Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

3 to 8, an electronic cigarette encryption system according to an embodiment of the present invention is an electronic cigarette system in which an electronic cigarette having an electronic cigarette is provided to a document to be issued, And an audience management server 100.

First, the electronic person can use a virtual electronic person by capturing and imaging an actual electronic person, or use an electronic person who is made by a program for producing an electronic person. Here, the production program, which is an electronic organ, creates the electronic tag by inputting the frame information for the border of the outer border and the information about the characters located inside the border in the electronic watermark. These electronic stamps are stamped on documents that require certification issued by a government agency. And a representative of a person or a company or a company name is formed on the inside of the roughly rectangular frame 10. That is, the user can confirm the authenticity of the document by checking the electronic tag displayed on the screen of the monitor or the mobile phone connected to the computer.

As shown in FIG. 1, the electronic museum is composed of a rectangular frame 10 which surrounds characters and letters, 'President of Dong-A & Associates Literary Association'. In addition, the rectangular frame 10 may have various colors, and it is preferable that the red color is displayed in a dark color.

The electronic management server 100 includes a management unit 110, a frame recognition unit 120, a frame dividing unit 130, a code generation unit 140, and a code input unit 150 .

The electronic tube managing unit 110 stores and manages data that is an electron tube in a DB. The electronic managing unit 110 divides and manages the border information for the border of the outline and the information about the characters located inside the border in the electronic tube.

The border recognizing unit 120 recognizes the border 10 in the electronic tube managed by the managing unit 110 which is the electronic tube. That is, the frame recognition unit 120 receives the frame information managed by the control unit 110, and recognizes the frame 10 of the electronic shop.

The frame dividing unit 130 divides the frame 10 recognized by the frame recognizing unit 120 into a plurality of regions 20. The edge dividing unit 130 divides one area 20 into 4-bit sizes in the edge 10 of the electron tube recognized by the edge recognizing unit 111. In this case, And is divided into a plurality of regions (20). As a result, a binary number can be input into one area 20 divided into 4 bits. Therefore, a cipher, which is an electron tube constituted by binary numbers, can be input to the area 20. [

Therefore, the electronic watermark is managed in a state in which the region 20 for inputting the electronic cipher is divided into the frame 10.

The electronic cryptographic code generation unit 140 generates a cryptographic key for input to the frame 10 of the electronic cognizant recognized by the cognitive frame recognition unit 120 and stores the generated cryptographic key in the DB for management . The electronic cryptographic code generation unit 140 is configured to generate the electronic cryptographic code in binary numbers, and can randomly generate various binary codes. That is, binary numbers to be input to the electronic tag can be generated each time a document is issued.

The electronic cryptographic key input unit 150 inputs the electronic cryptographic key to the edge 10 of the electronic cognitive unit recognized by the frame recognition unit 120. The binary coded key generated by the electronic cryptographic key generation unit 140 is input to the frame dividing unit 120, Into the divided region (20) in the memory (130).

For example, if the decryption key to be input is a decimal '2', the binary number input to the 4-bit area 20 is '0010'. Therefore, four regions 20 are used when the decryption key is '2016', and 0010, 0000, 0001, and 0110 are input to the four regions 20, respectively. The binary number input to the region 20 formed along the edge 10 of the electron tube can be identified through the server.

The management server 100, which is an electronic organization, includes an issuer information management unit 160 that manages the issuer information of the issuer issuing the document, and an applicant information management unit 170 that receives and manages the applicant information of the applicant who requests to issue the document .

The issuer information management unit 160 stores and manages the issuer information in the DB. For example, the issuer information may consist of the name of the school issuing the document such as a report card, the name of the president, the date of issue of the document, and so on.

The applicant information management unit 170 receives the applicant information of the applicant applying for document issuance, stores it in the DB, and manages it. For example, applicant information may consist of applicant name, applicant address, applicant date, and so on.

The electronic cryptographic code generation unit 140 randomly assigns binary numbers to the applicant information input from the applicant information management unit 130 and the issuer information managed by the issuer information management unit 120 to generate the electronic cryptographic code. Here, randomly assigned passwords should always be new binary numbers.

More specifically, a binary number for the applicant's name, a binary number for the applicant's address, and a binary number for the applicant's date are arbitrarily generated, a binary number for the school name, issuer information, a binary number for the president's name, Generates a binary number for the date the document was issued.

In this way, when the applicant inputs applicant information while applying for a document such as a report card, the electronic secret information generation section 140 generates an electronic secret number password using the applicant information and the issuer information. Therefore, by decrypting the electronic cipher, it is possible to identify who the applicant is, when the application date is, who is the issuer, and when the issuance date is, so that the authenticity of the issued document can be easily determined.

Also, the electronic cryptographic code generation unit 140 may be configured to generate the electronic cryptographic code as image pixel values for different colors in binary numbers '0' and '1'.

The code input unit 150 receives the image pixel values of RGB (255, 0, 0) in the region 20 to which the binary number '0' is input, And input image pixel values of RGB (255, 10, 10) to the image sensor 20.

Therefore, the encryption generating unit 140 can generate the image pixel values for the colors corresponding to '0' and '1' of the binary number for each 4 bits of the area 20, respectively. In other words, you can enter binary numbers by setting different image pixel values. When the RGB values are '255, 10, 10', the R (red) value is high and the remaining G (green) and B (blue) values are low, Although only the red color appears, the G (green) and B (blue) values can also be recognized through the server.

