General anticounterfeiting method and system

Abstract

Using digital signature of manufacturer, the invention discloses general type anti false system of possessing particular treatment process. Built in RFID / smart card tag of goods, the said digital signature is in use for validating truthfulness of the goods. Without need of complex installation and method, the system is only composed of unscrambler and tag. The procedure and method are so designed that manufacturers are allowed to prepare and configure tags by using own digital signature. The invention let purchaser verify truthfulness of goods easily and reliably. Moreover, before the first use, reliability of the unscrambler itself of tag is also checked up.

Description

technical field [0001] The present invention generally relates to a method and system for authenticating a product. In particular, the present invention describes a practical system with a unique process that is easy to configure, easy to use, and very effective and powerful against counterfeiters. Background technique [0002] Counterfeiting of goods is a serious problem these days, especially with the aid of new sophisticated techniques. Counterfeit goods can appear more authentic and come in greater numbers. Counterfeiters deprive manufacturers of brand names that may take years to build. They prey on consumers with fake, low-quality, and sometimes dangerous products such as pharmaceuticals. It is generally accepted that a good anti-counterfeiting system will benefit both the manufacturer and the consumer, and will be most effective if both the manufacturer and the consumer are involved in the anti-counterfeiting process.

AI Technical Summary

Problems solved by technology

However, there are several disadvantages in the existing system

First, except for RFID tags and tag readers, each product requires a unique serial number, which makes it difficult for manufacturers to implement the system for high-volume products

Second, the actual identification is done by the consumer, not the label reader, who has to manually and visually compare the reading to the number printed on the label

Given the large number of different types of goods, this method is difficult for consumers to use, and consumers may become overwhelmed

Third, the existing technology mentions but does not explore the actual use of public key encryption, which will be the core technology of the authentication system, but the existing technology does not provide how the manufacturer distributes the public key to consumers when selling s solution

Furthermore, there is no solution as to how the public key is distributed to consumers at the point of sale

Also, without other safeguards, the existing system is vulnerable and easily rendered ineffective by counterfeiting trademarks, labels and readers
