Abstract

A portable non-volatile memory device and method for preventing unauthorized access to data stored on the memory device is provided. The invented memory device and method prevents unauthorized access to data stored on the device without requiring self-installing software to protect the data stored on the device. Data and information stored on the device may be accessed or manipulated quickly. Coupling the invented device to the computer activates the device. Upon activation, a window is generated on a computer screen. A Graphical User Interface requests authentication information for accessing data stored on the device. If the correct authentication information is input, then access to the data stored on the invented device is granted, otherwise access to the data is denied. Once access is granted, data stored on the device may be displayed in the window and can be transferred between the device and a host computer.

Claims

1. A method for preventing unauthorized access to data stored on a memory device, the method comprising the following steps:

(a) coupling the memory device to a host device;

(b) generating a graphical user interface;

(c) requesting authentication information;

(d) inputting authentication information;

(e) determining if the authentication information is correct; and

(f) if the authentication information is correct, then granting access to data stored on the memory device, and if the authentication information is not correct then denying access to the data on the memory device.

2. The method of claim 1 wherein the authentication information comprises one of a username, a password, and a personal identification number.

3. The method of claim 1 wherein the memory device comprises a portable memory device.

4. The method of claim 3 wherein the portable memory device contains solid-state memory for storing data.

5. The method of claim 1 wherein the host device comprises a computer that includes a display.

6. A method for preventing unauthorized access to data stored on a portable memory device without requiring self-installing software to protect the data stored on the device, the method comprising the following steps:

(a) coupling the portable memory device to a host device to activate the memory device;

(b) displaying information on the host device

(c) generating a graphical user interface requesting authentication information from the host device;

(d) inputting authentication information;

(e) determining if the authentication information is correct; and

(f) if the authentication information is correct, then granting access to data stored on the memory device and displaying the data on the host device, and if the authentication information is not correct then denying access to the data on the memory device,

whereby unauthorized access to data stored on the memory device is prevented without uploading self-installing software to the host device.

7. The method of claim 6 wherein the authentication information comprises at least one of a username, a password, and a personal identification number.

8. The method of claim 6 wherein the portable memory device contains solid-state memory for storing data.

9. The method of claim 6 wherein the host device comprises a computer that includes a display device.

10. The method of claim 9 further comprising:

generating a window on the display device of the computer.

11. The method of claim 9 wherein the graphical user interface is displayed on the display device of the computer.

12. The method of claim 10 wherein the information displayed on the display device of the computer includes systems files stored on the portable memory device and displayed in the window generated on the display device of the computer.

13. The method of claim 10 wherein upon granting access to data stored on the memory device the data is displayed in the window generated on the display device of the computer.

14. A portable memory device configured to prevent unauthorized access to data stored thereon comprising:

a housing containing a processor for processing data and a memory for storing data; and

an interface for coupling the memory device to a host device, the processor coupled to the interface for sensing if the memory device is coupled to a host device, if the memory device is coupled to a host device, then the processor runs a program that displays information on the host device, the program generating a graphical user interface requesting authentication information from the host device, if the authentication information from the host device matches authentication information stored in memory, then access to data stored in memory is granted, and if the authentication information from the host device does not match authentication information stored in memory, then access to data stored in memory is denied.

15. The device of claim 14 wherein the authentication information comprises at least one of a username, a password, and a personal identification number.

16. The device of claim 14 wherein the portable memory device contains solid-state memory for storing data.

17. The device of claim 14 wherein the host device comprises a computer that includes a display device, the graphical user interface is displayed on the display device of the computer.

18. The method of claim 17 wherein upon granting access to data stored on the memory device the data is displayed in a window generated on the display device of the computer.
