摘要：User authentication systems aretraditionally based on pairs of username and password andverify theidentity of the user only at login phase. No checksare performed during working sessions, which are terminatedby anexplicit logout or expire after an idle activityperiod of the user.Emerging biometric OTP generation, question andanswers solutions allow substituting username and password with data during session establishment, but in such anapproach still a single verification is deemed sufficient, and the identity of a user is considered immutable during theentire session. Additionally in this system we are going to implement the session authentication with various approachlike biometric, OTP(one time password) generation, question and answers with specified time limiting. A secureprotocol is defined for perpetual authentication through continuous user verification. The protocol determines adaptivetime outs based on the quality, frequency and type of biometric, OTP generation, question. And answers datatransparently acquired from the user.
