration program 312 stores the received paper medium image in the authentication result storage area 315, and further executes the paper medium image authentication process according to the input from the delivery person, for example (S1008). The details of the authentication process in step S1008 will be described later with reference to FIG. The paper medium authentication registration program 312 stores the authentication result in step S1008 in the authentication result storage area 315 in association with the received image.

The paper medium authentication registration program 312 transmits a paper medium authentication result registration request including the authentication result in step S1008 to the authentication server 100 (S1009). The paper medium image authentication program 113 registers the paper medium authentication result (S1010). Specifically, the paper medium image authentication program 113 updates the paper medium table 140 and the paper medium collation history table 150 based on the authentication result indicated by the paper medium authentication result registration request.

The paper medium image authentication program 113 transmits a paper medium authentication result registration response indicating that the registration of the authentication result is completed to the management terminal 300 (S1011). The paper medium authentication registration program 312 outputs the authentication result in step S1008 to the input / output interface 304 (S1012).

The value guarantee program 114 refers to the paper medium table 140 and executes the value guarantee process for the paper medium only when the authentication result is successful (S1013). Instead of step S1013, after step S1008, the value guarantee program 114 executes the value guarantee process. The value guarantee program 314 may execute the value guarantee process, include the process result in the paper medium authentication result registration request in step S1009, and transmit the process result to the authentication server 100.

Subsequently, the paper medium image authentication program 113 transmits a paper medium authentication result notification including the authentication result registered in step S1010 to the authentication requester terminal 200 (S1014). The paper medium image transmission program 213 updates the authentication status of the paper medium transmitted in S1002 in the paper medium image storage area 215 according to the authentication result indicated by the paper medium authentication result notification (S1015). Specifically, for example, the paper medium image transmission program 213 changes the authentication status of the paper medium image to "certified (OK)" when the authentication result is successful, and the authentication result is unsuccessful. In this case, the authentication status of the paper image is changed to "certified (NG)".

The authentication process in the management terminal 300, that is, the processes of steps S1007 to S1009, steps S1011, and step S1012 may be omitted. At this time, the paper medium image authentication program 113 registers the authentication result of the authentication process of step S1006 in step S1010.

Further, for example, the authentication process in the management terminal 300 may be executed by batch processing at regular time intervals or every time the authentication process for a certain number of paper media images is executed in step S1006. At this time, in step S1010, the paper medium image authentication program 113 registers the authentication result by the authentication process of step S1006 without waiting for the receipt of the paper medium authentication result registration request of step S1009.

Further, the authentication process by the authentication server 100 may be executed after the authentication process by the management terminal 300. Hereinafter, the differences from the above-mentioned processing in this case will be described. The paper medium image authentication program 113 does not execute the process of step S1006 after step S1004, and transmits a paper medium authentication notification including the image of the paper medium to the management terminal 300 in step S1007.

If the authentication result indicated by the paper medium authentication result registration response received in step S1009 is successful, the paper medium image authentication program 113 executes the paper medium authentication process of step S1006 and registers the process result in step S1010. If the paper medium image authentication program 113 does not execute the process of step S1006 when the authentication result indicated by the paper medium authentication result registration response received in step S1009 fails, the paper medium image authentication program 113 does not execute the process of step S1006 and registers the authentication result indicating that the authentication failed in step S1010. However, the process of step S1011 is not executed.

FIG. 11 shows an example of the system management process by the management terminal 300. Hereinafter, an example in which the management terminal 300 accepts an input from the delivery person will be described. The management information operation request program 313 receives a login screen display command for management from the delivery person (S1101), and sends a login screen acquisition request to the authentication server 100 (S1102).

The management information operation request program 313 transmits a login request including the login ID and password entered in S1105 to the authentication server 100 (S1106).

The management information operation program 115 determines whether or not the received login ID and password are valid, and transmits a login response indicating the login result to the management terminal 300 (S1107). When the management information operation program 115 determines that the received login ID and password are valid, the management information operation program 115 includes information necessary for displaying the management screen in the login response. Further, when the management information operation program 115 determines that the received login ID and password are not valid, the management information operation request program 313 includes the information necessary for displaying the error screen in the login response, and the management information operation request program 313 includes the information included in the login response. Output an error screen using.

The following processes after step S1108 are processes performed only when login is successful. The management information operation request program 313 displays the management screen according to the information included in the login response (S1108). For example, the management screen includes an area for receiving input for operations such as registration, reference, and change of management information including information of each table held by the auxiliary storage device 103. In addition, the management screen includes an area for accepting input of a logout request.

Further, the management screen further includes an area for receiving an input of an execution instruction of the paper medium image display process and an area for receiving an input of an execution instruction of the value assurance process, and these areas are described in FIG. 16 below. Used in processing.

The management information operation request program 313 accepts input of a management information registration, reference, or change operation from the delivery person (S1109). The management information operation request program 313 transmits a management information operation request including the operation content to the authentication server 100 (S1110).

The details of the paper medium shooting confirmation screen will be described later with reference to FIG. 18C. When the authentication requester operates the "Save" button on the paper medium shooting confirmation screen (S1302: save), the paper medium image shooting program 212 sets the authentication status of the shot paper medium image as "waiting for transmission" and includes the shooting date and time. The paper medium image and the authentication status are stored in the paper medium image storage area 215.

FIG. 14 shows an example of a paper medium image transmission process (S1207) by the authentication requester terminal 200. The process of FIG. 14 corresponds to the process of step S1005 in FIG. The paper medium image transmission program 213 outputs a paper medium image transmission confirmation screen (S1401). Details of the paper image transmission confirmation screen will be described later with reference to FIG. 18D.

