Description

Forgery discrimination of residence certificate and person in question identification system and a method

The present invention relates to a forgery forgery identification and identification system of a resident registration card and a method thereof. A system and method thereof are provided.

Conventional technology related to the present invention is a self-identification system described in Korean Laid-Open Patent Publication No. 2002-0032671 (hereinafter referred to as "prior art"). The prior art system compares the fingerprint registered in the administrative vision network with the fingerprint on the ID card and the fingerprint of the actual user to verify the identity, and determines the authenticity of the ID card by determining the image of the hologram on the ID card.

1 is a view showing the entire system of the prior art. As shown in FIG. 1, the prior art system includes a fingerprint reader 10 that recognizes a user's fingerprint, a scanner 20 that scans fingerprints and contents of a hologram of a resident registration card and a resident registration card, the fingerprint reader 10, and a scanner 20. Computer 30 for receiving and analyzing the input information of the server, verifying the verification request of the computer 30, and the authentication server for requesting information to the Ministry of Government Administration (DB) database (hereinafter referred to as "DB") ( 50) and a printer 40 for outputting the information received from the authentication server 50 through the computer 30.

Referring to the operation of the prior art as follows. The ID card is inserted into the scanner 20 to scan the ID card. At this time, scan the resident registration number on the front of the resident registration card, fingerprint information on the back. It also scans the image created by contrasting the hologram at a particular angle. The computer 30 receives the scanned information and analyzes the image information imaged at a specific angle to determine the authenticity of the resident registration card. In the case of forged resident registration card, an error message is output and terminated.

Then, the user's fingerprint is retaken through the fingerprint reader 10, and the collected fingerprint is compared with the fingerprint of the scanned resident registration card to confirm that the user is the first person. In addition, after character recognition of the scanned resident registration number, the resident registration number and the fingerprint information of the scanned resident registration certificate is transmitted to the authentication server 50, the authentication server 50 finds the fingerprint on the administration and government DB 60 using the resident registration number. Secondary identity verification compared to the fingerprint information on the resident registration card. Finally, the computer 30 receives the verification result from the authentication server 50, receives the document name, and outputs a certain type of document to the printer.

Such a conventional technique is to determine the authenticity of the resident registration card by hologram, the present invention has a problem that it is difficult to confirm the forgery fact only by hologram because the forgery technology can be forged without breaking the hologram of the resident registration card.

In addition, the primary identity verification step of the prior art authenticates by comparing the collected fingerprint information and the fingerprint information on the back of the ID card, which is likely to cause an authentication error because the size of both images is different. And, the second identity verification step of the prior art is to compare the fingerprint information on the ID card fingerprint information and the administration and administration DB (60), which is the same size of the image is low probability of authentication error, but if you look at the case of forgery of the ID card The fingerprint on the back is left intact, so the photo on the front is mostly forged.

In addition, in the case of the prior art, the resident registration information on the administration and governor DB 60 is used, which may be difficult to directly link due to the possibility of personal privacy infringement and information leakage.

The technical problem to be achieved by the present invention is to solve the problems of the prior art as described above to verify the forgery and alteration of the resident registration card by comparing the fingerprint image of the resident registration card with each image of the Ministry of Government Administration and Home Affairs DB, the user's face shooting and the user It is to provide a forgery identification and identification system and method for forgery of the resident registration card which can increase the authentication rate by collecting fingerprints and authenticating them with photographic images and fingerprint images of the Ministry of Public Administration and Home Affairs DB.

As shown in FIG. 2, the ID card forgery identification and identity verification system according to an embodiment of the present invention includes a PC camera 100, a fingerprint scanner integrated scanner 200, a terminal computer 300, an authentication server 400, and a cache DB. 500.

Here, the PC camera 100 photographs the user's face, which may be included in the terminal computer 300 or may be mounted outside. The fingerprint reader human body scanner 200 not only scans the photograph, fingerprint and social security number of the resident registration card but also collects the user's fingerprint. That is, the fingerprint reader integrated scanner 200 includes a scanner 220 for scanning a resident registration card and a fingerprint reader 240 for collecting a user's fingerprint as shown in FIG. 3. In addition, the scanner may be separated as a scanner or a fingerprint reader without using the fingerprint reader integrated scanner 200 to scan a resident registration card or to take a fingerprint again. The terminal computer 300 receives and analyzes input information of the fingerprint reader integrated scanner 200. The cache DB 500 stores only the fingerprint feature point information and the photo feature point information extracted from the photo information and the fingerprint information of the administrative unit DB 600 in which the resident registration information is stored. The authentication server 400 authenticates the authentication request of the terminal computer 300. The authentication server 400 performs forgery identification and user authentication using the data transmitted from the terminal computer 300 and the information of the cache DB 500. .

