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 photographed by the paper medium image photographing program 212 and the authentication status of the paper medium image.

The management terminal 300 includes 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 a system management facility, for example. The authentication center and the system management facility may be the same facility. 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 has the management terminal 300.

The descriptions of the processor 301, the memory 302, the auxiliary storage device 303, the input / output interface 304, and the communication interface 305 are the same as the descriptions 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 authentication 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 a paper medium image and paper medium value information.

May operate in separate threads on a single computer, or may operate on a virtual computer constructed on a plurality of physical computer resources.

FIG. 2 shows an example of an outline of the entire processing executed in the paper medium value assigning system of this embodiment. First, the management terminal 300 receives input of image information and value information of a paper medium from a paper medium transfer person, and transmits the input information to the authentication server 100. The authentication server 100 holds the received image information and value information of the paper medium in association with each other. Thereby, value is given to the paper medium.

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

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

Subsequently, a paper medium is delivered from the delivery person to the authentication requester in order to execute the transaction. The authentication requester uses the authentication requester terminal 200 to authenticate the received paper medium. 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 the image information held by the authentication server 100 for an image that matches the received image information. The authentication server 100 acquires value information corresponding to the matched image information, and executes processing to guarantee the value indicated by the acquired value information to the paper medium.

Specifically, when a virtual currency balance is given to a paper medium, a key transmission process for extracting the virtual currency balance from the authentication server 100 to the authentication requester terminal 200 is a value guarantee process for the paper medium. It is an example. In addition, when the paper medium is a work of art, and original proof information is given to the paper medium, the original proof data creation process of the work of art by the authentication server 100 is an example of a value guarantee process for the paper medium. .

It should be noted that one or more transaction intermediaries may be interposed between the authentication requester and the recipient. Each transaction intermediary requests the authentication server 100 to perform paper medium authentication using the authentication requester terminal 200 possessed by each transaction intermediary. Each transaction intermediary delivers a paper medium to the next recipient when the authentication is successful. In response to the authentication request from the transaction intermediary, the authentication server 100 performs only the paper medium authentication process and does not execute the value guarantee process.

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 that stores identification information of the authentication requester, and an update count column 122 that stores 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 includes, 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, a contact column 138, And a registration date / time column 139. The information stored in the authentication requester history table 130 is information transmitted from the authentication requester terminal 200, for example.

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

The representative name column 136 stores the representative name of the organization to which the authentication requester belongs. The bank account column 137 stores bank account information such as the bank code, deposit type code, and account number of the bank account of the authentication requester. The contact address field 138 stores a contact information such as the telephone number or mail address of the authentication requester. The registration date / time column 139 stores the date / 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 includes, for example, a paper medium ID column 141, an image information column 142, a value information column 143, a value issuer ID column 144, an authentication requester ID column 145, a value guarantee status column 146, a value guarantee number column 147, It includes a verification number column 148, a validity period column 149, a usage restriction code column 161, an authentication requester information column 162, and a transferee information column 163.

The paper medium ID column 141 stores paper medium identification information. The image information column 142 stores the paper medium image and the feature amount of the paper medium image. Note that the feature amount of the paper medium image in the present embodiment includes information according to physical properties unique to the paper generated in the process of generating paper (excluding printing). Even when the print content of a certain paper medium is copied to another paper medium, the feature quantities of both paper media are different. Therefore, by executing authentication using the feature amount, the paper medium value assigning system can accurately execute authentication processing for all paper media.

For example, a feature amount indicating a paper fiber pattern constituting a paper medium is an example of the feature amount, and indicates a physical property generated in the process of generating paper. For example, even if printing or smearing occurs on a paper medium, the paper fiber pattern does not change, and the authentication process for the paper medium can be executed accurately. Even if a special fiber pattern or the like is not embedded in the paper, the paper has a random pattern in which plant fibers overlap in an irregular shape. By using the random pattern as the paper fiber pattern, the authentication process can be accurately executed even for a paper medium that has not been subjected to special processing in advance.

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

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

The collation count column 148 stores the number of times authentication processing has been executed for the corresponding paper medium. The validity period column 149 stores the validity period of the corresponding paper medium. The effective period indicated by the effective 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 end, it indicates that there is no restriction on the other. The use restriction code column 161 stores the use 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 transmitting a warning message about the authentication of the corresponding paper medium to the management terminal 300.

