Description

Variable seal type seal system, seal check system, seal check method and seal check program

The invention relates to a seal anti-counterfeiting technology, in particular to a seal having an excellent anti-counterfeiting effect and a seal collation system using the seal.

In our country, personal identification is often confirmed through daily seals in daily life. Although many personal identification systems that use human information such as fingerprints or retina have recently been proposed, the identification of personal identity through seals will remain the primary method of personal authentication in the future.

In recent years, with the popularity of computers, the identification of personal identity through a seal can also be accomplished by displaying the seal information previously registered on the display and checking against the checked seal. For example, Patent Document 1 discloses a seal collating apparatus that can accurately discriminate between the seal stamp and the collated seal from the seal pattern without being affected by the adhesion of the ink pad or the seal spot.

Patent Document 1 Japanese Patent Laid-Open Publication No. 2004-326821

However, there is a problem that it is easy to forge a seal by means of a seal to confirm an individual's identity. Although there are anti-counterfeiting methods such as a seal certificate, there is still the possibility of forging or obtaining a seal certificate through an improper method, which affects the correctness of identity verification. However, the above-mentioned seal checking device cannot solve the disadvantage of the existence of the seal.

In addition, for electronic signature systems that can be signed or stamped on electronic documents, although measures to prevent falsification of materials or forgery of stamp materials have been taken, the method of confirming personal identity through seals is in principle carried out by means of written stamping. Therefore, the anti-counterfeiting measures of the electronic seal system cannot be directly used.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and its main object is to provide a variable seal seal capable of effective anti-counterfeiting for a stamp attached to paper. It is also an object of the present invention to provide a security check system that uses this variable stamp seal.

In order to achieve the above object, the variable seal seal of the present invention has the following features: an original seal memory means for storing the seal data; and an authentication means for performing the certification of the stamper; and the outdated authentication by the aforementioned authentication means A stamp change means for maintaining the seal material of the original seal memory means according to a specific regularity; and a stamp output means for outputting the changed seal data.

With this configuration, the stamper is authenticated at the time of stamping, and the original stamp is changed according to a certain rule to generate a changed stamp. Therefore, the stamp is different each time the stamp is printed, thereby realizing the prevention of forgery of the seal. Variable seal seal.

The variable seal type seal further includes a stamping count counting means for recording the number of times of the variable stamp type stamping, wherein the stamp deforming means can change the stamp data held by the original stamp memory means according to the number of stamping times; Further, the variable seal seal may further include a timing means for authenticating the recording authentication means, and the seal deforming means may change the seal data held by the original seal remembering means based on the timing.

In this way, a changed stamp can be generated based on the number of stamps and the stamp date.

Further, the signature verification system according to the present invention includes a server that holds the stamp data for verification, and a client terminal that is connected to the server to communicate and acquire the stamp data from the server for display; The feature is: the aforementioned seal verification system is further provided with a variable seal seal; the variable seal seal has the following means: maintaining the original seal memory means of the seal data, and the authentication means for performing the stamper's certification, and the aforementioned certification a stamp change means for changing the seal information of the original seal memory means according to a specific regularity, and a stamp output means for outputting the changed seal data and displaying the aforementioned specific regular character string; The client terminal includes: an input means for receiving input of the character string; and a communication means for transmitting a character string input by the input means to the server; and the server includes: receiving the client terminal The above-mentioned textual list of means of receiving, and storage and retention in the aforementioned original The servo original seal storage means of the seal material of the seal memory means, and the servo which changes the seal data stored in the servo original seal storage means according to the character string displayed by the above-mentioned received character string. The stamp changing means and the information transmitting means for transmitting to the client terminal by using the servo stamp changing means and the changed stamp data.

With this configuration, the same modification as the modified form of the stamp for the variable seal type stamp is registered on the server side of the confirmation stamp, and when the seal is checked, the check stamp image is generated based on the same regularity. Even if the seal is forged, it is almost impossible to match the seal pattern for the check, thereby realizing a seal verification system with a high safety factor.

Of course, the present invention can not only implement the signature verification system through the above method, but also implement the signature verification method by using the special functions of the devices constituting the signature verification system, or implement the steps through the computer. Such a program can be distributed via a recording medium such as a CD-ROM or a communication medium such as the Internet.

As described above, the variable seal type stamp according to the present invention can prevent the forgery of the seal since the stamp is changed every time the stamp is applied.

In addition, it can be stamped only after the stamper's identity verification, so it is possible to prevent others other than the person who is registered as the legal holder of the seal from stamping.

