Commodity anti-counterfeiting verification method, commodity anti-counterfeiting verification system, and bar code scanning device

Abstract

The invention is suitable for the commodity anti-counterfeiting verification field, and provides a commodity anti-counterfeiting verification method, a commodity anti-counterfeiting verification system, and a bar code scanning device. The commodity anti-counterfeiting method comprises steps that according to a space geometric relation among various characteristic points in surface characteristic information, the surface characteristic information is reconstructed into a plurality of two-dimensional or three-dimensional anti-counterfeiting images in a digital domain, and an anti-counterfeiting digital image set comprising a plurality of anti-counterfeiting digital images is generated; a commodity bar code database is established, and bar code information and the anti-counterfeiting digital image set are stored; in the commodity bar code database, an association relation between the bar code information of each commodity and the anti-counterfeiting digital image set is established. By adopting the contact-type scanning of the bar codes of the commodities, the anti-counterfeiting digital images corresponding to the bar codes of the commodities are acquired, and the anti-counterfeiting function of the commodities is realized by using the digital images of the bar codes of the commodities.

Description

technical field [0001] The invention belongs to the field of commodity anti-counterfeiting verification, and in particular relates to a commodity anti-counterfeiting and verification method and system and a barcode scanning device. Background technique [0002] Commodity barcodes are mainly used to identify information such as the country of manufacture, manufacturer, commodity name, production date, commodity category, etc., and are widely used in various commodity circulation fields. Some specially encrypted commodity barcodes also have anti-counterfeiting functions. Through the decryption means corresponding to the encryption means, the encrypted barcodes can be decrypted to verify the authenticity of the goods. [0003] However, the anti-counterfeiting barcodes currently on the market all use special anti-counterfeiting coding rules to encrypt the barcodes. Once the anti-counterfeiting coding rules are cracked, all products that apply the anti-counterfeiting coding rules...

Problems solved by technology

[0003] However, the anti-counterfeiting barcodes currently on the market all use special anti-counterfeiting coding rules to encrypt the barcodes. Once the anti-counterfeiting coding rules are cracked, all products that apply the anti-counterfeiting coding rules for anti-counterfeiting coding will lose their anti-counterfeiting functions. It is very easy to be counterfeited by criminals, causing huge economic losses