The authentication requester information column 162 stores information specifying the authentication requester, such as biometric information of the authentication requester (palm vein, fingerprint, pupil, etc.). The delivery person information column 163 stores information specifying the delivery person, such as the delivery person's biometric information and the imprint of the delivery person's seal. Each of the authentication requester ID, the authentication requester information, and the transferee information is an example of operator information of an operator who operates the paper medium value assignment system.

Note that the paper medium table 140 may further include, for example, an authentication valid place field. The authentication valid place column stores, for example, information indicating the range of places where the authentication of the corresponding paper medium is valid. That is, if the position of the authentication requester terminal 200 at the time of transmitting the paper medium authentication request is not included in the location range indicated by the authentication valid location column corresponding to the paper medium, the authentication server 100 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 includes, for example, a paper medium ID field 151, a collation number field 152, an authentication requester ID field 153, an authentication requester terminal ID field 154, a shooting date / time field 155, a paper medium image field 156, and a rejection reason. Column 157 is included.

The disapproval reason column 157 stores the disapproval reason when the result in the authentication process is disapproval.

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 an application according to the input from the authentication requester, and outputs a start screen for new registration of terminal information (S701). Note that 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 in accordance with 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 in accordance with the instruction on the new registration screen. The terminal information registration request program 211 transmits a terminal information registration request including the authentication requester ID and password input by the authentication requester to the authentication server 100 (S703).

The registration information check program 111 executes terminal information registration processing (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 sets the password included in the received terminal information registration request as a password. Stored in the column 133 and the current date and time are stored in the registered date and time column 139. Also, 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.

In step S703, the terminal information registration request program 211 further accepts input of information such as the name, address, representative name, transfer account information, and contact information of the authentication requester from the authentication requester. May be transmitted 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, for example, the content indicating the error is input / output interface (display screen). Then, the process proceeds 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 an application and outputs a start screen according to the input from the authentication requester (S801).

The authentication requester enters 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 the authentication requester ID and password input by the authentication requester to the authentication server 100 (S802). The registration information check program 111 includes the authentication requester ID and password included in the received terminal information registration request, the authentication requester ID stored in the authentication requester ID column 131, and the password stored in the password column 133, respectively. In comparison, a 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 a 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 input to the input / output interface 204 (display screen). Output.

FIG. 9 shows an example of processing in which the authentication server 100 registers an image and value of a paper medium. The paper medium registration request program 311 receives 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 processing from step S902 to step S907 described below for each input paper medium image.

The paper medium registration request program 311 receives an 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 that is the ID of the delivery person who performed the input in S902. The request is transmitted to the authentication server 100 (S903).

In step S902, the paper medium registration request program 311 receives further input from the delivery person such as the authentication requester ID, the validity period, the authentication requester information, the delivery person information, the authentication valid time, and the authentication valid place. Also 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 an image feature amount from the paper medium image included in the received paper medium registration request (S904). Note that the paper medium registration request program 311 may perform feature amount extraction processing 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, stores the issued paper medium ID, the extracted feature amount, and information included in the paper medium registration request in association with each other in the paper medium table 140 (S905).

For example, when information on a paper medium having the same or similar feature quantity as the extracted feature quantity 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 two feature amounts is equal to or less than a predetermined threshold, 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 authentication processing by the paper medium value assignment system. The paper medium image shooting program 212 uses the camera 206 to capture one or more authentication target paper images (S1001). The paper medium image photographing program 212 stores each paper medium image in the paper medium image storage area 215 in association with the authentication status. Note that the authentication status of each paper medium image at the time of step S1001 is “waiting for transmission”.

Hereinafter, the following processes in steps S1002 to S1015 are executed for each paper medium image photographed in step S1001. Further, the processes in steps S1002 to S1015 may be executed collectively for a plurality of paper medium images photographed 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). Note that 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 field 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 transmission of the paper medium image check request including the paper medium image in step S1002, the paper medium image transmission program 213 stores 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 determine the paper medium. An image authentication process 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 specifies the paper medium ID corresponding to the received paper medium image. Details of the authentication processing 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). Note that the authentication result in step S1007 includes, for example, information indicating whether or not the authentication is successful. If the authentication is successful, the authentication result in the paper medium table 140 authenticated as the same as the paper medium image is obtained. It further includes image information. If authentication fails (denied), the processing in 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 a paper medium image authentication process in accordance with, for example, an input from the delivery person (S1008). 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).