Moreover, for the signature verification system related to the present invention, since the modification form of the stamp used in the variable seal seal is registered on the authentication server, the verification can be performed according to the same rule at the time of identity verification. With the seal pattern, for the forged seal, the possibility of the two patterns being identical is almost zero, thereby realizing a highly secure seal check system.

Therefore, the stamp forgery can be effectively prevented by the present invention, and the practical value of the seal as a main method for personal identification authentication is very high.

Embodiments of the present invention will be described below with reference to the drawings.

The fingerprint information storage unit 22 also corresponds to the memory device 16 shown in FIG. 1, and is realized by a memory device such as a ROM, and stores fingerprint information of the stamper.

The fingerprint reading unit 23 is realized by the fingerprint sensor 17a shown in FIG. 1. The main function is to read the fingerprint of the stamper and output the fingerprint information to the stamper authentication unit 24.

The stamper authentication unit 24 corresponds to the fingerprint authentication device 17 shown in FIG. 1, and acquires fingerprint information from the fingerprint reading unit 23, and checks the fingerprint information stored in the fingerprint information storage unit 22 to determine whether the input fingerprint is legally stamped. The fingerprint of the person. When the stamper authentication unit 24 determines that it is a legal stamper, the variable seal stamp is allowed to be stamped, and the command signal is transmitted to the stamp deforming unit 25, the stamp count counting unit 26, and the timer unit 27, respectively.

The number-of-prints counting unit 26 is realized by the counter 14 shown in FIG. 1, and is a processing portion for recording the number of times the variable stamp type seal 1 is stamped. When the number-of-prints counting unit 26 receives the command signal from the stamper authentication unit 24, the number of times of stamping is increased, and is outputted to the stamp deforming unit 25 and the stamping unit 28 as a part of the specific character string.

The timer unit 27 corresponds to the timer 13 shown in FIG. 1, and receives the command signal from the stamper authentication unit 24, and outputs the date (certification date or stamp date) as a part of the specific character string to the stamp deformation. Part 25 and stamping portion 28.

The stamp deforming unit 25 is realized by a ROM that stores a program for deforming a stamp based on a predetermined rule, a CPU that executes the program, and the like, and corresponds to the substrate 12 shown in FIG. 1 .

After receiving the command signal from the stamper authentication unit 24, the stamp deforming unit 25 reads the original stamp image data of the stamper from the original stamp storage unit 21, deforms the stamp data, and outputs the stamp data to the stamping unit 28. The specific regularity refers to the stylization of the change shape and the change position of the seal in advance based on the number of times of stamping recorded by the number-of-prints counting unit 26 and the date of registration recorded by the timer unit 27.

In the first embodiment of the present invention, the number of times of stamping recorded by the stamping count unit 26 and the date of registration recorded by the timer unit 27 are output to the stamp deforming unit 25 as a part of the specific character string, so that the number of stamps and the date of authentication are As a specific character string, the change shape and position of the seal are determined according to this specific character string.

The stamping portion 28 corresponds to the stamping device 19 shown in Fig. 1, and the stamp material deformed by the stamp deforming portion 25 is output as a stamp by the conventional ink jet printing principle. Further, the stamping unit 28 outputs the number of times of stamping obtained from the number-of-prints counting unit 26 and the date of authentication obtained from the timer unit 27 as a specific character string, together with the stamp. The trigger for outputting the stamp can be confirmed by the sensor whether the stamping surface 19a as shown in FIG. 1 is placed on the object (paper) to be stamped. Further, the switch for controlling the output of the stamp may be disposed outside the stamp frame 10, or may be disposed such that the stamp surface 19a protruding from the stamp frame 10 is placed on the article to be stamped, and is caused to enter the stamp frame 10 Internally, once the stamping surface 19a enters the interior of the stamp housing 10, the switch outputs a stamp. . The ink used here is preferably the same color as the ink.

In addition, it is also possible to use a dot print structure instead of an ink jet printing structure.

As described above, after the variable seal type seal 1 according to the first embodiment of the present invention is used, the stamp cannot be printed without being authenticated by the stamper. Therefore, it is possible to prevent the legal holder of the variable seal seal 1 from being used. Others stamped.

In addition, each time the stamp is printed, the number of stampings and the stamping date are output together with the deformed stamp, so that the anti-counterfeiting can be easily performed.

The timer of the first embodiment of the present invention preferably uses a radio wave timer. The use of a radio timer prevents tampering with the date and improves safety.

(Second embodiment)

Next, as a second embodiment of the present invention, a seal collation system using the variable seal type seal 1 according to the first embodiment will be described.

Fig. 3 is an explanatory diagram of use of the seal collation system according to the second embodiment of the present invention.

