All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The flow diagrams depicted in the figures are merely illustrative and do not necessarily include all of the elements and operations/steps, nor do they necessarily have to be performed in the order depicted. For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.
The embodiment of the application provides a method and a device for generating an anti-counterfeiting two-dimensional code, a server and a computer readable storage medium. The anti-counterfeiting two-dimensional code generation method can be applied to a server.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for generating an anti-counterfeit two-dimensional code according to an embodiment of the present application.
As shown in fig. 1, the method for generating the anti-counterfeit two-dimensional code includes steps S101 to S105.
S101, acquiring batch codes of products, and acquiring corresponding product IDs according to the batch codes;
when the server reads the batch code of the product, the batch code is the production batch number of the product, a group of numbers or letters plus numbers for identifying "batch", for example, year of production + month of production + number of times of production of batch, and generally consists of two digits of year, month and day of production time. And calling a preset encoding program or an encoder, and encoding the batch codes of the products through the preset encoding program or the encoder to generate the application program of the products. Encoding is the process by which information is converted from one form or format to another, also referred to as code in computer programming languages. Characters, numbers or other objects are coded into digital information by a predetermined coding rule, or the information and data are converted into a predetermined electric pulse signal. For example, when the server acquires the production year + production month + batch production times of the batch code, the production year + production month + batch production times are coded into digital information in the form of graphics, characters, and the like by a preset coding program or a preset coder.
An example is that the server obtains a batch code of the product, and obtains a mapping relation table between the batch code and the product ID. The information between the batch code and the product ID of the product is set in advance as a mapping relation table, for example, the batch code and all product ID numbers of the batch code are recorded in the mapping relation table, and each product has a product ID, and the product IDs are different. A product batch comprises more than one product ID, and all the product IDs are associated with batch codes of the products to generate a mapping relation table. And acquiring the product ID corresponding to the batch of codes through the mapping relation table, wherein the ID can be a combination of numbers, letters, special characters and the like, and the number of the acquired product IDs is not limited.
S102, coding the product ID based on a preset coding program to generate anti-counterfeiting information of the product;
and calling a preset coding program when the product ID is acquired. The code in the code program is the process by which information is converted from one form or format to another, also referred to as code in computer programming language. Characters, numbers or other objects are coded into digital information by a predetermined coding rule, or the information and data are converted into a predetermined electric pulse signal. And encoding the product ID through an encoding program to generate the anti-counterfeiting information of the product.
In an embodiment, specifically referring to fig. 2, step S102 includes: substeps 1021 to substep S1022.
The substep S1021 combines the product ID and a preset code based on the coding program to generate an anti-counterfeiting code corresponding to the product ID;
and acquiring a preset code in the coding program, and combining the product ID and the preset code through the coding program to generate an anti-counterfeiting code corresponding to the product. There are two ways of combination, in the embodiment, the combination is fixed, the preset code is placed at the front, and the product ID is placed at the back of the preset code. For example, when the preset code is 1234 and the product ID is 00012, the anti-counterfeiting code is 123400012. Alternatively, the product ID is preceded by a security code placed behind the product ID, and the security code is 000121234. And (4) random combination, namely, disordering the preset code and the product ID and recombining. For example, when the preset code is 1234 and the product ID is 00012, the anti-counterfeiting code is 010423021.
And a substep S1022 of obtaining the generation timestamp of the anti-counterfeiting code, and using the product ID, the anti-counterfeiting code, and the generation timestamp as anti-counterfeiting information.
When the anti-counterfeiting code is generated, the generation time for generating the anti-counterfeiting code is acquired. For example, when the anti-counterfeiting code is detected to be successfully generated, the time of the current time system is recorded, and the recorded time is used as the generation time stamp. And taking the product ID, the anti-counterfeiting code and the generated timestamp as anti-counterfeiting information, wherein each product ID has one piece of anti-counterfeiting information, and the anti-counterfeiting information of each product ID is different.
S103, generating a tracking code of the product ID according to the batch code and the anti-counterfeiting information;
and when the anti-counterfeiting information is acquired, combining the acquired anti-counterfeiting information with the batch codes to generate the tracking codes of the product. For example, when the anti-counterfeiting information is an anti-counterfeiting symbol, a group of anti-counterfeiting numbers and the like, the batch code is the production year, the production month and the batch production times of the product, the anti-counterfeiting symbol or the anti-counterfeiting numbers of the anti-counterfeiting information are combined with the production year, the production month and the batch production times of the product, the combination sequence is not specified, and the tracking code of the product ID is generated.
In an embodiment, specifically referring to fig. 3, step S103 includes: sub-step S1031 to sub-step S1032.