Only when the authentication result is successful, the value guarantee program 114 refers to the paper medium table 140 and executes value guarantee processing for the paper medium (S1013). Instead of step S1013, after step S1008, The value guarantee program 314 may execute value guarantee processing, include the processing result in the paper medium authentication result registration request in step S1009, and transmit the 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 in accordance with the authentication result indicated by the paper medium authentication result notification (S1015). Specifically, for example, when the authentication result is successful, the paper medium image transmission program 213 changes the authentication status of the paper medium image to “authenticated (OK)”, and the authentication result is unsuccessful. In this case, the authentication status of the paper medium image is changed to “authenticated (NG)”.

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

Also, for example, the authentication process in the management terminal 300 may be executed by a batch process every time a certain time or authentication process for a certain number of paper medium 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 in step S1006 without waiting for the reception of the paper medium authentication result registration request in step S1009.

Further, after the authentication process by the management terminal 300, the authentication process by the authentication server 100 may be executed. Hereinafter, differences from the above-described 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 in step S1006, and registers the processing result in step S1010. When the authentication result failure indicated by the paper medium authentication result registration response received in step S1009 is unsuccessful, the paper medium image authentication program 113 does not execute the process of step S1006 and registers the authentication result indicating that the authentication has failed in step S1010. Then, the process of step S1011 is not executed.

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

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. 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 information necessary for displaying the error screen in the login response, and the management information operation request program 313 includes information included in the login response. Use to output an error screen.

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

The management screen further includes an area for receiving an input of an execution instruction for a paper medium image display process, and an area for receiving an input of an execution instruction for a value guarantee process. These areas are shown in FIG. Used in processing.

The management information operation request program 313 accepts an input of 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 management information operation program 115 transmits a management information operation response including a management information operation result according to the operation content indicated by the received management information operation request to the management terminal 300 (S1111). The management information operation request program 313 displays the operation result included in the received management information operation response (S1112).

The management information operation program 115 transmits a logout response including information necessary for displaying the login screen to the management terminal 300 (S1115). The management information operation request program 313 outputs a login screen according to the information included in the received logout response (S1116).

FIG. 12 shows an example of the overall processing of the authentication requester terminal 200. The process of FIG. 12 corresponds to the process of the authentication requester terminal 200 in FIGS. When the authentication requester terminal 200 is activated, the terminal information registration request program 211 outputs an activation screen. For example, according to an instruction from the authentication requester, whether or not the information of the authentication requester terminal 200 has been registered in the authentication server. (S1201) When the information of the authentication requester terminal 200 is not registered in the authentication server 100 (S1201: None), the terminal information registration request program 211 outputs a new registration screen (S1202), and the authentication requester ID And password input.

If the information of the authentication requester terminal 200 has been registered in the authentication server 100 (S1201: Yes), the input of the authentication requester ID and password is accepted, and the process proceeds to step S1203. The terminal information registration request program 211 transmits a terminal information check request including the authentication requester ID and password to the authentication server 100 (S1203).

The terminal information registration request program 211 receives the processing result of the terminal information authentication process from the authentication server 100 (S1204). If the authentication is successful (S1204: OK), the process proceeds to step S1205. If the authentication fails (S1204: NG), the process proceeds to step S1201.

The terminal information registration request program 211 outputs a menu screen and selects a menu according to a request from the authentication requester (S1205). Details of the menu screen will be described later with reference to FIG. 18B. When the “paper medium image shooting” button is operated from the menu screen (S1205: paper medium shooting), the paper medium image shooting program 212 executes a paper medium image shooting process (S1206), and steps after the shooting process ends. The process returns to S1205.

When a “paper medium image transmission” button is operated from the menu screen (S1205: paper medium image transmission), the paper medium image transmission program 213 executes a paper medium image transmission process (S1207), and after the transmission process ends. The process returns to step S1205. When the “confirm paper medium status” button is operated from the menu screen (S1205: paper medium status confirmation), the paper medium status confirmation program 214 executes status confirmation processing (S1208), and after the status confirmation processing is finished, step S1205 is performed.

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 medium 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 when no image is selected (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 medium image transmission screen will be described later with reference to FIG. 18B.

