Abstract

Embodiments described are generally directed to ensuring a data storage device originated from a first location. The data storage device including a unique identifier visibly attached to said data storage device and the unique identifier digitally retained by the data storage device. At a first location a first hash of said unique identifier is generated via a hash function. Also at the first location a public key and a private key are created. The first hash is cryptographically signed using the private key. Before sending the data storage device to a second location the cryptographically signed hash is stored to the data storage device along with the public key. At the second location, a second hash of said unique identifier is generated using the same hash function used at the first location. The second hash is compared with a recovered version of the cryptographically signed hash which is decrypted by pairing the cryptographically signed hash with said public key. If the second hash is the same as the recovered first hash the data storage device is validated as originating from the first location.
