無源射頻標籤反假冒的系統和方法
An anti-counterfeit system and method for passive radio frequency label are disclosed, the system includes: the anti-counterfeit module of label, by the user interface, the production owner adopts the general international coding scheme to convert the true EPC code into the fake EPC code and the fake EPC code is mounted on the label, and generates the cipher key value by Hasi function, the readersends the lock command to lock the fake EPC according to the cipher value; when checking, the reader reads the fake EPC code on the label and display the fake EPC code on the rear processing unit; and then the reader sends the unlock command, the label is processed by the anti-counterfeit detection according to the generated key value, if the label is true, the fake EPC code can be converted intothe true EPC code by the user's coding scheme, and enters the rear processing unit to process the information retrieval according to the true EPC code; the built-in security access mechanism improvesthe difficulty to copy the great labels and improves the security of label information greatly.
