Applications for removable storage

A method for selective security of data transfer from a transfer device to a removable storage medium, comprising:

• for data transfer to said removable storage medium:
• correlating data to an identifier associated with said transfer device and said removable storage medium with a content code;
• encrypting said data, wherein said transfer device encrypts said data and writes said encrypted data to said removable storage medium;
• and
• generating a passkey for inclusion with said encrypted data, wherein said passkey includes said content code, said transfer device identifier and said removable storage medium identifier;
• and
• for data access from said removable storage medium:
• requesting an encryption code from said server for decrypting said encrypted data, wherein said request includes said passkey;
• verifying that said encrypted data which was written by said transfer device to said removable storage medium, wherein said data, transfer device and removable storage medium are identified respectively by said content code, transfer device identifier and removable storage medium identifier of said passkey;
• and
• issuing said encryption code for decrypting of said encrypted data upon said verification.

An apparatus for selectively securing data to a removable storage medium, comprising:

• a drive circuit adapted to read and write to said removable storage medium;
• a processor coupled to said drive circuit and adapted to determine an identifier associated with said removable storage medium, said processor further having an input for coupling to a server for verifying said removable storage medium identifier;
• and
• a memory coupled to said processor and adapted to store said data, wherein said processor is further adapted to encrypt said stored data and instruct said drive circuit to write said encrypted data to said removable storage medium;
• and wherein
• said processor is further adapted to generate a passkey comprising said removable storage medium identifier, a content code associated with said data, and an identifier associated with said processor, wherein said processor further instructs said drive circuit to write said passkey to said removable storage medium.
