Anti-fake secret mark and anti-fake mark

Abstract

Disclosed is an anti-fake secret mark. Two or more colorless fluorescent patterns are printed on a carrier respectively and are grouped, mutually-associated and colorless images containing digitalized information; secret key-secret key comparison can be performed among digitalized information of different images through the digitalized information of images, read by the reading equipment, comparing successful digitalized information through secret key-secret key, and identity codes can be formed through fixed stipulations or preset algorithms. The anti-fake mark comprises the anti-fake secret mark. Patterns formed by texture material which are distributed randomly are utilized as an anti-fake carrier, so that the anti-fake mark is difficult to copy and counterfeit; the images of the digitalized information in grouped use, so that manufacturing technology is high in difficulty. A common consumer can visually and accurately identity commodities through a cellphone containing the anti-fake identifying function, and the anti-fake secret mark is easy in recognition. Whether the anti-identification mark which can help law executors or identifying experts to quickly identify, so that accuracy and insurance in identifying are realized.

Problems solved by technology

Although the fluorescent anti-counterfeiting mark that emits a single fluorescent color has certain anti-counterfeiting functions and is relatively simple to make, because of this, its anti-counterfeiting guarantee may not last long, and it is easier for counterfeiters to obtain this fluorescent ink through improper means and imitate it.
