The present invention relates to the technical field of data encryption, in particular to a data anti-counterfeiting method and device based on gene word technology

Background technique

With the continuous development of information technology, computers, servers and other equipment between various units or departments within a unit can be connected to each other through a local area network or the World Wide Web, making the exchange of official documents or documents, especially electronic documents or documents exchange through the network increasingly frequently. In order to prevent electronic documents or documents from being maliciously stolen or forged, it is necessary to encrypt or anti-counterfeit the data in electronic documents or documents, for example: use digital watermarking technology for anti-counterfeiting treatment, so as to protect electronic documents or documents from being forged.

Gene word technology is a new anti-counterfeiting technology for electronic documents that has emerged in recent years. The gene font library is a special font library. The characters in the gene font library are very similar to the characters in the normal font library in shape but there are subtle differences, and these The difference is difficult to detect with the naked eye, and a special program is needed to identify it, and the number and type of characters in the gene font can be changed as needed. It is equivalent to making some or all of the characters in the entire electronic document serve as anti-counterfeiting marks, and it is difficult for people who do not have the same genetic font library as the encrypted side to forge electronic documents.

The problem with the existing technology is that with the wide application of genetic word technology, the encrypted gene font library has been illegally copied. Unscrupulous people may obtain the encrypted genetic font library and use the obtained genetic font library to forge electronic documents, reducing data security.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

In order to make the advantages of the technical solution of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

Example 1

The embodiment of the present invention provides a data anti-counterfeiting method based on genetic word technology, as shown in Figure 1, including:

The method flow in this embodiment can be executed by the encryption end, and the encryption end includes a computer and a server capable of encrypting data using genetic word technology.

Step 101, extract the character stream in the data to be encrypted.

Wherein, the data to be encrypted includes at least one character stream.

Specifically, in this embodiment, the data to be encrypted may be various text documents stored in the encryption terminal, such as electronic documents or documents, and the character stream may be a series of continuous characters in the electronic document. For example:

In the computer, an electronic document to be encrypted is stored in txt format (or other formats such as word, pdf, etc.), and the content of the electronic document includes an article, so the character stream extracted by the computer can be Every sentence in the article is separated by punctuation, for example: the content of the electronic document to be encrypted is "Quiet Night Thoughts" composed of 20 simplified Chinese characters: "The moonlight in front of the bed is suspected to be frost on the ground. Raise your head to look at the bright moon and bow your head to think Hometown.", 20 simplified Chinese characters are divided into 4 sentences by 4 punctuation marks, the computer can recognize these punctuation marks through the existing character recognition technology and use the 4 sentences separated by punctuation marks as the extracted character stream, then The computer extracts a total of 4 character streams: "Moonlight in front of the bed", "Suspected to be frost on the ground", "Looking up at the bright moon", and "Looking down at my hometown".

Step 102, obtain the characters to be replaced in the current character stream according to the preset gene word list.

Wherein, the gene word list is set by the user or automatically set by the encryption end, the gene word list includes part or all of the characters in the gene word library, and the characters to be replaced are in the character stream with the same font shape as the characters in the gene word list character of. Concretely, in this embodiment, the list of genetic characters can be a list of one-to-one correspondence between the characters in the normal font and the characters in the genetic font, as shown in Table 1:

Table I

Genetic characters are very similar to the characters in the normal font library in shape, but there are subtle differences. As shown in Table 1, the genetic character has a small dot in the shape. In practical applications, the variation of the glyph of the genetic character may be more complex and difficult to recognize, and this is only for illustration, and the glyph of the genetic character is not limited.

Further, in this embodiment, the specific content of the gene word list can be preset by the user or the encryption terminal, and there is an encryption key for performing anti-counterfeiting processing on this electronic document in the device for anti-counterfeiting verification of an electronic document. A list of gene words with the same end. Therefore, the device for anti-counterfeiting verification can verify whether there is a gene word that does not belong to the gene word list after finding out the gene word in the electronic document. If there is a gene word that does not belong to the gene word list, it means that the electronic document is Forged.

Step 103, replacing the characters to be replaced with characters in the gene font library.

For example: according to Table 1, ordinary characters can be characters in the normal font library, and the same character can have multiple fonts, for example: the character to be replaced in the character stream "Moonlight in front of the bed" is: "bed" (italics_GB2312 ), "Ming" (italics _GB2312), "month" (italics _GB2312).

The method flow from step 102 to step 103 is repeated until the method flow from step 102 to step 103 is completed for all character streams extracted from the data to be encrypted.

The data anti-counterfeiting method based on the genetic word technology provided by this embodiment can determine the characters that need to be replaced according to the genetic word list. Compared with the unique encryption result generated only through the genetic word library in the prior art, a different genetic word list is used. Processing the data to be encrypted will generate different encryption results. If the genetic word library on the encrypted side is illegally copied, the unscrupulous personnel cannot forge the data because the genetic word list is not used, thus solving the problem of reduced data security caused by the illegal copying of the genetic word library on the encrypted side in the prior art, thereby improving Data Security.