The main body of the seal collation system according to the second embodiment of the present invention is an unidentified majority of the authenticated person (stamp) who is the user of the variable seal seal 1 and is authorized by the authenticatee to manufacture the variable seal seal 1 The seal maker and the certification application filed by the document 20 stamped by the certified person using the variable seal seal 1 provide an unspecified number of certifiers (for example, a financial institution such as a bank) based on the certification result.

The certified person provides the seal maker with personal information such as the name required to make the seal, and commissions the variable seal seal 1 to provide the information required to verify the stamp.

The seal maker inputs the personal information and the verification information in the seal manufacturing device 30, and manufactures the client, that is, the variable seal seal 1 of the authenticated person. When the variable seal type seal 1 is manufactured, the seal manufacturing apparatus 30 registers the authenticated person ID (stamper ID) unique to the person to be authenticated to the variable seal type seal 1, and at the same time as the certified person ID and the manufactured seal. An association is established between them and registered to the connected authentication server 40 that is communicable with the seal manufacturing apparatus 30. Further, the seal manufacturing apparatus 30 associates the stamper ID with the program related to the stamp change stored on the internal ROM of the variable stamp seal 1 and registers it with the verification server 40. The stamper ID registered on the variable stamp type seal 1 will constitute a specific character string together with the number of stamping times and the stamping date, and will be output together with the stamp when the variable stamp type stamp 1 is stamped.

When the authenticated person performs the authentication application by using the document 20 stamped by the variable seal seal 1, the authenticator inputs the seal and the specific character string on the stamped document 20 to the authenticator terminal 50, and goes to the verification server 40. Request to send the seal information for verification. The verification server 40 and the authenticator terminal 50 are connected through the network 100, and when the verification server 40 receives the seal information request including the specific character string, the seal information of the verification object is retrieved by using the specific character string as a key, and is sent to the The authenticator terminal 50. The authenticator verifies the identity verification of the authenticated person by visually checking the check seal displayed on the display device of the authenticator terminal 50 and the seal on the stamped document 20.

Here, although the method in which the authenticated person provides the information required for the certification to the seal maker is adopted, it is also possible to adopt a method in which the authenticated person inputs the information (such as a fingerprint) required for the authentication when the variable seal seal is started.

4 is a block diagram showing a functional configuration of each device constituting the seal collation system according to the second embodiment of the present invention. Since the schematic diagram of the variable seal seal 1 has been given in Fig. 2, its illustration is omitted in the figure.

The seal manufacturing apparatus 30 is a device for manufacturing the variable stamp type seal 1, and as shown in FIG. 4, includes an information input unit 31, a seal generating unit 32, and a communication unit 33.

The verification server 40 is a device for providing the seal data required for the verification of the seal based on the request of the authenticator terminal 50, and includes the authenticated person DB 41 and the communication unit 42 and the seal retrieval unit 43.

The authenticator terminal 50 is a client terminal device such as an ATM (Automatic Teller Machine) that requests the authentication server 40 to check the image data of the stamp, and includes an input unit 51, a communication unit 52, and a display unit 53.

The information input unit 31 is an input device such as a keyboard or a mouse that inputs personal information of the authenticated person or information required for authentication.

The seal generating unit 32 is a processor that generates the original stamp image data of the variable stamp type seal 1 based on the information input from the information input unit 31. The seal generation unit 32 executes a program for generating a seal based on the family name, first name, last name, or name of the authenticated person input by the information input unit 31, and designs the original seal to generate image data of the original seal.

Further, the seal generating unit 32 assigns the authenticated person ID (printer ID) unique to the authenticatee, and inputs it to the communication unit 33 in association with the image data of the original stamp. When the stamper ID is assigned, the stamp generating unit 32 may request the verification server 40 via the communication unit 33 to confirm whether or not the duplicate stamper ID is registered.

Moreover, the seal generating unit 32 generates a unique stamp deformation form for each authenticated person according to a certain rule.

The seal manufacturing apparatus 30 stores the image data of the original stamp generated by the stamp generating unit 32 in the original stamp storage unit 21 of the variable stamp seal 1 and the modified form of the stamp generated by the stamp generating unit 32 in the form of a program. The step of inputting the stamp deforming portion 25 of the variable stamp type seal 1 completes the manufacture of the variable stamp type seal 1.

The communication unit 33 is an interface for communicating with the authentication server 40, and mainly functions as the name and name of the authenticated person input through the information input unit 31, the image data of the original seal generated by the seal generating unit 32, and the stamper ID. And a variant of the stamp is sent to the verification server 40.

The authenticated person DB 41 is a database that stores information related to the authenticated person. Figure 5 shows an example of the data composition of the authenticated DB. As shown in FIG. 5, the authenticated person DB 41 records information such as the stamper ID, the name of the authenticatee, the image data of the original seal of the authenticatee, and the program of changing the stamp, according to different IDs.

