Abstract: Gait Analysis is a new profound human sensor which focuses on human locomotion. The word ‘gait’ means the manner of walking. It is a highly secured technique in which a person’s gait is stored offline in a database and for security reasons the previous data is matched with the present one in order to grant access to a highly secured area. Before considering human locomotion, many other parameters like age, height, weight, health, speed etc. are taken into account. This paper focuses on how Gait Analysis can be used in the field of security in comparison with other existing techniques. Previously and presently, Gait Analysis is being used in animation movie making, visual world creation etc. Its use can be expanded to various other fields like medical sciences, biometric identification etc. in order to provide benefit to the human beings.