The paper medium image transmission program 213 receives an instruction from the authentication requester via the paper medium transmission confirmation screen (S1402). When the authentication requester operates the "Cancel" button on the paper medium image transmission confirmation screen or does not select an image (S1402: NO), the paper medium image transmission program 213 ends the transmission process.

When the authentication requester selects one or more images on the paper medium image transmission confirmation screen (S1402: YES), the paper medium image transmission program 213 outputs the paper medium image transmission screen (S1403). Details of the paper image transmission screen will be described later with reference to FIG. 18B.

Subsequently, the paper medium image transmission program 213 executes the processes of steps S1405 and S1406 for each untransmitted image selected in step S1402 (S1404), and transitions to step S1401.

The paper medium image transmission program 213 determines whether or not the authentication requester has operated the "Cancel" button on the paper medium image transmission screen (S1405). When the cancel button is operated (S1405: YES), the paper medium image transmission program 213 cancels the image transmission process being executed and the transmission process of all untransmitted images, and transitions to step S1401. When the cancel button is not selected (S1405: NO), the paper medium image transmission program 213 transmits the untransmitted image to the authentication server 100 (S1406).

FIG. 15 shows an example of a paper medium image authentication process by the authentication server 100. The process of FIG. 15 corresponds to the process of the authentication server 100 after step S1003 in FIG. The paper medium image authentication program 113 performs a check process of the paper medium image received from the authentication requester terminal 200 (S1501).

In step S1501, for example, the paper medium image authentication program 113 issues a collation number. The paper medium image authentication program 113 authenticates the issued collation number (hereinafter referred to as the first collation number) in the collation number field 152 and the authentication requester ID logged in to the authentication requester terminal 200 that transmitted the paper medium image. In the requester ID column 153, the ID of the authentication requester terminal 200 that transmitted the paper medium image is in the authentication requester terminal ID column 154, and the shooting date and time included in the received paper medium image is in the shooting date and time column 155. The medium image is stored in the memory 202 or the auxiliary storage device 203, respectively. After that, the paper medium image authentication program 113 notifies the authentication requester terminal that the paper medium image has been received.

Subsequently, the paper medium image authentication program 113 extracts the feature amount from the received paper medium image, and the extracted feature amount and the feature amount of each paper medium image stored in the image information column 142 of the paper medium table 140. , And authenticate the received paper medium image (S1502).

An example of the paper medium image authentication process in step S1502 will be described. The paper medium image authentication program 113 calculates, for example, the norm of the difference between the feature amount of the received paper medium image and the feature amount stored in the paper medium table 140. The paper medium image authentication program 113 calculates the value obtained by substituting each of the calculated norms into a predetermined decreasing function as the image similarity. That is, the smaller the norm of the difference in features, the more similar the two images.

For example, when the paper medium image authentication program 113 receives the paper medium ID together with the paper medium image, for example, the paper medium table 140 is searched and the paper having the same paper medium ID as the received paper medium ID is obtained. The degree of similarity with the received paper medium image may be calculated only for the medium image. When information indicating a paper medium ID such as a character or a two-dimensional code is printed or printed on the paper medium, the paper medium image authentication program 113 performs character recognition, decoding of the two-dimensional code, or the like to perform the paper medium. The paper medium ID may be extracted from the image.

If the same paper medium ID as the received paper medium ID does not exist in the paper medium table 140, the paper medium image authentication program 113 may perform the process of step S1502 again assuming that the paper medium ID has not been received. Then, the reason for denial that the same paper medium ID did not exist may be recorded in the denial reason column 157 corresponding to the first collation number, and the process may proceed to step S1508. When the same paper medium ID as the received paper medium ID exists in the paper medium table 140, the paper medium image authentication program 113 increments the value of the collation count column 148 corresponding to the paper medium ID, and the first collation number. The paper medium ID is stored in the paper medium ID column 151 corresponding to the above.

Subsequently, the paper medium image authentication program 113 determines whether or not each of the calculated similarities is equal to or higher than a predetermined authentication threshold value (S1503). When all the calculated similarities are less than the predetermined authentication threshold value (S1503: NO), the reason for denial indicating that the paper medium image similar to the received paper medium image is not registered in the paper medium table 140 is given. 1 It is stored in the denial reason column 157 corresponding to the collation number (S1504), and the process proceeds to step S1508.

When there is a similarity equal to or greater than a predetermined authentication threshold (S1503: YES), the paper medium image authentication program 113 selects the maximum similarity. The paper medium image authentication program 113 corresponds to the paper medium image corresponding to the selected similarity in the paper medium table 140 (hereinafter, the paper medium is referred to as a first paper medium, and the image of the first paper medium is referred to as a first paper medium image). A paper medium authentication notification including the paper medium ID, the received paper medium image, and the authentication result indicating that the authentication was successful is transmitted to the management terminal 300. When a value indicating a caution message is stored in the usage restriction code field 161 corresponding to the paper medium ID, the paper medium image authentication program 113 includes the caution message indicated by the value in the paper medium authentication notification. The paper medium image authentication program 113 receives the authentication result by the management terminal 300 from the management terminal 300, and determines whether or not the authentication result is successful (S1505).

When there is a similarity equal to or higher than a predetermined authentication threshold (S1503: YES), the paper medium image authentication program 113 increments the value of the collation count column 148 corresponding to the first paper medium image, and the first paper. The value of the paper medium ID corresponding to the medium image is acquired from the paper medium ID column 141, and the acquired value of the paper medium ID is stored in the paper medium ID column 151 corresponding to the first collation number.

