Description

Identity identification system using matrix code and its method {SYSTEM AND METHOD FOR QUOTING AN IDENTIFICATION CARD USING OF A MATRIX CODE}

The present invention relates to an identity authentication system using a matrix code and a method thereof, and in detail, the identification information and the image information are encoded in a matrix code and printed on various identification cards, and when identification is required later, The present invention relates to an identity authentication system and a method using a matrix code, which compares information decoded after scanning of a matrix code so as to search for tampering.

As is well known, due to the recent development of information and communication technology, the development of information providing technology that provides real-time information to various subscribers through at least one host server through a remote data communication network is actively underway.

Based on this, in recent years, information selection technology and compression technology are being developed to more easily access peripheral technologies such as cache memory expansion technology to provide accurate information to subscribers more quickly and subscribers' tastes and preferences. It is also accelerating the development of various contents and its solutions.

The development of electronic communication technology is based on digital technology, which is revolutionizing printing technology. In general, various identification cards to show identity, such as passports, national IDs, driver's licenses, etc. are produced and managed nationally to indicate the identity of the person concerned, so that they cannot be tampered with.

In other words, the use of special patterns, special coated paper, and special paper is used to produce ID cards that cannot be forged or tampered with.

However, even in advanced countries such as the United States, where advanced technology has been developed, such counterfeiting and tampering has a problem that its prevention is not original. In other words, as the development of technology for manufacturing identification cards using special patterns, special coding papers, and special paper develops, the forgery and alteration technology also develops.

In particular, unlike the ID card used in the country, in the case of passport, there is a difficulty in constructing a database of personal information of other people, and even if the database of other countries is opened and shared, there is a problem in real-time translation. Therefore, there has been a problem that forgery and tampering of passports are easier.

The fundamental reason for this problem is that when verifying all IDs, the verifier must check them with the naked eye, and when using a device for ID verification, most of the identification information must be accessed in real time to a remote server built as a database. It takes a lot of time for it, and the device cost is increased.

The present invention has been made in view of the above-described state of the art. The present invention encodes personal information and image information into matrix codes and prints them on various identification cards. It is an object of the present invention to provide an identity authentication system using a matrix code and a method thereof, by which information of the original ID can be retrieved by comparing the decoded information.

Another object of the present invention is to encode and decode the matrix code published in the ID card, so that it is possible to accurately determine whether the ID card is modified or modified without the use of special coding, special patterns, and special paper. The purpose of the present invention is to provide an identification system and a method thereof.

Another object of the present invention is to encode the original content of the identification card in a matrix code and intervene in the identification card, and when the identification is confirmed, the original content is encoded in a matrix code and compared with the matrix code embedded in the identification card to determine whether the forgery is altered. The purpose of the present invention is to provide an identity authentication system and a method using a matrix code that can be automatically verified instead of the naked eye.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail with reference to drawings.

1 is a schematic diagram showing a schematic configuration of an identity authentication system using a matrix code according to an embodiment of the present invention.

Referring to this, an identity authentication system using a matrix code according to an embodiment of the present invention encodes identification information and image information into a matrix code and prints them on various identification cards. In addition, by comparing the decoded information of the matrix code after scanning, it is possible to search the contents of the original ID and its modulation.

That is, the identity authentication system using the matrix code according to an embodiment of the present invention converts the original content including the photo of the identification card into a matrix code, and then prints the matrix code under the identification card to complete the identification card. Then, by scanning the corresponding ID card and comparing the decoded data of the matrix code with respect to the original content, it is possible to determine whether the ID card has been tampered with. Above, the modulation may be determined by the naked eye or may be automatically determined by using the terminal.

Even if the ID card is a passport, it does not need to be an online system because it does not manage identity authentication by establishing a separate database of other people's personal information, and it does not need to be an online system. It has the advantage of being fast, and it is impossible to forgery before breaking the matrix code algorithm. At this time, since the matrix code algorithm is executed in conjunction with the digital signature, the digital signature algorithm can also be broken for forgery.

To this end, in the identity authentication system using the matrix code according to an embodiment of the present invention, identification information is printed and image data (10a) and image data (entered in various identification cards 10 used for identification authentication offline) are printed. An encoding terminal A1 is provided which encodes 10b) into matrix code 18 and controls it to be printed at the bottom of the identification card.

The encoding terminal A1 is provided with a key input unit for inputting the contents of the identification card, and inputs the identification card contents and the image data therein and outputs them on the screen. An identification card processor for editing the size and the like; A matrix code generation processor is configured to generate the matrix code by encoding the identification card content and the image data into a matrix code.

