Abstract
Various embodiments of the present disclosure are directed to a storage device having a non-volatile memory, a Proof of Physical Access (PPA) mechanism and a controller circuit. The PPA mechanism generates a PPA value responsive to a direct physical user interaction with the storage device by a user. In response to receipt of a storage command from a host, the controller circuit executes the received storage command responsive to the storage command being determined to be a protected command and responsive to detection of the PPA value during a predetermined window of time. The controller circuit does not execute the received storage command responsive to the storage command being determined to be a protected command and responsive to an absence of the PPA value during the predetermined window of time. The protected command is a command that changes access to data stored in the non-volatile memory.