The communication unit 42 is a connection interface established by communication with the seal manufacturing apparatus 30 and the authenticator terminal 50, and receives the name of the authenticated person and the image data of the original seal from the seal manufacturing apparatus 30, and stores it in the authenticated DB 41. The authenticator terminal 50 receives the seal information request and outputs it to the seal search unit 43.

The seal search unit 43 is a processor that searches the authenticated person DB 41 and generates a check stamp based on the seal information request received by the communication unit 42. The seal search unit 43 derives a modified form of the image data of the original seal and the original seal image data from the specific character string included in the seal information request, and the transformed seal pattern is generated as a check seal, and the seal information is transmitted through the communication unit 42. It is sent to the authenticator terminal 50.

The input unit 51 is an input device such as a keyboard or a mouse that the authenticator inputs a specific character string in the stamped document 20 that has been stamped.

The communication unit 52 is a interface connected to the verification server 40, and transmits a seal information request including a specific character string input through the input unit 51 to the verification server 40, and receives the seal information from the verification server 40, and outputs the seal information to the display unit. 53.

The display unit 53 is a display device such as a CRT display that displays the seal information received by the communication unit 52 and outputs a check seal. Needless to say, the display unit 53 may be omitted, and the configuration for printing the check stamp may be used instead.

Next, a modification of the original seal generated by the seal generating unit 32 will be described.

First, the seal generating unit 32 divides the generated image data of the original stamp into a plurality of modules, and assigns a serial number (module No.) to each module. The module segmentation method and the module number (module No.) allocation method can be divided into square or rectangular modules as shown in FIG. 6(a), and the serial numbers are sequentially assigned from the predetermined modules. As shown in Fig. 6(b), in the image data of the original seal, only the printing portion is divided into irregular modules and the module serial number can be randomly assigned.

Next, the seal generating unit 32 determines whether or not to change each of the module numbers based on the specific regularity, and changes the shape to a shape if the change is made, thereby generating a modified form of the original stamp. Then, the seal generating unit 32 programmatically sets the generated deformation form in the stamp deforming unit 25 of the variable seal type seal 1 and transmits it to the verification server 40 via the communication unit 33.

Fig. 7 is a diagram showing an example of a modified structure of the original seal registered by the authenticator DB41. In the figure, the case where the number of times of stamping is used as a predetermined deformation principle is taken as an example, and when the number of times of stamping is "1", a deformation form (YT001) in which the module "A1" is added and inverted to "A10" is used. .

FIG. 8 is a schematic diagram showing an example of changes to the original seal image data module.

For the variation of the above-mentioned plus points, for example, the internal portion of the printed portion of the pre-deformation module 200 may be removed to become the module 201; or the same color point may be added to the lower portion of the printed portion to become the module 202; The edge of the part is added to the point where the color inversion is reversed and becomes the module 203 or the like.

In addition, the printed portion of the pre-deformation module 200 may be a checkered pattern to form the module 211; or the vertical stripe shape may be the module 212; or the horizontal stripe shape may be the module 213.

In addition, it is also possible to reverse the printing portion of the pre-deformation module 200 into an inversion change of the module 221, or to change the printing portion to the trimming of the module 231, and to use the pre-deformation module. The enclosing of the module 200 becomes a change in the enclosing of the module 241 or the module 242.

Next, a procedure for manufacturing the variable seal type seal 1 by the seal manufacturing apparatus 30 will be described with reference to FIG.

Figure 9 is a flow chart showing the manufacturing sequence of the variable seal seal.

First, the seal manufacturing apparatus 30 receives the information of the manufacturer of the variable seal seal 1 by the information input unit 31, that is, the information input by the authenticated person (seal) (S102), and then passes through the seal generation unit 32, based on the input. The content is assigned a stamper ID (S104).

Then, the seal manufacturing device 30 generates the image data of the original stamp, that is, the stamp image, based on the input stamper information content through the stamp generating unit 32 (S106). The generated stamp image is divided into a plurality of modules (S108); a serial number is assigned to each module (S110). The module division and the module number assignment method have been described above, and the description is omitted here.

Next, the seal manufacturing device 30 generates a deformed version of the original stamp through the signature generating portion 32 (S112); logs the image and the deformed form of the original stamp to the variable stamp seal 1, and simultaneously transmits it to the verification server 40 through the communication portion 33. And registered to the authenticated person DB 41 (S114).

Finally, the seal manufacturing apparatus 30 inputs the fingerprint information of the stamper in the variable seal seal 1 to verify whether or not the stamp can be performed (S116), thereby completing the production step. Of course, the production step can also be ended in step S114, and the step S116 is left until the stamper makes an input at the start of use.

