Description

The technique for issue the passport on the digital condition and the technique for verify the immigration passport, this is the apply to the digital image matching technique.}

The present invention relates to a passport issuance and immigration management system required when traveling abroad for the purpose of travel or business, and more particularly, to an immigration passport examination applying passport issuance and digital image matching technology under digital conditions. to be.

A foreigner who wants to leave the country will apply for a passport to the Ministry of Foreign Affairs and Trade in order to obtain a passport. (1) The current passport issuing system is authorized by the Ministry of Foreign Affairs and Trade at the ward office or provincial office. (2) If there is no problem, the unit issuing department will produce a passport (3) and issue it (4) .At the same time, a copy of the passport application (5) will be made. In the form of inputting to the passport computer system 6 of the Ministry of Foreign Affairs and Trade and reporting the contents to the Ministry of Foreign Affairs and Trade.

In addition, the immigration office will examine the identities of the immigrants (12) with the passport presented by the immigrant (11). In this case, the passport number and personal information of the immigration passport will be inquired in the passport computer system database of the Ministry of Foreign Affairs. By checking and verifying the issuance record of the personal information, and confirming the entry and exit of the passport after confirming the photo of the passport and the real person of the passport (13).

Under the current passport issuance system and immigration office system, there is a problem of forgery and alteration such as changing the photograph of the passport, altering the details of personal information, peeling off the security film with heating or solvent, or altering the details of the visa column. It is always on the rise, and among them, photo-modification is frequently performed, which is difficult even if the holder of the passport is different from the actual picture if the picture on the passport and the actual holder is the same.

Therefore, for the sake of national management, the passport itself can be printed and bound with high-tech technology. When filling out the contents of the passport, the entry field can be printed directly by thermal transfer or ribbon ink jet, etc. After reprinting (ghost image), it is developed with the technique of laminating with a special thin film on it to prevent forgery and tampering attempts.However, even if the passport manufacturing technique is developed with the best technology, The technology of the passport is also developed as a technology of the production of the passport, so that it is more difficult to identify forgery and alteration.

The present invention digitally image the photos presented together with the passport application form as well as the items issued when issuing a passport to solve the above problems, input and store them in the passport computer system of the Ministry of Foreign Affairs and Trade and display the display (Display Previewer) in the immigration office After display on the screen, the identity screening and passport issuance is inquired, and the photograph on the passport and the photograph at the time of issuance from the Ministry of Foreign Affairs and Trade are compared to the triplet and triplet. Even if it is wrong, it reads whether or not it is the same person by using image matching technique, and thus it is possible to thoroughly distinguish forgery and forgery. According to the attached drawings, the details of the issuer of the resident registration card are given. Build a database to store and input images The upper part is equipped with a passport computer database 20, and has a memory unit 21 for digitizing and storing an image of a photograph presented by a passport applicant, and also stores the data stored in the memory unit 21 in the immigration office. And a transmitter 22 and a receiver 23 capable of transmitting and receiving to and from the station 30, and the immigration office 30 is also provided with a transmitter 32 and a receiver 31. A memory for storing a value of the digital camera 33, comprising a keyword (calling tool) 35, a display previewer display 37, and a digital camera 33 capable of photographing an actual person's immigration. Part 34 is also included, and image matching can be used to read whether the picture on the real and the passport is the same person even if the object is deteriorated or the face is deformed a few years after the issue of passport. hing) The reader 36 is constructed to constitute the present invention.

On the other hand, when the passport issuing and immigration office from the immigration office to verify the passport system according to the present invention, when the passport applicants apply for a passport, the Ministry of Foreign Affairs and Trade search the data of the passport applicant stored in the Ministry of Government Administration and Home Affairs database The photographic image 41 on the autonomous database and the photographic image 42 presented by the passport applicant are driven by the normalization search engine E to process the normalized image tubes 43 and 44, respectively, and then the residual images The difference image tube 45 value is obtained, and this is again compared and searched (46), authenticated according to the criteria of matching 47, non-matching (48), and precision search (49), and a passport is issued (50). The Ministry of Trade processes the photographs presented by the passport applicants who have passed the screening of the passport applicants by digital camera or scanning and processes them by transcription or direct printing method. The memory unit 21 of the case 20 is also stored together with the personal information.

In addition, the immigration office 30 inputs the passport number presented by the immigrant using the keyword 35 to display the immigration control information and registered screen image information from the passport computer database 20 of the Ministry of Foreign Affairs and Trade. Display Previewer) Automatically calls to the display 37, firstly confirms whether the passport photo presented by the immigration and the photo at the time of passport application on the automatically called terminal frame are visually confirmed and secondly, the Ministry of Foreign Affairs and Trade Image data of the immigrant automatically called from the database 20 and real-time direct shooting with the digital camera 33 in the immigration office 30 (digital camera at the current inspection point position in order to keep the distance to the subject and lighting constant) (33) automatically retrieves the real-time inspection target area of the face and the image is monitored by the terminal) Ita a visually compared with the passport application photos shown on the screen at the time of the query (Display Previewer) display (37).

And visual comparison of the digital scaned image of the passport photograph and the real digital camera image 52 is performed as a result of the computer matching of the real digital camera image 52 and the photographic image 51 at the time of passport application. The basic skeleton of the image and biometric matching is the basic contour and size, facial features, the position and size of the eyes, the shape of the ears, the appearance and size of the forehead, the shape of the eyebrows, the shape of the lips, the nose The normalization algorithm calculates the normalized correlation value of the face by using the density pattern as calculation data when searching by the normalization search engine (E), and the image data on the passport computer system of the Ministry of Foreign Affairs and Trade. Frame 1 (58), Frame 2 (59) values, Register frame 1 (60), The value of register frame 2 (61) is obtained, and the values are again obtained by OR logic (62) (63), and the remaining difference between the two values and the image data on the passport computer system of the Ministry of Foreign Affairs and Trade and the actual digital camera image of the immigration office. The result of comparison of the image tube is transmitted to the AND logic 64 to obtain the final digital image matching result, and the appropriate judgment 65 is performed.

As described above, the present invention digitalizes the photographs presented together with the passport application form as well as the descriptions when issuing the passport, inputs and stores them in the passport computerization system of the Ministry of Foreign Affairs and Trade, and displays them on the Display Previewer display at the immigration office.
