Analysis on various factors affecting the biometrics authentication

Many authentication schemes are being strategized which at least involves minimum two authentication procedures. For instance many multi Factor Based authentication implies that simply authentication mechanism is not sufficient, either serial or parallel implementation of few or best of them is necessary. However many authentication schemes become a success in one case may terribly fail in another. Authentication schemes effectively used by certain set of users are completely ignored or bypassed by another set of users. Hence to have an effective authentication procedure, requirement analysis for authentication has to be done ahead of identifying the schemes. Therefore this work strives to find out the trade-off of various factors that affect the authentication procedure and schemes through analyzing the universal behavior of the users and threats.