In step S1503, the paper medium image authentication program 113 has the authentication requester ID column 145, the value guarantee number column 147, the number of verifications column 148, the validity period column 149, and the usage restriction code column 161 of the first paper medium image. Further, the authentication process using at least one information in the authentication requester information column 162 and the delivery person information column 163 may be performed. The paper medium image authentication program 113 transmits the paper medium authentication notification to the management terminal 300 only when the authentication process is successful.

The paper medium image authentication program 113 may execute the authentication process using the information described below in addition to the authentication process using the similarity of the paper medium images in steps S1502 to S1503. When at least one reason for denial is recorded in the authentication process, the paper medium image authentication program 113 does not send the paper medium authentication notification to the management terminal 300, and transitions to step S1508. The paper medium image authentication program 113 can secure a higher security level by further executing the authentication process. Hereinafter, the authentication process will be described.

When the value of the authentication requester ID column 145 of the first paper medium image is not a null value, the paper medium image authentication program 113 may use, for example, the authentication requester ID of the authentication requester who transmitted the paper medium image and the authentication requester. Compare with the authentication requester ID stored in the ID field 145. When the authentication requester IDs do not match in the comparison, the paper image authentication program 113 stores the reason for denial indicating that the authentication requesters do not match in the denial reason column 157 corresponding to the first collation number.

When the number of collations indicated by the collation count column 148 of the first paper medium image is equal to or greater than a predetermined threshold value, the paper medium image authentication program 113 performs, for example, collations exceeding the allowable number of times for the first paper medium. The reason for denial indicating that the item has been rejected is stored in the reason for denial column 157 corresponding to the first collation number. The threshold value may be different for each paper medium, and when the threshold value is different for each paper medium, for example, each threshold value is stored in the paper medium table 140 in association with the paper medium ID.

If the value in the value guarantee number column 147 of the first paper medium image is not a null value, the paper medium image authentication program 113 corresponds to the first collation number as a reason for denial indicating that the value has already been guaranteed for the paper medium. It is stored in the denial reason column 157.

When the value in the validity period column 149 of the first paper medium image is not a null value, the paper medium image authentication program 113 compares, for example, the current date and time with the date and time indicated by the validity period column 149 of the first paper medium image. Determine if the current date and time is within the valid period. When the current date and time is not within the valid period, the paper medium image authentication program 113 stores the denial reason indicating that the authentication time is not within the valid period in the denial reason column 157 corresponding to the first collation number.

When a value indicating a reason for denial is stored in the usage restriction code column 161, the paper medium image authentication program 113 stores the reason for denial indicated by the value in the denial reason column 157 corresponding to the first collation number column.

When the value in the authentication requester information column 162 is not a null value, for example, the paper medium image authentication program 113 transmits an authentication requester information transmission request to the authentication requester terminal 200. When the authentication requester information is the palm vein, the paper medium image capturing program 212 captures an image of the authentication requester's palm vein using the camera 206 according to the instruction from the authentication requester. The paper medium image transmission program 213 transmits the captured image to the authentication server 100.

The paper medium image authentication program 113 compares the received image of the palm vein with the image of the palm vein stored in the authentication requester information field 162. When the paper medium image authentication program 113 determines that the images of the palm veins do not match in the comparison, the denial reason indicating that the authentication requester information does not match is stored in the denial reason column 157 corresponding to the first collation number. do.

When the authentication requester information is printed on a paper medium, for example, a stamp stamped on a paper medium, the paper medium image authentication program 113 does not transmit the authentication requester information transmission request. The authentication requester information may be extracted from the paper medium.

The process when the delivery person information column 163 is not a null value is the same as the process when the value of the authentication requester information column 162 is not a null value.

The position of the authentication requester terminal 200 at the time when the paper medium table 140 includes the authentication valid place column and the paper medium image transmission program 213 transmits the paper medium image check request for the first paper medium is the authentication valid place column. If it is not included in the range of the indicated location, for example, the paper image authentication program 113 stores the denial reason indicating that the authentication request was not executed at the authentication valid location in the denial reason column 157 corresponding to the first collation number. do.

The paper medium image authentication program 113 may change the authentication process to be executed according to the value information corresponding to the first paper medium. For example, when the first paper medium is a gift certificate, the paper medium image authentication program 113 may execute more authentication processes as the value information (gift certificate amount) of the first paper medium is higher. Specifically, for example, when the amount of money of the first paper medium is 1000 yen or less, the paper medium image authentication program 113 executes the authentication process based only on the similarity of the paper medium images. For example, when the amount of money of the first paper medium is more than 1000 yen and 10,000 yen or less, the paper medium image authentication program 113 depends on the paper medium image check request reception time in addition to the authentication process based on the similarity of the paper medium images. Execute the authentication process. For example, when the amount of money of the first paper medium is more than 10,000 yen, the paper medium image authentication program 113 includes the authentication process based on the similarity of the paper medium images and the authentication process based on the time when the paper medium image check request is received, as well as the paper. The authentication process is executed based on the position information of the authentication requester terminal 200 at the time when the media image check request is transmitted.

Return to the explanation of the flowchart. In step S1505, when the authentication result from the management terminal 300 is unsuccessful (S1505: NO), the paper medium image authentication program 113 sets the reason for denial indicating that the authentication result in the management terminal 300 is unsuccessful. 1 Store in the denial reason column 157 corresponding to the collation number (S1506). When the paper medium image authentication program 113 receives a specific reason for denial from the management terminal 300, the received denial reason may be stored in the denial reason column 157 corresponding to the first collation number. ..

