More Information
Summary:The invention provides a coding system. The system comprises a coded data acquisition module and a data coding module, wherein the coded data acquisition module is used to acquire data information; the data coding module is used to code the data information and generate plain code data; secret data is added into the plain code data; and the plain code data and the secret data are coded so as to generate a two-dimension code symbol. The invention also provides a decoding system. The decoding system comprises a decoding data acquisition module, a data analysis module and a data decoding module, wherein the decoding data acquisition module is used to acquire data information; the data analysis module analyzes the two-dimension code symbol and acquires coding mode information; the data decoding module decodes the two-dimension code symbol and acquires data information. The coding system and the decoding system of the invention have the following advantages that safety of opening two-dimension code is increased; and problems that data secrecy can not be performed in an existing international two-dimension code standard; supports of a private two-dimension code are not enough and flexibility is poor are solved.
