By doing so, the seal management of the seal can be sufficiently performed, and improper seal seal can be prevented.

[0005]

However, there are some problems in the conventional electronic seal stamp, and the main ones are listed below.

[0006] First, there is a possibility that the approver himself forgets the password or intentionally maliciously maliciously reads and steals the password by a third party.

Second, an object is a seal in which password information is added to bitmap data.
For this reason, imitation electronic seal stamps can be performed by copying and pasting in the same document by another person.

An object of the present invention is to solve the above-mentioned problems, and to provide a method of verifying an electronic seal stamp which is robust against imitation and has high reliability for personal identification.

[0009]

In order to achieve the above object, a method for collating an electronic seal stamp according to the present invention includes a login step of accessing a fingerprint from a user terminal to an authentication server, and a fingerprint collation by an authentication server in advance. A personal authentication process executed by collating with registered fingerprint authentication information, a seal registration requesting process for requesting a seal registration from the user terminal to the authentication server after performing fingerprint matching, and an individual registered in the personal authentication process The authentication server adds the fingerprint authentication information as personal identification information to the seal requested to be registered, and registers the personal identification information in the seal register. It is characterized in that it is registered in.

In the above-mentioned seal registration, the seal imprint data created in advance as bitmap data is registered in an authentication server during an authenticated login session, and the fingerprint authentication information is added to the registered seal imprint data. The document approval procedure is realized from the specified terminal device, and the document approval procedure is performed when the personal identity registered in the login process and the personal authentication process is confirmed. It is preferable to receive the payment and to make a seal on a predetermined document.

Further, with the execution of the above-mentioned stamping on the predetermined document, the stamping information including the ID for identifying the document, the stamping time, the stamper ID, etc. is transmitted to the authentication server, registered, and registered. In the storage of the document in which the seal is performed on the document in the user terminal, if the seal is the seal imprint of the seal registered in the seal stamp register, the normal storage is executed, and if the seal is rejected, the normal seal is performed. It is good practice not to save.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a method for verifying an electronic seal stamp according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 to FIG. 3 show an embodiment of a method for collating an electronic seal stamp according to the present invention.

In this embodiment, a collation system applied to a method for collating an electronic seal stamp authenticated by fingerprint collation is configured by connecting a user terminal 1 and an authentication server 2 to each other. In this configuration, each of a seal registration method (first embodiment) in FIG. 1, a seal method (second embodiment) in FIG. 2, and a seal identification method (third embodiment) in FIG. The procedure example will be described in detail below.

(First Embodiment) FIG. 1 is a processing procedure diagram showing a procedure example 1 of a method for collating an electronic seal stamp between a user terminal 1 and an authentication server 2. In the first example of the procedure, an example of a procedure for registering a seal is shown. The login by fingerprint collation from the user terminal 1 in step S1 is performed by using the fingerprint of the user registered in advance in the authentication server 2 and personal authentication (step S1).
3) is executed. In addition, the user terminal 1 transmits a seal registration (step S2) request to the authentication server together with login (step S1) by fingerprint collation.

In the authentication server 2, personal identification information is added to the seal and registered in the seal register. In this seal registration, seal imprint data created in advance as bitmap data is
Register with the authentication server 2 during the authenticated login session period. As a result, it is regarded as the same person who logged in to the authentication server 2 (step S1) (step S1).
3), personal identification information authenticated by fingerprint collation is added to the seal and registered in the seal register (S4).

According to the seal imprint registration method shown in FIG. 1, the user logs in to the authentication server 2 by fingerprint collation, and when the user is authenticated, adds personal identification information to the seal of the user registered in the authentication server 2 after the login. Then, the seal is registered in the seal register (step S2). In this way, the authentication server 2 is defined as a unique seal of the logged-in user.

(Second Embodiment) FIG. 2 is a processing procedure diagram showing a procedure example 2 of a method for collating an electronic seal stamp between the user terminal 1 and the authentication server 2. In the procedure example 2, a sealing method will be described. In the stamping method of FIG. 2, login is performed by the user terminal 1 by fingerprint collation (step S1).