Subsequently, the paper medium image transmission program 213 executes the processing of step S1405 and step 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). If the cancel button is operated (S1405: YES), the paper medium image transmission program 213 stops the image transmission process being executed and the transmission process of all untransmitted images, and the process proceeds 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 for 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 verification number. The paper medium image authentication program 113 authenticates the issued verification number (hereinafter referred to as the first verification number) in the verification number field 152 and the authentication requester ID that is logged in the authentication requester terminal 200 that transmitted the paper medium image. In the requester ID field 153, the ID of the authentication requester terminal 200 that transmitted the paper medium image is stored in the authentication requester terminal ID field 154, and the shooting date and time included in the received paper medium image is stored in the shooting date and time field 155. The medium image is stored in the memory 202 or the auxiliary storage device 203, respectively. Thereafter, 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, 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 the received paper medium image is authenticated (S1502).

An example of the paper medium image authentication process in step S1502 will be described. For example, the paper medium image authentication program 113 calculates a norm of a difference between the feature amount of the received paper medium image and each feature amount stored in the paper medium table 140. The paper medium image authentication program 113 calculates a value obtained by substituting each of the calculated norms into a predetermined decreasing function as the image similarity. In other words, the smaller the norm of the feature amount difference, 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 image search program 113 searches the paper medium table 140 and has the same paper medium ID as the received paper medium ID. The similarity with the received paper medium image may be calculated for only the medium image. When information indicating a paper medium ID such as a character or a two-dimensional code is printed or printed on a paper medium, the paper medium image authentication program 113 performs character recognition, two-dimensional code decoding, or the like, 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 refusal that the same paper medium ID does not exist may be recorded in the refusal 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 verification number field 148 corresponding to the paper medium ID, and the first verification number The paper medium ID is stored in the paper medium ID column 151 corresponding to.

Subsequently, the paper medium image authentication program 113 determines whether each of the calculated similarities is equal to or higher than a predetermined authentication threshold (S1503). If all the calculated similarities are less than the predetermined authentication threshold (S1503: NO), the reason for refusal indicating that the paper medium image similar to the received paper medium image is not registered in the paper medium table 140 is displayed. The result is stored in the non-repudiation reason column 157 corresponding to one verification number (S1504), and the process proceeds to step S1508.

If there is a similarity that is 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 selected similarity in the paper medium table 140 (hereinafter, the paper medium is referred to as a first paper medium, and the image on the first paper medium is referred to as a first paper medium image). The paper medium ID notification, the received paper medium image, and the authentication result indicating that the authentication is successful are transmitted to the management terminal 300. If a value indicating a caution message is stored in the use restriction code column 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 from the management terminal 300 from the management terminal 300, and determines whether or not the authentication result is successful (S1505).

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

In step S1503, the paper medium image authentication program 113 includes the authentication requester ID field 145, the value guarantee number field 147, the verification number field 148, the validity period field 149, the usage restriction code field 161, and the like. Authentication processing using at least one piece of information in the authentication requester information column 162 and the transferee information column 163 may be further performed. The paper medium image authentication program 113 transmits a paper medium authentication notification to the management terminal 300 only when the authentication process is successful.

Note that the paper medium image authentication program 113 may execute an authentication process using information described below in addition to the authentication process using the similarity of the paper medium image in steps S1502 to S1503. If at least one reason for refusal is recorded in the authentication process, the paper medium image authentication program 113 does not transmit the paper medium authentication notification to the management terminal 300 and proceeds to step S1508. The paper medium image authentication program 113 can ensure 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, for example, the authentication requester ID of the authentication requester who transmitted the paper medium image and the authentication requester The authentication requester ID stored in the ID column 145 is compared. If the authentication requester ID does not match in the comparison, the paper medium image authentication program 113 stores a rejection reason indicating that the authentication requester does not match in the rejection reason column 157 corresponding to the first verification number.

When the number of verifications indicated in the first paper medium image verification count column 148 is equal to or greater than a predetermined threshold, the paper medium image authentication program 113 performs verification that exceeds the allowable number of times for the first paper medium, for example. The reason for refusal indicating that this has been done is stored in the refusal reason column 157 corresponding to the first reference number. The threshold value may be different for each paper medium. 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 verification number the reason for refusal indicating that the value of the paper medium has already been guaranteed. Stored in the rejection reason column 157.

