Abstract: A method for theft deterrence of a computer system is disclosed. The computer system includes a trusted platform module (TPM) and storage medium. The method comprises providing a binding key in the TPM; and providing an encrypted symmetric key in the storage medium. The method further includes providing an unbind command to the TPM based upon an authorization to provide a decrypted symmetric key; and providing the decrypted symmetric key to the secure storage device to allow for use of the computer system. Accordingly, by utilizing a secure hard disk drive (HDD) that requires a decrypted key to function in conjunction with a TPM, a computer if stolen is virtually unusable by the thief. In so doing, the risk of theft of the computer is significantly reduced.
