摘要:In today’s world, security is important aspect in day to day life.So, everyone used various ways for security purpose. People use passwords for their security.Generally, everyone uses textual password. Textual password is combination of alphabets and numbers. People keep textual password as name of their favorite things, actors or actress, dish and meaningful word from dictionary. But the person who is very close to that person can easily gues the password. Graphical password is advanced version of password. Graphical passwords have received considerable attention lately as Potential alternatives to text-based passwords. Graphical password is composed of images, parts of images, or sketches[4]- [7]. These passwords are very easy to use and remember. Biometric password is an extended feature of graphical passwords. Biometric password is consisting of face recognition, thumb impression, eye retina and heartbeats pulses[10]. In this paper, we present and evaluate our contribution, i.e., the 3-D password. The 3-D password is a multifactor authentication scheme. To be authenticated, we present 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[10].
