Abstract
Data stored in a portable storage device are encrypted, for example by a processor of the portable storage device itself, using a backup key and stored in a backup medium. The backup key is protected by being stored in a backup key storage medium, such as an internet server, a pocketable medium or a trusted computer, preferably after being encrypted using a password. As needed, the backup key is retrieved and used to decrypt the data from the backup medium. The decrypted data are restored to the original portable storage device or to a different portable storage device.
