Application of novel anti-counterfeiting material in commodity anti-counterfeiting, currency anti-counterfeiting, and bank card counterfeiting

Abstract

Previous anti-counterfeiting materials have a fatal defect that duplication is difficult to prevent. No matter what kind of material we adopt to make the mark, no matter how complex the information isencrypted, the copying can be always realized. The problem of copy prevention cannot be fundamentally solved only from the aspects of material science and cryptography. For this reason, one type of new anti-counterfeiting material (irregular material) can be adopted, and the novel anti-counterfeiting material contains a lot of information so that the novel anti-counterfeiting material is difficult to copy completely. During verification, only a specific position needs to be checked, and the related information amount is small so that the operation is easy. Since the data volume is large, if the checking position is not known, even if an enemy steals the irregular material, a correct checking result cannot be obtained, and the verification cannot be passed. The anti-counterfeiting materialnot only can be used for counterfeiting prevention of commodities, but also can be used for manufacturing currencies, bank cards, identity documents and the like. The currency and data are not easy to lose and are much safer than the conventional electronic currency. The identity document is the most advanced in the offline identity verification technology.

Description

[0001] This application is a divisional application, the original application number is 201711254446.7, the name is "Application of New Anti-counterfeiting Materials in Anti-counterfeiting Payment and Currency Anti-counterfeiting, Bank Cards, etc.", and the application date is November 27, 2017. [0002] The first office action notice of the original application (issued on April 26, 2020) pointed out that the claims of the original application did not conform to the principle of unity, so part of them (rights 4 and 5) were applied for separately, and some of the claims related to the Content irrelevant to the new topic is deleted. technical field [0003] The present invention relates to commodity anti-counterfeiting technology, electronic payment technology, currency anti-counterfeiting, bank card anti-counterfeiting and identification technology. More specifically, it is the technology of currency anti-counterfeiting, bank card anti-counterfeiting and identity authentication...

AI Technical Summary

Problems solved by technology

The cost of anti-counterfeiting in packaging is high, but packaging is still easy to counterfeit

Although the cost of the previous anti-counterfeiting code technology is low, it is easier to counterfeit

[0005] In the past, in many cases, the anti-counterfeiting code was calculated based on the serial number and other data of the product through a specific encryption algorithm. This does not require a large database and the cost is low. However, if the opponent spends a long time, after many times operation, it is possible to crack

In the past, many insiders of anti-counterfeiting code companies leaked encryption algorithms and keys.