When the authentication result from the management terminal 300 is successful (S1505: YES), the value guarantee program 114 acquires the value information corresponding to the first paper medium image from the value information column 143 and executes the value guarantee process. (S1507). In step S1508, the value guarantee program 114 issues, for example, a value guarantee number, stores the issued value guarantee number in the value guarantee number column 147 corresponding to the first paper medium image, and corresponds to the first paper medium image. Change the value in the value guarantee status column 146 to "value guaranteed". The value guarantee process in step S1507 may be executed by the management terminal 300.

The paper medium image authentication program 113 transmits a paper medium authentication result notification including the authentication result to the authentication requester terminal 200 to the authentication requester terminal 200 (S1508). If the paper medium image authentication program 113 rejects the authentication, the reason for the denial may be further included in the paper medium authentication result notification.

FIG. 16 shows an example of the paper medium authentication process by the management terminal 300. Hereinafter, an example in which the delivery person operates the management terminal 300 will be described. The process of FIG. 16 corresponds to the process of steps S1008, S1009, S1011 and S1012 in FIG. The management information operation request program 313 outputs a login screen (S1601). For example, the management information operation request program 313 accepts the input of the login ID and the password from the delivery person, and determines whether or not the combination of the input login ID and the password is valid (S1602).

If the combination of the entered login ID and password is not valid (S1602: login failure), the process returns to step S1601. When the combination of the entered login ID and password is valid (S1602: login success), the management information operation request program 313 outputs the management screen (S1603).

When the management information operation request program 313 receives the logout request from the delivery person (S1603: logout), the management information operation request program 313 executes the logout process, outputs the logout screen (S1604), and ends the authentication process. Since the processing of steps S1601 to S1604 is the same as the processing of steps S1101 to S1108 and S1113 to S1116 of FIG. 11, details are omitted.

When the delivery person instructs the execution of the paper medium image display process (S1603: image display), the paper medium authentication registration program 312 outputs the paper medium image display screen (S1605). The paper medium image display screen is, for example, an area for displaying a paper medium image stored in the authentication result storage area 315, an area for displaying the authentication result by the management terminal 300 for each paper medium image, and authentication by the management terminal 300. It includes an area for inputting the authentication result of each paper medium image for which processing has not been executed, an area for displaying a caution message indicated by a usage restriction code, and a cancel button.

When the cancel button is selected by the delivery person (S1607: cancel), the process proceeds to step S1603. When the authentication result of one or more paper media images is input by the delivery person (S1607: authentication result), the paper media authentication registration program 312 sends each of the input authentication results to the one or more of the authentication result storage area 315. It is stored in association with the paper medium image (S1608), and the process proceeds to step S1603.

In step S1607 described above, the authentication result visually by the delivery person is input by manual processing, but it may be executed by automatic processing. For example, when the delivery person's seal is stamped on the paper medium in advance and the correspondence information between the paper medium and the imprint is stored in the auxiliary storage device 303, the paper medium certification registration program 312 extracts the imprint from the paper medium image. , The authentication process may be performed by determining whether or not the same imprint as the extracted imprint exists in the corresponding information. In addition to the authentication process by the authentication server 100, the management terminal 300 performs another authentication process, so that the security level of authentication is improved.

When the delivery person instructs the execution of the value guarantee processing in step S1603 (S1603: value guarantee), the value guarantee program 314 executes the value guarantee processing (S1606), and the transition to step S1603.

Hereinafter, an example of the processing in step S1606 will be described. The value guarantee program 314 acquires, for example, a paper medium image with a successful authentication result from the authentication result storage area 315 and displays it. When one or more paper media images are selected by the delivery person from the displayed paper media images, the value assurance program 314 issues a value information transmission request including the paper media ID of the one or more paper media images to the authentication server 100. Send to.

The value guarantee program 314 receives the value information contained in the paper medium table 140 of each of the one or more paper media images from the authentication server 100, and executes the value guarantee processing for each of the one or more paper media images. The management terminal 300 may hold information indicating a combination of the paper medium ID and the value information. In this case, the value guarantee program 314 does not transmit the value information transmission request and is in the management terminal 300. Value assurance processing may be executed using the information.

As described above, in this embodiment, the delivery person inputs the image information of the paper medium and the value information of the paper medium into the management terminal 300, and the authentication server 100 is included in the image information input to the management terminal. The image feature amount and the value information are registered in advance. The authentication server 100 compares the feature amount shown by the paper medium image received from the authentication requester terminal 200 with the feature amount registered in advance, and executes the authentication process based on the comparison result. If the authentication process is successful, the authentication server 100 executes a value guarantee process using the corresponding value information registered in advance.

As a result, the paper medium value-adding system of the present embodiment can add value to any paper medium without performing special processing, and can authenticate the paper medium with high accuracy. For example, in particular, when the management terminal 300 is a mobile terminal such as a smartphone owned by the delivery person, the delivery person can authenticate all paper media on the spot with high accuracy without any special processing. It can be transformed into a possible value medium. Further, by using the paper medium value-adding system of this embodiment, the transaction between the two is established by the movement of the paper medium between the delivery person and the certification requester, so that the transaction between the two, that is, the value. The move can be easily performed.

Further, the paper medium value-giving system can add arbitrary value information specified by the delivery person to the paper medium. Thereby, the paper medium value giving system can, for example, give a high value (for example, a virtual currency balance, a gift certificate amount, etc.) to the paper medium, and in this case, the paper medium has the same value. It has excellent portability compared to real currencies such as banknotes.

Further, for example, a paper medium value-giving system can add value to a paper medium in an arbitrary print state and accurately authenticate the paper medium. As a result, for example, when the paper medium value-giving system gives a high value to a paper medium on which the amount information is not printed, the value of the paper medium cannot be visually determined by humans. It is possible to reduce the risk of theft even if the paper medium is given a high value.

