Design Of Two-dimentional Code Anti-counterfeiting System Based On Mobile Terminals

As a kind of information carrier, QR Code is encoded by a given encoded format and methedto the loading content messages, that it is expressed and delivered to others in the image form.Andit avoid people identifying the information from it directly in this form,which has excellent securityfor the information carried by QR Code to some extent.But the QR Code that rendered to theelectronic imaging equipments or printed on the solid substrates can be moved and copied easilythough image capturing or printing reproduction.Just for this the QR code without the function ofpreventing itself from replication, and does not to achieve full sense of the anti-counterfeitingfunction.In particular, when the criminals maliciously copy and transfer the QR code that appearedas a tag information carriered in the field of commodity circulation to counterfeit goods, it willdisturb people to discern the forgeries of goods or make genuine manufacturers, sellers andconsumers having great loss.And the barcode anti-counterfeiting technology and means widely usednowadays had flaws, such as dependent on the special equipments, communications network,supported by databases or single anti-counterfeiting revolutions. So it can’t sufficiently meet theneeds of the public that recognizing fake products anywhere and anytime, conveniently andaccurately.In view of the problem that the barcode anti-counterfit technologies at present is lack ofsecurity in commodity trades,a new two-dimensional barcode anti-counterfit identification systemdesign is presented,which is based on the Android operation system that of widely usedsmart-phone and tablet device and combining the two-dimensional barcode technology,digitallyencryption technology and database technology.This new system provides a series of uniqueidentity ID codes for the enterprise products and then adds them with their matching information toa databases.Products’ ID codes will be encrypted by RSA public key encryption algorithm andencoded to two-dimensional barcodes,then the unique identity ID codes and two-dimensionalbarcodes are printed on the products or products’ outer packing and lables.Then the mobile clientsoftware users can use the anti-counterfit identification App with RSA private key to scan theanti-counterfit barcode, and it will automatically recognize and decode the barcode.After that theApp users will read the product’s information and then through comparing it with the product’svendor information the users can identify whether the product is real thing or a counterfeit.Thesystem App has the features that user friendly,high efficiency, low cost,offline operation and soon,and the two-dimensional barcodes generated by this anti-counterfit system are tamper resistant and copy-protection.
