Electronic paper based dynamic two-dimensional code cipherer and implementation method therefor

Abstract

The present invention relates to the field of wireless communication technologies, in particular to an electronic paper based dynamic two-dimensional code cipherer and an implementation method therefor. The electronic paper based dynamic two-dimensional code cipherer mainly comprises a dot matrix electronic paper screen module, a two-dimensional code security module, a crystal oscillation circuit module, a micro processing unit module and a battery module; and an output end of the micro processing unit module is connected to the dot matrix electronic paper screen module, an input end of the micro processing unit module is connected to the crystal oscillation circuit module, the battery module and the two-dimensional code security module, and an input end of the two-dimensional code security module is further connected to output ends where the crystal oscillation circuit module and the battery module are arranged. After adopting the structure, the electronic paper based dynamic two-dimensional code cipherer uses ultra low power consumption of dot matrix electronic paper as a carrier, so that power consumption of the dynamic cipherer is reduced and a service life of the cipherer is prolonged; and information reading can be facilitated by using a two-dimensional code format, and meanwhile, security of information is also improved.

Description

technical field [0001] The invention relates to the field of wireless communication technology, in particular to an electronic paper-based dynamic two-dimensional code cipher and its implementation method. technical background [0002] A two-dimensional code is a black and white pattern that uses a specific geometric pattern to record data symbol information on a plane according to a certain rule; in the code compilation, the "0" and "1" bit streams that constitute the internal logic basis of the computer are cleverly used The concept of using a number of geometric shapes corresponding to binary to represent text and numerical information, automatic reading through image input equipment or photoelectric scanning equipment to realize automatic processing of information: it has some common features of barcode technology: each code system has Its specific character set; each character occupies a certain width; it has certain verification functions, etc. At the same time, it al...

Problems solved by technology

The passwords generated by this kind of dynamic two-dimensional code cipher are generally numbers or letters, with fewer digits, and are displayed in plain text, so the security is poor; some require a special device to read when reading, and manual input Verification codes and other operations are cumbersome; and some of the generated two-dimensional codes have viruses inside, which brings a lot of trouble to users, so the dynamic two-dimensional code cipher with this structure cannot meet people's needs
