| With the rapid development of social economy,the use of bills has become more frequent.But the security of the bill has always been a hot spot of attention.The human biological characteristics are unique and concealed,which are the hot spots in the research and application of anti-counterfeiting technology at present.The use of human biometric technology in practical bills will be an effective way to enhance the security of bills.The traditional bill mainly relies on ink,graphics,paper and other ways to prevent the bill itself,but neglects the authentication of the identity of the bill user.In order to enhance the security of negotiable instruments,In this paper,the algorithm of generating QR code by body biology character is studied,and the QR code is drawn into the bill through a virtual bridging printer.First,the characteristics of QR code are studied,and the principle and process of coding and decoding of QR code are studied.Secondly,in order to store the body biology characterin QR code,the coding algorithm of QR in Zxing is improved,and the QR coding of body biology character is realized.Thirdly,in order to realize the printing of certification bills,this paper proposes a system implementation plan based on virtual bridging printing.By printing data interception and authentication information superposition,we achieve the output of certified bill with QR code body biology characterdata carrier.Finally,this paper improves the QR decoding algorithm in Zxing,and develops the mobile authentication application on the Android platform,which is used to restore the body biology characterin the ticket,and provide a basis for verifying the true identity of the bill users.This paper proposes a method for verification of bill users.The system design is complete and feasible.Experiments show that we can achieve the goal of validates the identity of the users. |
