Description

Technical Field

[0001] The present invention relates to the field of anti-counterfeiting technology, and in particular to a commodity anti-counterfeiting method and terminal. Background Art

[0002] In order to prevent the anti-counterfeiting code from being recognized multiple times, the existing product anti-counterfeiting method adopts the method of only recognizing it once as authentic and recognizing it repeatedly as counterfeit. This makes it impossible for merchants to confirm the authenticity of the goods to consumers before they buy them. Once verified as authentic, consumers must buy the goods, and the goods cannot be authenticated for a second time, which affects secondary sales. This anti-counterfeiting method cannot be used repeatedly.

[0003] In addition, the existing anti-counterfeiting system for some products verifies the authenticity after the products leave the factory, which needs to be done by logging into a website, making a phone call or sending a text message. However, it is difficult for consumers to distinguish the authenticity of the website, phone call or text message background. It is completely dependent on the background. If the background is a fake background, the final identification result is also unreliable. Counterfeiters may use the fake background to pass off the fake as the real thing. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a commodity anti-counterfeiting method and terminal, which can improve the security and reliability of anti-counterfeiting while achieving multiple anti-counterfeiting.

Finally, the product end updates the preset private key based on the authentication result, uses the key technology to jointly sign the product authenticity authentication information, and updates the private key based on the authentication result after obtaining the authentication result. When the product is authenticated again, the updated private key can be used for anti-counterfeiting again, thereby achieving multiple anti-counterfeiting. Moreover, since the private key can be updated in time after the authentication is completed, even if the private key is obtained by the counterfeiter during the anti-counterfeiting process, the private key obtained by the counterfeiter will be invalidated during the next product authenticity authentication, thereby achieving multiple anti-counterfeiting while improving the security and reliability of anti-counterfeiting.

[0120] Specifically, the blockchain end obtains the corresponding basic information of the commodity from the existing block according to the commodity end identifier, such as Figure 5 As shown;

[0121] When a commodity is identified or traded multiple times, the blockchain end will query through the commodity end identifier and obtain multiple blocks corresponding to the commodity. Then, it will search in the order of transaction time to obtain the most recent block. The preset public key in the most recent block is the latest public key. In addition, the multiple blocks corresponding to the commodity can reflect the circulation status of the commodity.

When the product is authenticated again, the updated private key can be used for anti-counterfeiting again, thereby realizing multiple anti-counterfeiting, and because the private key can be updated in time after the authentication is completed, even if the private key is obtained by the counterfeiter during the anti-counterfeiting process, the private key obtained by the counterfeiter will be invalidated during the next product authenticity authentication. In addition, the entire anti-counterfeiting process is realized by the cooperation of the three ends, which can effectively avoid the anti-counterfeiting information of one end being stolen, resulting in a decrease in the security of the entire anti-counterfeiting process, thereby realizing multiple anti-counterfeiting while improving the security and reliability of anti-counterfeiting.
