Abstract
The invention discloses an unlocking anti-counterfeiting method which is a dual-branch unlocking anti-counterfeiting method using an unlocking diagram to unlock different anti-counterfeiting information. The method is good in information hiding performance, clear in printing, wide in application range and difficult to imitate and improves hiding performance and anti-counterfeiting performance of an unlocking anti-counterfeiting technology.
Description
Technical field
The present invention relates to field of anti-counterfeit technology, be specifically related to the unlocking anti-fake method.
Background technology
The unlocking anti-counterfeit technology is to utilize the principle of interference of light, hide the security element (as information such as word, images) embedded by the variation of lines, after adding the diaphragm of unblanking of special facture, adjust slightly a kind of anti-counterfeiting technology that the angle of the diaphragm of unblanking can make to hide Info and display.The diaphragm of unblanking is according to forming with security element the film that the parameter (as the big or small spacing of line or net) of part is made and exported, be cut into the film block that suitable size is easy to carry about with one in practicality.During use, the diaphragm of unblanking is added to the pattern position hidden Info, when normal vision is observed, can't see the security element of these embeddings, by just seeing after the diaphragm of unblanking at all.But it is that lock is reopened in site one that current unlocking anti-counterfeit technology generally just can only demonstrate a figure, easily is cracked.Although adopt lines can accomplish that sixfold unblanks, after the graphic printing that adopts lines to form, the color is too dark, application surface is narrow, more easily is imitated.
Summary of the invention
The object of the invention is to disclose the unlocking anti-fake method, solved and adopted site can only realize a heavy problem.
In the present invention, figure refers to the polar plot consisted of the exterior contour lines; Image is the bitmap consisted of pixel-matrix; Color range means the standard of index of brightness of image power, and the brightest now color range of white is 0, and the black now color range that do not work most is 100%.
