Abstract

The invention discloses a multilevel information encryption-based mixed two dimensional code comprising a universal code area and a minisize code area; the universal code area comprises a function area and a first coding area, the function area comprises a position detection area used for rapidly detecting an MC code and a first index area used for indexing a decoding sequence of common information, the first coding area is used for storing the common information and correcting an error correcting code for common information loss, and the minisize code area is positioned in the position detection area of the universal code area; the minisize code area comprises a positioning area, a second index area and a second coding area; the positioning area is used for positioning a minisize code, the second index area is used for indexing a decoding sequence of encrypted information, and the second coding area is used for storing important information and correcting an error correcting code for important information loss. Via the multilevel information encryption-based mixed two dimensional code disclosed in a technical solution of the invention, a problem that a conventional two dimensional code provides insufficient information and is poor in information security can be solved.

Description

technical field [0001] The invention belongs to the field of artificial intelligence, in particular to a mixed two-dimensional code based on multi-level information encryption. Background technique [0002] Currently, rectangular two-dimensional codes, especially QR two-dimensional codes, have been widely used. The existing QR two-dimensional code technology can no longer meet the information storage requirements per unit area. The information storage capacity of a version 1 QR code is only 216 bits, which means that in order to store information with a higher amount of data, a higher version must be used, and for the current coding method, this also means that Larger QR code image area. Moreover, the information encryption of existing two-dimensional codes is usually one-time encryption, which is easy to be cracked, and the security cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mixed...