Step S1031, calculating the batch code, the product ID, the anti-counterfeiting code and the generation time stamp in sequence based on a preset hash algorithm program to respectively obtain hash values of the batch code, the product ID, the anti-counterfeiting code and the generation time stamp;
and calling a preset hash algorithm program when the server acquires the tracking code of the product. The hash algorithm program maps an arbitrary length binary value to a shorter fixed length binary value, this small binary value being referred to as the hash value. Hash values are a unique and extremely compact representation of a piece of data as a value. If a piece of plaintext is hashed and even if only one letter of the piece is altered, the subsequent hash will produce a different value. To find two different inputs whose hash is the same value, the hash value of the data can verify the integrity of the data. And respectively calculating the batch code, the product ID, the anti-counterfeiting code and the generation timestamp through a preset hash algorithm to obtain hash values of the batch code, the product ID, the anti-counterfeiting code and the generation timestamp. For example, the batch code is calculated by a preset hash algorithm program to obtain a hash value of the batch code, the product ID is calculated to obtain a hash value of the product ID, the anti-counterfeit code is calculated to obtain a hash value of the anti-counterfeit code, and the generation timestamp is calculated to obtain a hash value of the generation timestamp.
And a substep S1032 of combining the obtained batch code, the product ID, the anti-counterfeiting code and the hash value of the generated time stamp to generate a tracking code of the product ID.
And when the server respectively obtains the hash value of the batch code, the hash value of the product ID, the hash value of the anti-counterfeiting code and the hash value of the generation timestamp, combining the obtained hash value of the batch code, the hash value of the product ID, the hash value of the anti-counterfeiting code and the hash value of the generation timestamp to generate the tracking code of the product. For example, the combination mode may be a combination mode of the hash value of the batch code + the hash value of the product ID + the hash value of the anti-counterfeit code + the hash value of the generation time stamp to generate the tracking code of the product, or a combination mode of the hash value of the product ID + the hash value of the generation time stamp + the hash value of the anti-counterfeit code + the hash value of the batch code to generate the tracking code of the product ID, and the combination mode is not limited.
The server combines the obtained batch codes, product IDs, anti-counterfeiting codes and hash values for generating time stamps of the products and then maps the product IDs, the anti-counterfeiting codes and the hash values into binary character strings; and if the length of the binary character string is smaller than the target length, performing bit complement on the binary character string to generate the tracking code with the same length as the target length. For example, when a binary string is mapped after a batch code of a product, a product ID, an anti-counterfeit code, and a hash value for generating a time stamp are combined is obtained, the length of the binary string is obtained, the obtained length is compared with a preset target length, and when the length of the binary string is smaller than the target length, the length of the binary string is complemented, for example, when the length of the binary string is 16 bits and the target length is 18 bits, the binary string is complemented by two 0 s so that the length of the binary string is the same as the target length, and a tracking code having the same target length is generated.
Step S104, generating a URL of a product ID according to preset website information and a tracking code;
and when the terminal acquires the tracking code of the product, reading preset website information. The website information is pre-stored in a preset path, for example, http: com.cn is stored in a preset path, the terminal combines the preset website information and the tracking code of the processed product through the read preset website information and the tracking code of the product to generate the URL of the product, and the URL is a Uniform Resource Locator (URL), is a concise representation of the position and the access method of the Resource which can be obtained from the internet, and is the address of the standard Resource on the internet.
And S105, generating an anti-counterfeiting two-dimensional code of the product ID according to the URL based on a preset two-dimensional code generation algorithm.
When the server obtains the URL of the product, the URL of the product is coded through a preset two-dimensional code generation algorithm, and the two-dimensional code of the product is generated. The two-dimensional Code generation algorithm can be Data Matrix, Maxi Code, Aztec, QR Code, etc., and the two-dimensional Code includes a stack two-dimensional Code and a Matrix two-dimensional Code, wherein the stack two-dimensional Code is established on the basis of a one-dimensional bar Code and is stacked into two or more lines as required. The method inherits some characteristics of the one-dimensional bar code in aspects of coding design, checking principle, reading mode and the like, and the reading equipment is compatible with bar code printing and one-dimensional bar code technology. However, as the number of rows increases, the rows need to be determined, and the decoding algorithm and software are not exactly the same as the one-dimensional bar code. The row-row type two-dimensional bar code comprises: code16K, Code 49, PDF417, MicroPDF417, etc. Matrix two-dimensional bar codes (also called checkerboard two-dimensional bar codes) are coded in a rectangular space through different distribution of black and white pixels in a matrix. On the corresponding element positions of the matrix, binary '1' is represented by the appearance of points (square points, round points or other shapes), binary '0' is represented by the absence of the points, and the significance represented by the matrix type two-dimensional bar code is determined by the arrangement and combination of the points. Matrix two-dimensional bar code is a new pattern symbol automatic reading processing code system based on computer image processing technology and combined coding principle. Representative matrix two-dimensional barcodes are: code One, MaxiCode, QR Code, etc.
