Methods for preparing and identifying continuous-real-object anti-counterfeit label based on image contrast

Abstract

The invention discloses methods for preparing and identifying a continuous-real-object anti-counterfeit label based on image contrast. The preparing method comprises the steps of printing an anti-counterfeit serial number on blank label paper, preparing an anti-counterfeit real-object pattern in a corresponding area of the label paper, and saving a photographed picture in an inquiry website in a manner that the photographed picture corresponds to the anti-counterfeit serial number. The identifying method comprises the steps of photographing the anti-counterfeit label by using a camera of a mobile phone or logging on the inquiry website and inputting serial number codes on the anti-counterfeit label, comparing whether a real picture and a continuous real object on the anti-counterfeit label of a commodity are consistent or not, and further judging whether the commodity is genuine or not through combining historical inquiry record information returned from a database of the inquiry website if the real picture and the continuous real object on the anti-counterfeit label of the commodity are consistent. According to the method, a plurality of continuous real objects are adopted as anti-counterfeit information carriers; the real-object information carriers are non-print randomly stuck or brushed real objects, e.g. random shape/color paper, random real object lines and the like; and real-object signs can be as complicated as possible, so that the cost of copying and imitating for other people can be increased.

Description

technical field [0001] The invention relates to a label-based anti-counterfeiting technology, in particular to a method for preparing and identifying continuous physical anti-counterfeiting labels based on image comparison. Background technique [0002] Anti-counterfeiting refers to a measure taken to prevent imitation, duplication or counterfeiting and sales of other people's products without the permission of the trademark owner by means of counterfeiting. Anti-counterfeiting products on the market can be divided into five generations from the perspective of technical features and functional evolution: the first generation is represented by laser labels; the second generation is mainly query-type digital anti-counterfeiting label products; the third The first-generation products are mainly textured anti-counterfeiting labels; the fourth-generation products mainly use security thread anti-counterfeiting paper technology, including various product anti-counterfeiting instruc...
