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 req

Embodiment Construction

[0020] The carrying medium used in the present invention can be ordinary paper, plastic, textiles and other materials. Even if these materials are produced in the same environment, the texture, spots, or flaws, fibers, etc. of the carrying medium are unique, just like human fingerprints Same. We refer to this unique characteristic of the texture, spots, or defects, fibers, etc. of the carrier medium as "features".

[0021] The following is an example to introduce in detail the principle of writing information containing its own characteristics on a certain bearing medium, and the image information of different bearing mediums is different. Such as figure 1 As shown, the acquisition of the characteristic information data of the carrying medium itself, and recording the obtained characteristic information data of the carrying medium itself on the carrying medium, includes the following steps; obtaining the characteristics of the carrying medium itself by an instrument such as a...

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 ...
