Abstract
A data storage device comprising: a storage medium; a communication interface to enable communication with a host device; and a flash translation layer (FTL) module. The FTL module is configured to: receive a fingerprint key of an enrolled user from a fingerprint sensor; determine selective access restrictions of the enrolled user based on the fingerprint key; and in response, enable the host device selective access to user data in the storage medium in accordance with the selective access restrictions. Selective access is enabled by receiving a corresponding portion of a logical to physical (L2P) table associated with the selective access restrictions of the enrolled user.
