An Overview of Various Human Traits Used for Biometric Recognition

With the advent of technology, almost all the precious assets of humans have gone digitized. This digital treasure needs to be securely stored and access to it must be restricted to the owner or trusted personals only. With this security urgency, there appeared the biometric solutions, which are fast, reliable and highly secure as compared to traditional physical security solutions. These biometric systems exploit the unique physiological and behavioural traits of humans for recognition and authorization. This paper is a small attempt to summarize the commonly used and intended to be used biometric traits. The merits and demerits of some of the biometric traits is being discussed in this paper.