In this case, the encoding terminal A1 is connected to the printer P to be created and edited, and the data and the ID contents of which the ID contents are converted into a matrix can be simultaneously printed on the ID.

Although the configuration of the matrix code will be described in detail with reference to FIG. 3, unlike the general barcode, the matrix code generation processor compresses the document or image data and rearranges and encodes the compressed data to effectively reduce the overall size thereof. As a code, thousands of character data, image data, and color data can be represented in the matrix code.

In addition, the identity authentication system using the matrix code according to an embodiment of the present invention scans the matrix code 18 printed on the bottom of the identification card 10 by the scanner (S), and the decoding data ( It is applied to the inside of A2). Inside the decoding terminal A2, a decoding processor is built in which the matrix code 18 is decoded and converted into original identification card contents and identification data which is image data.

2 is a diagram schematically illustrating a data conversion state through an identity authentication system using a matrix code according to an embodiment of the present invention.

Referring to this, the identification card 10 created through the identification authentication system using the matrix code according to an embodiment of the present invention is the identification card itself, and can perform identification verification, the contents of the identification card posted on the identification card 10. The data 10a and the image data 10b can be encoded with the matrix code 18 and placed at the bottom of the ID card. On the contrary, the content code 10a and the image data 10b of the ID card are decoded by decoding the matrix code 18. Can be restored.

3 is a diagram illustrating a configuration of a matrix code applied to an identity authentication system using a matrix code according to an embodiment of the present invention.

Referring to this, the matrix code 18 according to the present invention is encoded and compressed through a matrix code generation algorithm that encodes the content of the original ID card and the photographic data to suit the form of the matrix data.

That is, the matrix code 18 may be obtained by dividing the read data into a predetermined block unit through a buffer and converting the data format of the unit block into a matrix code form. The matrix code 18 includes an identifier 22 having a rectangular shape, and a plurality of pieces of data are represented by a matrix code in the form of dots 20 between the identifiers 22. Data conversion to the matrix code 18 is subjected to an encoding process that is encrypted by a mathematical algorithm.

On the other hand, the matrix code 18 is configured so that error recovery can be performed based on the identifier of the matrix code 18, and the restoration rate and the error correction rate are set in advance when the matrix code 18 is generated.

The matrix code 18 according to the present invention has a structure and a function different from that of a conventional barcode and a data matrix, and a conventional barcode has a very narrow storage capacity, and a data matrix has been developed to overcome this problem. Even in the case of the matrix, when inputting ASCII data, only 1558 characters can be used, and only 16 matrices can be used. In practice, however, only 700 or fewer characters are stored in the data matrix due to the limitation of the decoding. In other words, the storage capacity per unit area (1 square centimeter) is 249 characters.

However, the matrix code 18 according to the present invention can store a large amount of data through a data compression algorithm and a matrix code generation algorithm, and can process ASCII and binary data, and on average, 24.4 Kbytes per unit area. Has storage capacity.

Therefore, when the image data and the text data described in the identification card are input to the encoding terminal A1, and the encoding algorithm 130 is executed, the contents of the identification card are created by the image data and the text data and the matrix code 18 is executed. The contents of the ID are encoded and generated and the matrix code 18 is placed at the bottom of the ID.

As described above, when identification is required in the state of carrying the produced ID 10, the ID is scanned by the scanner S added to the existing decoding terminal A2. At this time, the scanner S Scanners with normal scanning capacities are sufficient.

The decoding algorithm 140 is built in the decoding terminal A2, and the decoding algorithm 140 is an algorithm for converting the matrix code into the original identification data. At this time, the data scanned through the scanner (S) is the original data (10a, 10b) and the matrix code 18 of the identification card, in the case of the matrix code 18 is decoded by the decoding algorithm 140 and another identification card Original data 10a 'and 10b' are generated. Therefore, by comparing the original data generated by the decoding of the matrix code 18 and the scanned original data with the naked eye or equipment, it is possible to confirm whether the ID card is forged or modified.

The function and operation of the identity authentication system using the matrix code according to the embodiment of the present invention having the above-described configuration will be described in detail with reference to the accompanying drawings.

8 is a flowchart illustrating an ID data encoding process of an ID authentication system using a matrix code according to an embodiment of the present invention.

First, the identification card authentication system using the matrix code according to an embodiment of the present invention key-operates the encoding terminal A1 to input identification card contents, input image data to a file, and identify the position of identification card contents according to a predetermined format. And set the font or color, and set the position of the image data (first step: ST-1) (second step: ST-2) (third step: ST-3).

