Anti-counterfeiting method based on non-contact IC card

Abstract

The present invention discloses a false proof method of non-contact IC card, which includes anti-counterfeit mark information carrier, cipher key composite process, digital signing process and real and false recognizing process; the present invention is suitable for one-time operation non-contact IC card integrated false proof objects as false proof of anti-counterfeit mark data media, can discriminate false proof objects, false proof objects producer, false proof trade company, identity of non-contact IC card and genuine-fake; can discriminate all imitation behavior of anti-counterfeit mark information and false proof objects; the present invention is specially adapted to false proof such as check wine and cigarette, ID card, diploma, bank card, license plate, industrial products, rare medicine, etc.

Description

Technical field [0001] The invention relates to an anti-counterfeiting method using a non-contact IC card as an anti-counterfeiting identification information carrier, and also relates to the production process, key combination process, digital signature process and authenticity identification process of the one-time anti-counterfeiting identification body of the anti-counterfeiting method. Background technique [0002] There are many technologies and methods used in anti-counterfeiting fields such as commodities, certificates, and license plates. Laser anti-counterfeiting and digital anti-counterfeiting are mainly used in the market, but the current anti-counterfeiting technologies generally have the following problems: [0003] 1. No matter how complicated the product carrier, package and its production process are, with today’s manufacturing technology, counterfeiters can quickly imitate or reuse the product carrier and package; [0004] 2. Commodity anti-counterfeiting m...

AI Technical Summary

Problems solved by technology

[0004] 2. Commodity anti-counterfeiting marks are also easy to be imitated and reused by counterfeiting gangs;

[0005] 3. Unable to identify merchants who are shoddy;

[0006] 4. In the process of commodity circulation, the authenticity of the commodity cannot be identified or the authenticity identification is restricted by various conditions;

[0007] 5. The control right of product anti-counterfeiting is controlled by anti-counterfeiting merchants, and there are a few anti-counterfeiting merchants or leakers anti-counterfeiting and counterfeiting phenomenon;

[0008] 6. Commodity authenticity identification depends on human sensory experience or simple tools, and the identification is cumbersome. For most consumers, the authenticity of commodities is unclear;

[0009] 7. Commodity authenticity identification requires the support of various networks and databases, which brings a lot of inconvenience to commodity manufacturers and consumers, and the cost and effect of anti-counterfeiting are also questioned, such as information network anti-counterfeiting technology, digital (code) anti-counterfeiting technology, etc.;

Therefore, in the original invention, more equipment resources are occupied. For example, at least 1024*m bit capacity space will be occupied in the anti-counterfeiting identifier. The anti-counterfeiting identifier is relatively large in size, high in cost, and poor in portability.

[0013] 2. In the national invention patent "Password Anti-Counterfeiting System and Its Encryption and Identification Method", the number of public keys in its public key function library is m, and when combining public keys, r public keys are randomly selected to form anti-counterfeiting object production The public key group and the corresponding private key group of the user, the value of r should not be too large, even if it is 3, when using the combined public key group and private key group for encryption and decryption, the speed is relatively slow

[0014] 3. In the national invention patent "Password Anti-Counterfeiting System and Its Encryption and Identification Method", the number of key combinations is relatively small, only C m r One, if m and r are large, the key will take up too much capacity for storage, resulting in high cost and large size of the anti-counterfeit identifier; at the same time, the speed of encryption and decryption will be greatly delayed, affecting the authenticity of the product. efficiency