If the value in the validity period column 149 of the first paper medium image is not a null value, for example, the paper medium image authentication program 113 compares the current date and time with the date and time indicated in the validity period column 149 of the first paper medium image, It is determined whether or not the current date is within the validity period. If the current date and time is not within the valid period, the paper medium image authentication program 113 stores a denial reason indicating that the authentication time is not within the valid period in the denial reason column 157 corresponding to the first verification number.

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

If 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 a palm vein, the paper medium image capturing program 212 captures an image of the authentication requester's palm vein using the camera 206 in accordance with an 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 palm vein image with the palm vein image stored in the authentication requester information field 162. When the paper medium image authentication program 113 determines that the palm vein images do not match in the comparison, the paper medium image authentication program 113 stores a rejection reason indicating that the authentication requester information does not match in the rejection reason column 157 corresponding to the first verification number. To do.

If the authentication requester information is printed on a paper medium such as a seal stamp stamped on the paper medium, the paper medium image authentication program 113 does not transmit an authentication requester information transmission request, The authentication requester information may be extracted from the paper medium.

The processing when the delivery person information column 163 is not a null value is the same as the processing 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 field 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 field. If it is not included in the range of the indicated location, for example, the paper medium image authentication program 113 stores a rejection reason indicating that the authentication request has not been executed at the authentication valid location in the rejection reason column 157 corresponding to the first verification number. To do.

Note that the paper medium image authentication program 113 may change the authentication process to be executed in accordance with 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 the first paper medium is 1000 yen or less, the paper medium image authentication program 113 executes authentication processing based only on the similarity of the paper medium images. For example, when the amount of the first paper medium is more than 1000 yen and less than or equal to 10,000 yen, 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 authentication process. For example, when the amount of the first paper medium is more than 10,000 yen, the paper medium image authentication program 113 performs the paper processing in addition to the authentication process based on the similarity of the paper medium image and the authentication process based on the reception time of the paper medium image check request. An authentication process based on the location information of the authentication requester terminal 200 at the time of transmitting the medium image check request is executed.

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 a rejection reason indicating that the authentication result in the management terminal 300 is unsuccessful. The result is stored in the non-repudiation reason field 157 corresponding to one verification number (S1506). When the paper medium image authentication program 113 receives a specific rejection reason from the management terminal 300, the received rejection reason may be stored in the rejection reason column 157 corresponding to the first reference number. .

If the authentication result from the management terminal 300 is successful (S1505: YES), the value guarantee program 114 acquires value information corresponding to the first paper medium image from the value information column 143, and executes value guarantee processing. (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. The value in the value guarantee status column 146 is changed to “value guaranteed”. Note that the value guarantee processing 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 an authentication result to the authentication requester terminal 200 to the authentication requester terminal 200 (S1508). If the paper medium image authentication program 113 denies authentication, the paper medium image authentication program 113 may further include a rejection reason in the paper medium authentication result notification.

FIG. 16 shows an example of a 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 in FIG. 16 corresponds to the processes in 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 an input of a login ID and a 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 input login ID and password combination is not valid (S1602: login failure), the process returns to step S1601. When the input login ID and password combination is valid (S1602: login success), the management information operation request program 313 outputs a management screen (S1603).

When the management information operation request program 313 receives a logout request from the delivery person (S1603: logout), the logout process is executed, a logout screen is output (S1604), and the authentication process is terminated. The processing in steps S1601 to S1604 is the same as the processing in steps S1101 to S1108 and S1113 to S1116 in FIG.

When the delivery person instructs execution of the paper medium image display process (S1603: image display), the paper medium authentication registration program 312 outputs a paper medium image display screen (S1605). The paper medium image display screen includes, for example, an area for displaying a paper medium image stored in the authentication result storage area 315, an area for displaying an authentication result of each paper medium image by the management terminal 300, and an authentication by the management terminal 300. It includes an area for inputting an authentication result of each paper medium image that has not been processed, an area for displaying a caution message indicated by the 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 medium images is input by the delivery person (S1607: authentication result), the paper medium authentication registration program 312 converts each of the input authentication results into the one or more authentication result storage areas 315. The paper medium image is stored in association with it (S1608), and the process proceeds to step S1603.