Next, an operation mode of the variable seal type seal 1 manufactured in the above-described order will be described with reference to FIG.

First, the variable seal type seal 1 reads the fingerprint of the stamper in the fingerprint reading unit 23, and performs authentication by the stamper authentication unit 24 (S202). The stamper authentication unit 24 checks the input fingerprint and the fingerprint information stored in the fingerprint information storage unit 22, and confirms that it is a legal stamper (Yes in S204); the stamp count counting unit 26 increases the number of stamps and The obtained numerical value is output to the seal deforming portion 25 and the stamp portion 28 as a part of the specific character string. The timer unit 27 also outputs the authentication date as a part of the specific character string to the stamp deforming unit 25 and the stamping unit 28, and the stamp deforming unit 25 generates a specific character string from the numerical value of the number of stamping times and the authentication date (S206).

The seal deforming unit 25 determines which module of the original seal image is to be changed based on the generated specific character string, and determines the module that gives the difference (S208).

Finally, the selected stamp image is outputted through the stamping portion 28, and the specific character string and the stamper ID are output together (S210), and the entire steps are completed.

When the authenticator receives the document 20 stamped in the above sequence, the authenticator can check the seal with the authenticator terminal 50. Next, the working sequence of the seal collation system when the seal is checked will be described with reference to FIG.

FIG. 11 is a sequence diagram showing communication between the authenticator terminal 50 and the authentication server 40 when the stamp is checked.

First, the authenticator terminal 50 receives the authenticator name and the authentication person-related information such as the authentication destination input by the authenticator via the input unit 51 (S302), and transmits the input authenticator information to the verification server 40 via the communication unit 52 (S304).

Upon receiving the authenticator information, the verification server 40 confirms whether the authenticator is a trusted authenticator (S402); and returns the confirmation result to the authenticator terminal 50 (S404). As described above, the identity of the authenticator is confirmed by the authentication server before the check is started to prevent the improper use of the seal. As for the identity verification of the authenticator, the authenticator information database can be established on the verification server 40 in advance, and the judgment can be made by whether or not the authenticator is registered in the database.

When the authenticator terminal 50 receives the positive certifier identity confirmation result, the display unit 53 displays a screen requesting input of the stamper's name, the stamper ID, the specific character string, and the like, and receives the input of the information through the input unit 51 (S306). ). Figure 12 shows an example of this input screen. After the stamper name, the stamper ID, the specific character string, and the like are input, the authenticator terminal 50 transmits the input information to the verification server 40 as a stamp information request (S308). According to the screen example given in Fig. 12, after the stamper's name and code (specific character string) are input, pressing the send key, the authenticator terminal 50 sends the stamp information request to the verification server 40.

After receiving the seal information request, the verification server 40 searches the image data of the original seal from the authenticated person DB 41 with the ID of the authenticated person as a key (S406), and simultaneously reads the original seal image. A variant of the data. Then, the verification server 40 will perform a change corresponding to the specific character string included in the seal information request according to the read deformation form, and generate a check seal image (S408); and generate the seal map. The image is sent to the authenticator terminal 50 (S410).

The authenticator terminal 50 outputs the received seal image to the display unit 53 (S310), and completes the communication sequence. Figure 13 shows an example of this picture. In the example of the screen shown in FIG. 13, the received check stamp image and the number of changes added to the stamp image are displayed, and the authenticator can judge the yes stamp on the stamp image and the stamped document 20 by the naked eye. It is not the stamp of the stamper himself.

Of course, there may be a third party who sees the seal image displayed on this screen, knows the position and number of changes, and forges the seal image. In view of this possibility, at least one of the stamp images generated by the verification server 40 can be arbitrarily changed. Even if a virtual change is inserted, the authenticator holding the real seal (the seal stamped in the stamped file 20) can completely determine which part is a virtual change, and does not hinder the check step, but can obtain a better anti-counterfeiting effect. .

In addition, the verification server 40 can save the record of the specific character string received the query, and control the stamp information request containing the same specific character string so as not to generate the check seal image. Through this kind of control, the same seal cannot be repeatedly authenticated, so that the seal verification system with good anti-counterfeiting effect can be realized. Of course, it is not a limitation on multiple certifications of the same seal, if flexible measures of multiple certifications can be allowed for a certain period of time (for example, one day).

Of course, as described above, when the verification is performed by the verification server 40, the following manner can also be adopted.

Upon receiving the stamp information request, the verification server 40 transmits the requested original seal image to the authenticator terminal 50. The original seal image is set so that each module is selectable, and the authenticator can refer to the stamp on the stamped document, and display the display unit 53 from the authenticator terminal by using an input device (input portion 51) such as a mouse. The module of the seal image is selected from the changed modules.

