Two-dimensional code multi-enciphering anti-fake printing method

Abstract

The invention relates to the anti-counterfeiting printing technical field, in particular to a multi-encryption and anti-counterfeiting printing method for a two-dimensional code which is applicable to the two-dimensional code and has encryption requirements on the information of the two-dimensional code, and the multi-encryption and anti-counterfeiting printing method is carried out according to the following steps: (1) original data of the two-dimensional code to be encrypted is input to an encryption system; (2) the encryption system takes out one or a plurality of bits from the original data of the two-dimensional code to carry out a first encryption algorithm calculation, thus obtaining a group of random check codes; (3) the group of random check codes are arranged in the original data of the two-dimensional code, thus generating a group of data containing the random check codes; (4) the obtained data containing the random check codes is carried out a second encryption algorithm calculation, thus generating the dual-encryption data; (5) the obtained dual-encryption data is utilized for generating the dual-encryption two-dimensional code; (6) the dual-encryption two-dimensional code is transmitted to a digital printing system for printing. The method can effectively prevent others from utilizing the existing two-dimensional code reading device to decode the encrypted content, thus obtaining the information in the two-dimensional code and having good confidentiality.

Description

Two-dimensional code multiple encryption anti-counterfeiting printing method technical field The invention relates to the technical field of anti-counterfeiting printing, in particular to a two-dimensional code multi-encrypted anti-counterfeiting printing method, which is suitable for occasions requiring confidentiality of information in the two-dimensional code. Background technique In the prior art, the information in the two-dimensional code is not encrypted, and counterfeiters can read the two-dimensional code as long as they have corresponding two-dimensional reading equipment, so as to obtain the information in the two-dimensional code. In this way, the two-dimensional code cannot be used in some occasions with confidentiality requirements. Contents of the invention The purpose of the present invention is to provide a two-dimensional code multiple encryption anti-counterfeiting printing method, which can effectively prevent others from using the existing two-dimen...