In an embodiment, specifically referring to fig. 4, step S105 includes: substeps S1051 to substep S1054.
The substep S1051, based on the preset two-dimension code generating algorithm, determining the character type of the URL, and converting the URL into a data character string according to the character set corresponding to the character type;
and the server analyzes the data of the URL through a preset two-dimensional code generation algorithm, determines the character type of the URL and converts the URL into a data character string according to a corresponding character set. And the preset two-dimension code generation algorithm is a QB two-dimension code generation algorithm. For example, data analysis is performed on a URL to determine the character type of the URL, when the URL is determined to be numeric, a character set corresponding to the numeric character is selected, when the URL is english, a character set corresponding to the english character is selected, the URL is converted into data characters through the data characters corresponding to the character set, and the data characters are combined to generate a data character string of the URL.
Substep S1052, performing data encoding on the data character string to obtain a first codeword sequence corresponding to the data character string;
the data character string of the URL is subjected to data coding, the data character string is converted into bit streams, and each 8 bits of the bit streams form a code word sequence of data as a whole. Data may be encoded in a mode for more efficient decoding, such as: for the data: 01234567 encoding, grouping: 01234567, binary: 012 → 0000001100, 345 → 0101011001, 67 → 1000011, the transition sequence: 000000110001010110011000011, converting the character number into binary system: 8 → 0000001000, add mode indicator (upper figure) 0001: 00010000001000000000110001010110011000011, thereby obtaining the first code word sequence of the data character string.
The substep S1053, carry on the error correction coding to the first codeword sequence through presetting the error correction coding grade, obtain the error correction code word of the first codeword sequence;
and selecting the error correction level of the URL, wherein the higher the error correction level is, the smaller the real data capacity is under the condition of a preset rule. And carrying out error correction coding on the data character string of the URL according to the error correction level of the URL, blocking the code word sequence as required, and acquiring error correction code words according to the error correction level and the blocked code words. In the case of determining the two-dimensional code specification and the error correction level, the total number of codewords and the number of error correction codewords that can be accommodated by the two-dimensional code specification and the error correction level are determined, for example: version 10, error correction level H, can accommodate a total of 346 codewords, of which 224 error correction codewords, that is, approximately 1/3 codewords in the two-dimensional code region, are redundant. For these 224 error correction codewords, it can correct 112 replacement errors (e.g., black-white inversion) or 224 data read errors (unreadable or undecodable).
And a substep S1054 of adding the error correction code word into the first code word sequence to generate a second code word sequence, and adding the second code word sequence into a preset matrix to generate the anti-counterfeiting two-dimensional code of the product ID.
And when the error correcting code word to be corrected is acquired, the error correcting code word is put into the first code word sequence to generate a second code word sequence. The final data information is constructed by a preset matrix, and the sequences generated above are put in blocks in order under the condition determined by the matrix specification. For example, the data is partitioned into blocks as prescribed, then calculations are performed on each block to obtain corresponding blocks of error correction code words, which are sequentially formed into a sequence to be added to the original data. Such as: d1, D12, D23, D35, D2, D13, D24, D36,. D11, D22, D33, D45, D34, D46, E1, E23, E45, E67, E2, E24, E46, E68. And (3) putting the detection pattern, the separator, the positioning pattern, the correction pattern and the code word module into a matrix, and filling the complete sequence into the area of the two-dimensional code matrix with the corresponding matrix specification to generate the anti-counterfeiting two-dimensional code.
In this embodiment, the anti-counterfeiting information is generated from the product ID, the URL is generated from the anti-counterfeiting information, and the generated URL is used as the generation information of the two-dimensional code, so that the two-dimensional code contains the anti-counterfeiting information of the product to achieve the anti-counterfeiting effect.
Referring to fig. 5, fig. 5 is a schematic flow chart illustrating a method for generating an anti-counterfeiting traceability two-dimensional code according to the embodiment.
As shown in fig. 5, the method for generating the anti-counterfeiting tracing two-dimensional code includes steps S201 to S211.
Step S201, obtaining a batch code of a product, and obtaining a corresponding product ID according to the batch code.
When the server reads the batch code of the product, the batch code is the production batch number of the product, a group of numbers or letters plus numbers for identifying "batch", for example, year of production + month of production + number of times of production of batch, and generally consists of two digits of year, month and day of production time. And calling a preset encoding program or an encoder, and encoding the batch codes of the products through the preset encoding program or the encoder to generate the application program of the products. Encoding is the process by which information is converted from one form or format to another, also referred to as code in computer programming languages. Characters, numbers or other objects are coded into digital information by a predetermined coding rule, or the information and data are converted into a predetermined electric pulse signal. For example, when the server acquires the production year + production month + batch production times of the batch code, the production year + production month + batch production times are coded into digital information in the form of graphics, characters, and the like by a preset coding program or a preset coder.
