A self-encrypting and self-verifying two-dimensional code encoding and decoding method

Abstract

The invention discloses a self-encrypting and self-verifying two-dimensional code encoding and decoding method, in which a record is randomly selected from the data record table corresponding to the currently used key batch number, and the record contains a salt and a key; the salt Concatenate the serial number of the product into a string, use the key to encrypt through the symmetric key algorithm, and obtain the ciphertext; concatenate the key batch number, salt and ciphertext into a string as a parameter; use the given address and parameter Combined, a Url is obtained as the required QR code information encoding. The invention can realize self-encryption and self-verification encoding and decoding of two-dimensional code information, so that the two-dimensional code information is difficult to forge, and can also directly judge whether the two-dimensional code is forged according to the two-dimensional code information.

Description

technical field [0001] The invention relates to the fields of information security and automatic identification, in particular to a self-encrypting and self-verifying two-dimensional code encoding and decoding method. Background technique [0002] Since two-dimensional codes can represent rich information and are easy to use, especially with the popularity of mobile smart terminals, two-dimensional code scanning has become a widely used method. Some companies print a unique QR code on each product to achieve product authenticity identification, product tracking, marketing activities and other purposes. Two-dimensional code technology is to encode the two-dimensional code information represented by a string to generate a scannable two-dimensional code. Generally, open technologies such as QR codes are used, which do not have encryption features and can be easily scanned by any code-scanning software. Reading, so that the QR code on the product is easy to be forged. [0003]...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the two-dimensional code printed on the product is easy to be forged, a two-dimensional code code decoding method capable of self-encryption and decryption is proposed, which can realize self-encryption and self-verification coding of the two-dimensional code information, so that the two-dimensional code The information is difficult to forge, and it is also possible to directly judge whether the QR code is fake based on the QR code information
