In general, identity verification is the identification and authentication of a user who attempts to access an object in an internal or external network through an information security system. The identification of an identity identifies who the user is. It is a process of notifying, and authentication is a process of confirming whether a user is a legitimate user.

Identification is the basis for other functions required by the intrusion prevention system such as access control, audit record and tracking to be operated based on the identifier of the subject and object. First access control to prevent this.

The authentication mechanism is the most basic element in the identification function. In addition to the general password method, a one-time password, an authentication method using an encryption method, and an authentication method using biometrics are used in various ways.

If you use your ID card to verify your identity, your front social security number and photo will be used. The fingerprint on the back will be used for more accurate identification. Organizations that need security attention now store their fingerprints in a database and use them to restrict access.

An example of identity verification using such a resident registration card is disclosed in Korean Patent Laid-Open Publication No. 2002-0032671 (personal identification system and control method thereof).

The technology disclosed in the above publication relates to an identity verification system, and more specifically, a fingerprint identification system using a resident registration card to verify identity by comparing and analyzing a fingerprint registered in an administrative computer network with a fingerprint in a resident registration card and an actual user's fingerprint and the same. A control method comprising: a fingerprint reader configured to recognize a fingerprint of a user; A scanner which scans an image by scanning a hologram of a resident registration card at a specific angle and scans fingerprints and contents of the resident registration card; A computer for receiving and analyzing input information of the fingerprint reader and the scanner; Disclosed is a personal identification system using a resident registration card and a control method thereof, which includes a verification server for verifying a verification request of the computer and requesting information from an administrative database of an administrative computer network.

In addition, an example of identification verification using a resident registration card is disclosed in Korean Patent Laid-Open Publication No. 2001-0067486 (identification system and method using a database information consisting of a fingerprint of a resident registration card and a fingerprint of a resident registration card and a biometric fingerprint).

The technology disclosed in the above publication is a system that proves the identity of the administrator by using the information built into the database and the biometric fingerprint of each individual by electronically fingerprinting the fingerprint on the ID card and the fingerprint of the ID card. It is a system that judges the identity and error of identity.It is the identity that provides quick and accurate business support in the process of checking the identity when applied to the unmanned automatic civil certificate issuer that proves the identity in issuing various certificates by the administrative agency.

Hereinafter, a conventional identification card identification system currently used in the Ministry of Government Administration and Home Affairs will be described with reference to FIGS. 1 and 2.

1 is a block diagram illustrating an identification card system according to the prior art.

As shown in Fig. 1, reference numeral 101 denotes a personal identification device for confirming that the user is the user, and 102 denotes a personal computer that compares the fingerprint of the administrator database with the fingerprint of the identification device 101. Is a database of the Ministry of Government Administration and Home Affairs that stores personal information.

The identity verification device 101 includes an ID scanner 10 for scanning an ID card, a fingerprint input device 20 for receiving a fingerprint, and a comparison recognition unit 30 for comparing the fingerprint of the scanned ID card with the input fingerprint.

2 is a flowchart illustrating a method of confirming an ID according to the related art.

As shown in Fig. 2, the user inserts an ID into the identity verification device 101 (ST201). The identification card scanner 10 color-scans the front and the back of the ID card at 600 DPI resolution (ST202). Since the resolution of the fingerprint of the registered administration and administration database is 500 DPI, the resolution of the identity verification device 101 was set to 600 DPI in the administration and administration. Next, the user inputs a fingerprint to the fingerprint inputter 20 (ST203). The identity verification device 101 reads the fingerprint of the input identification card and the fingerprint of the fingerprint input device 20 by the comparison recognition unit 30 to determine whether there is a match (ST204). If it does not match, a self-identification and a message are generated (ST208). If there is a match, the process proceeds to the next step. Even when the fingerprint printed on the identification card of another person is erased and the user's fingerprint is printed, the result matches that of the fingerprint input device 20. Of course, it is a forgery, but it is impossible to discriminate by the procedure so far.

Next, the identity verification device 101 characterizes the personal information such as the name, ID number, address, issue date of the front side of the ID card, and then transmits the information read along with the fingerprint to the PC 102 (ST205). The PC 102 downloads the corresponding person's information from the Ministry of Public Administration and Home Affairs Database 103 and determines whether the name, address, issue date, and fingerprint match the information received from the identity verification apparatus 101 (ST206). If the results match, the identity verification is completed (ST207).
