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 a 3D virtual environment.

4. Combines recognition, recall, token and biometrics
based system.
Users choice to select the type of authentication
technique.

5. AUTHENTICATION SCHEMES
 KNOWLEDGE BASED
- Recall based
- Recognition based
 TOKEN BASED
e.g : smart card

6.  BIOMETRIC BASED
- Fingerprint, palm prints, hand geometry, face
recognition
 GRAPHICAL PASSWORD
- Recognition based
- Recall based

7. FUNCTIONALITIES REQUIRED
 New scheme should combine the existing authentication
schemes.
 Freedom to select the type of authentication technique.
 Should provide secrets that are easy to remember, difficult
to guess.

8. 3D PASSWORD SELECTION AND 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 interactions forms the users
3D password.

9. 3D VIRTUAL ENVIRONMENT DESIGN
GUIDELINES
 Real-life similarity
 Object uniqueness and distinction
 Three-dimensional virtual environment
 System importance

10. APPLICATION
 Critical servers.
 Nuclear and military facilitics.
 Airplanes and jet fighter.
 ATM, desktop computers and laptops.

11. SECURITY ANALYSIS
 3D Password Space Size.
 3D Password Distribution Knowledge.

12. ATTACKS AND COUNTER MEASURES
 Brute Force Attack
 Well-Studied Attack
 Shoulder Surfing Attack
 Timing Attack

13. ADVANTAGES OF 3D PASSWORD
 Several authentication schemes
 Easy to memorize
 Designed according to protected system
 Highly flexible
 Extremely strong
 Provides secrets
 3D environment can be changed
 Password can change easily
 Difficult to crack
 Freedom to select
 Difficult to share
 3D graphical password has no limit

14. DISADVANTAGES
 Difficult for blind people to use this technology.
 Requires sophisticated computer technology.
 Expensive.
 A lot of program coding is required.

15. CONCLUSION
 3D password is a multi factor authentication scheme that
combines the various authentication schemes into a single
3D virtual environment.
 Designing a simple and easy to use 3D virtual environment
is a factor that leads to a higher user acceptability of a 3D
password system.