The image information preprocessor 310 performs preprocessing such as binarization, tilt correction, distortion correction, and noise removal on the image of the resident registration card scanned by the scanner 220. The image information area separator 312 separates and extracts the image preprocessed by the image information preprocessor 310 into a resident registration number portion, a photo portion, and a fingerprint portion. The character recognition unit 314 characterizes the resident registration number by character recognition of the resident registration number portion separated by the image information area separation unit 312, and comprises a first face information feature point extractor 316 and a first fingerprint information feature point extractor ( 318 extracts a facial feature point and a fingerprint feature point from the photo portion and the fingerprint portion separated by the image information area separator 312, respectively.

The fingerprint information preprocessor 320 performs preprocessing such as binarization, tilt correction, contrast correction, noise removal, etc. on the fingerprint collected from the fingerprint reader 240 built in the fingerprint reader integrated scanner 200. The second fingerprint information feature point extractor 322 extracts a feature point from the fingerprint information preprocessed by the fingerprint information preprocessor 320.

The face information preprocessor 330 performs preprocessing, such as binarization, vectorization, noise removal, and contrast adjustment, on the user's face image photographed from the PC camera 100. The second face information feature point extractor 332 extracts a feature point from the face information preprocessed by the face information preprocessor 330.

In this case, the method of extracting the feature points of the fingerprint information and the feature points of the face information by the first and second fingerprint information feature point extractor and the first and second face information feature point extractor, respectively, are as follows. As for the feature point of the fingerprint, the image of which the noise is removed from the fingerprint image is made into thin lines using the shape of the fusion and the valley of the fingerprint. Then, the fingerprint feature point data is generated by binarizing the position of the feature point and the direction of each feature point. In addition, in the method of extracting feature points of the face, eyes are first detected from the image from which the noise is removed from the face image as described above, and the size and direction of the face are calculated based on the detected eye position. The size and position of the mouth are calculated, and the fingerprint feature point data is generated by binarizing the distance, the size, and the direction between the elements using the two eyes and the mouth as basic elements to generate the face feature point data.

The first comparison authentication unit 340 may extract the feature point information extracted from the scanned fingerprint image (referring to the image of the fingerprint of the resident registration card) and the collected fingerprint fingerprint image (the image of the user's fingerprint obtained through the fingerprint recognizer 240). The fingerprint is authenticated by comparing and matching the feature point information extracted from the information. In addition, the second comparison authentication unit 350 extracts the feature point information extracted from the scanned face image (referring to the image of the resident registration card) and the captured face image (the user's face is collected through the PC camera 100). Facial feature is authenticated by comparing and matching feature point information extracted from the image.

The data transmitter 360 extracts the extracted feature point information and texts that are output values of the first and second fingerprint information feature point extractors 318 and 322 and the first and second face information feature point extractors 316 and 332.

The authentication server 400 compares various information received from the terminal computer 300 with various data retrieved from the cache DB 500 and performs authentication. At this time, when extracting a variety of data included in the cache DB (500) uses the resident registration number transmitted from the terminal computer (300).

The data receiver 410 receives various data transmitted from the terminal computer 300. The data separator 420 separates the received data into feature point information of the scanned picture, feature point information of the scanned fingerprint, feature point information of the collected fingerprint, and feature point information of the photographed face.

The third comparison authentication unit 430 compares and authenticates the facial feature point information retrieved from the cache DB 500 and the feature point information (referred to the information received from the terminal computer 300) of the received scanned picture using the social security number. . In addition, the fourth comparison authenticator 440 compares and authenticates the feature point information of the fingerprint searched by the cache DB 500 and the feature point information of the received scan fingerprint using the social security number. The fifth comparison authenticator 450 compares and authenticates the feature point information of the face retrieved from the cache DB 500 and the received feature point information by using the resident registration number. The sixth comparison authentication unit 460 compares and authenticates the feature point information of the fingerprint retrieved from the cache DB 500 and the feature point information of the received fingerprint using the social security number.

The result transmitter 470 transmits a result of comparison authentication by the third, fourth, fifth, and sixth comparison authentication units.

In addition, the authentication server 400 further includes a cache DB additional update unit 480 that adds or updates the administrative DB DB 600 to the cache DB 500 when it is added or updated. 6 is a diagram illustrating an internal configuration of the cache DB additional update unit 480.

As illustrated in FIG. 6, the cache DB additional update unit 480 may further include a data addition update monitoring unit 482 for monitoring data when the data of the administrative unit DB 600 is added or updated, and the fingerprint information from the data added or updated.

In this case, as described above, the cache DB additional update unit 480 may be included in the authentication server 400, but may be included in a separate server located outside the authentication server 400. In addition, the cache DB additional update unit 480 may be included in the cache DB 500 in a module form.

A method of adding or updating data of the cache DB 500 by the cache DB addition updating unit 480 will be described with reference to FIG. 6. First, when addition or update of data is detected from the data addition update monitoring unit 482, which constantly monitors the data addition or update status of the administration and government department DB 600, the social security number and data to be added or updated from the administration and administration DB 600. Receive the transmission. At this time, the fingerprint feature point extractor 484 and the face feature point extractor 486 extract the fingerprint feature point and the face feature point from the addition or update data, respectively, and the DB additional update unit 488 caches the feature point information and the social security number. Update to 500.