In step S1607 described above, the authentication result obtained by visually confirming the delivery person is input by manual processing, but may be executed by automatic processing. For example, when the seal of the delivery person is stamped on the paper medium in advance and the correspondence information between the paper medium and the seal is stored in the auxiliary storage device 303, the paper medium authentication registration program 312 extracts the seal 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 correspondence information. In addition to the authentication process by the authentication server 100, the management terminal 300 performs another authentication process, thereby improving the security level of authentication.

In step S1603, when the delivery person gives an instruction to execute the value guarantee process (S1603: value guarantee), the value guarantee program 314 executes the value guarantee process (S1606), and the process proceeds to step S1603.

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

The value guarantee program 314 receives value information included in the paper medium table 140 of each of the one or more paper medium images from the authentication server 100, and executes value guarantee processing for each of the one or more paper medium images. Note that 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 does not transmit the value information transmission request. You may perform a value guarantee process using the said 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 to the management terminal 300, and the authentication server 100 is included in the image information input to the management terminal. Image feature values and value information are registered in advance. The authentication server 100 compares the feature amount indicated by the paper medium image received from the authentication requester terminal 200 with the feature amount registered in advance, and executes an authentication process based on the comparison result. If the authentication process is successful, the authentication server 100 executes a value guarantee process using corresponding value information registered in advance.

Thereby, the paper medium value imparting system of the present embodiment can give value to any paper medium without performing a special process, 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 possessed by the delivery person, the delivery person can authenticate every paper medium with high accuracy on the spot without performing special processing. It can be transformed into a possible value medium. In addition, since the paper medium value assignment system of this embodiment is used, a transaction between both parties is established by the movement of the paper medium between the delivery person and the authentication requester. The movement can be performed easily.

Also, the paper medium value assigning system can add arbitrary value information designated by the delivery person to the paper medium. Thereby, the paper medium value assigning system can give a high value (for example, virtual currency balance, gift certificate amount, etc.) to the paper medium, and in this case, the paper medium has an equivalent value. It is more portable than real currencies such as banknotes.

Also, for example, the paper medium value assigning system can give a value to a paper medium in an arbitrary print state and accurately execute authentication of the paper medium. Thereby, for example, in the case where the paper medium value giving system gives a high value to the paper medium on which the amount information is not printed, the value of the paper medium cannot be visually determined by humans. Even a paper medium with a high value can reduce the risk of theft.

The paper medium value assigning system according to the present embodiment executes processing for assigning a virtual currency balance to a paper medium. In this embodiment, as an example of value information, a key for extracting a virtual currency balance given to a paper medium is used.

FIG. 19 shows an example of an outline of the entire process executed in the paper medium value assigning system of the present embodiment. The value assignment system of the present 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 accepts input of image information and value information of a paper medium and a virtual currency balance to be transferred to the paper medium from a delivery person, and sends a balance hold request including the input movement balance to the virtual currency management server Sent 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 to place the transfer balance on hold. The virtual currency management server 500 creates a transfer balance in the hold state, that is, a hold balance withdrawal key for drawing out the hold balance, and transmits it to the management terminal 300. The pending balance withdrawal key includes information indicating the corresponding pending balance. The pending balance can be withdrawn only by the pending balance withdrawal key.

Subsequently, the management terminal 300 transmits the input image information and the received hold balance withdrawal key to the authentication server 100. The authentication server 100 holds the received image information of the paper medium and the held balance withdrawal key in association with each other. Thereby, a movement balance is given to the paper medium.

Note that a system administrator different from the delivery person may input the image information of the paper medium and the balance to be moved to the paper medium to 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 delivery person to the authentication requester. The authentication requester uses the authentication requester terminal 200 to authenticate the received paper medium. The authentication requester terminal 200 receives input of image information of the paper medium subject to authentication request from the authentication requester and transmits it to the authentication server 100.

Specifically, the authentication server 100 searches the image information held by the authentication server 100 for image information that matches the received image information. If the matching image information exists, the authentication server 100 acquires a pending balance withdrawal key corresponding to the image information. The authentication server 100 executes value guarantee processing for 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 a hold balance key to the virtual currency management server 500 in accordance with an instruction from the authentication requester. The virtual currency management server 500 moves the pending balance corresponding to the pending balance movement key to the authentication requester. Specifically, the virtual currency management server 500 is a process for transferring the pending balance to the virtual currency balance of the authentication requester, or for transferring the actual currency amount corresponding to the pending balance to the bank account of the authentication requester. Execute processing to create transfer data.

