Anti-counterfeiting and authenticity-verifying method and system for article

Abstract

The invention discloses an anti-counterfeiting and authenticity-verifying method and system for an article. The method comprises the following steps of: encrypting anti-counterfeiting article information acquired by using a first private key to generate a first signature file, and generating anti-counterfeiting codes according to public key information corresponding to the first signature file and the first private key; and when the article with the generated anti-counterfeiting codes is verified and displayed, acquiring image information of the anti-counterfeiting codes by using image pickup equipment, obtaining the first signature file and the public key information according to the image information, decrypting the first signature file according to the public key information, displaying the decrypted information, and judging the authenticity of the article according to the displayed information. According to the method, when the authenticity of the article is queried, the authenticity of the article can be identified without querying the information database of the article through a mobile phone or short message or in a surfing mode, the query process is convenient, and consumption of communication resources cannot be generated; meanwhile, according to the method of the embodiment, information data of the article do not need to be established and maintained, thus the cost of querying the authenticity of the article is reduced.

Description

technical field [0001] The invention relates to the technical field of digital signature and anti-counterfeiting, and more specifically relates to a method and system for anti-counterfeiting and authenticity verification of articles. Background technique [0002] With the continuous fierce competition in society, all kinds of counterfeiting and counterfeiting behaviors are increasing day by day.

Problems solved by technology

[0004] Although the authenticity information of certificates and products can be inquired through the existing method, since the authenticity information needs to be inquired by means of telephone, short message or Internet, etc., the inquiry process is inconvenient, and the time-consuming of inquiring the authenticity information is relatively long. It will inevitably cause the consumption of communication resources; at the same time, the existing methods need to establish and maintain the information database of the inquired items, which increases the cost of inquiring about the authenticity of the items
