Abstract

A 3D graphical password authentication method displays a 3D grid upon a user'"'"'s request to access a restricted resource. The 3D graphical password authentication method requires the user to enter his or her access password by touching one or more intersections, namely touching the corresponding sensitive areas, on the 3D grid with an input device. A password is then produced as a sequence of the coordinates of the intersections touched along with penup values.

Claims

1. A computer-implemented password authentication method comprising:

a. displaying a three-dimensional (3D) grid with a plurality of horizontal lines in the directions of X-axis and Y-axis and a plurality of vertical lines in the direction of Z-axis on a touch screen of a mobile device upon a user'"'"'s request to access a restricted resource;

b. receiving a password entered by said user using an input device of the mobile device by touching a plurality of sensitive areas surrounding a first intersection inside said 3D grid and a second intersection on an exterior corner of said 3D grid of the horizontal lines and the vertical lines across different planes within said 3D grid, wherein the sensitive areas are visible to said user, and wherein the password is encoded as a sequence of 3D coordinates of said first and second intersections across the different planes within said 3D grid; and

c. granting access to said user if the entered password matches a predetermined password.

2. The method as recited in claim 1, wherein said sensitive area surrounding said first intersection or said second intersection is a 3D space surrounding said first intersection or said second intersection.

3. The method as recited in claim 1, wherein said sensitive area surrounding said first intersection or said second intersection has a predetermined size, shape, pattern, and color.

4. The method as recited in claim 1, wherein said user touches one of said intersections by touching a point of corresponding said sensitive area by using said input device.

5. The method as recited in claim 1, wherein said sensitive area surrounding said first intersection or said second intersection is transparent or hidden.

6. The method as recited in claim 1, wherein said 3D grid includes predetermined number of reference aids, and said reference aids are placed at predetermined positions along said 3D grid.

7. The method as recited in claim 6, wherein said reference aid is comprising of a predetermined number of reference dots having predetermined shape, size, pattern and color, wherein said reference dots are placed at predetermined positions along said 3D grid.

8. The method as recited in claim 6, wherein said reference aid is comprising of a predetermined number of reference cells with predetermined shape, size, pattern and color, wherein said reference cells are placed at predetermined positions along said 3D grid.

9. The method as recited in claim 6, wherein said reference aid is comprising of a predetermined number of reference lines with predetermined shape, size, pattern and color, wherein said reference lines are placed at predetermined positions along said 3D grid.

10. The method as recited in claim 1, wherein each of said first and second intersections of said 3D grid corresponds with a unique value.

11. The method as recited in claim 10, wherein said unique value is a 3D coordinate on said 3D grid.

12. The method as recited in claim 11, wherein said password is a sequence of said 3D coordinates of one or more of said intersection(s) touched on said 3D grid along with pen-up values.

13. The method as recited in claim 1, wherein said 3D grid is zoomed in or out.

14. The method as recited in claim 1, wherein said 3D grid is rotated or flipped.

15. The method as recited in claim 1, wherein an indicator means is used to notify and acknowledge the users input.

16. The method as recited in claim 15, wherein said indicator means is a visual dot indicator appeared simultaneously on touched said first or second intersection as a response to user input, and said visual dot indicator has a predetermined size, shape, pattern and color.

17. The method as recited in claim 15, wherein said indicator means is a visual line indicator appeared simultaneously whenever two said intersections are continuously touched without a break, and said visual line indicator is drawn from a first touched intersection to a second touched intersection on said 3D grid as a response to user input, and said line indicator has a predetermined size, shape, pattern and color.

18. A non-transitory computer-readable medium comprising instructions that are executable by a processor to carry out a password authentication method, the password authentication method comprising:

a. displaying a three-dimensional (3D) grid with a plurality of horizontal lines in the directions of X-axis and Y-axis and a plurality of vertical lines in the direction of Z-axis on a touch screen of a mobile device upon a user'"'"'s request to access a restricted resource; and

b. receiving a password entered by said user using an input device of the mobile device by touching a plurality of sensitive areas surrounding a first intersection inside said 3D grid and a second intersection on an exterior corner of said 3D grid of the horizontal lines and the vertical lines across different planes within said 3D grid, wherein the sensitive areas are visible to said user, and wherein the password is encoded as a sequence of 3D coordinates of said first and second intersections across the different planes within said 3D grid; and

c. granting access to said user if the entered password matches a predetermined password.