The paper medium value giving system of this embodiment executes a process of giving a virtual currency balance to a paper medium. In this embodiment, as an example of value information, a key for withdrawing the virtual currency balance given to the paper medium is used.

FIG. 19 shows an example of an outline of the entire process executed in the paper medium value-adding system of this embodiment. The value-adding system of this embodiment further includes a virtual currency management server 500 that manages virtual currency. The virtual currency management server 500 of this embodiment is connected to the authentication server 100, the authentication requester terminal 200, and the management terminal 300 via the network 400. Details of the virtual currency management server 500 will be described later with reference to FIG. The authentication server 100 may perform the processing of the virtual currency management server 500.

The management terminal 300 receives input from the delivery person of the image information and value information of the paper medium and the virtual currency balance to be moved to the paper medium, and makes a balance hold request including the input moving balance to the virtual currency management server. Send to 500. The virtual currency management server 500 subtracts the transfer balance included in the balance hold request from the virtual currency balance of the delivery person, and puts the transfer balance in the hold state. The virtual currency management server 500 creates a transfer balance in a hold state, that is, a hold balance withdrawal key for withdrawing the hold balance, and transmits the key to the management terminal 300. The pending balance withdrawal key includes information indicating the corresponding pending balance. The pending balance can be withdrawn only with the pending balance withdrawal key.

Subsequently, the management terminal 300 transmits the input image information and the received pending balance withdrawal key to the authentication server 100. The authentication server 100 holds the received image information on the paper medium in association with the reserved balance withdrawal key. As a result, the transfer balance is given to the paper medium.

A system administrator other than the delivery person may input the image information of the paper medium and the balance to be moved to the paper medium in the management terminal 300. In this case, for example, after the image information of the paper medium and the balance to be moved to the paper medium are registered in the authentication server 100, the paper medium is delivered from the system administrator to the delivery person.

Subsequently, the paper medium is delivered from the deliverer to the certification requester. The authentication requester authenticates the received paper medium using the authentication requester terminal 200. The authentication requester terminal 200 receives input of image information on a paper medium subject to an authentication request from an authentication requester and transmits the input to the authentication server 100.

Specifically, the authentication server 100 searches for image information that matches the received image information from the image information held by the authentication server 100. If the matching image information exists, the authentication server 100 acquires the pending balance withdrawal key corresponding to the image information. The authentication server 100 executes a value guarantee process of transmitting the acquired pending balance withdrawal key to the authentication requester terminal 200.

The authentication requester terminal 200 transmits a hold balance transfer request including the hold balance key to the virtual currency management server 500 according to the instruction of the authentication requester. The virtual currency management server 500 moves the pending balance corresponding to the pending balance transfer key to the authentication requester. Specifically, the virtual currency management server 500 is for processing to move the pending balance to the virtual currency balance of the authentication requester, or for transferring the amount of real currency corresponding to the pending balance to the bank account of the authentication requester. Execute the process to create the transfer data.

In addition, one or more transaction intermediaries may intervene between the authentication requester and the recipient. Each transaction intermediary requests the authentication server 100 for paper-based authentication using the authentication requester terminal 200 possessed by each transaction intermediary. Each transaction intermediary hands over the paper to the next recipient if the authentication is successful. The authentication server 100 performs only the paper-based authentication process and does not execute the value guarantee process in response to the authentication request from the transaction intermediary.

FIG. 20 shows a configuration example of the virtual currency management server 500. The virtual currency management server 500 is composed of a computer having a processor (CPU) 501, a memory 502, an auxiliary storage device 503, an input / output interface 504, and a communication interface 505. The virtual currency management server 500 is owned by, for example, a virtual currency management company. Further, the virtual currency management server 500 does not have to be owned by a specific virtual currency management company, and may be configured by, for example, a plurality of computers connected by a distributed computer network.

The description of the processor 501, the memory 502, the auxiliary storage device 503, the input / output interface 504, and the communication interface 505 is the same as the description of the processor 101, the memory 102, the auxiliary storage device 103, the input / output interface 104, and the communication interface 105, respectively. Therefore, it is omitted.

The memory 502 stores the virtual currency balance management program 511 and the pending balance withdrawal key generation program 512. The virtual currency balance management program 511 executes management processes such as registration, update, and reference of the virtual currency balance stored in the virtual currency balance table 520 described later. The pending balance withdrawal key generation program 512 generates a pending balance withdrawal key.

The auxiliary storage device 503 holds the virtual currency balance table 520. The virtual currency balance table 520 shows the identification information of the customer who holds the virtual currency (login ID to the virtual currency management server 500), the password corresponding to the identification information, the virtual currency balance of the customer, and the virtual state of the customer's hold. The currency balance and the hold balance withdrawal key for withdrawing each of the held virtual currency balance are associated and held.

FIG. 21 shows an example of a process in which the authentication server 100 registers an image and a value on a paper medium in this embodiment. The paper medium registration request program 311 accepts input of one or more paper medium images from the delivery person (S2101). Each input paper medium image is a part or all image of the paper medium. The paper medium registration request program 311 repeats the following steps S2102 to S2111 for each of the input paper medium images. Hereinafter, an example in which the delivery person operates the management terminal 300 will be described.

The paper medium registration request program 311 accepts the input of the balance of the virtual currency to be transferred to the paper medium, the login ID of the delivery person to the virtual currency management server 500, and the password from the delivery person (S2102). The paper medium registration request program 311 transmits a balance hold request including the entered moving balance, login ID, and password to the virtual currency management server 500 (S2103).

