This document discusses 3D password authentication. It introduces 3D passwords as a multifactor authentication scheme that combines recognition, recall, tokens and biometrics. It describes the functionalities required, including selecting authentication techniques and secrets that are easy to remember but hard to guess. The document outlines guidelines for designing virtual environments for 3D password input and lists applications like critical servers and military facilities.

2. Topic of overview
 Introduction
 Authentication schemes
 Functionalities required
 3D password selection and input
 Virtual environment design guidelines
 Applications
 Security analysis
 Advantages & disadvantages

3. Introduction
 Commonly 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.

5. Authentication Schemes
(1) Knowledge Based
(2) Token Based
(3) Biometric Based

6. Knowledge based
Password
 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.

9. 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.

10. 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.

11. 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.

12. Application
 Critical servers.
 Nuclear & military facilities.
 Airplanes & jet fighters.
 ATM, desktop computers & laptops.

14. Disadvantages
 Difficult for blind people to use this technology.
 Requires sophisticated computers technology expensive.
 A lot of program coding is required.
