Method and Apparatus for Performing Authentication

1 . An apparatus, comprising:

at least one processor;

at least one memory including computer program code, the memory and the computer program code configured to, working with the processor, cause the apparatus to perform at least the following:

determining at least one three dimensional representation of at least one object proximate to the apparatus; and

performing authentication, the authentication comprising:

a first authentication based, at least in part, on the three dimensional representation; and

a second authentication that is independent of the three dimensional representation.

2 . The apparatus of claim 1 , wherein performing authentication comprises:

determining a correspondence between the three dimensional representation and at least part of object authentication information; and

determining successful authentication based at least in part on the correspondence.

3 . The apparatus of claim 1 , wherein the second authentication is based, at least in part, on a different three dimensional representation of a different object.

4 . The apparatus of claim 1 , wherein the second authentication comprises:

determining a correspondence between a motion associated with the object and at least part of motion authentication information; and

determining successful authentication based at least in part on the correspondence.

5 . The apparatus of claim 1 , wherein performing authentication comprises determining successful authentication based, at least in part, on determination that the first authentication was successful and the second authentication was successful.

6 . The apparatus of claim 1 , wherein the three dimensional representation is indicative of the object being a hand performing input on the apparatus.

7 . The apparatus of claim 1 , wherein the three dimensional representation comprises at least one indication of an adornment on the hand.

8 . The apparatus of claim 1 , the memory further including computer program code configured to cause the apparatus to perform:

receiving sensor information indicative of the object;

determining the three dimensional representation based, at least in part, on the sensor information;

receiving sensor information indicative of movement of the apparatus with respect to the object;

receiving additional sensor information; and

determining another three dimensional representation based at least in part on the three dimensional information, the sensor information, and the sensor information indicative of movement, wherein the authentication is based, at least in part on the other three dimensional representation.

9 . The apparatus of claim 1 , wherein the apparatus is a mobile phone.

10 . A method comprising:

determining at least one three dimensional representation of at least one object proximate to an apparatus; and

performing authentication, the authentication comprising:

a first authentication based, at least in part, on the three dimensional representation; and

a second authentication that is independent of the three dimensional representation.

11 . The method of claim 10 , wherein performing authentication comprises:

determining a correspondence between the three dimensional representation and at least part of object authentication information; and

determining successful authentication based at least in part on the correspondence.

12 . The method of claim 10 , wherein the second authentication is based, at least in part, on a different three dimensional representation of a different object.

13 . The method of claim 10 , wherein the second authentication comprises:

determining a correspondence between a motion associated with the object and at least part of motion authentication information; and

determining successful authentication based at least in part on the correspondence.

14 . The method of claim 10 , wherein performing authentication comprises determining successful authentication based, at least in part, on determination that the first authentication was successful and the second authentication was successful.

15 . The method of claim 10 , wherein the three dimensional representation is indicative of the object being a hand performing input on the apparatus.

16 . The method of claim 10 , further comprising:

receiving sensor information indicative of the object;

determining the three dimensional representation based, at least in part, on the sensor information;

receiving sensor information indicative of movement of the apparatus with respect to the object;

receiving additional sensor information; and

determining another three dimensional representation based at least in part on the three dimensional information, the sensor information, and the sensor information indicative of movement, wherein the authentication is based, at least in part on the other three dimensional representation.

17 . At least one computer-readable medium encoded with instructions that, when executed by a computer, perform:

determining at least one three dimensional representation of at least one object proximate to an apparatus; and

performing authentication, the authentication comprising:

a first authentication based, at least in part, on the three dimensional representation; and

a second authentication that is independent of the three dimensional representation.

18 . The medium of claim 17 , wherein performing authentication comprises:

determining a correspondence between the three dimensional representation and at least part of object authentication information; and

determining successful authentication based at least in part on the correspondence.

19 . The medium of claim 17 , wherein the second authentication is based, at least in part, on a different three dimensional representation of a different object.

20 . The medium of claim 17 , wherein the second authentication comprises:

determining a correspondence between a motion associated with the object and at least part of motion authentication information; and

determining successful authentication based at least in part on the correspondence.
