Character two-dimension code encoding and decoding method for short message

Abstract

The invention relates to a character two-dimension code encoding and decoding method for a short message, which is used for solving the problems that the storage space occupation of a two-dimension code based on an image is large and the transmission efficiency is low, and has the advantages of capability of storing bar codes by characters, efficient transmission, and simple and efficient encoding and decoding algorithms. A character two-dimension code is a rectangular-shaped character two-dimension matrix module and the matrix module is composed of view finding sign units, a version number unit, a data specification number unit and a data region sign unit, wherein three view finding sign units are arranged and respectively located at the upper left corner, a upper right corner and the lower right corner of the matrix module; the version number unit is located in back of the view finding sign unit which is located at the upper left corner of the matrix module; the data specification number unit is located in back of the version number unit; and the data region sign unit is located in back of the data specification number unit. According to the character two-dimension code encoding and decoding method for the short message, character two-dimension bar codes are widely applied to electronic commerce.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional barcodes, in particular to a short message-oriented character two-dimensional code encoding method and decoding method. Background technique [0002] The development of two-dimensional bar codes has been used in many applications, especially the combination with mobile terminals and wireless networks makes two-dimensional codes have the characteristics of the information age, brings a variety of applications to life, and can conveniently realize mobile electronic ticketing. As a new, efficient, environmentally friendly and safe paperless electronic voucher, mobile electronic tickets have aroused widespread interest from merchants and operators. This new type of bill has already begun to be used, and the content of the traditional paper bill and the holder's information are compiled into a two-dimensional code graphic, which is sent to the user's mobile phone through the mobile wireless net...
