Abstract

Certain aspects of a device and method for authenticating a user are disclosed. The device may display a first set of images and receive a user input. The received user input may comprise a set of gestures and a selection of a plurality of images from the first set of images in a pre-determined sequence. The selected plurality of images may be modified based on the set of gestures. The device compares the modified selected plurality of images with a second set of pre-stored images. The device may authenticate the user based on the comparison.

Claims

1. A method for authenticating a user, said method comprising:

displaying a first set of images on a device;

receiving a user input, wherein said received user input comprises a set of gestures and a selection of a plurality of images from said first set of images in a pre-determined sequence, wherein said selected said plurality of images are modified based on said set of gestures;

comparing said modified said selected said plurality of images with a second set of pre-stored images; and

authenticating said user based on said comparing.

2. The method of claim 1, wherein said device is one of:

a touch screen device, a tablet, a personal digital assistant (PDA), a touchpad device, a smartphone, or a desktop monitor.

3. The method of claim 1, wherein said set of gestures comprises one or more of:

hand gestures, finger gestures, facial gestures and/or body gestures.

4. The method of claim 1, wherein said user input further comprises speech input.

5. The method of claim 1, wherein said modification of said selected said plurality of images comprises one or more of:

rotating one or more of said selected said plurality of images, flipping one or more of said selected said plurality of images, clipping one or more of said selected said plurality of images, and/or generating a collage of one or more of said selected said plurality of images.

6. The method of claim 5, wherein said collage is generated based on selection and combination of said one or more of said selected said plurality of images in said pre-determined sequence, position or shape.

7. The method of claim 1, comprising receiving from said user said second set of pre-stored images during a configuration of said device.

8. The method of claim 7, comprising storing in a memory, said second set of pre-stored images in said pre-determined sequence during said configuration of said device.

9. The method of claim 8, comprising receiving from said user a degree of complexity for one or more applications during said configuration of said device.

10. The method of claim 1, wherein said authenticating comprises enabling said user to perform one or more activities, said one or more activities correspond to one or more of:

locking said device, locking one or more features of said device, locking one or more applications of said device, unlocking said device, unlocking one or more features of said device, unlocking one or more applications of said device, and/or launching one or more applications in said device.

11. A device for user authentication, said device comprising:

one or more processors in said device, said one or more processors being operable to;

display a first set of images on said device;

receive a user input, wherein said received user input comprises a set of gestures and a selection of a plurality of images from said first set of images in a pre-determined sequence, wherein said selected said plurality of images are modified based on said set of gestures;

compare said modified said selected said plurality of images with a second set of pre-stored images; and

authenticate said user based on said comparison;

12. The device of claim 11, wherein said modification of said selected said plurality of images comprises one or more of:

rotating one or more of said selected said plurality of images, flipping one or more of said selected said plurality of images, clipping one or more of said selected said plurality of images, and/or generating a collage of one or more of said selected said plurality of images.

13. The device of claim 12, wherein said collage is generated based on selection and combination of said one or more of said selected said plurality of images in a pre-determined sequence, position or shape.

14. A method for authenticating a user, said method comprising:

displaying a set of images to a user on a device, wherein at least a portion of said set of images comprises alphanumeric text;

receiving a user input, wherein said received user input comprises a selection of a plurality of images from said displayed set of images in a pre-determined sequence;

extracting said alphanumeric text in a sequence from said selected said plurality of images;

comparing said sequence of said extracted alphanumeric text with a pre-stored sequence of alphanumeric text; and

authenticating said user based on said comparing.

15. The method of claim 14, wherein said user input further comprises a set of gestures for selecting said plurality of images, said set of gestures comprises one or more of:

hand gestures, finger gestures, facial gestures and/or body gestures.

16. A device to authenticate a user, said device comprising:

one or more processors in said device, said one or more processors being operable to;

display a set of images to a user on a device, wherein at least a portion of said set of images comprises alphanumeric text;

receive a user input, wherein said received user input comprises a selection of a plurality of images from said displayed set of images in a pre-determined sequence;

extract said alphanumeric text from said selected said plurality of images;

compare said sequence of said extracted alphanumeric text with a pre-stored sequence of alphanumeric text; and

authenticate said user based on said comparison.

17. A method for authenticating a user, said method comprising:

displaying a first set of images on a device and a pre-stored message;

receiving a user input, wherein said received user input comprises a set of gestures and a selection of a plurality of images from said first set of images in a pre-determined sequence based on said set of gestures and said pre-stored message;

comparing said selected said plurality of images with a second set of pre-stored images corresponding to said pre-stored message; and

authenticating said user based on said comparing.

18. The method of claim 17, wherein a plurality of images in said second set of pre-stored images is associated with said pre-stored message.

19. The method of claim 18, comprising associating said plurality of images in said second set of pre-stored images with said pre-stored message during a configuration of said device.

20. The method of claim 18, wherein said plurality of images in said second set of pre-stored images includes a plurality of personal images uploaded by said user.

21. The method of claim 17, wherein said authenticating comprises enabling said user to perform one or more activities, said one or more activities correspond to one or more of:

locking said device, locking one or more features of said device, locking one or more applications of said device, unlocking said device, unlocking one or more features of said device, unlocking one or more applications of said device, and/or launching one or more applications of said device.
