A system (10) is provided for authenticating and securing product transactions An integrated circuit is attached to a target (22), such as an optical disc or electronic device The integrated circuit has an RF transceiver (2) that is capable of establishing communication with an associated reading device The integrated circuit also has a hidden memory (16), which can not be read externally, and a user memory The hidden memory (16) stores an authentication message, while the user memory stores readable authentication information The hidden authentication message and the authentication information are related through a cryptographic process However, even though the integrated circuit benefits from the cryptographic security, the integrated circuit only operates relatively simple logic operations In this way, a highly secure transaction is enabled without requiring significant processing power or time at the integrated circuit |
