Patent ID: 7986816

Claim:
A method for multiple factor authentication of a user comprising: a. performing, by a computer, iris recognition for user authentication; b. performing, by the computer, biometric eye tracking for user authentication; c. performing, by the computer, password entry via eye tracking for user authentication, wherein performing password entry via eye tracking for user authentication comprises; determining a plurality of estimated locations where an eye of the user is focused in a series, receiving data associated with the plurality of estimated locations, comparing the received data with a reference password, implementing error correction, wherein the implementing error correction comprises, determining whether the plurality of estimated locations follows a pattern that comprises k<S occurrences of event A and S−k occurrences of event N, wherein k is the number of locations correctly identified by the user, S is the total number of the plurality of estimated locations, A is an event wherein the estimated location is at a correct location, and N is an event wherein the estimated location is at a neighbor location, determining an authentication probability given by p A ⁡ ( k ) = p ⁡ ( k ) p ⁡ ( s ) , comparing the authentication probability to a probability that the occurrence of the pattern is due to a random try, and successfully authenticating the user if the authentication probability is greater than the probability that the occurrence of the pattern is due to a random try, successfully authenticating, by the computer, the user if the received data matches the reference password; and d. authenticating, by the computer, the user upon successful authentication of a-c.
