METHOD FOR USING EYE TRACKING AND EYE BIOMETRICS FOR AUTHENTICATION
The invention is a method for authenticating a system user based on eye tracking or eye parameters.
1 . A method comprising:
Retrieving a set of one or more pre-computed stored eye tracking calibration parameters;
Using said calibration parameters to determine a gaze area;
Calculating a distance between said gaze area and the unlock area of a display screen;
Comparing said distance to a predetermined threshold value.
2 . A method as in claim 1 , further comprising:
Authenticating and unlocking a system if said distance is less than said threshold value, and rejecting access otherwise.
3 . A method as in claim 2 further comprising:
Determining whether a second authentication criterion has been met;
Keeping said system locked if said second authentication criterion has not been met.
4 . A method as in claim 1 further comprising:
Computing one or more said eye tracking calibration parameters during a calibration procedure.
5 . A method as in claim 1 further comprising:
Computing one or more said eye tracking calibration parameters during system use.
6 . A method as in claim 1 further comprising:
Updating one or more said eye tracking calibration parameters after a successful authentication.
7 . A method comprising:
Retrieving a set of one or more pre-computed stored user eye parameters;
Measuring current user eye parameters;
Comparing said stored eye parameters to said current user eye parameters;
Determining if said current user eye parameters match said stored eye parameters within a predetermined similarity threshold value.
8 . A method as in claim 7 further comprising:
Authenticating and unlocking said system if said current user eye parameters equal or exceed said predetermined similarity threshold value, and rejecting access otherwise.
9 . A method as in claim 8 further comprising:
Determining whether a second authentication criterion has been met;
Keeping said system locked if said second authentication criterion has not been met.
10 . A method as in claim 7 further comprising:
Computing one or more said eye parameters during a calibration process.
11 . A method as in claim 7 further comprising:
Computing one or more said eye parameters while the system is being used.
12 . A method as in claim 7 further comprising:
Updating one or more said eye parameters are updated after a successful authentication of the user.
