Method and Apparatus for Authorizing RFID Tagged Media

Tag media (DVD, CD, MemoryStick, etc.) with an RFID chip. Use the RIFD information to authorize use of the media when it is in the vicinity of the device where it will be used.

Description of the Invention:

1.      There are a couple of solutions that tag CDs with an RFID and have the drive do the authentication. However, this requires the media to be in the unit that will use it. With hard disk capacity reaching 100s of GB, I would like to have the CD copied to my hard drive and accessed from there.

2.      Instead of doing the authentication in the drive, create a USB attached RFID authenticator.

Media would be inserted in the drive and copied to the device's (PC's) hard disk (or other internal storage). When the program is run from the hard drive, it would request an authentication from the RFID tag in the media using the USB attached RFID reader. There are many protocols that could be used to do this authentication and all have been fairly well documented. Essentially, the RFID tag would respond with a key that would be used together with the media key given by the vendor to authenticate the CD.

The difference is that the original CD would have to be in proximity to the device using the media for it to be validated. You couldn't make a bit-by-bit copy and use the same vendor supplied key on multiple devices.

The media could be in...