An example is that the server obtains a batch code of the product, and obtains a mapping relation table between the batch code and the product ID. The information between the batch code and the product ID of the product is set in advance as a mapping relation table, for example, the batch code and all product ID numbers of the batch code are recorded in the mapping relation table, and each product has a product ID, and the product IDs are different. A product batch comprises more than one product ID, and all the product IDs are associated with batch codes of the products to generate a mapping relation table. And acquiring the product ID corresponding to the batch of codes through the mapping relation table, wherein the ID can be a combination of numbers, letters, special characters and the like, and the number of the acquired product IDs is not limited.
And S202, coding the product ID based on a preset coding program to generate the anti-counterfeiting information of the product.

The code in the code program is the process by which information is converted from one form or format to another, also referred to as code in computer programming language. Characters, numbers or other objects are coded into digital information by a predetermined coding rule, or the information and data are converted into a predetermined electric pulse signal. And encoding the product ID through an encoding program to generate the anti-counterfeiting information of the product.
And S203, generating a tracking code of the product ID according to the batch code and the anti-counterfeiting information.
And when the anti-counterfeiting information is acquired, combining the acquired anti-counterfeiting information with the batch codes to generate the tracking codes of the product. For example, when the anti-counterfeiting information is an anti-counterfeiting symbol, a group of anti-counterfeiting numbers and the like, the batch code is the production year, the production month and the batch production times of the product, the anti-counterfeiting symbol or the anti-counterfeiting numbers of the anti-counterfeiting information are combined with the production year, the production month and the batch production times of the product, the combination sequence is not specified, and the tracking code of the product is generated.
And step S204, generating a URL of the product ID according to the preset website information and the tracked code.
And when the terminal acquires the tracking code of the product, reading preset website information. The website information is pre-stored in a preset path, for example, http: com.cn is stored in a preset path, the terminal combines the preset website information and the tracking code of the processed product through the read preset website information and the tracking code of the product to generate the URL of the product, and the URL is a Uniform Resource Locator (URL), is a concise representation of the position and the access method of the Resource which can be obtained from the internet, and is the address of the standard Resource on the internet.
And S205, generating the anti-counterfeiting two-dimensional code of the product ID according to the URL based on a preset two-dimensional code generation algorithm.
And the server analyzes the data of the URL through a preset two-dimensional code generation algorithm, determines the character type of the URL and converts the URL into a data character string according to a corresponding character set. And the preset two-dimension code generation algorithm is a QB two-dimension code generation algorithm. For example, data analysis is performed on a URL to determine the character type of the URL, when the URL is determined to be numeric, a character set corresponding to the numeric character is selected, when the URL is english, a character set corresponding to the english character is selected, the URL is converted into data characters through the data characters corresponding to the character set, and the data characters are combined to generate a data character string of the URL.

Data may be encoded in a mode for more efficient decoding, such as: for the data: 01234567 encoding, grouping: 01234567, binary: 012 → 0000001100, 345 → 0101011001, 67 → 1000011, the transition sequence: 000000110001010110011000011, converting the character number into binary system: 8 → 0000001000, add mode indicator (upper figure) 0001: 00010000001000000000110001010110011000011. a first codeword sequence of the data string is obtained.
And selecting the error correction level of the URL, wherein the higher the error correction level is, the smaller the real data capacity is under the condition of a preset rule. And carrying out error correction coding on the data character string of the URL according to the error correction level of the URL, blocking the code word sequence as required, and acquiring error correction code words according to the error correction level and the blocked code words. In the case of determining the two-dimensional code specification and the error correction level, the total number of codewords and the number of error correction codewords that can be accommodated by the two-dimensional code specification and the error correction level are determined, for example: version 10, error correction level H, can accommodate a total of 346 codewords, of which 224 error correction codewords, that is, approximately 1/3 codewords in the two-dimensional code region, are redundant. For these 224 error correction codewords, it can correct 112 replacement errors (e.g., black-white inversion) or 224 data read errors (unreadable or undecodable).
And when the error correcting code word to be corrected is acquired, the error correcting code word is put into the first code word sequence to generate a second code word sequence. The final data information is constructed by a preset matrix, and the sequences generated above are put in blocks in order under the condition determined by the matrix specification. For example, the data is partitioned into blocks as prescribed, then calculations are performed on each block to obtain corresponding blocks of error correction code words, which are sequentially formed into a sequence to be added to the original data. Such as: d1, D12, D23, D35, D2, D13, D24, D36,. D11, D22, D33, D45, D34, D46, E1, E23, E45, E67, E2, E24, E46, E68.
