3D PASSWORD: A COMPLEX AUTHENTICATION MECHANISM
Keywords:Authentication, Virtual environment, password
Authentication is a process of validating a user and providing security to a system. Authentication mechanisms include textual passwords, biometric passwords, site key validation etc. each having some limitations and drawbacks. To overcome these drawbacks, 3D-password came into picture as a new and improved authentication scheme. 3D-password is a multi-factor authentication scheme which includes the previous authentication schemes such as textual passwords, graphical passwords, biometric passwords etc., and adds a third dimension of a virtual environment to the previously available authentication scheme. As adding a third dimension to a picture increases its complexity, similarly adding a third dimension to the passwords makes it more complex. In this paper we explain what 3D-password is, how it is used and applied for authentication.