When the input and editing of ID contents are completed through the above process, the author manipulates the key operation unit of the encoding terminal A1 to convert the ID data into a bitmap (BMP), compresses the converted bitmap into a matrix code. As it encodes, encoding is a kind of encryption. In detail, the compressed bitmap is first divided into a predetermined block unit through a buffer and stored, and the data format of the unit block can be obtained by converting the data format into a matrix code. . The matrix code allows a plurality of data to be expressed as a matrix code in the form of dots based on the identifier of the rectangular shape. The data conversion to the matrix code is an encoding process encrypted through a mathematical algorithm (steps 4a and 4b: ST-4a and 4b).

When encoding of the identification card is completed, the restoration value is set, and the error correction value is set. In this case, the restoration value may be set at the time of production of the initial matrix code generation algorithm, or may be individually set according to the restoration request rate.When encoding is completed, the original ID data and the matrix code encoded with the ID data are printed on ID paper. The ID card is printed out (step 5: ST-5).

9A and 9B are flowcharts illustrating an ID decoding process and a forgery / falsification determination process of an identity authentication system using a matrix code according to an embodiment of the present invention.

In this case, FIG. 9A illustrates a flowchart for performing identity verification through a process of visually comparing or automatically comparing images of respective ID cards restored through an identity authentication system using a matrix code according to an embodiment of the present invention, and FIG. 9B. Is a flowchart showing a process of determining forgery and forgery of identification by converting the scanned identification card image into a matrix code and comparing each matrix code with the matrix code posted on the identification card intact.

First, referring to FIG. 9A, an ID card including a matrix code is scanned using a scanner S to input a matrix code and its contents into the decoding terminal A2 (step 10: ST-10).

The scanned data is input to the decoding terminal A2, and the data is performed to perform an image preprocessing process (11th step: ST-11). In the image preprocessing process, unlike the output image, the dot constituting the matrix code is different from the output image, so that the image filtering process performs image filtering to clearly recognize the dot (step 11a: ST-11a), and the dot After recognition, a process of reconstructing the image is performed (step 11b: ST-11b).

When the image reconstruction is completed, the corresponding image is decoded (Twelfth Step: ST-12), and the data decoding first detects a rectangular identifier that identifies a unit block in the matrix code.

Then, error recovery is performed based on the identifier. That is, the dot not recognized normally is recalculated so as to be generated again. Inverts the data format, detects the compression type, and decompresses it according to the compression type.

Next, the decompressed data format may be converted into an original ID image form and displayed on the screen, and each data may be separated and extracted, for example, an ID content consisting of text may be separately extracted, and image data may be extracted. It can also extract separately (step 13a, 13b: ST-13a, 13b).

Thus, the image of the scanned ID card is divided on one side of the decoding terminal A2, and the image of the ID card reproduced by restoring the matrix code 18 is output on the other side and the images are compared. It is possible to determine (steps 14 and 15: ST-14 and 15). At this time, the comparison of images may be performed by the naked eye or automatically through an image comparison program.

Meanwhile, referring to FIG. 9B, in this case, another example for determining forgery and alteration of an identification card is shown. In order to execute the process illustrated in FIG. 9B, an encoding terminal A1 is required instead of the decoding terminal A2. .

In other words, this does not determine whether the ID card is forged or not by comparing the ID images of which the matrix codes are restored, and compares the generated matrix codes with the scanned matrix codes as a result of encoding the scanned ID images with the matrix codes. It is to determine whether the forgery.

Therefore, in this case, the process of scanning the contents of the identification card and the matrix code, respectively (Stage 20: ST-20); Encoding the identification card content into a matrix code (step 21: ST-21); Comparing the scanned matrix codes with the matrix codes generated by encoding identification information (step 22: ST-22); The process of determining whether the ID card forgery (step 23: ST-23).

On the other hand, the identity authentication system and method using the matrix code according to an embodiment of the present invention is not limited only to the above-described embodiment, various modifications are possible within the scope without departing from the technical gist.

As described above, the identification system and method using the matrix code according to the present invention is very economical because it can accurately determine whether the ID card forgery and tampering without the use of special patterns, special coding paper, special paper, In the case of a passport, it is effective because accurate identification is possible without establishing a separate database as a database, and it does not require access to a separate remote DB server for identification, so identification is quickly performed and device cost is minimized. There is an advantage.
