IDENTIFICATION APPROACH FOR BIOMETRIC SYSTEMS USING THE ABM PROCEDURE WITH THE LOW FREQUENCY EYE TRACKER

Biometric Systems Now a Days are playing a vital role in the whole word. Biometric Identification is been carried out in all the industrics, Institutions and in all the concerns wherr we are in need of the security and heavy monitoring. There are various traints considered for identifying and Authenticating the individual persons, they may include the behaviourial and also the physiological traits. Eye tracking is the process of measuring either the point of gaze (where one islooking) or the motion of an eye relative to the head. An eye tracker is a device for measuring eye positions and eye movement. Eye trackers are used in research on the visual system. This paper focuses on the identification with low frequency Eye Tracker. he most widely used current designs are video-based eye trackers. A camera focuses on one or both eyes and records their movement as the viewer looks at some kind of stimulus. Most modern eye-trackers use the center of the pupil and infrared / near-infrared non-collimated light to create cornealreflections(CR). The vector between the pupil center and the cornealreflections can be used to compute the point of regard on surface or the gaze direction. A simple calibration procedure of the individual is usually needed before using the eye tracker. This paper presents a review of the related works in the field as well as a general classification of dif erent identification types. We stated a formal description of a saccade and an analyzed fragment of the gaze trajectory containing a saccade, which is based on the finite dif erences method, and revealed features of the eye movements that can be used for the identification purpose. Two classifiers are proposed and compared based on the experimental results obtained for them and we examined whether the delivery of an attentional bias modification (ABM) procedure in the presleep period could produce transient benefits for sleep-disturbed individuals by reducing presleep cognitive arousal and improving ease of sleep onset. In a counterbalanced repeated A-B design, participants alternated completing an These results suggest that delivery of ABM can attenuate cognitive arousal and sleep onset latency and highlights the possibility that targeted delivery of ABM could deliver real- world benefits for sleep-disturbed individuals.
