Code fingerprint anti-counterfeiting method

Abstract

A code fingerprint anti-counterfeiting method provided by the present invention includes establishing a code fingerprint database, establishing a code fingerprint of a product to be tested, and retrieving and verifying; establishing a code fingerprint database includes extracting local feature points of a mark area image; Local feature points, the remaining local feature points form a significant local feature point map; obtain block detailed feature vectors according to the significant local feature point map; establish key area feature codes based on the significant local feature point map and block detailed feature vectors fingerprint. The above code fingerprint anti-counterfeiting method collects the image of the commodity logo area on the optical device to contain the difference in printing characteristics, and after processing it through a certain method, a uniquely identifiable code fingerprint is established and stored in the code fingerprint database. By collecting the corresponding image of the commodity to be tested The image of the marked area can be used to determine whether it has a unique code fingerprint in the code fingerprint library. The code fingerprint of this code fingerprint anti-counterfeiting method cannot be deciphered and copied, which can prevent counterfeiters from being prevented.

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...