FIG. 20 shows a configuration example of the virtual currency management server 500. The virtual currency management server 500 is configured by 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 may not be held 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 descriptions of the processor 501, the memory 502, the auxiliary storage device 503, the input / output interface 504, and the communication interface 505 are the same as the descriptions 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 a virtual currency balance management program 511 and a pending balance withdrawal key generation program 512. The virtual currency balance management program 511 executes management processing such as registration, update, and reference of a virtual currency balance stored in a virtual currency balance table 520 described later. The retained balance withdrawal key generation program 512 generates a retained balance withdrawal key.

The auxiliary storage device 503 holds a virtual currency balance table 520. The virtual currency balance table 520 includes the identification information (login ID to the virtual currency management server 500) of the customer who holds the virtual currency, the password corresponding to the identification information, the virtual currency balance of the customer, and the virtual status of the customer in the hold state. A held balance withdrawal key for withdrawing each of the currency balance and the virtual currency balance in the hold state is associated and held.

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

The paper medium registration request program 311 receives the virtual currency balance to be transferred to the paper medium, the login ID to the virtual currency management server 500 of the delivery person, and the input of the password from the delivery person (S2102). The paper medium registration request program 311 transmits a balance hold request including the input transfer 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 balance hold processing (S2104). Specifically, the virtual currency balance management program 511 specifies a combination of a login ID and a 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 balance in the hold state, that is, a hold balance withdrawal key corresponding to the hold balance, links the generated hold balance withdrawal key with the hold balance of the delivery person, Store in the balance table 520. Note that the pending balance withdrawal key generation program 512 creates a pending balance withdrawal key that is different from the pending balance withdrawal key already stored in the virtual currency balance table 520.

In step S2104, when the received combination of identification information and password is not included in the virtual currency balance table 520, or when the transferer's virtual currency balance is less than the received transfer balance, the pending balance withdrawal key generation program 512 An error message is transmitted to the management terminal 300 without generating a pending balance withdrawal key.

Subsequently, the virtual currency balance management program 511 transmits the pending balance withdrawal key to the management terminal 300 (S2105). The paper medium registration request program 311 sends 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 performed the input in S2102, to the authentication server. 100 (S2106).

In step S2102, the paper medium registration request program 311 may further accept an input of an authentication requester ID, a validity period, authentication requester information, delivery person information, and the like from the delivery person. 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 an image feature amount from the paper medium image included in the received paper medium registration request (S2107). Note that the paper medium registration request program 311 may perform feature amount extraction processing 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, stores the issued paper medium ID, the extracted feature amount, and information included in the paper medium registration request in association with each other in the paper medium table 140 (S2108). The value information column 143 stores a balance withdrawal key.

For example, when information on a paper medium having the same or similar feature quantity as the extracted feature quantity 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 two feature amounts is equal to or less than a predetermined threshold, 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. When it is determined 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 holds the pending balance and the pending balance 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 a paper medium registration response even after a predetermined time has elapsed from the processing in step S2105, the virtual currency balance management program 511 assumes that the registration has not been completed, and that the above-described pending balance and pending balance withdrawal key The deletion process may be executed.

FIG. 22 shows an example of authentication processing by the paper medium value assigning system. The processing in steps S1001 to S1012 is the same as that in FIG. The following steps S1002 to S1012 and steps S2213 to S2217 are executed for each paper medium image photographed in step S1001. Hereinafter, processing after steps S1001 to S1012 are completed will be described.

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

Also, 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 in 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. Transmission of the pending balance withdrawal key to the authentication requester terminal 200 by the authentication server 100 is an example of a value guarantee process in the present embodiment.

The paper medium image transmission program 213 updates the authentication status of the paper medium in accordance with the authentication result indicated by the paper medium authentication result notification (S2215). Specifically, for example, when the authentication result is successful, 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 “authenticated (OK)”. When the authentication result is unsuccessful, the authentication status of the paper medium image in the paper medium image storage area 215 is changed to “authenticated (NG)”. Further, when the authentication result is successful, 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 a request from the authentication requester.

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

In addition, when a real currency corresponding to a pending balance is transferred to the authentication requester's bank account or the like, the paper medium image transmission program 213 displays the transfer request account information (bank code, account number, authentication requester's communication) of the authentication requester. The destination account information is received from the authentication requester, and the input bank account information is included in the pending balance transfer request.

