Abstract

PROBLEM TO BE SOLVED: To provide a face photograph reference system which prevents the fraudulent use or forgery of a face photograph from occurring in a passport, an identification card or the like. SOLUTION: In passports or identification cards 1 with face photographs 3, a two-dimensional bar code 2 representing face photograph data is cryptographically processed using magnetically recorded data 4 as a code key. Then the two-dimensional bar code 2 is deciphered through a magnetic bar code reader and the face photograph shown on a screen unit such as a display or the like is compared to the face photograph attached to the passport, the identification card or the like and printed, and then the genuineness of the face photograph is verified.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for verifying an identification card containing a facial photograph or a facial photograph of a passport or the like. About.

[0002]

2. Description of the Related Art In recent years, identification cards and passports with a face photograph have been used in various fields and have become widespread. Such identification cards with a face photograph are generally simply pasted and printed with a face photograph. Therefore, it is possible to easily forge or falsify by using another person's ID card and pasting the face photograph. In particular, forgery and falsification of passports is a major international problem.

[0003]

The problem is that conventional identification cards and passports containing a face photograph can be easily forged or altered by stealing a person's name and replacing the face photograph. was there. Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a face photograph verification system capable of reliably preventing forgery or falsification of a passport containing a face photograph or identification cards.

[0004]

In order to achieve the above object, according to the first aspect of the present invention, face photograph data is displayed as two-dimensional bar code information, the face photograph data is reproduced through a reader, and a passport or identification card is identified. It is characterized in that it is pasted on a book and verified against a printed face photograph. The invention according to claim 2 is characterized in that a two-dimensional bar code for displaying face photograph data forms an image using transparent ink which is difficult to see. According to a third aspect of the present invention, the two-dimensional bar code information for displaying the face photograph data is encrypted using magnetic data or the like as an encryption key.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a face photograph verification system according to the present invention will be described below with reference to the drawings. FIG.
1 is a plan view of a facial photograph verification system to which the present invention is applied. This facial photograph verification system has two-dimensional barcode information 2 for displaying facial photograph data written therein. The facial photograph verification system 1 has a magnetic recording layer 4 and magnetic recording data written in the magnetic recording layer 4. Is used as an encryption key to perform encryption processing on the two-dimensional barcode information 2 displaying face photograph data. It is desirable to use a transparent ink that is difficult for human eyes to see for a two-dimensional barcode that displays face photograph data in order to prevent forgery and alteration. As these transparent inks, stealth barcode inks, DNA inks and the like are used. The face photo data written in the two-dimensional bar code for displaying the face photo data is decrypted using the encryption key written in the magnetic recording data through the bar code reader, and is displayed on the display. It is compared and verified. When the two-dimensional barcode data and the face photograph match, it is determined that the face is authentic. If the verification data does not match, it is determined to be forgery or falsification. FIG. 2 is a block diagram showing a two-dimensional bar code encryption process for displaying face photograph data. A two-dimensional barcode is encrypted based on a predetermined algorithm using magnetic data as an encryption key, and is recorded as two-dimensional barcode data on an identification card or a passport. When displaying the two-dimensional barcode data, an instruction for decryption is issued using the secret key of the issuer, and the encrypted data of the two-dimensional barcode with the face photograph is decrypted and collated with the magnetic data as the encryption key. Is displayed on the display device.

Embodiment 1 FIG. 1 shows a configuration of a passport and an identification card in a facial photograph verification system according to the present invention. Is a base material; Is a two-dimensional barcode; Is a face photo, Indicates a magnetic recording layer.

[0007]

As described above, according to the present invention, face photograph data is displayed as two-dimensional bar code information which has been encrypted using magnetic data or the like as an encryption key, and the face photograph data is reproduced through a reader. , Pasted on a passport or ID card and verified against a printed face photo, so that a passport or ID card that can prevent theft or forgery of a face photo can be obtained. Has an effect.
