ABSTRACT:
A method for verifying authenticity of an object includes the steps of: enabling an electronic device to generate and transmit a request signal; in response to the request signal, enabling an RFID tag to generate a first authentication code based on a varying secret key, a second authentication code based on a unique identification code of the RFID tag and the varying secret key, and a third authentication code that is based on the unique identification code of the RFID tag and the first and second authentication codes, and to wirelessly transmit the third authentication code for reception by the electronic device; and enabling the electronic device to forward the third authentication code received from the RFID tag to an authenticating center for verification. A system, which includes the RFID tag, the electronic device, and the authenticating center, and which performs the method is also disclosed.
