Description

Technical Field

[0001] The invention relates to two-dimensional code technology. Background Art

[0002] "Hanxin Code" is a Chinese national standard (GB / T21049-2022) implemented on October 1, 2022. The standard specifies the symbol characteristics and symbol structure, data encoding and symbol representation, symbol printing, symbol quality, decoding process, reference decoding algorithm, data transmission and other technical contents of Hanxin Code; Summary of the invention

[0003] The purpose of the present invention is to provide a composite Hanxin code verification method and system based on a coding conversion mechanism, which is characterized by comprising a coding generation system, a Hanxin code generation system, and a verification server;

[0004] The code generation system generates the composite Chinese Xin code by the following steps:

[0005] 1) Generate a first code and a second code;

[0006] The first code includes a character sequence K and a character sequence A, and the character sequence A is a first signature of the character sequence K; the second code includes a character sequence K and a character sequence B, and the character sequence A is a second signature of the character sequence K; the character sequence A and the character sequence B have the same length and format;

[0007] 2) Performing a transformation on the first code: inserting a fill character between the character sequence K and the character sequence A constituting the first code; performing a transformation on the second code: inserting a fill character between the character sequence K and the character sequence B constituting all the character sequences of the second code;

[0008] 3) According to the Hanxin code encoding process, the transformed first code and the second code are used as input data to generate a first data codeword sequence and a second data codeword sequence;

[0009] The Hanxin code generation system converts the first data codeword sequence and the second data codeword sequence into a codeword sequence to be arranged according to the Hanxin code generation rule, and then arranges the first Hanxin code symbol and the second Hanxin code symbol;

[0010] When printing the symbol, the second Chinese Xin code symbol is printed on the surface of the substrate, and then the second Chinese Xin code symbol is covered with a fragile material; after the fragile material is covered, only the second Chinese Xin code symbol and the first Chinese Xin code symbol have a partial or complete information encoding area with the same pattern exposed; finally, the pattern is continued to be printed on the fragile material to form a complete first Chinese Xin code symbol;

[0011] During verification, the code scanning device can transmit the read information to the verification server by scanning the first Chinese Xin code symbol to be verified and the second Chinese Xin code symbol to be verified respectively;

[0012] After receiving the information, the verification server performs verification on the first code to be verified in the following situations:

[0013] I) verifying the first code to be verified to determine that it is the correct first code, and if the second code has not been received, the first code to be verified is verified;

[0014] II) verifying the first code to be verified to determine that it is the correct first code; if the second code has been received before, the first code to be verified is not verified;

[0015] After receiving the information, the verification server verifies the second code to be verified; after verifying the second code to be verified, if it is the first time to determine that the correct second code has been received, save a verification record of receiving the correct second code;

[0016] Further, after the first data codeword sequence and the second data codeword sequence are generated, the first data codeword sequence and the second data codeword sequence are transformed according to the same rule, so that the nominal modules corresponding to the character sequence A of the first data codeword sequence are concentrated in the continuous graphic part of the code diagram of the first Hanxin code symbol, and the nominal modules corresponding to the character sequence B of the second data codeword sequence are concentrated in the continuous graphic part of the code diagram of the second Hanxin code symbol;

[0017] After the code scanning device scans the first Chinese Xin code symbol and the second Chinese Xin code symbol, the code read needs to be subjected to an inverse transformation corresponding to the transformation to obtain the correct first code and second code;

[0018] Furthermore, when the Hanxin code generation system converts the first data codeword sequence into the codeword sequence to be arranged, the data codewords corresponding to the character sequence A are arranged in a concentrated manner in the codeword sequence to be arranged;

[0019] Furthermore, when the Hanxin code generation system converts the second data codeword sequence into the codeword sequence to be arranged, the rule adopted is the same as the rule of "converting the first data codeword sequence into the codeword sequence to be arranged", so that the data codewords corresponding to the character sequence B are centrally arranged in the codeword sequence to be arranged;

[0020] Further, in step 1), at least one padding character is inserted at each location, so that in the subsequent encoding process, the codes corresponding to the character sequence K and the character sequence A are not allocated to the same group; in step 2), at least one padding character is inserted at each location, so that in the subsequent encoding process, the codes corresponding to the character sequence K and the character sequence B are not allocated to the same group;

[0021] Furthermore, the character sequence A and the character sequence B have the same length, and the number of padding characters inserted in step 1) and step 2) is the same;

[0022] Further, the first Hanxin code symbol and the second Hanxin code symbol have the same version, error correction level and masking scheme;

[0023] Further, for the first code, padding characters are inserted before and after all character sequences constituting the first code, and between character sequence K and character sequence A; for the second code, padding characters are inserted before and after all character sequences constituting the second code, and between character sequence K and character sequence B;

[0024] Furthermore, when the first data codeword sequence and the second data codeword sequence are transformed according to the same rule, the nominal module corresponding to the character sequence A of the first data codeword sequence is concentrated at the tail of the code diagram of the first Hanxin code symbol, and the nominal module corresponding to the character sequence B of the second data codeword sequence is concentrated at the tail of the code diagram of the second Hanxin code symbol;

[0025] Furthermore, during verification, after scanning the first Chinese Xin code symbol to be verified and the second Chinese Xin code symbol to be verified, the code scanning device needs to perform an inverse transformation corresponding to the entire transformation process on the collected information to obtain information corresponding to the first code and the second code;

[0026] Further, a mode indicator is inserted before and / or after the character sequence A and the character sequence B;

[0027] The technical effect of the present invention is unquestionable. A composite Hanxin code that meets the verification rules can be generated and verified. The composite Hanxin code can be applied to the fields of commodity anti-counterfeiting, process management, etc. to ensure the authenticity of the commodity assigned with the composite Hanxin code or the reliability of the process management process.