The user who has received the personal authentication by this login (step S20) sends a seal request (step S110) to the authentication server 2 to seal the document 11 (step S110).
Do for

The authentication server 2 performs personal authentication (step S2).
0) is compared with the seal (step S21), and the seal is paid out to the user terminal 1 (step S22).

Seal data is paid out from the authentication server 2 (step S111), and the paid-out seal data is affixed to the document 11 to be stamped 12. The authenticated seal is stored when the document is stored (step S1).
2).

The stamping information including the stamped document ID, the stamping time, and the login ID of the stamper is sent from the user terminal 1 to the authentication server 2 (step S112). The authentication server 2 collects this information as a log (step S2).
3).

(Third Embodiment) FIG. 3 is a processing procedure diagram showing a procedure example 3 of a method for collating an electronic seal stamp between the user terminal 1 and the authentication server 2. In the third procedure example, a method of confirming the identity of the seal will be described. In the method of confirming the identity of the seal shown in FIG. 3, personal authentication (step S4) is performed by logging in from the user terminal 1 by fingerprint collation (step S30).
0).

The user who has received the personal authentication (step S40) receives the seal imprint a (31
1) is copied and pasted to another place in the document, and the seal imprint b (31)
2) Attempt to obtain approval for additional items in the document such as revisions. In this case, verification of the seal imprint b (312) is performed (step S320), and the authentication server 2 verifies the seal stamp (step S4).
When the document is saved (S32) in 1), it is denied (step S42). This denial information is returned to the user (step S321).

The object of the seal imprint b (312) denied by the access of the document storage (step S32) is not stored as a part of the document data when the document is stored (step S33). As a result, the imprint of the approver cannot be illegally copied and pasted.

Thus, according to the present embodiment, the seal is personally authenticated by the authentication server by fingerprint authentication. For this reason, a seal can be used as a means for personal identification of creation and approval of a document carried between server terminals connected to a network connected to the authentication server.

The above embodiment according to the present invention has the following features. First, based on the user authentication information obtained by fingerprint collation from the user terminal, the user authentication information is given to the electronic seal stamp used by the user. This makes it possible to identify the owner of the electronic seal stamp in the same document, and to assure that the seal imprinted on the document is unique to the user authenticated by fingerprint collation.

Second, once the electronic seal stamp has been authenticated by fingerprint authentication, the personal identification information is held in the electronic seal stamp even if fingerprint authentication is not performed for each seal while logging in to the network. I have.

Third, when the same imprint is imprinted on a plurality of places in the same document such as a revision history, a user other than the subject is intentionally added by adding the authentication information and the authentication time of the user's fingerprint authentication to each imprint. Even if the electronic seal imprint is copied and pasted, it is possible to check that the electronic seal imprint has been illegally copied and pasted.

Fourth, fingerprint collation is applied to personal identification by applying the characteristics of fingerprints, which are unique and life-long, to personal identification. The authentication information obtained by fingerprint collation is highly accurate. Can be inherited. This allows for approval of the evidence,
An electronic seal stamp that has been personally identified with high precision can be easily applied without making a significant change in the flow of documents using a conventional seal such as approval of a request for approval and approval of an in-house document.

The above embodiment is an example of a preferred embodiment of the present invention. However, it is not limited to this.
Various modifications can be made without departing from the spirit of the present invention.

[0031]

As is evident from the above description, in the electronic seal verification method of the present invention, login by fingerprint verification is performed by accessing the authentication server from the user terminal, and fingerprint verification is performed by using the fingerprint registered in advance in the authentication server. This is executed by checking with authentication information. After executing the fingerprint collation, the user terminal requests a seal registration from the authentication server, and when the registered personal identity is confirmed, the authentication server provides the seal requested for the seal registration with the fingerprint authentication information as personal identification information. The registration is added to the seal register, and the personally-identified seal image data is registered in the seal register.

The first effect obtained as described above is that high identification accuracy can be obtained because personal identification by fingerprint authentication is used. The second effect is that since the seal is used in the document flow, the document layout that has been carried around on paper can be used as it is.
