Detailed Description
The technical scheme of the invention is further explained by combining the drawings and the embodiment.
As shown in fig. 1-5, the strong encryption anti-counterfeiting anti-channel conflict commodity code is in a two-dimensional code form, and carries link information, wherein the link information is formed by adding an intermediate code after being encrypted by 3DES to a link website.
The intermediate code consists of a sequence code and a check code, wherein the sequence code is an factory code of a product, the check code is an n-bit digital code randomly generated by a system, and the first bit is not 0. In order to enhance the anti-counterfeiting property, the sequence code consists of numbers and letters.
The sequence code is equally divided into n segments, then the sequence code segments are rearranged according to the check code to form a recombined code, and the attribute code is added at the front end of the recombined code and inserted into the insertion position of the check code, thereby forming the intermediate code. The insertion bit is the first digit of the check code.
The specific generation process of the commodity code is as follows:
s1: generating a check code and a sequence code, wherein the check code and the sequence code are generated by a system, the check code is an n-bit digital code of a random sequence, the first bit of the n-bit digital code is not 0, and the sequence code is an outgoing factory code of a product;
s2: dividing the fragments, and equally dividing the sequence code into n fragments;
s3: rule generation, generating insertion bit rule P according to first digit of check code1Generating a scrambling rule { P) from the check code1，P2，P3，......，Pn}；
S4: generating recombination code, recombining sequence code segments according to a scrambling rule, wherein the ith sequence code segment corresponds to the scrambling rule PiI +1 th sequence code segment corresponds to a scrambling rule Pi+1(ii) a If Pi>Pi+1If so, the ith sequence code segment is inserted into the (i + 1) th sequence code segment;
s5: adding an attribute code, namely adding a product attribute code at the front end of the recombination code;
s6: generating intermediate code, inserting recombination code carrying attribute information into P-th of check code according to insertion position rule1Bit and P1Between +1 bits, if P1+1>n, directly inserting the recombination code carrying the attribute information into the rear end of the check code;
s7: the system encryption is carried out, and data encryption is carried out on the intermediate code according to an encryption rule;
s8: synthesizing a link, and merging the encrypted intermediate code into a link website;
s9: and (4) form generation, namely outputting the link in a two-dimensional code form.
The step S8 includes generating a main code and generating an auxiliary code, where the main code is generated by directly converting a link into a two-dimensional code form, and the auxiliary code is formed by inverting a data bit color block of the main code based on the main code. Corresponding to the two-dimensional code form of fig. 5, the version information color blocks 1, the positioning bar color blocks 2, the blank region 3, the position detection image color blocks 4, the correction pattern color blocks 5, and the format information color blocks 6 of the main code and the auxiliary code are all the same in position color, but the data code color blocks 7 are opposite in color.
For ease of understanding, the present application provides a specific example, the encryption process is as follows:
the check code generated by the system is 39362, and the sequence code is 12345A678901B2345678
The rule of insertion bit is 3, and the rule of scrambling is {3, 9, 3, 6, 2}
The sequence code segment is 12345A678901B2345678
The fragment after the disruption is 567812348901B2345A67
C567812348901B2345A67 after filling in item attribute code (SKU) C
Intermediate code 393C567812348901B2345A6762
The commodity code information is as follows (omitting 3DES encryption process)
https://abc.example.com/api/sc＝393C567812348901B2345A6762
If the check code is 79362, the intermediate code is 79362C56788901B23412345A 67.
The decryption process is as follows (ignoring 3DES decryption):
intermediate code 393C567812348901B2345A6762
According to the first 3, it can be seen that the attribute code and the reconfiguration code start from the fourth bit, so the attribute code is C, the reconfiguration code is 567812348901B2345a67, and the check code is 39362.
The disorder rule is {3, 9, 3, 6, 2}
The sequence code is 12345A678901B2345678
When the consumer inquires about the authenticity, the commodity code is firstly scanned by using a two-dimensional code scanning tool. If the consumer scans the main code, the interface program can directly identify the website link; if the consumer scans the auxiliary code, the website address identified by the interface program is linked wrongly or can not be identified, and at the moment, the interface program automatically turns over the commodity code color block and then identifies again.
And if the website link is not the link set by the manufacturer, automatically judging the product as a pirate product.
If the website link is correct, the server performs 3DES decoding on the commodity code information, then sequentially extracts the intermediate code and the sequence code, and finally queries the sequence code in a database. If the serial code does not exist, the product is automatically regarded as a pirate product. If the sequence code exists, further inquiring whether the sequence code is the first inquiry. If the query is the first query, the query is directly regarded as a genuine product, and if the query is the multiple queries, a prompt (genuine product, Nth query) is provided for the user.
In conclusion, by adopting the strong-encryption anti-counterfeiting anti-channel conflict commodity code with the structure and the manufacturing method thereof, the sequence code is further encrypted through the check code on the basis of the combination encryption of the existing check code and the sequence code, and finally, the anti-counterfeiting of the commodity code is improved to a new height by using a 3DES encryption mode, so that the anti-counterfeiting anti-channel conflict capability is obviously improved.
The above is a specific embodiment of the present invention, but the scope of the present invention should not be limited thereto. Any changes or substitutions that can be easily made by those skilled in the art within the technical scope of the present invention are included in the protection scope of the present invention, and therefore, the protection scope of the present invention is subject to the protection scope defined by the appended claims.
