Abstract

A method and apparatus authenticates a user with an image password. In one implementation, a method is provided. According to the method, a plurality of icons are displayed. The plurality of icons are arranged in a pattern. The method receives a sequence of selected inputs. Each of the inputs corresponds to one of the plurality of icons. The method further repositions the plurality of icons after each input and determines whether the user is authenticated based on the received sequence.

Claims

1. A method for authenticating a user, the method comprising:

displaying a plurality of icons, wherein the plurality of icons are arranged in a pattern;

receiving a sequence of selected inputs, wherein each of the inputs corresponds to one of the plurality of icons;

repositioning the plurality of icons after each input; and

determining whether the user is authenticated based on the received sequence.

2. The method of claim 1, wherein each of the plurality of icons is displayed adjacent to a corresponding input device.

3. The method of claim 1, wherein each of the plurality of icons is selectable from a touch screen.

4. The method of claim 1, wherein the pattern is circular in shape.

5. The method of claim 1, wherein during the repositioning of the plurality of icons, the plurality of icons shift at least one position in a clockwise or counterclockwise direction.

6. The method of claim 1, wherein during the repositioning of the plurality of icons, the plurality of icons randomly shift positions.

7. The method of claim 2, wherein selection arrows are positioned between each of the plurality of icons and the corresponding input device.

8. The method of claim 1, wherein when the user is authenticated, the method further comprises unlocking a machine door.

9. The method of claim 1, wherein when the user is authenticated, the method further comprises starting a machine engine.

10. The method of claim 1, wherein program instructions comprising the method are stored in a computer-readable medium.

11. An apparatus for authenticating a user, the apparatus comprising:

a display device, wherein the display device displays a plurality of icons arranged in a pattern;

a processor, the processor executing program instructions for receiving a sequence of selected inputs, wherein each input corresponds to one of the plurality of icons and the plurality of icons are repositioning after receiving each input, the processor further determining whether the user is authenticated based on the received sequence.

12. The apparatus of claim 11, further comprising:

a plurality of input devices, wherein each of the plurality of icons is displayed adjacent to a corresponding of the plurality of input devices.

13. The apparatus of claim 11, wherein each of the plurality of icons is selectable by touching the display device.

14. The apparatus of claim 11, wherein the pattern is circular in shape.

15. The apparatus of claim 11, wherein during the repositioning of the plurality of icons, the plurality of icons shift at least one position in a clockwise or counterclockwise direction.

16. The apparatus of claim 11, wherein during the repositioning of the plurality of icons, the plurality of icons randomly shift positions.

17. The apparatus of claim 12, wherein the processor receives a selection of one of the plurality of icons upon actuation of the corresponding input device.

18. The apparatus of claim 12, wherein selection arrows are positioned between each of the plurality of icons and the corresponding input device.

19. The apparatus of claim 11, wherein when the user is authenticated, the processor causes a machine door to unlock or a machine engine to start.

20. A method for authenticating a user, the method comprising:

receiving an identity of user;

displaying a plurality of icons, wherein the plurality of icons are arranged in a pattern on a touch screen;

receiving a sequence of selected inputs received by the touch screen, wherein each of the inputs corresponds to one of the plurality of icons;

repositioning the plurality of icons after each input; and

determining whether the user is authenticated based on the identify of the user and the received sequence.
