IntroductionCommonly used authentication schemes are textual passwords,

graphical passwords and biometrics.

3D password is a multifactor authentication scheme.

To be authenticated, we require 3D virtual environment.

combines recognition, recall, token and biometrics based systems.

Users choice to select the type of authentication technique.

Authentication Schemes

(1) Knowledge Based

(2) Token Based

(3) Biometric Based

Knowledge basedPassword Password is basically an

encryption algorithms.

It is 8-15 character or slightly more than that.

Mostly textual passwords now a days are kept which are very simple.

Functionalities Required

New scheme should combine the existing authentication schemes.

Freedom to select the type of authentication techniques.

Should provide secrets that are easy to remember, difficult to guess.

3D Password Selection & Input

3D environment space represented by the co-ordinates.

User navigate into the 3D virtual environment using any input device.

The sequence of actions and interaction forms the user 3D password.

3D Virtual Environment 3D virtual environment

affects the usability, effectiveness & acceptability of a 3D password system.

3D environment reflects the administration needs the security requirements.

Application

Critical servers.

Nuclear & military facilities.

Airplanes & jet fighters.

ATM, desktop computers & laptops.

Disadvantages

Difficult for blind people to use this technology.

Requires sophisticated computers technology expensive.

A lot of program coding is required.
