Solid state memory and method for protecting digital contents by interrupting copying or accessing and proceeding only upon user verification or authentication

Abstract

A solid state memory including a processor and a method for protecting the digital contents of the solid state memory. The microprocessor inserts at least an interruption during a copying or a reading of the digital contents and proceeds with the copying or reading only subsequent to a verification of a PIN or other user action. In particular, the verification provides control to ensure that the PIN is inserted manually. Access may be prevented if a time elapsed between the interruption and inputting of a PIN is shorter than a threshold time representing a speed of manual input, or if the PIN does not correspond to a sequence of requests for access to selectable files, which may be virtual files. The interruption may comprise substituting altered or cryptographic data if verification fails, or reproduction of an audio or visual message to be understood by the user.