The virtual currency balance management program 511 and the hold balance withdrawal key generation program 512 execute the balance hold process (S2104). Specifically, the virtual currency balance management program 511 specifies the combination of the login ID and the password included in the received balance hold request from the virtual currency balance table 520. The virtual currency balance management program 511 subtracts the transfer balance included in the received balance hold request from the virtual currency balance corresponding to the specified combination in the virtual currency balance table 520, and puts the subtracted transfer balance in the hold state.

The hold balance withdrawal key generation program 512 generates a hold balance withdrawal key corresponding to the hold balance, that is, the hold balance withdrawal key, and associates the generated hold balance withdrawal key with the hold balance of the delivery person to create a virtual currency. Store in the balance table 520. The holding balance withdrawal key generation program 512 generates a holding balance withdrawal key different from the holding balance withdrawal key already stored in the virtual currency balance table 520.

In step S2104, if the combination of the received identification information and the password is not included in the virtual currency balance table 520, or if the virtual currency balance of the delivery person is less than the received transfer balance, the pending balance withdrawal key generation program 512 , The pending balance withdrawal key is not generated, and the error message is sent to the management terminal 300.

Subsequently, the virtual currency balance management program 511 transmits the held balance withdrawal key to the management terminal 300 (S2105). The paper medium registration request program 311 makes a paper medium registration request including the paper medium image, the received pending balance withdrawal key, and the value issuer ID which is the ID of the delivery person who made the input in S2102. It is transmitted to 100 (S2106).

The paper medium registration request program 311 may further accept input of the authentication requester ID, validity period, authentication requester information, delivery person information, etc. from the delivery person in step S2102. At this time, the paper medium registration request program 311 further includes the input information in the paper medium registration request in step S2106.

Subsequently, the paper medium image registration program 112 extracts the image feature amount from the paper medium image included in the received paper medium registration request (S2107). The feature amount extraction process may be performed by the paper medium registration request program 311 in step S2101, and the feature amount extracted by the paper medium registration request program 311 in step S2106 may be included in the paper medium registration request. In this case, step S2107 is omitted.

The paper medium image registration program 112 issues a paper medium ID, associates the issued paper medium ID with the extracted feature amount and the information included in the paper medium registration request, and stores the printed paper medium ID in the paper medium table 140 (S2108). The balance withdrawal key is stored in the value information column 143.

For example, when the information of the paper medium having the same or similar feature amount as the extracted feature amount is already stored in the paper medium table 140, the paper medium image registration program 112 does not execute the registration process in step S2108. .. Specifically, for example, when the norm of the difference between the two feature amounts is equal to or less than a predetermined threshold value, the paper medium image registration program 112 determines that the two feature amounts are the same or similar.

The paper medium image registration program 112 transmits a paper medium registration response indicating the registration result in step S2108 to the management terminal 300 (S2109). The paper medium registration request program 311 outputs the registration result indicated by the received paper medium registration response to the input / output interface 304 (S2110). The paper medium registration request program 311 transfers the received paper medium registration response to the virtual currency management server 500 (S2111).

The virtual currency balance management program 511 refers to the registration result indicated by the received paper medium registration response. If it is found that the registration has not been completed, the virtual currency balance management program 511 adds the pending balance in the virtual currency balance table 520 to the corresponding virtual currency balance, and the pending balance and the pending corresponding to the pending balance. The balance withdrawal key is deleted from the virtual currency balance table 520. If the virtual currency balance management program 511 does not receive the paper medium registration response even after a predetermined time has elapsed from the process of step S2105, it is assumed that the registration has not been completed, and the above-mentioned pending balance and pending balance withdrawal key have not been completed.

FIG. 22 shows an example of the authentication process by the paper medium value-adding system. Since the processes of steps S1001 to S1012 are the same as those in FIG. 10, the description thereof will be omitted. The following processes of steps S1002 to S1012 and steps S2213 to S2217 are executed for each paper medium image captured in step S1001. Hereinafter, the processing after the completion of steps S1001 to S1012 will be described.

The value guarantee program 114 refers to the paper medium table 140 only when the authentication result is successful, and obtains the pending balance withdrawal key corresponding to the paper medium for which the authentication is successful from the value information column 143 (S2213). ..

Further, the value guarantee program 114 issues a value guarantee number and stores the issued value guarantee number in the value guarantee number column 147 corresponding to the specified paper medium ID. The value guarantee program 114 changes the value of the value guarantee status column 146 corresponding to the specified paper medium ID to "value guaranteed".

Subsequently, the paper medium image authentication program 113 transmits a paper medium authentication result notification including the authentication result registered in step S1010 to the authentication requester terminal 200 (S2214). If the authentication result is successful, the paper medium image authentication program 113 further includes the acquired pending balance withdrawal key in the paper medium authentication result notification. The authentication server 100 transmitting the pending balance withdrawal key to the authentication requester terminal 200 is an example of the value assurance process in this embodiment.

The paper medium image transmission program 213 updates the authentication status of the paper medium according to the authentication result indicated by the paper medium authentication result notification (S2215). Specifically, for example, the paper medium image transmission program 213 changes the authentication status of the paper medium image in the paper medium image storage area 215 to "certified (OK)" when the authentication result is successful. If the authentication result is unsuccessful, the authentication status of the paper medium image in the paper medium image storage area 215 is changed to "certified (NG)". Further, the paper medium image transmission program 213 may display the balance withdrawal key together with the authentication status of the paper medium in response to the request from the authentication requester when the authentication result is successful.

Subsequently, the paper medium image transmission program 213 transmits a pending balance transfer request including the pending balance withdrawal key to the virtual currency management server 500 in response to the request from the authentication requester (S2216). When adding the pending balance to the virtual currency balance of the authentication requester, the paper medium image transmission program 213 accepts the input of the login ID and password of the authentication requester to the virtual currency management server 500 from the authentication requester. Include the entered login ID and password in the pending balance transfer request.

