Abstract

A gesture-based method is disclosed for authenticating a user. More specifically, the user of an information handling system is prompted to enter a passcode finger tap sequence input gesture via a touch-sensitive device. The finger tap sequence input gesture is processed to generate a passcode finger tap sequence. The passcode finger tap sequence is then compared to a previously-generated authentication finger tap sequence. If the two finger tap sequences match, then the user is authenticated.

Claims

1. A computer-implementable method for authenticating a user, comprising:

generating a request for a finger tap input gesture from a user, the request being displayed within a user interface;

detecting a finger tap sequence input gesture in response to the request;

processing the detected finger tap sequence input gesture to generate a passcode finger tap sequence;

performing comparison operations to compare the authentication finger tap sequence to an authentication finger tap sequence; and

authenticating the user if the passcode finger tap sequence corresponds to the authentication finger tap sequence.

2. The method of claim 1, wherein:

the passcode finger tap sequence comprises a first set of individual finger tap gestures that are sequentially separated by a corresponding first set of time intervals; and

the authentication finger tap sequence comprises a second set of individual finger tap gestures that are sequentially separated by a corresponding second set of time intervals.

3. The method of claim 2, wherein:

the number of individual finger tap gestures in the second set of individual finger tap gestures, and the duration of individual time intervals in the corresponding second set of time intervals, are received as finger tap gesture input data from the user; and

initiation input data is received from the user to initiate processing of the finger tap gesture input data to generate the authentication finger tap sequence.

4. The method of claim 3, wherein:

the comparison operations are performed by respectively comparing the first and second sets of individual finger tap gestures and the first and second sets of time intervals.

5. The method of claim 1, wherein:

the finger tap sequence input gesture is detected by a touch sensitive input device.

6. The method of claim 5, wherein:

the touch sensitive input device comprises at least one of a touch pad and a touch sensitive display device.

7. A system comprising:

a processor;

a data bus coupled to the processor; and

a non-transitory, computer-readable storage medium embodying computer program code, the non-transitory, computer-readable storage medium being coupled to the data bus, the computer program code interacting with a plurality of computer operations and comprising instructions executable by the processor and configured for;

generating a request for a finger tap input gesture from a user, the request being displayed within a user interface;

detecting a finger tap sequence input gesture in response to the request;

processing the detected finger tap sequence input gesture to generate a passcode finger tap sequence;

performing comparison operations to compare the authentication finger tap sequence to an authentication finger tap sequence; and

authenticating the user if the passcode finger tap sequence corresponds to the authentication finger tap sequence.

8. The system of claim 7, wherein:

the passcode finger tap sequence comprises a first set of individual finger tap gestures that are sequentially separated by a corresponding first set of time intervals; and

the authentication finger tap sequence comprises a second set of individual finger tap gestures that are sequentially separated by a corresponding second set of time intervals.

9. The system of claim 8, wherein:

the number of individual finger tap gestures in the second set of individual finger tap gestures, and the duration of individual time intervals in the corresponding second set of time intervals, are received as finger tap gesture input data from the user; and

initiation input data is received from the user to initiate processing of the finger tap gesture input data to generate the authentication finger tap sequence.

10. The system of claim 9, wherein:

the comparison operations are performed by respectively comparing the first and second sets of individual finger tap gestures and the first and second sets of time intervals.

11. The system of claim 7, wherein:

the finger tap sequence input gesture is detected by a touch sensitive input device.

12. The system of claim 11, wherein:

the touch sensitive input device comprises at least one of a touch pad and a touch sensitive display device.

13. A non-transitory, computer-readable storage medium embodying computer program code, the computer program code comprising computer executable instructions configured for:

generating a request for a finger tap input gesture from a user, the request being displayed within a user interface;

detecting a finger tap sequence input gesture in response to the request;

processing the detected finger tap sequence input gesture to generate a passcode finger tap sequence;

performing comparison operations to compare the authentication finger tap sequence to an authentication finger tap sequence; and

authenticating the user if the passcode finger tap sequence corresponds to the authentication finger tap sequence.

14. The non-transitory, computer-readable storage medium of claim 13, wherein:

the passcode finger tap sequence comprises a first set of individual finger tap gestures that are sequentially separated by a corresponding first set of time intervals; and

the authentication finger tap sequence comprises a second set of individual finger tap gestures that are sequentially separated by a corresponding second set of time intervals.

15. The non-transitory, computer-readable storage medium of claim 14, wherein:

the number of individual finger tap gestures in the second set of individual finger tap gestures, and the duration of individual time intervals in the corresponding second set of time intervals, are received as finger tap gesture input data from the user; and

initiation input data is received from the user to initiate processing of the finger tap gesture input data to generate the authentication finger tap sequence.

16. The non-transitory, computer-readable storage medium of claim 15, wherein:

the comparison operations are performed by respectively comparing the first and second sets of individual finger tap gestures and the first and second sets of time intervals.

17. The non-transitory, computer-readable storage medium of claim 13, wherein:

the finger tap sequence input gesture is detected by a touch sensitive input device.

18. The non-transitory, computer-readable storage medium of claim 13, wherein:

the touch sensitive input device comprises at least one of a touch pad and a touch sensitive display device.