Accordingly, when the encryption input unit 150, which is an electronic tube, inputs image pixel values into the area 20 formed along the frame 10 of the electron tube, it is difficult for the general people to forge and forge because they can not distinguish the minute color difference.

Also, the management server 100, which is an electronic management server, includes a decryption unit 180, which is an electronic facility for decrypting an electronic key, which is an electronic key included in a document input through wired or wireless communication from an external server, (190) which compares the decrypted electronic cipher with the applicant information and the issuer information and determines whether or not they match.

The decryption unit 180 includes a recognizing unit 181 for recognizing the frame 10 included in the document and recognizing the region 20 in the recognized frame 10, And a binary number verifying unit 182 for verifying the binary number in the area 20 recognized by the unit 181.

Therefore, when a document is input while requesting authenticity of the document from an external server, the recognition unit 181 recognizes the region 20 from the edge 10 of the electronic tube included in the document.

If the binary number is not confirmed in the binary number confirmation unit 182, the electronic determination unit 190 determines that the binary number is OK. If the binary number is verified in the binary number verification unit 182, the encryption determination unit 190 determines that the binary number is normal. Therefore, if the binary number is not confirmed in the binary number check unit 182, the electronic number password determination unit 190 determines that the electronic number is not given the electronic number password, and can determine that the electronic number is falsified .

In this manner, the encryption determination unit 190, which is an electronic apparatus, can accurately determine whether the issued document is authentic through the process of checking the binary number.

The decryption unit 180 includes a recognition unit 181 that recognizes the frame 10 in the electronic tube included in the document and recognizes the region 20 in the recognized frame 10, An RGB recognition unit 183 for recognizing RGB image pixel values in the region 20 recognized by the human recognition unit 181; , And if the image pixel value recognized by the RGB recognizing unit 183 is RGB (255, 10, 10), the image decoding unit 184 decodes the binary image into '1' ).

When the RGB recognizing unit 183 recognizes the image pixel value, the image decoding unit 184 decodes whether the recognized image pixel value is binary '0' or '1'.

If the image pixel value is not recognized by the RGB recognition unit 183, the electronic determination unit 190 determines that the image is not normal. If the RGB image recognition unit 183 recognizes the image pixel value, the encryption determination unit 190 determines that the image is normal.

The encryption decryption unit 190 compares the decrypted binary number in the image decryption unit 184 with the binary number generated and managed in the encryption key generation unit 140 to determine whether or not the binary value matches. Thus, if the decoded binary number matches the binary number managed by the encrypting unit 140, which is the electronic cipher, it is determined as normal and the document can be proved to be the original that is not forged.

As described above, the encryption decryption unit 190 is a first step for precisely recognizing a difference in image pixel value with respect to a minute color formed in the frame 10 of the electron tube, and a binary process corresponding to the image pixel value , It is possible to accurately determine whether the document is authentic or not.

As described above, according to the present invention, it is possible to divide the rectangular frame 10 formed around the electron tube and input a password, which is an electronic tube which is a binary number, or a password, which is an electronic tube which becomes an image pixel value. That is, not only a normal document including the encrypted electronic certificate can be issued through a computer or a smart phone, but also a forgery-alteration of the issued document can be prevented. In addition, it is possible to accurately determine whether the document requesting authenticity is decrypted by decrypting a code, which is an electronic tube, which is a binary number, and an electronic tube, which is an image pixel value, on the edge 10 of the electronic tube.

9 and 10, the encryption-decryption method, which is an electronic tube according to an embodiment of the present invention, includes an edge recognition step of recognizing an edge 10 of an electronic tube stored and managed in a server, A border dividing step S20 of dividing the recognized border 10 of the electron tube into a plurality of areas 20 and an electronic tube cipher to be input to the border 10 of the divided electronic cube, A password input step (S40) of inputting a generated electronic cipher into the area (20) of the divided frame (10), a password inputting step (S40) of issuing a document, An applicant information management step (S50) for managing information, an applicant information management step (S60) for receiving and managing applicant information of an applicant applying for a document issuance, an electronic information management step The electronic cipher that decrypts And dock step (S70), comparing the decrypted electronic official seals password and the applicant information and the issuer information includes electronic official seals password discrimination step (S80) to determine whether they match.

In this case, in the edge dividing step S20, the area 20 of the frame 10 is divided into 4 bits, and in the code generating step S30, the electronic cipher is inputted into the 4-bit area 20 The image pixel value of RGB (255, 0, 0) is input to the area 20 where binary '0' is input in the code input step S40, which is a binary number, The image pixel values of RGB (255, 10, 10) are input to the input area 20 and the decryption step S70 of the electronic image recognizes the frame 10 from the electronic image included in the document, An RGB recognition step S72 for recognizing image pixel values of RGB in the recognized area 20 and a recognizing step S72 for recognizing the recognized image pixel values 1 " if the image pixel value recognized by the RGB recognizing unit 183 is RGB (255, 10, 10), and " Image detoxification (S73). If it is determined that the image pixel value is not recognized by the RGB recognition unit 183 in the password determination step S80, the image recognition unit 183 determines that the image pixel value is abnormal. If the RGB image recognition unit 183 recognizes the image pixel value, .

As described above, according to the present invention, it is possible to set the electronic cipher to the electronic cipher to prevent forgery modulation of the document, decipher the electronic cipher set in the electronic cipher to determine the forgery modulation of the document, Which can be widely used.