Example 2

The embodiment of the present invention provides a data anti-counterfeiting method based on genetic word technology, as shown in Figure 2, including:

The method flow in this embodiment can be executed by the encryption end, and the encryption end includes a computer and a server capable of encrypting data using genetic word technology.

Step 201, extract the character stream in the data to be encrypted.

Wherein, the data to be encrypted includes at least one character stream.

Step 202, obtain the character to be replaced in the current character stream according to the preset gene word list.

Wherein, the gene word list is set by the user or automatically set by the encryption end, the gene word list includes part or all of the characters in the gene word library, and the characters to be replaced are in the character stream with the same font shape as the characters in the gene word list character of.

Step 203, obtaining a character string input by the user or automatically generated by the encryption terminal.

Specifically, in this embodiment, the encryption terminal can obtain a character string, which can be input by the user into the encryption terminal, or automatically generated by the encryption terminal, or directly obtained by the encryption terminal and pre-stored in the encryption terminal. The string can be a continuous string of text, symbols, numbers, etc. For example, after the encryption terminal obtains the characters to be replaced in the character stream in "Quiet Night Thoughts", the user can input the simplified Chinese character string "一" to the encryption terminal. The first poem", the encryption end can perform follow-up processing on the four character streams in "Quiet Night Thoughts" according to the string "a poem".

Step 204, converting the character string into a character string in binary format according to a preset algorithm.

Wherein, the characters in the string in the binary format include 1 and 0.

Specifically, in this embodiment, the encryption end can convert the character string input by the user or automatically generated by the encryption end into a string in binary format through a preset algorithm, for example: the encryption end can convert the "a poem" input by the user "This character string is first converted to ASCII code, and then a string of strings in binary format is generated again through the MD5 algorithm based on the character string converted to ASCII code, such as: "101".

Step 205, obtain the characters to be replaced in the current character stream according to the preset gene word list.

Step 206, divide the characters in the current character stream into N groups according to the order of arrangement.

Wherein, the number of characters in the string in binary format is N, and the number of characters to be replaced is M. Then the number of characters to be replaced included in each group is the largest integer less than or equal to M/N, and the number of characters to be replaced included in the last group is the remainder or M/N of M/N, wherein the characters in binary format The characters in the string correspond to each group one by one according to the order of arrangement, that is, one character in the string in binary format corresponds to one group.

For example, if the character string in binary format is "101", then N=3; the current character stream is "Moonlight in front of the bed", and according to the encrypted side in Table 1, we can know that the characters to be replaced are: "bed" (italics_GB2312), "明" (italics_GB2312), "month" (italics _GB2312), then M=3. Then the above text can be divided into the following three groups:

Group 1: Bed

The second group: Qian Ming

The third group: month

For each group, take the processing flow corresponding to step 207:

Step 207, if the corresponding character in the string in the binary format is 1, replace the character to be replaced in this group with the character in the gene font.

For example: if the first group corresponds to "1", replace "bed (italics_GB2312)" with "bed`" in the gene font library.

If the corresponding character in the string in the binary format is 0, no processing is performed.

For example: if the second group corresponds to "0", then the second group will not be processed.

The method flow corresponding to step 207 is repeated until the above processing flow is completed for each group divided by the current character stream.

For example: "Moonlight in front of the bed" goes through the corresponding method flow from step 206 to step 207, and the result is "moonlight in front of the bed", where "bed" and "month" are the genes in the gene font Character.

The method flow corresponding to step 206 to step 207 is repeated until the method flow corresponding to step 206 to step 207 is completed for all character streams extracted from the data to be encrypted.

For example: After the above-mentioned anti-counterfeiting treatment of "Quiet Night Thoughts", it is finally " Former Ming Dynasty Light, suspected to be frost on the ground. raise Wangming Low Miss hometown. "Wherein, the characters in the wireframe are gene words.

The data anti-counterfeiting method based on the gene word technology provided by this embodiment can determine the characters that need to be replaced according to the gene word list. Since the content of the gene word list is preset by the user or the encryption end, the encryption end performs anti-counterfeiting processing on the data The genetic word list needs to be used to determine the characters to be replaced, and the types and quantities of characters to be replaced are different according to different gene word lists. That is, using different gene word lists to process the data to be encrypted will lead to different encryption results, and In the process of encrypting the data, a character string input by the user or automatically generated is also required, thereby further increasing possible encryption results. If the gene font library on the encryption side is illegally copied, the unscrupulous personnel cannot forge the data because the gene word list and character strings are useless, thus solving the problem of reduced data security caused by the illegal copying of the gene font library on the encryption side in the prior art , thereby improving data security.
