Review of Biometric Technologies Used for Atm Security

Biometric recognition refers to an automatic recognition of individuals based on a feature vector(s) derived from their physiological and/or behavioral characteristic. In order to deal with security, Authentication plays an important role. Biometric recognition systems should provide a reliable personal recognition schemes to either confirm or determine the identity of an individual. Applications of such a system include computer systems security, secure electronic banking, mobile phones, credit cards, secure access to buildings, health and social services. By using biometrics a person could be identified based on "who she/he is" rather than "what she/he has" (card, token, key) or "what she/he knows" (password, PIN). We have also outlined opinions about the usability of biometric authentication systems, limitation, comparison between different techniques and their advantages and disadvantages in this paper. Present study deals with new innovative model for biometric ATMs which replace card system by biometric technology for operating ATMs. Proposed model provides high security in authentication which also protects service user from unauthorized access. In this proposed model user required to authenticate himself with biometric identification (Thumb/ Fingerprint/Iris etc.), Personal Identity Number (PIN) and selection of bank branch from displayed list if necessary. These ATMs talk’s to the Farmer in their local languages. This proposed model is designed for the rural farmers, semi-literate peoples. This model reduces complexity with authentication as “authentication is always with you” with high security. It also saves time, cost, and efforts compared with card based ATMs and also saves environmental pollution problem of excess number of plastic cards.
