Abstract
A device for secure data storage has a host unit that obtains data stored on an external device at an external storage address; a user signal generator that generates a user defined security signal based on the external storage address of the data that indicates a security level of the data; a storage address determining unit that determines an internal storage address for the data based on the security level of the data; and a storage unit that stores the data at the internal storage address corresponding to the security level.
Claims22
A device for secure data storage, comprising:
- a host unit configured to obtain data stored on an external device at an external storage address;
- a user signal generator configured to generate a user defined security signal based on said external storage address of said data that indicates a security level of said data;
- a storage address determining unit configured to determine an internal storage address for said data based on said security level of said data;
- and
- a storage unit configured to store said data at said internal storage address corresponding to said security level.
A method for secure data storage, comprising:
