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

1-25. -25. (canceled)

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

determining personal eye direction trajectories, said 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.

27. The biometric identification and/or authentication method of claim 26, further comprising the step of presenting a pre-defined image to the user, wherein the user is identified and/or authenticated by means of said personal eye movement trajectories being determined while the user is viewing said image.

28. The biometric identification and/or authentication method of claim 27, wherein said image is reproduced with a virtual retinal display.

29. The biometric identification and/or authentication method of claim 26, further comprising the step of presenting an image sequence to the user, wherein said user is identified and/or authenticated by means of personal eye movement trajectories determined while the user is viewing said image sequence.

30. The biometric identification and/or authentication method of claim 29, wherein said image sequence is reproduced with a virtual retinal display.

31. The biometric identification and/or authentication method of claim 26, wherein said eye direction trajectories include saccades.

32. The biometric identification and/or authentication method of claim 26, wherein said eye direction trajectories include determined eye focalization trajectories.

33. The biometric identification and/or authentication method of claim 26, wherein the user is identified and/or authenticated by means of personal variations in the pupil'"'"'s diameter being determined.

34. The biometric identification and/or authentication method of claim 33, wherein said variations are caused through changes in the light conditions.

35. The biometric identification and/or authentication method of claim 33, 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.

36. The biometric identification and/or authentication method of claim 26, wherein said eye movement trajectories take into account eye movement trajectories of both eyes of the user.

37. The biometric identification and/or authentication method of claim 26, wherein said eye movement trajectories are encoded in comparison data and compared with reference data stored in a reference database.

38. The biometric identification and/or authentication method of claim 37, wherein the comparison between said comparison data and said reference data is performed utilizing a Viterbi-grid.

39. The method of claim 26, wherein a parameter dependent on the body temperature is measured and used as an additional authentication parameter.

40. The method of claim 26, wherein a parameter dependent on the warming of the retina is measured and used as an additional authentication parameter.

41. The method of claim 26, wherein a reaction of the iris to light variations is measured and used as an additional authentication parameter.

42. The method of claim 26, wherein said eye movement trajectories are determined through a portable terminal and transmitted through a mobile radio part in said terminal over a mobile radio network to a remote server.

43. The method of claim 42, wherein said server is administered by a service provider and wherein the connection between said mobile radio part and said server is encrypted end-to-end.

44. The method of claim 43, wherein said eye movement trajectories are signed electronically.

45. The method of claim 42, wherein said eye movement trajectories are signed electronically.

46. The method of claim 45, wherein eye movement trajectories are signed electronically with a private key of said user.

47. The method of claim 26, wherein said determining utilizes an eye-movement detection module.

48. A method for identifying and/or authenticating the user of a terminal for a transaction with a server, said terminal comprising a communication part, an eye-movement detection module, and a mobile radio part including a chip-card with a chip-card identification, said method comprising the steps of:

said terminal using said communication part for sending instructions for said transaction over a communication network to said server;

said eye-movement detection module detecting personal eye direction trajectories including involuntary eye movements of the user; and

said server identifying and/or authenticating the user utilizing said chip-card identification and said personal eye direction trajectories.

49. The method of claim 48, wherein said terminal further comprises a virtual retinal display device for displaying an image to the user in support of said detecting step.

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

presenting at least one pre-defined image for viewing by the user;

using an eye-movement detection module for detecting personal eye direction trajectories of the user during said viewing;

identifying and/or authenticating the user by means of said personal eye direction trajectories.

51. The biometric identification and/or authentication method of claim 50, wherein said image is reproduced with a virtual retinal display.

52. The method of claim 50, wherein a sequence of images is presented for viewing by the user.

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

presenting an image to the user;

detecting involuntary movements of the eye of the user, said involuntary movements related to a trajectory of the eye of the user while the user is scanning the image; and

identifying and/or authenticating the user using said detected involuntary movements.

54. The method of claim 55, wherein an eye-movement detection module is used for said detecting.