When the real currency corresponding to the pending balance is transferred to the authentication requester's bank account or the like, the paper medium image transmission program 213 holds the authentication requester ID to the authentication requester's authentication server 100 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 account information from the transfer account column 137 corresponding to the authentication requester ID in the authentication requester history table 130 and transmits it to the management terminal 300.

Subsequently, the virtual currency balance management program 511 executes a 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. When the transfer data is normally created, the virtual currency balance management program 511 deletes the hold balance key and the hold balance corresponding to the hold 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 elapsed since the transfer data was successfully created, the virtual currency balance management program 511 stores the deleted hold balance key and the hold balance. Undo and delete the transfer data. When the transfer data is not created normally, the virtual currency balance management program 511 transmits 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 received combination of login ID and password exists in the virtual currency balance table 520.

When 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 the pending balance key And the pending balance corresponding to the pending balance key is deleted. When the combination does not exist, the virtual currency balance management program 511 transmits 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 hold balance withdrawal key in the paper medium authentication result notification, and acquires information indicating the hold balance from the hold balance withdrawal key. Information indicating the acquired pending balance may be included in the paper medium authentication result notification.

At this time, in step S2216, 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 it is determined that the authentication server 100 is valid, the authentication server 100 transmits the pending balance withdrawal key corresponding to the paper medium to the virtual currency management server 500, and the process proceeds to step S2217.

When it is determined that the authentication server 100 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 an error message to the authentication requester terminal 200. By such processing, the held balance withdrawal key does not flow out of the authentication server 100, so that the security level can be increased.

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

As described above, the paper medium value assigning system according to the present 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, with the paper medium value assignment system of this embodiment, the delivery person can safely pass the virtual currency balance held by himself / herself to the authentication requester who holds the virtual currency. Transactions are realized.

The paper medium value imparting system of the present embodiment executes a process for imparting a value as a gift certificate to a paper medium. Note that the gift certificate is an example of a paper-type prepaid payment means, and the paper medium value assigning system of the present embodiment can give the value as a paper-type prepaid payment means to any paper medium.

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

First, the management terminal 300 accepts input of image information on a paper medium and a gift certificate amount as value information from a system administrator of a gift certificate issuer from the system administrator, and the input information is authenticated by the authentication server 100. Send to. The authentication server 100 holds the received image information and paper amount information of the paper medium in association with each other. Thereby, 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 delivered from the issuer to the customer. Subsequently, the customer delivers a paper medium to the store staff and purchases a product. The store staff uses the authentication requester terminal 200 to authenticate the received paper medium. 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 the image information held by the authentication server 100 for image information that matches the received image information. If the matching image information exists, the authentication server 100 executes value guarantee processing for acquiring money amount information corresponding to the image information and creating transfer data corresponding to the acquired money 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 corresponding 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, transfer destination account number, and gift certificate amount.

Also, 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 in 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.

Through the processing described above, the paper medium value assigning system of this embodiment assigns value as a gift certificate to any paper medium, accurately executes authentication processing of the paper medium, and creates transfer data to the store can do.

In the present embodiment, the paper medium value assignment system in the client server method is described. However, the paper medium value assignment system may be realized by a P2P method such as a block chain, for example. In this case, for example, each of a plurality of terminals (nodes) installed in each place takes 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 that function as the authentication server 100 and are connected via a network (each of the plurality of terminals plays a part of the function of the authentication server 100), for example, a block chain is formed by the plurality of terminals. The paper medium delivery history may be recorded in a block of the block chain. Thereby, especially when there is a transaction broker between the delivery person and the authentication requester, the distribution process of the paper medium can be more accurately guaranteed. In addition, 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 function of the virtual currency management server 500), The transaction history of virtual currency may be recorded in the block of the block chain.

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

Further, the medium used in the paper medium value assigning 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, in the authentication server 100, an image of a medium such as cloth, stone, or wood and a value associated with the image are registered in advance instead of the paper medium image, and the authentication server 100 receives the received medium. The authentication process and the value guarantee process may be executed for the image. In this case, information indicating physical properties unique to the cloth, stone, wood, etc. (information that does not change by printing or printing, such as a shape pattern) is used as the image feature amount of the cloth, stone, wood, etc.

Hereinafter, 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. What is the paper medium value imparting system according to the present embodiment that adds value to a paper medium and executes authentication. Different philosophy.
