RFID ASSISTED MEDIA PROTECTION, TRACKING AND LIFE CYCLE MANAGEMENT

摘要

A data storage apparatus (132), e.g., optical disc, flash memory or hard disk is provided with an RFID tag (136) for controlling its use. The RFID tag stores biometric authentication data (235-255) of a user, in addition to information (210) for decrypting encrypted data on the data storage apparatus. A digital representation (305-320) of a biometric input of the user is obtained, and a message digest function is used to obtain the biometric authentication data. Subsequently, biometric authentication data from a new biometric input is compared to the stored data. If the data matches, the decryption information (210) is read from the RFID tag, and use to decrypt the encrypted data. Only a portion of the data on the data storage apparatus, such as headers (1102) of frames (1100), need be encrypted. The RFID tag may also store purchase validity data (212) added at a point of sale.
