Research And Implementation Of Two-dimensional Code Anti-Counterfeiting System Based On Information Hiding

Along with the rapid increase in the consumption level of the nationals,the consumer market for commodities is also growing.The merchants are paying more and more attention to their own brand benefits in order to ensure the commercial interests,and the demand for commercial anti-counterfeiting is also increasing.Due to the development of Internet technology and the popularity of Internet commerce,the current anticounterfeiting system has been transformed from the traditional material-based anticounterfeiting system to the third-generation anti-counterfeiting system using Internet online authentication.The Internet anti-counterfeiting system has convenient query,high anti-counterfeiting precision and low cost.The advantage,but with the increase in the level of fraud,the third generation of anti-counterfeiting systems now have the possibility of being copied.As an important online and offline information transmission medium in the Internet,the two-dimensional code has its characteristics of rapid identification and low cost.It has also emerged in the field of Internet anti-counterfeiting,but the anticounterfeiting performance of QR code still exists.Big problem.In order to improve the anti-counterfeiting performance of QR code in commercial anti-counterfeiting,this paper uses the combination of two-dimensional code and information hiding technology to design the anti-counterfeiting system.The main work contents are as follows:(1)By analyzing the existing information of the two-dimensional code information hiding performance: the smaller the image information,the lower the robustness and the lower the color of the image information,the lower the transparency,which appears in the two-dimensional code.Two problems have been proposed to add a new generation technology of background image color QR code,which improves the information hiding performance of the QR code.(2)By analyzing the existing digital watermark embedding technology,a new digital watermark embedding algorithm is improved and researched.The algorithm has the semifragile watermarking property that is robust to one-time printing and robust to secondary copying.This semi-fragile watermark can realize whether the two-dimensional code is copied by copying.(3)According to the system requirements,the two-dimensional code anticounterfeiting system based on information hiding is designed and implemented.The client APP is developed by mobile Android,the server is developed based on Django server,and the database is MySQL database.After the system is implemented,the function tests of each unit function module are performed,and the overall performance of the system is tested to verify the performance of the system in the case of multiple concurrent situations.
