Embodiment Construction

[0130] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are illustrative rather than limiting.

[0131] figure 1 It is a flow chart of a novel anti-counterfeiting code generation method.

[0132] Such as figure 1 Shown in: the generation method of novel anti-counterfeiting code is constituted by three steps.

[0133] First, in the step of reading the anti-counterfeit code, read the encrypted random anti-counterfeit code of the computer, or the anti-counterfeit code formed according to the attribute of the product, the date of manufacture, the place of manufacture, the place of sale and the like. Using these naturally formed or artificially given codes can be used as a basis for identifying the authenticity of commodities.

[0134] Secondly, in the anti-counterfeiting code transforming step, the above-mentioned read anti-counterfeiting numbers are transformed i...

Abstract

The invention relates to a method for assigning anti-counterfeiting codes using lasers in the field of information processing. It can automatically assign invisible variable information to the product on the product packaging production line, and can solve the problem of variable information being copied in batches by high-precision scanning and batch copying of high-precision scanning matting. Compared with the traditional two-dimensional barcode technology, it has the characteristics of preventing batch copying and invisibility. Compared with the traditional labeling method, the solution provided by the present invention has the characteristics of low cost, fast processing speed and high online linearity. It can be widely used in the Internet of Things to assign product identities to any product, as well as the application of network interfaces, as well as applications in the fields of product anti-counterfeiting and product traceability.

Description

technical field [0001] The invention belongs to the field of information processing, in particular to a method for assigning anti-counterfeit codes using lasers. Background technique [0002] With the rapid development of computer information network technology, the Internet of Things technology with code, mobile phone reading and network as the core is developing vigorously with each passing day. [0003] In Japan, as the latest two-dimensional barcode, it is possible to directly record large-capacity sound data, and a patent called dot-matrix code, which uses unlimited combinations of codes distributed in several two-dimensional rectangular lattices, was published: "Optical A reading device for readable two-dimensional barcodes" (Japanese Patent Laid-Open No. 2005-243047). Although the use of this code can directly record the sound on the code, but due to the large volume of sound data, the area of ​​the code is relatively large due to the large volume of sound data. The...
