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 code attaching method for the anti-fake code by using a laser device in the field of information processing. According to the code attaching method, commodities can be automatically subjected to code attaching for hidden variable information on a commodity package production line, and the problems of high-precision scanning batch copying and high-precision scanning image matting batch copying of variable information can be solved. Compared with the conventional bidimensional bar code technology, the code attaching method has the characteristics of prevention of batch copying and hiding. By the introduction of the solution provided by the invention, compared with the conventional labeling method, the code attaching method has the characteristics of low cost, high processing speed and high linear property. The code attaching method can be widely applied to code attaching for the commodity identify of any commodity in the Internet of things and is suitable for application of network interfaces and application in the field of commodity counterfeiting prevention, commodity tracing and the like.

Description

technical field [0001] The invention belongs to the field of information processing, in particular to a method for paying anti-counterfeit codes by using a laser. 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. Th...
