Abstract

The invention discloses a microscopic code encryption method and system. Comprising the steps of obtaining input to-be-encrypted data; encrypting the to-be-encrypted data according to the encryption rule to obtain a decimal digital character string; values are taken in sequence according to the numeric character strings and the value taking rule of fixed digits, the obtained values serve as included angle information and distance information in sequence and are grouped, and each group comprises one piece of included angle information and one piece of distance information; and placing a preset first identifier at the central position of the blank image. According to the technical scheme, the first identifier is generated to serve as the graph center, the data are converted into the distance and the angle of the second identifier, and due to the fact that information contained in the distance and the angle is far larger than information expressed by logic 0 or 1, more data can be encrypted through one second identifier, and the encryption efficiency is improved. And meanwhile, a gap exists between the first identifier and the second identifier, so that subsequent data decryption is not influenced even if no damage exists, and the anti-fouling capability is improved.

Description

technical field [0001] The invention relates to the technical field of graphic data codes, in particular to a microscopic code encryption method and system. Background technique [0002] Two-dimensional code is also called two-dimensional barcode. The common two-dimensional code is QR Code. The full name of QR is Quick Response. It is a very popular coding method on mobile devices in recent years. It can store more The information can also represent more data types. [0003] Two-dimensional bar code (2-dimensional bar code) is a graphic that uses a specific geometric figure to be distributed on a plane (two-dimensional direction) according to a certain rule, black and white, and records data symbol information; it is cleverly used in code compilation The concepts of "0" and "1" bit streams that constitute the internal logic basis of the computer use several geometric shapes corresponding to the binary to represent text and numerical information, and automatically read throu...