The authenticator terminal 50 transmits the seal image selected by the module to the verification server 40, and the verification server 40 collates the transmitted seal image and the collation seal image.

The seal collation system according to the second embodiment of the present invention may have the configuration shown in FIG.

As shown in Fig. 14, the verification server 60 is provided with a collating unit 64 in addition to the above configuration, and the authenticator terminal 70 is provided with a stamp reading unit 74 in addition to the above configuration.

The collating unit 64 is a processor that collates the image data of the stamp received from the authenticator terminal 70 and the image data of the collation stamp generated by the seal search unit 63 by a calculation method such as image matching, and transmits the collation result. The communication unit 62 transmits to the authenticator terminal 70.

The seal reading unit 74 is a member that reads a stamp on the stamped document 20 and performs digital image formation, and can be realized by a device such as a scanner.

The communication sequence when the seal collation is performed between the authenticator terminal 70 and the verification server 60 of the above configuration is as shown in FIG.

As shown in the figure, the authenticator terminal 70 reads the stamp on the stamp file 20 through the stamp reading unit 74 when accepting the input of the stamper ID and the specific character string (S502); the map of the stamp to be read It is sent to the verification server 60 together with the stamper ID and the specific character string (S504).

Further, the verification server 60 collates the received seal image with the collation stamp generated by the seal search unit 63 via the collation unit 64, and transmits the collation result to the authenticator terminal 70 (S604).

The authenticator terminal 70 outputs the received collation result to the display unit 73 for display (S506), and completes the communication sequence.

Further, the seal collation system according to the second embodiment of the present invention may have a configuration as shown in FIG.

As shown in FIG. 16, the authentication server 80 has the configuration of the signature registration device 30 at the same time, and the authenticator terminal 90 has the collating portion 95.

The communication sequence when the seal collation is performed between the authenticator terminal 90 and the verification server 80 of the above configuration is as shown in FIG.

As shown in the figure, until the verification server 80 transmits the verification stamp image to the authenticator terminal 90, it is the same as the communication sequence shown in FIG.

Thereafter, after the authenticator terminal 90 receives the stamp image from the verification server 80 (may also be before receiving), the stamp reading unit 94 reads the stamp on the stamp file 20 (S702); the reading unit 95 reads the image. The image of the taken stamp and the received stamp image are collated (S704); and the collation result is output to the display unit 93 for display (S706).

Through the above structure, the seal verification system is composed, and the verification operation can be automated, and the verification person is no longer required to check through the naked eye.

The seal collation system according to the second embodiment of the present invention may have a configuration as shown in FIG.

The verification server 60a in the signature verification system shown in Fig. 18 has a collating portion 64a, which is different from the signature collating system shown in Fig. 4. Further, the communication unit 62a included in the authentication server 60a communicates with the communication unit 52 of the authenticator terminal 50, which is different from the verification server 60 shown in FIG.

The communication sequence when the seal collation is performed between the authenticator terminal 50 and the verification server 60a having the above configuration is as shown in FIG.

As shown in the figure, the stage until the authenticator terminal 50 accepts the stamper ID and the specific character string input is the same as the communication sequence shown in FIG.

Thereafter, the authenticator terminal 50 outputs a screen requesting the designated portion (module) of the stamp to be displayed to the authenticator via the display unit 53, and receives an input of the designated change portion from the authenticator via the input unit 51 (S802). . Upon receiving the input of the changed portion, the authenticator terminal 50 transmits the stamper ID, the specific character string, and the changed portion to the verification server 60a (S804).

Thereafter, as shown in FIG. 11, the verification server 60a retrieves the image data of the original stamp (S406), and changes it according to the modified form to generate a seal stamp image (S408). Next, the verification server 60a passes the verification unit 64a, and checks the changed portion received by the communication unit 62a and the changed portion of the generated seal image (S902), and transmits the verification result to the authenticator terminal 50 (S904).

Finally, the authenticator terminal 50 outputs the received collation result to the display unit 53 for output (S906).

Through the seal verification system of the above structure, the certifier only needs to specify the changed part to complete the check, thereby simplifying the operation at the time of check.

As described above, in the seal collating system according to the second embodiment of the present invention, the modified version of the variable stamp seal is simultaneously registered on the verification server, and the verification is performed by using a specific character string as a keyword for verification. The seal image, so even if it is checked against the forged seal, the possibility of agreement is almost zero, so that the seal verification system with high safety performance can be realized.

In addition, by using a specific character string to limit multiple authentications of the same seal, security performance can be further improved.