Hereinafter, the identification and forgery identification method and identification verification method of the resident registration card according to an embodiment of the present invention.

7 is a flow chart showing a forgery registration forgery determination method according to an embodiment of the present invention.

When the user inserts the ID card into the fingerprint reader integrated scanner 200, the ID card is scanned (S100 and S110). At this time, the fingerprint reader integrated scanner 200 scans the fingerprint information on the front and back of the resident registration number and photo.

The scanned information is transmitted to the terminal computer 300, and the image information area separator 312 separates the resident registration number portion, the photo portion, and the fingerprint portion from the entire image (S120).

Next, the first facial information feature point extractor 316 and the first fingerprint information feature point extractor 318 extract the photo feature point information and the fingerprint feature point information from the separated photo image and the fingerprint image, respectively (S130). In addition, the character recognition unit extracts the resident registration number through the character recognition from the image of the resident registration number (S130).

The terminal computer 300 encrypts the extracted facial feature point information, fingerprint feature point information, and social security number using a public key-based encryption method and transmits it to the authentication server 400 (S140).

The authentication server 400 decrypts the encrypted information transmitted from the terminal computer 300 by using a decryption key, and searches face feature point information and fingerprint feature point information on the cache DB 500 using the social security number as a search key. (S150).

In addition, the authentication server 400 performs comparison authentication with the facial feature point information and the fingerprint feature point information extracted from the cache DB 400, respectively, from the photo feature point information and the fingerprint feature point information transmitted from the terminal computer 300 (S160). Such comparison authentication is performed through the third and fourth comparison authentication units 430 and 440 included in the authentication server 400 as described above.

At this time, if the authentication of the feature point information of the face and fingerprint, respectively, if either of the authentication fails, it is determined that the ID card is forged (S170). In addition, the authentication server 400 transmits the forgery determination result of step S170 to the terminal computer 300 (S180).

8 is a flowchart illustrating a method of verifying identity according to an embodiment of the present invention.

The fingerprint reader 240 is included in the fingerprint scanner integrated scanner 200 to collect the user's fingerprint, and photographs the user's face through the PC camera (100) (S210).

The collected user fingerprint image and the captured user face image are subjected to preprocessing such as noise removal, binarization, thinning, etc. by the fingerprint information preprocessor 320 and the face information preprocessor 330, respectively. In addition, the second fingerprint information feature point extractor 322 and the second face information feature point extractor 332 extract fingerprint feature point information and face feature point information from the preprocessed image, respectively (S220).

Next, the fingerprint feature point information and the photo feature point information on the resident registration card extracted in step S130 of FIG. 7 are compared with the fingerprint feature point information and face feature point information extracted in step S220, respectively (S230). This is compared and authenticated by the first and second comparison authentication units included in the terminal computer 300 as described above, respectively. Here, it is determined primarily whether the person (S240).

In addition, the terminal computer 300 transmits the fingerprint feature point information, the face feature point information (which refers to the information extracted from the fingerprint and the photographed face image) and the resident registration number to the authentication server 400 extracted in step S220. (S250).

The authentication server 400 compares and authenticates the fingerprint feature point information and the face feature point information transmitted from the terminal computer 300 with the fingerprint feature point information and the face feature point information retrieved from the cache DB 500 (S260). At this time, the authentication server 400 searches the cache DB 500 using the resident registration number transmitted from the terminal computer 300. As described above, the comparison authentication process is performed by the fifth and sixth comparison units 450 and 460 included in the authentication server 400. This comparative certification process is to determine whether the second person (S270).

Next, the authentication server 400 transmits the identity verification result to the terminal computer 300 (S280). In addition, the terminal computer 300 outputs the identification result of the identity transmitted from the authentication server 400 and the determination result of the resident registration card transmitted from the authentication server 400 in step S180 (S290 and S300).

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.

As described above, according to the present invention, forgery of the resident registration card can be discriminated by comparing not only the fingerprint image of the resident registration card but also the photographic image to identify the forgery of the resident registration card.

In addition, in verifying the identity, not only fingerprint authentication but also photo authentication may be combined to improve a user's identity verification rate. That is, in the case of fingerprints, 7% to 8% of all users have dry fingerprints, which drastically decreases the recognition rate, and 3% to 5% of fingerprint images collected by swiping a finger at the time of issuance of a resident registration card exist. It also lowers the recognition rate. However, since the present invention performs a combination of fingerprint authentication as well as photo authentication, the identity verification authentication rate can be dramatically improved.

In addition, it is possible to prevent personal information leakage and privacy by using the cache DB made by extracting only the characteristic points of fingerprint and photo information from the administration and administration DB without using the resident registration related information of the administration and administration DB.
