Abstract

There is provided an information processing device, information processing method, and program capable of realizing the authentication with high security using the movement of line of sight, the information processing device including: a line-of-sight movement identification unit configured to identify movement of line of sight of a user to a body of the user on a basis of an image of an eye of the user and an image of the body of the user positioned in a line-of-sight direction of the user, captured by an imaging unit; and a user authentication unit configured to authenticate the user on a basis of the identified movement of line of sight.

Claims

1. An information processing device comprising:

a line-of-sight movement identification unit configured to identify movement of line of sight of a user to a body of the user on a basis of an image of an eye of the user and an image of the body of the user positioned in a line-of-sight direction of the user, captured by an imaging unit; and

a user authentication unit configured to authenticate the user on a basis of the identified movement of line of sight.

2. The information processing device according to claim 1, further comprising:

a line-of-sight pattern comparison unit configured to compare a line-of-sight pattern registered with a database in association with the user with a line-of-sight pattern based on the movement of line of sight of the user identified by the line-of-sight movement identification unit,

wherein the user authentication unit authenticates the user on a basis of a comparison result of the line-of-sight pattern comparison unit.

3. The information processing device according to claim 2,

wherein the user authentication unit determines that the user is a valid user in a case where a matching degree of the line-of-sight pattern determined by the line-of-sight pattern comparison unit is a predetermined threshold or more.

4. The information processing device according to claim 2, further comprising:

a physical characteristics detection unit configured to detect physical characteristics on a part of the body of the user on a basis of the image of the body of the user,

wherein the line-of-sight movement identification unit identifies the movement of line of sight of the user to the body of the user on a basis of the image of the eye of the user and the detected physical characteristics.

5. The information processing device according to claim 2,

wherein the line-of-sight pattern is a pattern of a line-of-sight operation to one or more regions of the body of the user.

6. The information processing device according to claim 5,

wherein the line-of-sight pattern registered with the database is a pattern of a line-of-sight operation to each of one or more regions of the body of the user associated with an order of movement of the line of sight.

7. The information processing device according to claim 5,

wherein the line-of-sight pattern registered with the database is a pattern of a line-of-sight operation to each of one or more regions of the body of the user associated with an order of change of a posture of the body of the user.

8. The information processing device according to claim 5,

wherein the line-of-sight operation includes gaze to a region of the body of the user or a trace of line of sight.

9. The information processing device according to claim 4,

wherein the physical characteristics include a position or a shape of a mole, a wrinkle, or a vascular pattern.

10. The information processing device according to claim 1, further comprising:

a display control unit configured to cause a display unit to sequentially display indication of the identified movement of line of sight each time the line-of-sight movement identification unit identifies the movement of line of sight.

11. The information processing device according to claim 10, further comprising:

the display unit.

12. The information processing device according to claim 1,

wherein the imaging unit includes a first imaging unit configured to capture the image of the eye of the user and a second imaging unit configured to capture the image of the body of the user positioned in the line-of-sight direction of the user.

13. The information processing device according to claim 1,

wherein the information processing device is an eyeglass-type device.

14. An information processing method comprising:

identifying movement of line of sight of a user to a body of the user on a basis of an image of an eye of the user and an image of the body of the user positioned in a line-of-sight direction of the user, captured by an imaging unit; and

authenticating the user on a basis of the identified movement of line of sight.

15. A program causing a computer to function as:

a line-of-sight movement identification unit configured to identify movement of line of sight of a user to a body of the user on a basis of an image of an eye of the user and an image of the body of the user positioned in a line-of-sight direction of the user, captured by an imaging unit; and

a user authentication unit configured to authenticate the user on a basis of the identified movement of line of sight.
