Abstract
The present invention provides a software copyright protection and licensing system (200) using RFID. A RFID tag (110) is supplied with a software package (100). During installation of the software package in a computer, a RFID reader (158) interrogates the RFID tag (110) for a product installation and licensing key (114). During installation of the software, an installation signature (TSig) is generated and stored in the RFID tag and computer, operation of the software is allowed if the installation signatures tally, otherwise permission is denied. Further, the system (200) allows reinstallation (process C) of the software and/or re-generation (process D) of a new installation signature under certain situations.