(deformation example)

Next, a modified example of the variable seal type seal according to the first embodiment will be described.

Fig. 20 is a schematic structural view showing a modified example of the variable seal type seal.

The variable stamp type seal 300 according to the modified example can be changed in the stamp pattern 1 each time the stamp is printed, which is the same as the variable stamp type seal 1 according to the first embodiment. However, it has a card-like outer shape and does not include a stamping device and an ink supply device, which is different from the variable stamp type seal 1 according to the first embodiment described above.

Further, the variable seal type seal 300 has a mode changeover switch 310, a display unit 318, and a material registration output terminal 319, which is different from the variable seal type seal 1 according to the first embodiment.

Hereinafter, the description will be centered on these differences.

The stamp frame 301 has a card shape, and includes a mode switch 310, a fingerprint sensor 317a, and a display unit 318 on one surface (surface) thereof.

The mode changeover switch 310 is a switch for switching the on/off state of the variable seal seal 300 power supply and the variable seal seal 300 operation mode (to be described later). This mode changeover switch 310 can also use a push button switch in addition to the slide switch as shown. Of course, the position at which the mode changeover switch 310 is disposed is not limited to the surface of the stamp frame 301, and may be the back side or the side surface.

The display device 318 is a display device such as a liquid crystal display that displays a changed stamp image or a user interface that displays an operation mode of the variable stamp seal 300. This display unit 318 preferably also uses a touch panel type input operation interface, but a button for input operation may be additionally provided on the stamp housing 310. Of course, the stamp displayed by the display device 318 may be identical to the stamp stamped by the stamping device 19 or the like, or may be displayed in a different color. For example, the stamp of the cover of the stamping device 19 or the like may be red or red, and the stamp displayed by the display device 318 may be black. Further, the display device 318 can display only the module combination, the module that changes when the stamp is printed, the character string, and the like as a simple display.

The data registration output terminal 319 is an interface terminal for data connection (input/output) with other external devices. As the interface, for example, USB or IEEE1394 can be used. Here, the other external device refers to a device (seal stamping device) or an authenticator terminal which is composed of the ink supply device 18 and the stamping device 19 of the variable seal type seal 1 of the above-described first embodiment.

Figure 21 is a block diagram showing the functional composition of a variable stamp seal 300 relating to a modified example.

As shown in FIG. 21, the variable seal type seal 300 has a seal material output unit 328, a display unit 329, and a registration information changing unit 330 as functional components, which is different from the variable seal type seal 1.

The stamp data output unit 328 is a stamp data that has been changed by the stamp deforming unit 325, and a specific character composed of the number of stamps obtained from the stamp count counting unit 326, the date of certification obtained from the timer unit 327, and the stamper ID. The column or the like is output to the processor of the external device or display unit 329.

The display unit 329 corresponds to the display device 318 shown in FIG. 20 for displaying and outputting the stamp data and the like acquired from the stamp data output unit 328.

The login information changing unit 330 is a processor that changes or deletes the information stored in the fingerprint information storage unit 322 or registers new information in the fingerprint information storage unit 322. After confirming that the user is a legitimate user by the stamper authentication unit 324, the login information changing unit 330 changes the information registered in the fingerprint information storage unit 322 according to the user's operation through the input operation interface.

The stamper authentication unit 324 is similar to the stamper authentication unit 24 of the first embodiment, and is configured to determine whether the fingerprint information input by the fingerprint reading unit 323 is a fingerprint of a legal stamper, and is set according to the mode switching switch 310. The operation mode of the variable seal seal 300 activates the seal deforming unit 325 or activates the login information changing unit 330.

Here, the operation mode of the variable seal seal 300 will be described. The working mode includes, for example, a stamping mode or a login information change mode.

The stamping mode refers to a mode in which stamp data is output from the stamp data output unit 328 to the display unit 329 or the stamping device, and operates in the order described in the first embodiment.

The login information change mode refers to a mode in which the activation registration information changing unit 330 changes the information stored in the fingerprint information storage unit 322. By setting the login information change mode, you can get the following convenient performance.

By additionally recording the fingerprint information of the stamper in the fingerprint information storage unit 322, identity authentication can be performed even if some parts of the fingerprint information of the stamper cannot be used due to an injury or the like. Here, the information stored in the fingerprint information storage unit 322 may be a fingerprint of a different finger, or may be a combination of a fingerprint and other human body information such as a retina or a vein image.