In addition, when the real currency corresponding to the pending balance is transferred to the bank account of the authentication requester, the paper medium image transmission program 213 transfers the transfer destination account information of the authentication requester (bank code, account number, contact of the authentication requester). The input of the destination etc.) is accepted from the authentication requester, and the input transfer destination account information is included in the pending balance transfer request.

When the real currency corresponding to the pending balance is transferred to the bank account of the authentication requester, the paper medium image transmission program 213 suspends the authentication requester ID to the authentication server 100 of the authentication requester instead of the transfer destination account information. It may be included in the balance transfer request. At this time, the virtual currency balance management program 511 transmits the received authentication requester ID to the authentication server 100. The management information operation program 115 acquires the transfer destination account information from the transfer account column 137 corresponding to the authentication requester ID in the authentication requester history table 130, and transmits the transfer destination account information to the management terminal 300.

Subsequently, the virtual currency balance management program 511 executes the pending balance transfer process (S2217). When the real currency corresponding to the pending balance is transferred to the bank account or the like of the authentication requester, the following processing is executed in step S2217.

The virtual currency balance management program 511 creates transfer data corresponding to the transfer destination account information in the virtual currency balance management program 511. When the transfer data is normally created, the virtual currency balance management program 511 deletes the pending balance key and the pending balance corresponding to the pending balance key in the virtual currency balance table 520. If the transfer corresponding to the transfer data is not executed even after a predetermined period has passed since the transfer data was normally created, the virtual currency balance management program 511 will use the deleted hold balance key and hold balance. Restore it and delete the transfer data. If the transfer data is not created normally, the virtual currency balance management program 511 sends an error message to the authentication requester terminal 200.

When the pending balance is added to the virtual currency balance of the authentication requester, the following processing is executed in step S2217. The virtual currency balance management program 511 determines whether or not the combination of the received login ID and password exists in the virtual currency balance table 520.

If the combination exists, the virtual currency balance management program 511 adds the pending balance corresponding to the pending balance key in the virtual currency balance table 520 to the virtual currency balance corresponding to the received login ID, and adds the pending balance key. And the pending balance corresponding to the pending balance key is deleted. If the combination does not exist, the virtual currency balance management program 511 sends an error message to the authentication requester terminal 200.

If the authentication result is successful in step S2214, the authentication server 100 does not include the pending balance withdrawal key in the paper-based authentication result notification, but acquires information indicating the pending balance from the pending balance withdrawal key. Information indicating the acquired pending balance may be included in the paper authentication result notification.

At this time, in step S2216, the authentication requester terminal 200 includes the received paper medium authentication result notification in the pending balance transfer request. The virtual currency management server 500 transmits the paper medium authentication result notification received from the authentication requester terminal 200 to the authentication server 100, and the authentication server 100 determines whether or not the received paper medium authentication result notification is valid. .. If the authentication server 100 determines that it is valid, it transmits the pending balance withdrawal key corresponding to the paper medium to the virtual currency management server 500, and transitions to step S2217.

If the authentication server 100 determines that the error message is not valid, the authentication server 100 transmits an error message to the virtual currency management server 500, and the virtual currency management server 500 transmits the error message to the authentication requester terminal 200. By such processing, the pending balance withdrawal key does not leak to the outside of the authentication server 100, so that the security level can be increased.

Further, in the present embodiment, the virtual currency management server 500 may not generate the hold balance withdrawal key, and instead of the hold balance withdrawal key, the virtual currency given to the paper medium, that is, the hold balance itself may be exchanged.

As described above, the paper medium value-adding system of this embodiment can transfer the value of the virtual currency to any paper medium and accurately execute the authentication process of the paper medium. As a result, the paper medium value-imparting system of this embodiment allows the delivery person to safely pass the virtual currency balance held by the delivery person to the authentication requester who holds the virtual currency, so that it is smooth. Transactions are realized.

The paper medium value-adding system of this embodiment executes a process of adding value as a gift certificate to the paper medium. The gift certificate is an example of a paper-type prepaid payment method, and the paper medium value-imparting system of the present embodiment can impart value as any paper-type prepaid payment method to the paper medium.

FIG. 23 shows an example of an outline of the entire process executed in the paper medium value-adding system of this embodiment. The authentication server 100 is installed in the authentication center or the issuer of the gift certificate, the authentication requester terminal 200 is installed in the store where the gift certificate is used, and the management terminal 300 is installed in the issuer of the gift certificate.

First, the management terminal 300 receives the input of the image information of the paper medium and the gift certificate amount which is the value information from the system administrator of the issuer of the gift certificate from the system administrator, and the input information is received by the authentication server 100. Send to. The authentication server 100 holds the received image information of the paper medium and the amount information in association with each other. As a result, the value indicated by the amount of the gift certificate is given to the paper medium, that is, the paper medium becomes a gift certificate having the value of the amount.

Subsequently, the paper medium is handed over from the issuer to the customer. Subsequently, the customer hands over the paper medium to the store staff and purchases the product. The store staff authenticates the received paper medium using the authentication requester terminal 200. The authentication requester terminal 200 receives input of image information on a paper medium from the authentication requester, and transmits the input information to the authentication server 100.

The authentication server 100 searches for image information that matches the received image information from the image information held by the authentication server 100. When the matching image information exists, the authentication server 100 acquires the amount information corresponding to the image information and executes the value guarantee process of creating the transfer data corresponding to the acquired amount.

