Anti-fake method of recording carrying medium self character

Abstract

The invention discloses a fake defend method that includes the following steps: gaining carrying medium self feather information data and recording on carrying medium itself; comparing the self feather information on carrying medium with gained information to take fake defend identification. The benefit of the invention is that: it could realize identification without altering the label, chip, or coating layer contained by bearing medium, and need not to be supported by database. It is a very effective fake defend method in different industry.

Description

technical field [0001] The invention relates to an image processing, encoding and identification technology in computer information hiding and information anti-counterfeiting, in particular to an anti-counterfeiting method capable of recording the characteristics of the carrying medium itself. Background technique [0002] The anti-counterfeiting technology of valuable certificates and commodities has been widely used at present, and most of them adopt laser holographic anti-counterfeiting technology or information anti-counterfeiting technology. Laser holographic anti-counterfeiting marks and digital anti-counterfeiting marks, or special physical structures or tangible carriers with specific information as identification marks. If there is a mark with a special shape on the product or its packaging, the manufacturing difficulty and cost of this mark are relatively high, and the general manufacturer is unable to make this symbolic part, or entrusts direct processing of such ...

AI Technical Summary

Problems solved by technology

If there is a mark with a special shape on the product or its packaging, the manufacturing difficulty and cost of this mark are relatively high, and the general manufacturer is unable to make this symbolic part, or entrusts direct processing of such a mark for consumers to identify; some Bottled products use special bottle caps or bottle bodies, and print or engrave some patterns or text on the bottle body, such as laser anti-counterfeiting marks. This method also has the disadvantage of being difficult to make, and requires consumers to master certain knowledge. Identification ability can only be identified, which is not conducive to popularization and application

There are also some anti-counterfeiting methods that use the form of image anti-counterfeiting product coding databases. At the same time, multiple query processing platforms need to be established for consumers to query and use. However, storing image files for filing requires a large storage space, which requires large investment and strong professionalism. Promote quickly
