ZHANG Bin;WANG Yue;Jinan Bureau of Quality and Technical Supervision;National Network Software Testing Center(Jinan);  
With the great concern of information security from state level,the security of two- dimensional code becomes the focus of society. Based on QR code,the most widely- used one in matrix two- dimensional codes,the graphics structure,encoding mode and encoding process of QR code are expounded,several common methods attacking two- dimensional code summarized,and protection strategies in coordinate introduction of security mechanism from both encoding and parsing links also presented. The purpose is to regulate the operation order of two- dimensional code from technical level and the top- level architecture of two- dimensional code industry,thus promoting the two- dimensional code industry and forming the unified encoding system,analytical system,application standard and industry standard.
