Design and identification system for Dot point set codes

Abstract

The invention discloses a design and identification system of a Dot point set code, comprising: an encoding device used for encoding input data and adding random offset to obtain target encoding information; the code generating device is used for generating positioning information and obtaining a point set code graph based on the positioning information and the coding information; and the decoding device is used for processing the point set code graph to obtain original embedded information. The Dot point set code provided by the invention has the advantages of high concealment, high identification precision, strong error correction capability and secrecy performance, and enables enterprises and detection departments to have more choices for anti-counterfeiting, anti-channeling and traceability requirements.

Description

technical field [0001] The invention belongs to the field of point set codes, in particular to a design and identification system of Dot point set codes. Background technique [0002] With the continuous development of our country's market economy, more and more counterfeit and shoddy products are flooding people's lives, seriously destroying the order of our country's market economy. Traditional anti-counterfeiting labels and QR codes can be easily torn, destroyed or reused, and products cannot be inspected and traced normally, resulting in frequent market counterfeiting and distribution of goods, seriously damaging the rights and interests of creators and consumers. Although the existing anti-counterfeiting technology is constantly being updated, there are loopholes or deficiencies in many technical solutions. Bar codes came out in the 1940s. Because of their fast input speed, high reliability, and low cost, they are widely used in various industries such as food, books, ...

AI Technical Summary

Problems solved by technology

Most of the existing anti-counterfeiting technologies that use two-dimensional codes use two-dimensional codes as the information carrier medium, and use special ink or printing technology to process the two-dimensional codes, so that they cannot be observed by the naked eye under normal circumstances, but can only be seen through Special equipment for identification

Although doing so can prevent the QR code from being maliciously damaged or re-used to a certain extent, its cost is also very high, and consumers cannot use mobile phones to identify it, which greatly limits its practicability
