Anti-counterfeiting method for printed product based on digital water print technique

Abstract

A method of the printed product fake-prevention bases on the digital watermark technology. Firstly, it chooses an appropriate color edition in the printed images and distills its printed points of network as the original point images. Then it chooses a constant area as the original image which the texture composes. It initializes a blank image as the same as the size and at random produces some points as the seeds which the texture composes in the center of the blank image. In succession, it produces two printed models which can separately represent 0 and 1 by the texture composed technology and the original image as the cyclostyle and utilizes the local search to actualize the asymmetric texture composition of the printed color edition. Finally, it executes the prevented fake information to the binary system order to embed it into the printed image. The invention can offer the effective proof by embedding non-obviously the distilled prevented fake information in the production packing. At the same time, it provides the stronger resisted forged ability and doesn't add the extra prevented fake cost. The consumer can distill the equipment to affirm the real of the production by the corresponding prevented fake information.

Description

technical field [0001] The invention relates to an anti-counterfeiting method for printed products based on digital watermarking technology, which can be used for anti-counterfeiting of printed products such as product packaging and printed handicrafts, and relates to the technical fields of image processing technology, digital watermarking technology and texture synthesis. Background technique [0002] The problem of counterfeit and shoddy products has always been a thorny problem plaguing my country's economic development. No matter countries, enterprises or consumers have suffered heavy losses. In order to solve this problem, the state and enterprises have also invested huge efforts. However, due to the complexity of combating the problem of counterfeit and shoddy products, the effect achieved so far is still very limited. It can be said that the problem of counterfeit and shoddy products will plague my country's economic development for a long time. [0003] For the pr...

Problems solved by technology

However, these technologies are all based on FMS (Frequency Modulated Screening), which means additional difficulties in the embedding and detection process, and the cost is also very high, thus affecting further practical promotion and application
