Review Paper on Various Methods of Implicit Authentication

Abstract

The quest (search) for a reliable and convenient security system to authenticate a computer user has existed since the inadequacy of conventional password mechanism was realized, first by the security community, and then gradually by the public. Verifying the identity of a user before granting access to objects or services is an vital step in nearly all applications or environments. Some applications (e.g. pervasive environment) may impose additional requirements for user authentication mechanism, such as to be continuous and unobtrusive. New system is hoped being transparent and with very minimum user involvement denoted as implicit authentication system. This paper tackles the issue of ambient systems adaptation to users' needs while the environment and users' preferences evolve continuously.
