3D Password Advance Authentication Systems


Current authentication systems suffer from many
weaknesses. Textual passwords are commonly used; however,
users do not follow their requirements. Users tend to choose
meaningful words from dictionaries, which make textual passwords
easy to break and vulnerable to dictionary or brute force
attacks. Many available graphical passwords have a password
space that is less than or equal to the textual password space.
Smart cards or tokens can be stolen. Many biometric authentications
have been proposed; however, users tend to resist using
biometrics because of their intrusiveness and the effect on their
privacy. Moreover, biometrics cannot be revoked. 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.
