Systems and methods for increased security in authentication code entry for touch-sensitive screen enabled devices

1. A method for enhanced security in entering data to a data entry device comprising at least one computer processor and a touch-sensitive screen, comprising:

the at least one computer processor generating a touch instruction to add fingerprint marks or touch marks to the touch-sensitive screen;

the touch-sensitive screen displaying the touch instruction, the touch instruction indicating a touch location where a user touch is to be made on the touch-sensitive screen to add the fingerprint marks or touch marks;

the touch-sensitive screen sensing a first touch; and

the at least one computer processor determining that the first touch is within a predetermined threshold of the touch location indicated by the touch instruction.

2. The method of claim 1 , wherein the touch instruction instructs the user to traverse a portion of the touch-sensitive screen with the user touch; and the method further comprises the at least one computer processor determining that the first touch traverses the portion of the touch-sensitive screen indicated by the touch instruction within a predetermined threshold of the touch instruction.

3. The method of claim 2 , further comprising:

the at least one computer processor determining that the sensed touch is continuous.

4. The method of claim 1 , wherein the touch instruction is generated to add to or obfuscate existing fingerprints or touch marks on the touch-sensitive screen from at least one previous touch sensed by the touch-sensitive screen based on the location of the at least one previous touch sensed by the touch-sensitive screen.

5. The method of claim 1 , wherein the touch-sensitive screen displays a virtual keypad comprising a plurality of virtual keys, and the touch instruction is based on a number of virtual keys that will be traversed by the touch instruction.

6. The method of claim 1 , wherein the touch instruction is a symbol displayed on the touch-sensitive screen.

7. The method of claim 1 , further comprising:

the at least one computer processor generating a second touch instruction to add second fingerprint marks or touch marks to the touch-sensitive screen based on the location of the first touch; and

the touch-sensitive screen displaying the second touch instruction indicating a second touch location where a user is to touch the touch-sensitive screen to add the second fingerprint marks or touch marks.

8. The method of claim 1 , further comprising:

the touch-sensitive screen receiving an authentication code.

9. The method of claim 1 , wherein the data entry device comprises a point of sale device.

10. A data entry device comprising:

a touch-sensitive screen;

a memory; and

at least one computer processor;

wherein:

the at least one computer processor generates a touch instruction to add fingerprint marks or touch marks to the touch-sensitive screen;

the touch-sensitive screen displays the touch instruction, the touch instruction indicating a touch location where a user touch is to be made on the touch-sensitive screen to add the fingerprint marks or touch marks;

the touch-sensitive screen senses a first touch; and

the at least one computer processor determines that the first touch is within a predetermined threshold of the touch location indicated by the touch instruction.

11. The data entry device of claim 10 , wherein the touch instruction instructs the user to traverse a portion of the touch-sensitive screen with the user touch, and the at least one computer processor determines that the first touch traverses the portion of the touch-sensitive screen indicated by the instruction within a predetermined threshold of the touch instruction.

12. The data entry device of claim 11 , wherein the at least one computer processor determines that the sensed touch is continuous.

13. The data entry device of claim 10 , wherein the at least one computer processor generates the touch instruction to add to or obfuscate existing fingerprints or touch marks on the touch-sensitive screen from at least one previous touch sensed by the touch-sensitive screen based on the location of the at least one previous touch sensed by the touch-sensitive screen.

14. The data entry device of claim 10 , wherein the touch-sensitive screen displays a virtual keypad comprising a plurality of virtual keys, and the touch instruction is based on a number of virtual keys touched by the touch instruction.

15. The data entry device of claim 10 , wherein the touch instruction is a symbol displayed on the touch-sensitive screen.

16. The data entry device of claim 10 , wherein the at least one computer processor generates a second touch instruction to add second fingerprint marks or touch marks to the touch-sensitive screen based on the location of the first touch, and the touch-sensitive screen displays the second touch instruction indicating a second touch location where a user is to touch the touch-sensitive screen to add the second fingerprint marks or touch marks.

17. The data entry device of claim 10 , wherein the touch-sensitive screen receives an authentication code.

18. The data entry device of claim 10 , wherein the data entry device comprises a point of sale device.

19. The data entry device of claim 10 , wherein at least one of the at least one computer processor comprises a touch-sensitive screen controller.
