Abstract

Biometric identification and/or authentication method for identifying and/or authenticating the user (1) of a terminal (2), wherein said user is identified and/or authenticated by means of personal involuntary eye movement patters being determined with an eye-movement detection module (20).

The user is identified and/or authenticated for example by means of characteristics of the personal trajectory (51) of the eyes on an image being determined.

Claims

1. A biometric identification and/or authentication method for identifying and/or authentication the user of a terminal, said method comprising the steps of:

utilizing an eye movement detection module for determining personal eye direction trajectories, said trajectories including involuntary eye movements of an eye of the user; and

identifying and/or authenticating the user using said personal eye direction trajectories, wherein

said user is identified and/or authenticated by means of determining personal blinking movement trajectories.

2. The biometric identification and/or authentication method of claim 1, wherein at least one pre-defined image is presented to the user, and wherein the user is determined by means of personal eye movement trajectories being determined while viewing said image.

3. The biometric identification and/or authentication method of claim 1, wherein an image sequence is presented to the user and wherein said user is determined by means of personal eye movement trajectories being determined while viewing said image sequence.

4. The biometric identification and/or authentication method of claim 2, wherein said image is reproduced with a virtual retinal display.

5. The biometric identification and/or authentication method of claim 1, wherein said eye direction trajectories include saccades.

6. The biometric identification and/or authentication method of claim 1, wherein the user is identified and/or authenticated by means of eye focalization trajectories being determined.

7. The biometric identification and/or authentication method of claim 1, wherein the user is identified and/or authenticated by means of personal variations in the pupil'"'"'s diameter being determined.

8. The biometric identification and/or authentication method of claim 7, wherein said variations are caused through changes in the light conditions.

9. The biometric identification and/or authentication method of claim 7, wherein at least one pre-defined image sequence is presented to the user and wherein said user is identified and/or authenticated by means of determining said variations when the image changes.

10. The biometric identification and/or authentication method of claim 1, wherein said blinking movements are caused through changes in the light conditions.

11. The biometric identification and/or authentication method of claim 1, wherein at least one pre-defined image sequence is presented to the user and wherein said user is identified and/or authenticating by means of determining said blinking movements when the image changes.

12. A biometric identification and/or authentication method for identifying and/or authenticating the user of a terminal, said method comprising the steps of:

utilizing an eye-movement detection module for determining personal eye direction trajectories, said trajectories including involuntary eye movements of an eye of the user; and

identifying and/or authenticating the user using said personal eye direction trajectories, wherein

a parameter dependent on the warming of the retina is measured and used as an additional authentication parameter.

13. A biometric identification and/or authentication method for identifying and/or authenticating the user of a terminal, said method comprising the steps of:

utilizing an eye-movement detection module for determining personal eye direction trajectories, said trajectories including involuntary eye movements of an eye of the user; and

identifying and/or authenticating the user using said personal eye direction trajectories, wherein

the reaction of the iris to light variations is measured and used as an additional authentication parameter.

14. A biometric identification and/or authentication method for identifying and/or authenticating the user of a terminal, said method comprising the steps of:

utilizing an eye-movement detection module for determining personal eye direction trajectories, including involuntary eye movements of an eye of the user; and

identifying and/or authenticating the user using said personal eye direction trajectories, wherein

said user is identified and/or authenticated by means of determining personal blinking movement trajectories.

15. The biometric identification and/or authentication method of claim 14, wherein said blinking movements are caused through changes in the light conditions.

16. The biometric identification and/or authentication method of claim 14, wherein at least one pre-defined image sequence is presented to the user and wherein said user is identified and/or authenticated by means of determining said blinking movements when the image changes.

17. A biometric identification and/or authentication method for identifying and/or authenticating the user of a terminal, said method comprising the steps of:

utilizing an eye-movement detection module for determining personal eye direction trajectories including involuntary eye movements of an eye of the user; and

identifying and/or authenticating the user using said personal eye direction trajectories, wherein

a parameter dependent on the warming of the retina is measured and used as an additional authentication parameter.

18. A biometric identification and/or authentication method for identifying and/or authenticating the user of a terminal, said method comprising the steps of:

utilizing an eye-movement detection module for determining personal eye direction trajectories including involuntary eye movements of an eye of the user; and

identifying and/or authenticating the user using said personal eye direction trajectories, wherein

the reaction of the iris to light variations is measured and used as an additional authentication parameter.