Specifically, the value guarantee program 114 executes the value guarantee process as follows. The value guarantee program 114 acquires the name from the name column 134, the transfer destination account information from the transfer account column 137, and the gift certificate amount from the value information column 143, which correspond to the paper medium ID specified in the authentication process. .. The value guarantee program 114 creates transfer data in which the specified paper medium ID is associated with the acquired name, the transfer destination account number, and the gift certificate amount.

Further, the value guarantee program 114 issues a value guarantee number and stores the issued value guarantee number in the value guarantee number column 147 corresponding to the specified paper medium ID. The value guarantee program 114 changes the value of the value guarantee status column 146 corresponding to the specified paper medium ID to "value guaranteed". The value guarantee program 114 transmits the generated transfer data to the management terminal 300, for example, periodically or in response to a request from the management terminal 300.

In addition, one or more transaction intermediaries may intervene between the authentication requester and the recipient. Each transaction intermediary requests the authentication server 100 for paper-based authentication using the authentication requester terminal 200 possessed by each transaction intermediary. Each transaction intermediary hands over the paper to the next recipient if the authentication is successful. The authentication server 100 performs only the paper-based authentication process and does not execute the value guarantee process in response to the authentication request from the transaction intermediary.

By the process described above, the paper medium value-giving system of this embodiment gives value as a gift certificate to any paper medium, accurately executes the authentication process of the paper medium, and further creates transfer data to the store. can do.

Although the paper medium value giving system in the client-server method is described in the present embodiment, the paper medium value giving system may be realized by a P2P method such as a blockchain, for example. In this case, for example, each of the plurality of terminals (nodes) installed in various places bears a part or all of the functions of the authentication server 100, the authentication requester terminal 200, the management terminal 300, and the virtual currency management server 500.

When there are a plurality of terminals connected via a network that function as the authentication server 100 (each of the plurality of terminals is responsible for a part of the functions of the authentication server 100), for example, the blockchain is formed by the plurality of terminals. It may be configured and the delivery history of the paper medium may be recorded in a block of the blockchain. This makes it possible to guarantee the distribution process of the paper medium more accurately, especially when there is a transaction intermediary between the delivery person and the certification requester. Further, for example, when there are a plurality of terminals that function as the virtual currency management server 500 (each of the plurality of terminals bears a part of the functions of the virtual currency management server 500), for example, the blockchain is formed by the plurality of terminals. It may be configured and the transaction history of the virtual currency may be recorded in the block of the blockchain.

Further, as described above, the authentication server 100 may execute the originality proof of the paper medium as the value guarantee process. Specifically, for example, when the banknote on which the identification number is described is the paper medium of the present embodiment, for example, the paper medium table 140 of the authentication server 100 has the paper medium ID which is the identification number of the banknote and the banknote. A part or all of the image information of the banknote including the described identification number is stored in association with the image information. The authentication server 100 receives, from the authentication requester terminal 200, image information of a part or all of the banknote including the identification number written on the banknote, image information corresponding to the identification number stored in the paper medium table 140, and image information corresponding to the identification number. If the authentication is successful, the originality of the banknote is verified. By this process, the authentication server 100 also functions as a banknote classifier.

Further, the medium used for the paper medium value-adding system of the present embodiment is not limited to the paper medium. For example, media such as cloth, stone, and wood may be used instead of paper media. That is, instead of the image on the paper medium, the image of the medium such as cloth, stone, and wood and the value associated with the image are registered in advance in the authentication server 100, and the authentication server 100 receives the medium. The authentication process and the value assurance process may be performed on the image of. In this case, as an image feature amount of cloth, stone, wood, etc., information indicating physical properties peculiar to cloth, stone, wood, etc. (information that does not change by printing or printing, for example, a shape pattern, etc.) is used.

Hereinafter, the differences between the present embodiment and the prior art documents will be described. The technique described in Patent Document 1 is a technique for ensuring the originality of various types of paper to be inspected, and what is the paper medium value giving system of the present embodiment that gives value to a paper medium and executes certification? The idea is different. The technique described in Patent Document 2 is a technique for executing the settlement of a gift certificate in which a security medium is embedded in advance, and is a technique for imparting value information to a paper medium which has not been subjected to special processing in advance. The technical idea is different from the paper media value-giving system. The technique described in Patent Document 3 is a system for issuing non-counterfeitable hard copy securities using special paper, and the paper of the present embodiment which gives value information to a paper medium which has not been specially processed in advance. The technical idea is different from the medium value-giving system.

The technique described in Patent Document 1 aims to realize a paper identification and verification technique, which is extremely difficult to spoof, while satisfying the elements of "convenience of being easy anywhere" and "low cost". .. On the other hand, the technique described in Patent Document 2 uses a gift certificate in which a security medium is embedded in advance, which is contrary to the purpose of the technique described in Patent Document 1, and therefore the technique described in Patent Document 1. It is not easy to combine the technique described in Patent Document 2 with the technique described in Patent Document 2. In addition, the technology described in Patent Document 3 states that "a potential customer applies for the purchase of securities, purchases the securities, transfers the purchased securities to a trustee, prints out and prints out the purchased non-counterfeit hard copy securities. The purpose is to provide a securities issuing system equipped with a plurality of issuing machines installed at various locations convenient for redistribution of non-counterfeit hard copy securities to the system. ”This is the technique described in Patent Document 1. Therefore, there is no motivation to combine the technique described in Patent Document 1 with the technique described in Patent Document 3.

Although the present invention has been described in detail with reference to the accompanying drawings, the present invention is not limited to such a specific configuration, and various changes and equivalents within the scope of the attached claims are made. It includes the composition.

This application claims the priority of PCT / JP2016 / 050824, which is an international patent application filed on January 13, 2016, and incorporates it into this application by referring to its contents.
