Description

A kind of item tracing anti-counterfeiting encryption coding method

technical field

The invention relates to a data encryption method, which is applied to the technical field of article anti-counterfeiting, in particular to an article traceable anti-counterfeiting coding method with high decryption difficulty, strong safety performance and small calculation amount. the

Background technique

Due to the rise of the Internet of Things, RFID has become one of the ten hottest developing industries in the 21st century. In the radio frequency identification industry, the largest share is the RFID electronic tag pasted on the item, and the most valuable part of the RFID electronic tag is the item code. The item code must be unique, safe, reliable, and non-replicable in order to truly protect the genuine product from being counterfeited, avoid and reduce economic losses, and fundamentally protect the interests of consumers. In the prior art, the goal of the article coding method is relatively single, which can only realize the anti-counterfeiting function of the enterprise, and the structure of the coding method is relatively simple, and the counterfeiter can easily decode it smoothly, and produce products with the same product number as the genuine product. Counterfeit products have brought inconvenience to consumers' safe shopping, and also caused great economic losses to enterprises. For the occurrence of the above problems, the prior art does not have a good solution, which brings troubles to the work in this field. the

Contents of the invention

The present invention aims to solve the technical problems of single object coding, simple method and large amount of calculation. The utility model designs an anti-counterfeiting coding method for article traceability, which adopts the method of scrambling the data cycle alternately, exchanging the bit sequence of the data, and verifying the effectiveness. way to ensure the security and legality of data. the

The technical solution adopted by the present invention for realizing the purpose of the invention is an article traceability anti-counterfeiting coding method, which is implemented in the database of the network server with the help of a computer and supporting software management programs. The above-mentioned anti-counterfeiting coding method is to classify global articles Number, and store the number in the database of the network server, based on the standard data encryption algorithm, with the help of the memory in the computer and the supporting encryption algorithm, first encrypt the classification number and generate a verification code, and then encrypt the verification code, Finally, 16-bit ASII code characters are generated and written into the electronic label of the item or made into a barcode and pasted on the product, and stored in the database of the network server. the

The beneficial effects of the present invention are: the encoding method adopts a double encryption method in which the classification number is encrypted to generate a verification code, and then the verification code is encrypted through a six-layer encryption algorithm and a one-layer verification algorithm, thereby ensuring the security of the data Uniqueness, uniqueness and non-reproducibility increase the difficulty of decryption. the

Detailed ways

When the present invention is implemented in practice, it is an article traceability anti-counterfeiting coding method, which is implemented in the database of the network server by means of a computer and a supporting software management program. The above-mentioned anti-counterfeiting coding method is to classify and number global articles, and Stored in the database of the network server, based on the standard data encryption algorithm, with the help of the memory in the computer and the supporting encryption algorithm, first encrypt the classification number and generate a verification code, then encrypt the verification code, and finally generate a 16-bit ASII The code characters are written into the electronic label of the item or made into a barcode and pasted on the product, and stored in the database of the network server. the

The above specific steps for encrypting the classification number are:

A. Carry out rolling encryption calculation on the above numbers with the help of 64-bit polynomial cyclic redundancy check algorithm, and store the calculation results in the computer memory;

B. Carry out standard encryption calculations on the 64-bit data output from the 64-bit polynomial rolling encryption calculation, and store the calculation results in the computer memory;

C. Use the data interleaving encryption algorithm for the data output by the encryption standard calculation, change the position of the sequentially allocated data, distribute it, and store the calculation result in the computer memory;

The specific steps for encrypting the verification code above are:

D. Carry out 16-bit polynomial cyclic redundancy code check calculation on the data output by data interleaving encryption calculation, output 16-bit verification code, and store the calculation result in the computer memory;

E. Carry out standard encryption calculation on the 16-digit verification code, and store the calculation result in the computer memory;

F. Perform data interleaving and encryption calculation on the data after the encryption standard calculation, change the data location, and store the calculation result in the database of the network server. the

The implementation of the above-mentioned article traceability anti-counterfeiting coding method is completed on the server of the data center of the website, and the result of the operation is saved in the database system of the server. When the enterprise wants to use these codes, it can directly call through the network to transfer the traceability of the anti-counterfeiting code It is printed on the trademark of the item, and at the same time, the data is written into the RFID electronic tag to serve the data acquisition system in the Internet of Things. the

16ASII code characters can be made into a barcode and pasted on the product, or directly printed on the product trademark. In order to achieve the purpose of item traceability, the content of this code must be written on the RFID electronic tag. During the circulation of items, the collection system can collect the contents of RFID electronic tags and determine the circulation path of the items. By querying the platform, consumers can trace the source of the item and identify the authenticity of the item. the
