Abstract

The invention provides a code fingerprint anti-counterfeiting method. The method comprises a code fingerprint database establishment step, a to-be-tested commodity code fingerprint establishment stepand a retrieval verification step, and further comprises a mark area image standardization preprocessing step after the mark area image is acquired, so that the mark area image has standardized shape,size and shape stretching conversion. According to the code fingerprint anti-counterfeiting method, the commodity sign area image acquired on the optical equipment contains the printing characteristic difference. After being processed by a certain method, the code fingerprints with unique identifiability are established and stored in a code fingerprint library. Whether the commodity to be detected has a unique code fingerprint in the code fingerprint library can be judged by collecting the corresponding mark area image of the commodity to be detected, if the commodity has the corresponding code fingerprint, the commodity can be judged to be authentic, and if the commodity does not have the corresponding code fingerprint, the commodity can be judged to be false. Code fingerprints of the code fingerprint anti-counterfeiting method cannot be decoded and copied, and prevention of counterfeiters can be completely eradicated.

Description

technical field

[0001] The invention relates to the technical field of commodity anti-counterfeiting, in particular to a code fingerprint anti-counterfeiting method. Background technique

[0002] With the development of the market economy, there are more and more counterfeit goods on the market, and people are hard to guard against. Counterfeit and shoddy goods have become the second largest public hazard in the world after drugs.

[0003] In order to combat counterfeiting, countries around the world have developed various anti-counterfeiting technologies, such as anti-counterfeiting paper, anti-counterfeiting ink, special printing, security seal, watermark, laser holographic anti-counterfeiting, commodity bar code, microelectronic chip, radio frequency (Radio Frequency Identification, RFID) electronic tags, two-dimensional codes and other anti-counterfeiting technologies. However, these traditional anti-counterfeiting technologies cannot really prevent counterfeiting and e...