In addition, the fingerprint information of the plurality of stampers may be additionally recorded in the fingerprint information storage unit 322. For example, after the fingerprint information of the printer of the stamper is registered, the fingerprint may be stamped by the agent. When logging in to the agent's fingerprint information, the sender's identity verification is first performed through the variable seal seal 300, and then the fingerprint information of the agent is input within a certain period of time. This is to avoid unrestricted agent fingerprint information login to ensure security. When the fingerprint is registered as an agent, the fingerprint information storage unit 322 can record by attaching a banner or the like to identify the fingerprint information of the agent. Further, when the agent is allowed to perform the stamping, the signature matching system described in the second embodiment may register the agent-related information in the authenticated DB of the authentication server. Since the agent related information is also registered on the verification server, different stamp change patterns can be applied to the stamper and the agent. When the stamper authentication unit 324 performs the agent identification, the stamp data output unit 328 adds an agent mark such as (generation) to the stamp material to indicate that the agent stamps.

In addition, since the fingerprint information of a plurality of stampers can be additionally recorded in the fingerprint information storage unit 322, it is possible to set not only the stamping without multi-person authentication, but also to prove who the stamp is obtained (including many A chapter covered by the recognition of the case of the person's consent. This function is especially important, for example, if the stamp is a corporate seal such as a company.

For the case where the fingerprint information storage unit 322 records the fingerprint information of a plurality of stampers, FIG. 22 shows an example of the data structure held by the fingerprint information storage unit 322.

As shown in FIG. 22, the fingerprint information storage unit 322 records a stamper ID assigned according to an individual or a multi-person combination, a name or a name combination corresponding to each stamper ID, and a different correspondence corresponding to each stamper ID. The stamp is deformed. In the case of such a data structure, when a person or a plurality of people use different variants in combination, it is necessary to store the same information in the authenticated DB of the seal verification system described in the second embodiment.

According to an example of the fingerprint information storage unit 322 shown in FIG. 22, when a company seal is stamped, a stamp example displayed by the display device 318 of the variable seal seal 300 is shown in FIG.

The stamp example 341 is a stamp having only the stamper ID "KOH001-A" shown in Fig. 22. According to the seal collation system described in the second embodiment, the authenticator can input the specific character string displayed under the company stamp to the authenticator terminal, request verification from the authentication server, and log in according to the authenticated DB of the authentication server. The information was learned to be a certified stamper (Ichiro Yamada).

Further, the seal examples 342 and 343 are stamps having only the stamper ID "KOH001-B" or "KOH001-C" shown in Fig. 22, and the seal collation system described in the second embodiment can also be obtained by the authenticator. It is a certified stamper (Suzuki Erlang or Tanaka Saburo).

The seal examples 344 and 345 are stamps stamped with the stamper ID "KOH001-AB" or "KOH001-ABC" shown in Fig. 22. The seal collation system described in the second embodiment described above can also be known by the authenticator. The combination of the certified stamper (the combination of Yamada Ichiro and Suzuki Erlang or the combination of Yamada Ichiro and Suzuki Erlang and Tanaka Saburo).

In the case where the fingerprint information storage unit 322 stores a plurality of stamper fingerprint information as described above, different operation permission rights may be set for each of the stamper IDs, and the settings may be stored in the fingerprint information storage unit 322. According to this configuration, it is possible to set whether or not to change the information held by the fingerprint information storage unit for different positions in the company, or to set the priority order of the stamping rights.

In addition, a plurality of original stamp materials may be saved in the original stamp image storage portion 321 , and the association between the stamper ID and the original stamp data may be saved in the fingerprint information storage unit 322, so that after the user passes the fingerprint verification, You can choose the stamp you stamped.

Heretofore, various embodiments and variant examples of the variable seal seal and the seal collation system according to the present invention have been described, but the present invention is not limited thereto, and may be in the inventive concept without departing from the scope of the present invention. Perform a variety of deformations or corrections under the guidance.

For example, in each of the above embodiments, fingerprint authentication is used for the stamper identity verification, but a method of password verification or verification using other human body information may be employed. In this case, the fingerprint reading unit 23 shown in FIG. 2 can be replaced with a password input receiving portion that accepts a password input or a human body information reading portion that acquires human body information such as a retina, and the fingerprint information storage unit 22 is replaced with a password storage unit. The password memory part or the body information memory part that stores human body information.

Further, in the second embodiment, the seal search unit derives the image data of the original seal and the modified form of the original seal image data based on the specific character string included in the seal information request, and generates the changed seal image as Check the seal image, but you can also save the change pattern of the seal image in the certifier DB. According to the specific character string included in the seal information request, it is analyzed which stamp form the seal of the stamper is. Make changes and extract the seal image for the check.

Further, in the above-described modified example, the card-shaped variable seal type seal has been described, but the structure of the variable seal type stamp related to the above-described modified example may be mounted on a mobile phone, a PDA (Personal Digital Assistants), or the like. Portable terminal.
