Minimum Space and Huge Security in 3D Password Scheme

Abstract

D password is a multifactor authentication scheme. For the authentication, it is require to presents a 3-D virtual environment where the user navigates and interacts with various objects. The sequence of actions and interactions toward the objects inside the 3-D environment constructs the user's 3-D password. The 3-D password can combine most existing authentication schemes such as textual passwords, graphical passwords, and various types of biometrics into a 3- D virtual environment. The design of the 3-D virtual environment and the type of objects selected determine the 3- D password key space. As per the reference(1) the author tells that the resulting 3D password space is very huge. In this paper we shows that the space is reduced and increase the security.
