Encrypted three-dimensional code generation and identification method and system

Abstract

The invention relates to a method for generating and identifying an encrypted three-dimensional code. The method comprises a code generating step and an identifying step, the code generation step specifically comprises the following steps: presetting a plurality of user-defined encryption modules and encryption rules; the method comprises the steps of obtaining to-be-coded content, determining a user-defined encryption rule, compiling the to-be-coded content into an unencrypted two-dimensional code matrix, and performing encryption operation according to the selected user-defined encryption rule to generate an encrypted two-dimensional code matrix; drawing a two-dimensional code graph through the encrypted two-dimensional code matrix, and obtaining a background picture to be fused with the two-dimensional code graph to generate an encrypted three-dimensional code; the decoding step specifically comprises the following steps: configuring an encrypted three-dimensional code decryption program containing respective defined encryption rules at a code scanning end; and the code scanning end scans the encrypted three-dimensional code picture to be identified, determines the self-defined encryption rule used by the encrypted three-dimensional code, decrypts the encrypted three-dimensional code through the corresponding decryption rule to obtain an unencrypted two-dimensional code matrix, and decodes the unencrypted two-dimensional code matrix to obtain the code making content.

Description

technical field [0001] The invention relates to an encrypted three-dimensional code generation and recognition method, which belongs to symbol coding and recognition technology and is suitable for high-density symbol coding systems. Background technique [0002] Secret-related units need to strictly implement the confidentiality system, including communication tools, communication networks, etc.; in terms of secret-related confidentiality, take personal business cards as an example, code the personal business card information with a two-dimensional code, and paste the code picture on the bulletin board Or when it is displayed on electronic screens and other publicity means, it is easy to be identified by outsiders with third-party software, or the code map will be flowed out by taking pictures, resulting in the leakage of personnel information of confidential units. Similarly, the confidentiality of important information such as communication URLs and device models is not hi...
