Biometric system is useful to identify person. Biometric systems are rising and generally used technology. Because of this generalization today many protected systems are taking advantage of biometric systems. And one of these newest research areas of biometric systems is gait analysis systems. Numerous locations, including banks, airports, courtrooms for criminal proceedings, and security reasons, require the biometric technology. We can recognize a person by their fingerprints, handprints, eyes (retina), and face with the use of a biometric system . The issue of walking behavior is addressed through the use of gait technology. In security and video surveillance applications, gait identification is crucial. A person's lack of walking style may be resolved by reorganizing the gait. Gait biometric skill recognizes a individual by the walking pattern. Gait study investigates human body parts to find personal features for human recognition. Gait technology recognizes person walking pattern for individual detection. When person identification ratio matches up to 60% to 70% in order to that here Re-identification is solution. Several studies on this study area are examined during the survey.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
