Abstract

An embodiment provides a method, including: detecting, at a touch sensitive surface of an information handling device, user input including at least one multi-touch input; said detecting comprising detecting two or more substantially simultaneous user inputs to the touch sensitive surface; associating, using a processor, a number with the at least one multi-touch input; determining, using the processor, if the user input matches expected user input; and responsive to determining a match, authenticating a user. Other embodiments are described and claimed.

First claim

What is claimed is:

1. A method, comprising:
detecting, at a touch sensitive surface of an information handling device, user input including at least one multi-touch input;
said detecting comprising detecting two or more concurrent user inputs to the touch sensitive surface;
associating, using a processor, a number with the at least one multi-touch input, the number being chosen based on the number of concurrent user inputs;
thereafter performing, using the processor, a comparison of a sequence of numbers associated with a sequence of concurrent user inputs and a predetermined sequence of numbers; and
providing, responsive to determining a match based on the comparison, an authentication of a user.

2. The method of claim 1 , wherein:
said detecting comprising detecting that the user input includes a directional component; and
said performing a comparison includes matching the directional component with an expected directional component.

3. The method of claim 1 , wherein:
said detecting comprising detecting that the user input includes a force component; and
said performing a comparison includes matching the force component with an expected force component.

4. The method of claim 1 , wherein:
said detecting comprising detecting that the user input includes sequential multi-touch input; and
said associating includes associating numbers with each multi-touch input of the sequential multi-touch input.

5. The method of claim 4 , wherein said performing a comparison includes determining that the numbers associated with each multi-touch input occur in an expected sequence.

6. The method of claim 1 , wherein:
said detecting comprising detecting that the user input includes a location component; and
said performing a comparison includes matching the location component with an expected location component.

7. The method of claim 1 , wherein the detecting comprises detecting at least one multi-touch input selected from the group of inputs consisting of a swipe, a tap, and a press and hold.

8. The method of claim 7 , wherein the detected swipe comprises a directional swipe.

9. The method of claim 8 , wherein the detected, directional swipe is selected from the group consisting of a pinch gesture and a zoom gesture.

10. The method of claim 1 , wherein:
said detecting comprising detecting that the user input includes a temporal component; and
said performing includes matching the temporal component with an expected temporal component.

11. An information handling device, comprising:
a touch sensitive surface that accepts user input;
a processor; and
a memory device that stores instructions accessible to the processor, the instructions being executable by the processor to:
detect, at the touch sensitive surface, user input including at least one multi-touch input;
wherein to detect comprises detecting two or more concurrent user inputs to the touch sensitive surface;
associate a number with the at least one multi-touch input, the number being chosen based on the number of concurrent user inputs;
thereafter perform a comparison of a sequence of numbers associated with a sequence of concurrent user inputs and a predetermined sequence of numbers; and
providing, responsive to determining a match based on the comparison, an authentication of a user.

12. The information handling device of claim 11 , wherein:
to detect comprises detecting that the user input includes a directional component; and
to perform a comparison includes matching the directional component with an expected directional component.

13. The information handling device of claim 11 , wherein:
to detect comprises detecting that the user input includes a force component; and
to perform a comparison includes matching the force component with an expected force component.

14. The information handling device of claim 11 , wherein:
to detect comprises detecting that the user input includes sequential multi-touch input; and
to associate includes associating numbers with each multi-touch input of the sequential multi-touch input.

15. The information handling device of claim 14 , wherein to perform a comparison includes determining that the numbers associated with each multi-touch input occur in an expected sequence.

16. The information handling device of claim 11 , wherein:
to detect comprises detecting that the user input includes a location component; and
to perform a comparison includes matching the location component with an expected location component.

17. The information handling device of claim 11 , wherein the detecting comprises detecting at least one multi-touch input selected from the group of inputs consisting of a swipe, a tap, and a press and hold.

18. The information handling device of claim 17 , wherein the detected swipe comprises a directional swipe.

19. The information handling device of claim 18 , wherein the detected, directional swipe is selected from the group consisting of a pinch gesture and a zoom gesture.

20. A product, comprising:
a storage device having processor executable code stored therewith, the code comprising:
code that detects, at a touch sensitive surface of an information handling device, user input including at least one multi-touch input;
wherein to detect comprises detecting two or more concurrent user inputs to the touch sensitive surface;
code that associates, using a processor, a number with the at least one multi-touch input, the number being chosen based on the number of concurrent user inputs;
code that thereafter performs, using the processor, a comparison of a sequence of numbers associated with a sequence of concurrent user inputs and a predetermined sequence of numbers; and
code that provides, responsive to determining a match based on the comparison, an authentication of a user.
