Embodiment Construction

[0042] A digital anti-counterfeiting method based on chaotic cipher encryption, including two steps of coding and query verification, the specific steps are as follows:

[0043] (1) coding

[0044] The first step is to set a unique 14-digit identity code for each product (the first 4 digits represent the manufacturer code and product code, the 5th to 10th digits represent the production date of the product, and the last 4 digits represent the date of production of the product on a certain assembly line. production serial number); present embodiment is 43211103091025 according to information such as manufacturer's code of commodity, commodity code, production date and production serial number, and the unique identity code of certain commodity is represented as S 13 S 12 S 11 S 10 S 9 S 8 S 7 S 6 S 5 S 4 S 3 S 2 S 1 S 0 .

[0045] In the second step, an 8-digit identity integration code is first formed from the commodity identity code; then, the Cubic-Henon composi...

Abstract

The invention discloses a digital anti-counterfeiting method based on chaos password encryption, which comprises a code making step and an inquiring and verifying step. Double-labeled double codes, namely a security code and a verification code, which can be automatically separated after the consumption are generated by using a chaos password encryption algorithm; a user can inquire many times in different inquiry ways; bidirectional verification is adopted for checking the authenticity of goods, that is to say, a digital anti-counterfeiting center verifies the authenticity of the goods according to the security code sent by a consumer, and the consumer can simultaneously identify the authenticity of the goods and the anti-counterfeiting center according to the verification code returned by the anti-counterfeiting center. The digital anti-counterfeiting method disclosed by the invention has the characteristics of high anti-counterfeiting security, wide application range, resource saving and the like; the method is convenient for carrying out large-scale anti-falsifying census, and can block loopholes on fakes made by means of recycled packing materials or by enterprise internal staff and dealers who take advantages of the positions.

Description

technical field [0001] The invention relates to a digital anti-counterfeiting method for commodities, in particular to a digital anti-counterfeiting method based on chaotic cipher encryption. Background technique [0002] In today's society, commodity counterfeiting has increasingly become a serious problem in the global economic field. It not only greatly damages the vital interests of manufacturers and consumers, disrupts market order, but also brings extremely bad effects on brand building and maintaining social stability. Impact. The application of digital anti-counterfeiting technology can prevent and reduce the occurrence of counterfeit and shoddy goods to a certain extent. [0003] Digital anti-counterfeiting technology involves multiple interdisciplinary subjects such as cryptography and information security, information and signal processing, communication engineering, and computer network. Anti-counterfeiting digital database, consumers "access" the database, que...
