Abstract

Encryption of a key using another key that is unique and particular to a given client is disclosed. In one embodiment, a computer-implemented method determines a first key that is unique and particular to the client, without user intervention. In varying embodiments, this key can be one or more of: a processor identifier, a network card address, an IP address, a checksum of a component, a serial number of a hard disk drive, a number of cylinders of a hard disk drive, and a user name in a registry file. At least a second key that provides access to information, such as multimedia information, is encrypted with this first key. The second key as encrypted with the first key may be stored on a storage.
