Abstract
A detachable storage device can comprise a memory, circuitry, and a user interface. The memory may comprise a storage partition. The circuitry may be configured to authorize access to the storage partition to a digital device when the detachable storage device is coupled to the digital device based, at least in part, on a user code. The user interface may be configured to receive the user code while the detachable storage device is within a detached state and provide the user code to the circuitry to allow access to the storage partition.
Claims24
A storage device comprising:
- memory comprising at least first and second storage partitions, the first storage partition including encrypted data that is decrypted after a first user code is received;
- circuitry configured to authorize access to the first storage partition when the first user code is received;
- and
- a user interface configured to receive the first user code while the storage device is in a detached state, the user interface further configured to provide the first user code to the circuitry;
- wherein the circuitry is programmed to:
- deny access to the second storage partition when the first user code is received;
- allow access to the second storage partition and not to the first storage partition when a second user code is received;
- allow access to the first and the second storage partitions when a third user code is received;
- and
- reset the first, second, and third user codes when a reset code is received by the circuitry.
A method comprising:
- receiving a first user code to allow access to a storage device having at least first and second storage partitions , wherein the storage device is in a detached state when receiving the first user code;
- authorizing access to the first storage partition when the storage device is coupled to a digital device, based at least in part on the first user code;
- denying access to the second storage partition when the storage device is coupled to the digital device, based at least in part on the first user code;
- allowing access to the first and second storage partitions based on the storage device receiving a second user code;
- resetting the first and second user codes based on receiving a reset code by the storage device;
- and
- erasing data in the first and second storage partitions when the reset code is received by the storage device.
A non-transitory computer readable medium having embodied thereon a program, the program executable by a processor for performing a method comprising:
- receiving a first user code with a portable memory device in a detached state, the portable memory device having at least first and second storage partitions;
- descrambling a database file system associated with the first and second storage partitions, utilizing the first user code;
- authorizing access to the first partition and denying access to the second partition, based on the first user code;
- receiving a second user code with the portable memory device in the detached state;
- authorizing access to the second partition and denying access to the first partition, based on the second user code.
