Based on the available literature such as papers, technical reports, evaluative studies, manufacturers and designer claims it will set selection criteria, define threats, evaluate biometric methods, and list their present and future applications. Approach Identification is the process whereby an identity is assigned to a specific individual. There is a variety of means for identifying a person's identity e.g. appearance, social behavior, name, codes, knowledge, bio-dynamics, natural physiography.
Authentication is the process designed to verify a user's identity.
The goal of authentication is to protect a system against unauthorized use. This feature enables also the protection of subscribers by denying the possibility for intruders to impersonate authorized users. Additional convenient security barriers are needed as our society gets more and more computer dependent. Biometrics provide an answer to this need since the uniqueness of an individual arises from his personal or behavior characteristics with no passwords or numbers to remember. Threats based on the security objectives of identification and authentication will be described and a list of applicability criteria will be presented.
