Image and text information hiding and reappearing structure and method based on color balance

Abstract

The invention relates to the pattern making anti-counterfeit technical field, in particular to an image and text information hiding and reappearing structure and method based on color balance. The structure comprises a composite hue layer A and a composite hue layer B, wherein the composite hue layer A and the composite hue layer B are similar hues each of which is formed by combination of at least two tones, the composite hue layer A is filled with tiny geometric pattern layers, the composite hue layer B is filled with pattern layers opposite to the tiny geometric pattern layers, image and text information hiding and reappearing are achieved through the tiny geometric pattern layers and the pattern layers opposite to the tiny geometric pattern layers, and the composite hue layer A and the composite hue layer B are integrated in an embedded mode. Compared with the prior art, the structure and method have the advantages that color information and shape information are integrated through stacking of colors and embedding of shapes instead of being shown directly so that replication with high-precision scanning equipment can be eradiated basically, anti-counterfeit products are harder to copy or recover, and reappearing can also be achieved with special tools to identify the authenticity.

Description

[technical field] [0001] The invention relates to the technical field of plate making anti-counterfeiting, in particular to a structure and method for hiding and reproducing graphic and text information based on color balance. [Background technique] [0002] At present, the plate-making anti-counterfeiting methods applied to graphic and text information hiding are mostly based on shape displacement, undulation, size, thickness, and presence or absence. With continuous improvement, plate-making anti-counterfeiting methods based on small structure or subtle shape changes to hide information have become more and more easy to be copied and restored, and cannot really play the role of anti-counterfeiting and anti-counterfeiting detection. Therefore, there is an urgent need for a hidden mechanism and implementation structure that cannot be correctly separated by scanning equipment and thus cannot obtain correct shape information. [0003] The existing plate-making anti-counterfei...

Problems solved by technology

However, they all have the following disadvantages: the color or shape information used for restoration is directly presented, and the information itself is not hidden; the available information is miniaturized to a certain extent by using the visual limit of the human eye so that it cannot be observed by the naked eye; but will show up on the scanning device
