Abstract

A wireless authentication system for universal serial bus (USB) storage device has a USB storage device mounted on a computer unit with the storage device wirelessly connected to a remote device. The remote device has a dedicated application installed therein and transmitting authentication information to the storage device for establishing a dedicated link. A storage space of the storage device is set by the computer unit to be accessible. When users activate the remote device for sending out an operation command, the operation command includes at least one encryption command and at least one decryption command. The storage device performs a corresponding data management mode according to the operation command. Accordingly, the storage device can be wirelessly managed to enhance personal data security and operational convenience of the storage device.

Claims

1. A wireless authentication system for universal serial bus (USB) storage device, comprising:

a computer unit;

a USB storage device mounted on the computer unit and having;

a first communication module;

a power module;

an access module; and

a controller electrically connected to the first communication module, the power module and the access module, the controller receiving a piece of authentication information through the first communication module, and determining if the access module is allowed for data access according to the piece of authentication information; and

a remote device having a second communication module, wirelessly connecting to the first communication module of the USB storage device through the second communication module, and transmitting the piece of authentication information to the USB storage device.

2. The wireless authentication system as claimed in claim 1, wherein the access module has a first storage unit, when the first communication module successfully establishes a wireless link with the second communication module, the controller changes the first storage unit from a hidden state to an overt state for the computer unit to treat the first storage unit as an open and accessible disk region, and when the first communication module is not connected to the second communication module, the controller changes the first storage unit from the overt state to the hidden state for the computer unit to treat the first storage unit as a hidden and inaccessible disk region.

3. The wireless authentication system as claimed in claim 1, wherein a dedicated application installed in a processor of the remote device establishes the wireless link between the first communication module and the second communication module.

4. A wireless authentication method for universal serial bus (USB) storage device performed by a USB storage device when the USB storage device is wirelessly connected to a remote device, the wireless authentication method comprising steps of:

accepting a piece of authentication information from the USB storage device to establish a dedicated wireless link between the USB storage device and the remote device having a dedicated application installed therein; and

changing a storage space of the USB storage device from a hidden state to an overt state for data access according to a successful and dedicated wireless link established between the USB storage device and the remote device.

5. The wireless authentication method as claimed in claim 4, further comprising steps of:

receiving an operation command generated from the dedicated application installed in the remote device; and

performing a corresponding data management mode according to the operation command to set the storage device to be in the hidden state or in the overt state.

6. The wireless authentication method as claimed in claim 5, wherein when the operation command is a fully-locking command, the step of performing the corresponding data management mode has steps of:

accepting the fully-locking command; and

setting the storage device to be inaccessible or hidden according to the fully-locking command.

7. The wireless authentication method as claimed in claim 5, wherein when the operation command is a partially-locking command, the step of performing the corresponding data management mode has steps of:

accepting the partially-locking command; and

setting the storage device to be partially locked and inaccessible or partially hidden according to the partially-locking command.

8. The wireless authentication method as claimed in claim 6, wherein when the operation command is a fully-unlocking command, the step of performing the corresponding data management mode has steps of:

accepting the fully-unlocking command; and

setting the storage device to be accessible or reappearing according to the fully-unlocking command.

9. The wireless authentication method as claimed in claim 7, wherein when the operation command is a partially-unlocking command, the step of performing the corresponding data management mode has steps of:

accepting the partially-unlocking command to unlock a partially-locked storage space of the storage device; and

setting the partially-unlocked storage space of the storage device to be reappearing or accessible.

10. The wireless authentication method as claimed in claim 4, wherein the piece of authentication information includes a piece of management level information, and the operation command received by the remote device has more than one privilege.

11. The wireless authentication method as claimed in claim 5, wherein the piece of authentication information includes a piece of management level information, and the operation command received by the remote device has more than one privilege.

12. The wireless authentication method as claimed in claim 6, wherein the piece of authentication information includes a piece of management level information, and the operation command received by the remote device has more than one privilege.

13. The wireless authentication method as claimed in claim 7, wherein the piece of authentication information includes a piece of management level information, and the operation command received by the remote device has more than one privilege.

14. The wireless authentication method as claimed in claim 8, wherein the piece of authentication information includes a piece of management level information, and the operation command received by the remote device has more than one privilege.

15. The wireless authentication method as claimed in claim 9, wherein the piece of authentication information includes a piece of management level information, and the operation command received by the remote device has more than one privilege.
