Code fingerprint anti-counterfeiting method

Abstract

The invention provides a code fingerprint anti-counterfeiting method. The code fingerprint anti-counterfeiting method comprises the following steps: establishing a code fingerprint library, establishing a to-be-tested commodity code fingerprint, and retrieving and verifying; wherein the step of establishing the code fingerprint database comprises the sub-steps of extracting local feature points of the sign area image; removing general locality feature points in the locality feature points, and forming a significant locality feature point graph by the rest locality feature points; acquiring a block detail feature vector according to the salient locality feature point graph; and establishing a key area feature code fingerprint according to the salient locality feature point graph and the block detail feature vector. According to the code fingerprint anti-counterfeiting method, the commodity sign area image acquired on the optical equipment contains the printing characteristic difference; the code fingerprint anti-counterfeiting method has the advantages that the code fingerprint with unique identifiability is established and stored in the code fingerprint library after being processed by a certain method, whether the code fingerprint has the unique code fingerprint in the code fingerprint library or not can be judged by collecting the corresponding mark area image of the to-be-tested commodity, the code fingerprint of the code fingerprint anti-counterfeiting method cannot be decoded and copied, and the counterfeiting of a counterfeiter can be 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...
