APPARATUS AND STORAGE MEDIUM FOR DECRYPTING INFORMATION

摘要

A system including a storage medium containing encrypted information comprises: (a) a control unit for selecting information to be retrieved from the storage medium; (b) a storage medium reader for reading the selected information from the storage medium; and (c) a decryption device for decrypting at least portions of the selected information using a decryption key. The decryption key is defined, at least in part, by rules and/or data which are read from the storage medium by the storage medium reader. A different and unique key is associated with each separate item or file of encrypted information.
