Abstract

A method and apparatus for providing authentication using an adaptive liquid lens are disclosed. For example, in one embodiment, the method receives a request for authentication from a mobile endpoint device of a user, wherein the request comprises a first retinal image of the user captured using an adaptive liquid lens of the mobile endpoint device. The method obtains a second retinal image of the user, wherein the second retinal image is a stored retinal image of the user. The method authenticates the first retinal image against the second retinal image. In another embodiment, the method captures a first retinal image of a user via a mobile endpoint device of the user, wherein the mobile endpoint device comprises an adaptive liquid lens. The method then sends a request for authentication from the mobile endpoint device over a network, wherein the request comprises the first retinal image.

Claims

1. A system for authenticating a first retinal image in a network, comprising:

a processor; and

a computer-readable medium storing a plurality of instructions which, when executed by the processor, cause the processor to perform operations, the operations comprising;

receiving a request for authentication from a mobile endpoint device of a user, wherein the request comprises the first retinal image of the user captured using an adaptive liquid lens and a second lens of the mobile endpoint device, wherein the first retinal image of the user comprises a near-field image;

obtaining a second retinal image of the user, wherein the second retinal image is a stored retinal image of the user; and

authenticating the first retinal image against the second retinal image.

2. The system of claim 1, wherein the operations further comprise:

providing a positive response to the mobile endpoint device when the request for authentication is successful; and

providing a negative response to the mobile endpoint device when the request for authentication has failed.

3. The system of claim 1, wherein the second lens comprises a fixed camera lens, wherein the adaptive liquid lens and the fixed camera lens are used to perform near field imaging.

4. The system of claim 1, wherein the mobile endpoint device comprises a mobile phone.

5. The system of claim 4, wherein the user is a subscriber of a network service provided by a service provider of the network.

6. The system of claim 5, wherein the authenticating is performed by the service provider.

7. The system of claim 1, wherein the authenticating is performed by a third party.

8. The system of claim 1, wherein the mobile endpoint device uses infrared radiation for illumination of a retina of the user in capturing the first retinal image.

9. A mobile endpoint device for sending a request for authentication, comprising:

a processor; and

a computer-readable medium storing a plurality of instructions which, when executed by the processor, cause the processor to perform operations, the operations comprising;

capturing a first retinal image of a user via an adaptive liquid lens and a second lens, wherein the first retinal image of the user comprises a near-field image; and

sending the request for authentication from the mobile endpoint device over a network, wherein the request comprises the first retinal image.

10. The mobile endpoint device of claim 9, further comprising:

receiving a positive response over the network when the request for authentication is successful; and

receiving a negative response over the network when the request for authentication has failed.

11. The mobile endpoint device of claim 10, wherein the authentication is performed by obtaining a second retinal image of the user, wherein the second retinal image is a stored retinal image of the user, and authenticating the first retinal image against the second retinal image.

12. The mobile endpoint device of claim 9, wherein the second lens comprises a fixed camera lens, wherein the adaptive liquid lens and the fixed camera lens are used to perform near field imaging.

13. The mobile endpoint device of claim 9, wherein the mobile endpoint device comprises a mobile phone.

14. The mobile endpoint device of claim 13, wherein the user is a subscriber of a network service provided by a service provider of the network.

15. The mobile endpoint device of claim 14, wherein the request for authentication is processed by the service provider.

16. The mobile endpoint device of claim 9, wherein the request for authentication is processed by a third party.

17. The mobile endpoint device of claim 9, wherein the mobile endpoint device uses infrared radiation for illumination of a retina of the user in capturing the first retinal image.

18. A non-transitory computer-readable storage medium storing a plurality of instructions which, when executed by a processor, cause the processor to perform operations for authenticating a first retinal image, the operations comprising:

receiving a request for authentication from a mobile endpoint device of a user, wherein the request comprises the first retinal image of the user captured using an adaptive liquid lens and a second lens of the mobile endpoint device, wherein the first retinal image of the user comprises a near-field image;

obtaining a second retinal image of the user, wherein the second retinal image is a stored retinal image of the user; and

authenticating the first retinal image against the second retinal image.

19. The non-transitory computer-readable storage medium of claim 18, wherein the operations further comprise:

providing a positive response to the mobile endpoint device when the request for authentication is successful; and

providing a negative response to the mobile endpoint device when the request for authentication has failed.

20. The non-transitory computer-readable storage medium of claim 18, wherein the second lens comprises a fixed camera lens, wherein the adaptive liquid lens and the fixed camera lens are used to perform near field imaging.
