With the above configuration, the following effects can be obtained.
Conventionally, there is a biometric authentication method that uses fingerprint information, face information, etc. for authentication when performing personal authentication. Since spoofing is difficult with biometric authentication, security can be improved as compared with an authentication method using key input or the like.

However, when the biometric authentication method of Patent Document 1 is used, it is necessary to centrally manage the biometric authentication on the server and collate the input biometric information with the biometric information on the server, which is managed in order to introduce the authentication system. There was a problem that it took a lot of time and cost to build a server and an authentication network.
Further, in the techniques of Patent Document 1, since the biometric information is held in the server, there is a security risk that the biometric information is leaked when the server is hacked or the like.

On the other hand, the information processing apparatus according to the embodiment of the present invention has a feature point extraction unit 100 that extracts the feature point information 210 from the biological information 200 and a feature point information 210 that is extracted by the feature point extraction unit 100. , A feature point image conversion unit 110 that encodes and converts the image data 220 into optically recognizable image data 220, a print control unit 120 that prints the image data 220 converted by the feature point image conversion unit 110 on the card 6, and print control.

In addition, since the biometric information 200 is not stored in the host device 1, it is possible to prevent leakage of the biometric information 200 due to hacking of the host device 1 and reduce the security risk.

Further, conventionally, there has been a method of storing biological information in an IC card. When biometric information is stored in an IC card, there is a problem that it costs a lot to purchase an IC card for introducing the system.

That is, the server or the like required for a normal biometric authentication system is no longer required.

[Other Embodiments]

With this configuration, the biometric authentication system Y can be used as an entry / exit management system or the like. Furthermore, security can be enhanced by performing card creation and biometric authentication on separate devices.

In the above-described embodiment, the front camera 3b of the image acquisition device 3 is described so as to capture a user's face image and a two-dimensional bar code of the card 6.
However, the front camera 3b of the image acquisition device 3 acquires only the user's face image, and the image scanner 3a of the image acquisition device 3 captures the two-dimensional bar code of the card 6 and acquires it as image data 221. It is also possible to do. At this time, it is also possible to use a dedicated two-dimensional bar code reader for imaging the two-dimensional bar code.
Further, it is also possible to take a photograph of the user's face printed on the card 6 and acquire it as biometric information 201. In this case, the photograph of the passport or the like written on the card 6 and the two-dimensional bar code may be simultaneously acquired as biometric information 201 and image data 221 for authentication.
With this configuration, the image acquisition device 3 can support a flexible configuration. In addition, the face photograph printed on the card 6 can be configured to compare the face image of the user captured by the front camera 3b for additional authentication, further improving security.

Further, in the above-described embodiment, it is described that an image is taken from the front camera 3b of the image acquisition device 3 and a two-dimensional bar code in which the feature points of the face image are encoded is generated. However, as the image acquisition device 3, a Web camera or the like may be separately connected for shooting.
In addition, in the above-described embodiment, the face image and the card 6 are described so as to be captured separately, but the front camera 3b of the image acquisition device 3 or the like simultaneously captures the face image of the user. It is also possible. In this case, the biological information acquisition unit 140 recognizes the face image from the image data 221 and stores the information of the face feature points read from the face image in the storage unit 11 as temporary data used for recognition. It can also be configured.
With such a configuration, the image acquisition device 3 can be configured only by using a general image scanner 3a, a Web camera, or the like, and the cost can be reduced.

In the above-described embodiment, an example in which a face image is used as biological information 200 and 201 has been described. However, as described above, as the biological information 200 and 201, fingerprint images, finger or palm vein images, iris images, voices, motion images, and other various kinds of biological information may be used.
For example, in the case of a fingerprint, a vein image of a finger or palm, an iris image, or the like, a two-dimensional bar code in which the feature points of these data are encoded may be generated. In addition, in these cases, a scanner such as a dedicated fingerprint, a vein of a finger or palm, an iris, etc. for acquiring these biological information 200, 201 may be provided. Further, in the case of a motion image, it is also possible to use moving image data such as a surveillance camera. In addition, in the case of voice, it is possible to analyze and use voiceprint information or the like acquired from the microphone.
With this configuration, various biometric information 200 and 201 can be supported.

In the above-described embodiment, an example in which a QR code (registered trademark) is used as an example of a two-dimensional bar code as image data 220 and 221 that can be encoded and optically recognized is described, but other two-dimensional ones such as PDF417 are described. It may be a barcode. In addition to this, one-dimensional barcode, dot encoding, etc. may be used instead of two-dimensional.
With this configuration, information on the feature points of the biological information 200 can be recorded in the image data 220 and 221 that can be printed on the card 6 by various methods, and can be optically recognized.

In the above-described embodiment, an example of storing a biological image as temporary data in the storage unit 11 has been described.
However, the feature point information 210 or the like in which the biometric information 200 is encrypted may be stored at the time of creating the card 6, the biometric authentication or the like, and used for the re-authentication or the like.
With such a configuration, the waiting time and processing time for biometric authentication can be reduced, and the cost can be reduced.

Needless to say, the configuration and operation of the above-described embodiment are examples, and can be appropriately modified and executed without departing from the spirit of the present invention.
