Printed anti-false product and method with self authentication information

Abstract

Information carrier is printed or pressed with points, lines, graphics, texts or combination of them, which not only has the only characteristic information, but also has information recorded with characteristic information (namely self-certification information). The method includes: printing points, lines, graphics, texts or combination of them on the information carrier, using an image acquisition instrument to read related characteristic information such as microscopic veins, tablet configuration, gaps surrounded by flaws or veins presented by printing ink or dry toner inside the image acquisition instrument, converting the characteristic information into another information expression mode, namely self-certification information, and denotes on the pressed points, lines, graphics, texts or combination of them on a same information carrier; when identification is required, the characteristic information and self-certification information on the anti-counterfeiting products can be read by the image acquisition instrument, performing internal conversion according to the regulation, and then judging whether the two information is coincident in artificial or automatic mode, if coincident, the characteristic information is true, otherwise it is false. The invention has advantages of low cost, capability of large-lot production, capability of easily and accurately identifying, and application in all fields. The counterfeiters can not effectively imitate.

Description

Technical field: [0001] The invention relates to a commodity authenticity identification technology, and relates to a marked product and an anti-counterfeit method for identifying the authenticity of commodities. Background technique: [0002] Counterfeit and shoddy products are the second largest public hazard in the world after drugs. In order to combat counterfeiting, countries around the world have developed various anti-counterfeiting technology products, such as: anti-counterfeiting paper, anti-counterfeiting ink, special printing, laser holographic anti-counterfeiting, network information anti-counterfeiting, microelectronic chip anti-counterfeiting, etc. It has played a certain anti-counterfeiting role during the period, but with the passage of time, the progress and diffusion of technology have also exposed some unsatisfactory places. In summary, the main problems are: easy to imitate, difficult to identify or high requirements for use , high cost, etc., have reduc...

Problems solved by technology

In order to combat counterfeiting, countries around the world have developed various anti-counterfeiting technology products, such as: anti-counterfeiting paper, anti-counterfeiting ink, special printing, laser holographic anti-counterfeiting, network information anti-counterfeiting, microelectronic chip anti-counterfeiting, etc. It has played a certain anti-counterfeiting role during the period, but with the passage of time, the progress and diffusion of technology have also exposed some unsatisfactory places. In summary, the main problems are: easy to imitate, difficult to identify or high requirements for use , high cost, etc., which reduce the performance and effect of anti-counterfeiting to varying degrees, and some of them themselves have become the object of counterfeiting, failing to achieve the desired anti-counterfeiting and anti-counterfeiting effect
