Claim Text:
1. An authentication system, comprising: an ocular sensor configured to sense an eye of a first user and to provide data indicating a location at which the eye is looking and a size of a pupil of the eye; memory for storing predefined parameters associated with the first user, the predefined parameters including first fixation parameters and first saccade parameters, the first fixation parameters indicative of eye movement characteristics and pupil size change characteristics for an eye of an authorized user during periods of fixation, the first saccade parameters indicative of eye movement characteristics and pupil size change characteristics for the eye of the authorized user during periods of saccade; and logic configured to calculate a plurality of parameters based on the data and to identify periods of fixation and periods of saccade for the eye of the first user based on the data, the plurality of parameters including second fixation parameters and second saccade parameters, the second fixation parameters indicative of eye movement characteristics and pupil size change characteristics for the eye of the first user during the identified periods of fixation, the second saccade parameters indicative of eye movement characteristics and pupil size change characteristics for the eye of the first user during the identified periods of saccade, the logic configured classify each of the plurality of parameters as occurring during a respective one of the identified periods of fixation or as occurring during a respective one of the identified periods of saccade, the logic further configured to perform, based on classification, by the logic, of the plurality of parameters as occurring during the identified periods of fixation or the identified periods of saccade, (1) first comparisons between the first fixation parameters and the second fixation parameters and (2) second comparisons between the first saccade parameters and the second saccade parameters, the logic further configured to authenticate the first user based on the first comparisons and the second comparisons.
