Commonly used authentication schemes are textual
passwords, graphical passwords and biometrics.
3D password is a multifactor authentication scheme.
To be authenticated, we require a 3D virtual
Combines recognition, recall, token, and biometrics
Users choice to select the type of authentication
e.g : smart card
Fingerprint ,palm prints ,hand geometry ,face
Intrusiveness upon a user’s personal characteristics.
New scheme should combine the existing
Freedom to select the type of authentication
Should provide secrets that are easy to remember,
difficult to guess.
3D PASSWORD SELECTION AND INPUT

User navigate into the 3D virtual environment using
any input device.
The sequence of actions and interactions forms the
users 3D password.

Commonly used authentication schemes are
vulnerable to attacks.
3D Password is a multifactor authentication scheme.
Design of 3D virtual environment, selection of objects
inside the environment, and the object type reflects
the resulted password space.
User’s choice and decision to construct the desired
and preferred 3D password
