Abstract

The invention discloses an anti-counterfeiting graphic-text information encryption method of a grating based on the movement trend of boundary lattice points. The method comprises: step one, preparingan original image and anti-counterfeiting information; step two, carrying out halftone processing; step three, hiding anti-counterfeiting information; and step four, carrying out image synthesis. According to the invention, the selection range of the original image and the anti-counterfeiting information is large; hiding and extraction are realized in the image; and the hiding effect is good andthe extraction identification capability is high.

Description

technical field [0001] The invention belongs to the field of grating anti-counterfeiting technology, and in particular relates to a method for encrypting grating anti-counterfeiting graphic information based on the movement trend of border dots. Background technique [0002] At present, most of the main printing anti-counterfeiting technologies are based on high-precision equipment and special materials. The cost of printing anti-counterfeiting is relatively high, and once the materials and equipment used for printing anti-counterfeiting are obtained, they will be copied in large numbers, thus losing anti-counterfeiting effect. Images and texts that need to be printed and reproduced are usually output through halftone screening. The anti-counterfeiting technology based on moiré is a kind of anti-counterfeiting technology based on the current printing anti-counterfeiting technology and the production conditions of ordinary printing enterprises. Small laziness, simple anti-co...
