Abstract

A graphical password authentication arrangement and method display a grid on a display upon a user'"'"'s request to access a restricted resource. The graphical password authentication arrangement requires the user to enter his or her access password by selecting one or more intersections on the grid on the display with an input device. A processing means determines whether to grant the user to access the restricted resource by comparing the access password entered with a corresponding file password for the user, which is stored in a storage means.

Claims

1. A graphical password authentication arrangement comprising:

a. a display for displaying a grid with a plurality of horizontal and vertical lines on said display upon a user'"'"'s request for accessing a restricted resource; and

b. an input device for entering a password by said user by selecting one or more intersections on said grid on said display.

2. The arrangement as recited in claim 1, wherein said horizontal and vertical lines are curved or distorted.

3. The arrangement as recited in claims 1, wherein said display includes predetermined number of reference aids, wherein said reference aids are placed at predetermined positions along said grid on said display.

4. The arrangement as recited in claim 3, wherein said reference aid is comprising of a predetermined number of reference dots having predetermined shape, size, and color, wherein said reference dots are placed at predetermined positions along said grid on said display.

5. The arrangement as recited in claim 3, wherein said reference aid is comprising of a predetermined number of reference cells with predetermined color and pattern, wherein said reference cells are placed at predetermined positions along said grid on said display.

6. The arrangement as recited in claim 1, wherein said intersection has a corresponding locating scope around it, whereby said user selects one of said intersections by touching inside an area of said corresponding locating scope with using said input device, wherein said touching includes tapping inside said area of said locating scope and passing through said area of said locating scope with said input device.

7. The arrangement as recited in claim 6, wherein said locating scope of said intersection has a predetermined size and shape.

8. The arrangement as recited in claim 1, wherein an indicator means is provided to notify and acknowledge the user'"'"'s input.

9. The arrangement as recited in claim 8, wherein said indicator means is a visual dot indicator appeared simultaneously on selected intersection of said grid as a response to user input, and said visual dot indicator has a predetermined size, shape and color.

10. The arrangement as recited in claim 8, wherein said indicator means is more than one dot indicators appearing simultaneously on intersections including selected intersection of said grid on said display to disguise a true input entered by a user, and said visual dot indicator has a predetermined size, shape and color.

11. The arrangement recited in claim 8, wherein said indicator means is a visual line indicator appeared simultaneously whenever two intersections are continuously selected without a break, and said visual line indicator is drawn from the first selected intersection to the second selected intersection on said grid as a response to user input, and said line indicator has a predetermined style, size, shape and color.

12. The arrangement as recited in claim 8, wherein said indicator means is more than one visual line indicators appearing simultaneously on said grid on said display to disguise a true input entered by a user, and said visual line indicator has a predetermined style, size, shape and color.

13. A graphical password authentication method comprising:

a. displaying a grid with a plurality of horizontal and vertical lines on a display upon a user'"'"'s request to access a restricted resource; and

b. entering a password by said user using an input device by selecting one or more intersections on said grid.

14. The method as recited in claim 13, wherein said display includes predetermined number of reference aids, and said reference aids are placed at predetermined positions along said grid on said display.

15. The method as recited in claim 14, wherein said reference aid is comprising of a predetermined number of reference dots having predetermined shape, size and color, wherein said reference dots are placed at predetermined positions along said grid on said display.

16. The method as recited in claim 14, wherein said reference aid is comprising of a predetermined number of reference cells with predetermined color and pattern, wherein said reference cells are placed at predetermined positions along said grid on said display.

17. The method as recited in claim 13, wherein an indicator means is used to notify and acknowledge the users input.

18. The method as recited in claim 17, wherein said indicator means is a visual dot indicator appeared simultaneously on selected intersection of said grid as a response to user input, and said visual dot indicator has a predetermined size, shape and color.

19. The method recited in claim 17, wherein said indicator means is a visual line indicator appeared simultaneously whenever two intersections are continuously selected without a break, and said visual line indicator is drawn from the first selected intersection to the second selected intersection on said grid as a response to user input, and said line indicator has a predetermined style, size, shape and color.

20. An article of manufacture comprising:

a. computer-readable program code module for handling user input from an input device;

b. computer-readable program code module for manipulating a display displaying a grid with a plurality of horizontal and vertical lines and requiring the user to enter password by selecting one or more intersections on said grid on said display;

c. computer-readable program code module for manipulating a storage means to register and to store file passwords; and

d. computer-readable program code module for manipulating a processing means for determining user access to a restricted resource by comparing an entered access password with said file password corresponding to said user, wherein said file password is stored in said storage means.
