Combined anti-counterfeiting mark, and generation method and generation device of combined anti-counterfeiting mark

Abstract

The invention provides a combined anti-counterfeiting mark which comprises a two-dimensional code, a blank space and a dot chart, wherein the two-dimensional code, the blank space and the dot chart are arranged in the same plane. The generation method of the combined anti-counterfeiting mark comprises the steps of obtaining a two-dimensional code pattern which is converted by plaintext information and ciphertext information and has the blank space where the dot chart is to be embedded through a two-dimensional code generator, generating a dot chart pattern with the area not greater than that of the blank space through a dot chart generator, and superimposing the dot chart pattern on the blank space in the two-dimensional code pattern. The generation device of the combined anti-counterfeiting mark comprises the two-dimensional code generator, a dot chart ID (Identity) database, a dot chart pattern generator and a merging device. The combined anti-counterfeiting mark is formed by combining the two-dimensional code and the dot chart; information bonded with the anti-counterfeiting mark cannot be acquired even if the anti-counterfeiting mark is copied by a counterfeiter; and the anti-counterfeiting mark has high-grade anti-counterfeiting performance.

Description

technical field [0001] The invention relates to an anti-counterfeiting mark, in particular to a combined anti-counterfeiting mark, its generating method and generating device. Background technique [0002] Through the two-dimensional code anti-counterfeiting system, the encrypted two-dimensional code product information can be generated one by one corresponding to the product, and the two-dimensional code can be printed or labeled on the product packaging, and the user only needs to use the designated two-dimensional code anti-counterfeiting system or mobile phone software for decoding inspection , you can know a series of authentic safety information of the product, so as to achieve the role of rest assured purchase and supervision of counterfeiting. [0003] At present, because the two-dimensional codes of many products are directly exposed, or after the user's anti-counterfeiting verification is completed, the two-dimensional codes still reside on the product packaging. ...
