Design And Research Of Avoid Instead Signing System Based On 2-Dimensional Code

"Fast,convenient and efficient" are the three purposes constantly pursued in the age of big data in information-based society.Signing-in,used as one of the regular,common and frequent work content,can be seen everywhere in commuting,meeting and other occasions.With the popularity of smart phones,the application scenes of QR codes in mobile terminals are increasingly rich.In order to improve the work efficiency of signing by developing a signing system feathering common use,convenience,utility and simplicity,it is of great feasibility to introduce QR code technology in to achieve "the three major purposes ".The paper uses the QR code technology to realize the signing-in information encryption,decryption and verification.On signing-in system two important problems that must be solved has been put forward.In order to solve the problem of the unique identification number for the person concerned and avoiding issuing,the four solutions put forward have undergone a comprehensive balance by taking a number of factors into consideration,namely the system complexity,issuing evade,economy,efficiency and stability,and deployment flexibility and convenience,and the applicability.Consequently based on the practical application scene,the final design scheme has evaluated and accordingly chosen QR code signing-in business type from such eight aspects as signing-in type,signing-in speed and efficiency,current user habit,server security and load,increase validation to avoid issuing,richness and flexibility of the QR code information carrier QR code,finally actualized the QR code issuing avoidance system.
