Compound two-dimensional code and identifying system thereof

Abstract

The invention provides a compound two-dimensional code and an identifying system thereof. A two-dimensional code is embedded in the traditional two-dimensional code carrier as a watermark two-dimensional code to form the novel compound two-dimensional code. Compared with the traditional two-dimensional code technologies, the compound two-dimensional code and the identifying system have the advantages that specific people can be read and identified by the aid of two-dimensional code technologies; the watermark two-dimensional code is arranged inside the compound two-dimensional code and can be used as confidential anti-counterfeiting information of the traditional two-dimensional code, and accordingly the safety and the reliability of the existing two-dimensional code can be improved; information which can be stored in the existing two-dimensional code can be doubled, and accordingly the information storage capacity of the two-dimensional code can be improved; the attack resistance of the two-dimensional code can be improved.

Description

technical field [0001] The invention relates to a compound two-dimensional code and its identification system. Background technique [0002] The two-dimensional code has the advantages of large information capacity, wide coding range, strong fault tolerance, high decoding reliability, encryption measures can be introduced, low cost, easy to manufacture, and durable. It has applications in various aspects nowadays, such as information acquisition, website redirection, advertisement push, mobile e-commerce, anti-counterfeiting traceability, preferential promotion, membership management, mobile payment, etc. Become an indispensable tool in people's daily life. [0003] At present, the two-dimensional code technology adopts the indiscriminate scanning technology, and any object can scan the two-dimensional code through other tools such as mobile phones to identify the information in it. However, this kind of two-dimensional code technology has certain security risks as an info...

AI Technical Summary

Problems solved by technology

However, this kind of two-dimensional code technology has certain security risks as an information transmission medium, especially for areas involving user information security, such as property security, personal private information, etc.

In addition, although the current traditional two-dimensional code technology itself has a certain security and anti-counterfeiting performance, the method used is only a simple XOR method, which cannot be regarded as a strict security and anti-counterfeiting technology.
