Combined anti-counterfeiting mark based on the same id, and generation method and device

Abstract

The invention provides a combined anti-counterfeiting mark based on the same ID (Identity). The combined anti-counterfeiting mark is composed of a two-dimension code and a dot-matrix graphic; a generation process of each of the two-dimension code and the dot-matrix graphic is a method for extracting the same ID number from an ID number database, and generating the combined anti-counterfeiting mark, and comprises the following steps: converting the ID number extracted from the ID number database, and parameter information, clear text information and cipher text information of the two-dimension code a into the two-dimension code; and generating the dot-matrix graphic smaller than the two-dimension code by the ID number the same as the two-dimension code through a dot-matrix graphic generator. A device for generating the combined anti-counterfeiting mark comprises a two-dimension code generator and the dot-matrix graphic generator. The two-dimension code and the dot-matrix graphic, provided by the invention, have the same ID number, so that the two-dimension code and the dot-matrix graphic have the relevance; the two-dimension code only can be read by special equipment, and the dot-matrix graphic cannot be identified again after being copied and scanned, so that the combined anti-counterfeiting mark has a 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 based on the same ID, and a generating method and 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 ...
