A light and dark code anti-counterfeiting label and its anti-counterfeiting method

Abstract

The invention provides a plain and secret code type anti-fake label and an anti-fake method thereof. The plain and secret code type anti-fake label comprises a plain code area and a secret code area, wherein the plain code area comprises a multi-dimensional code, and the multi-dimensional code is obtained by combining a first anti-fake code and a source tracing code; the secret code area comprises a piece of secret code area anti-fake information, and the secret code area anti-fake information is obtained by conducting redundant operation on a second anti-fake code. During recognition, a consumer obtains the multi-dimensional code and the secret code area anti-fake information, anti-fake verification of the plain and secret code type anti-fake label is achieved through combination of the first anti-fake code and the second anti-fake code which are obtained through the multi-dimensional code and the secret code area anti-fake information respectively, in this way, even if a reading device on the market reads the relevant multi-dimensional code, specific information contained in plain and secret anti-fake codes can not be guessed, the multi-dimensional code in the plain code area is effectively prevented from being directly exposed outside just as a traditional two-dimensional code with the with the core plaintext directly exposed at present, anti-fake safety performance is greatly improved, and the probability that the label is decoded is reduced.

Description

technical field [0001] The invention relates to anti-counterfeiting technology, in particular to a multiple anti-counterfeiting technology based on a light and dark code anti-counterfeiting label and an anti-counterfeiting method based on the light and dark code anti-counterfeiting label. Background technique [0002] In the prior art, the two-dimensional code anti-counterfeiting traceability technology refers to the use of two-dimensional code technology and wireless communication network technology, using the two-dimensional code as the information carrier, to track, collect, and manage the information of each commodity, so as to realize one code for one product , so as to establish a commodity information management data chain and a supervision system for the entire circulation process. In the process of use, you only need to easily scan the code through the reading software installed in the mobile terminal, and you can conveniently query the product information in real t...

Problems solved by technology

[0003] However, there are still many problems in the current anti-counterfeiting technology: for example, the two-dimensional code itself is not used to prevent copying and reading, it is easy to be collected, and there are many kinds of two-dimensional code collection equipment on the market, the core data of related products It is easy to be read by other illegal software, thereby reducing the security of anti-counterfeiting; moreover, the QR code itself is exposed in the market, and usually has been checked by non-purchasers for anti-counterfeiting, causing buyers to directly conduct secondary anti-counterfeiting inquiries. This reduces the authenticity of the product; finally, because most of the digital information of the traditional two-dimensional code on the market is in plain text format, the two-dimensional code itself does not have "anti-counterfeiting", and is directly exposed to the outside after being read by the scanning software, thus Easy to be exhaustively deciphered by hackers or other illegal personnel
