3. INTRODUCTION
Commonly used authentication schemes are textual passwords, graphical passwords and biometrics.
3D password is a multifactor authentication scheme.
To be authenticated, werequirea3Dvirtualenvironment.

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

5. AUTHENTICATION SCHEMES
KNOWLEDGE BASED
Recall based
Recognition based
TOKEN BASED
eg : smart card

6. BIOMETRIC BASED GRAPHICAL PASSWORDS
Fingerprint ,palm prints ,hand geometry ,face recognition
Intrusiveness upon a user’s personal characteristics.
GRAPHICAL PASSWORDS
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 toguess.

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 users3D password.

9. Representation of user actions in the 3D virtual environment
(10,24,91) Action=Open the office door;
(10,24,91) Action=Close the office door;
(4,34,18) Action= Typing,“F”;
(4,34,18) Action= Typing,”A”;
(4,34,18) Action= Typing,”L”;
(4,34,18) Action= Typing,”C”;
(4,34,18) Action= Typing,”O”;
(4,34,18) Action= Typing,”N”;
(10,24,80) Action= Pick up the pen;
(1,18,80) Action= Drawing, point=(330,130).

13. 3D VIRTUAL ENVIRONMENT DESIGN GUIDELINES
Real-life similarity
Object uniqueness and distinction
Three-dimensional virtual environment
System importance

14. APPLICATIONS Critical servers. Nuclear and military facilities.
Airplanes and jetfighters.
ATMs, PDA’s, desktop computers and laptops.

15. SECURITY ANALYSIS 3D Password Space Size.
3D Password Distribution Knowledge.

16. ATTACKS AND COUNTERMEASURES
Brute Force Attack
Well-Studied Attack
Shoulder Surfing Attack
Timing Attack

17. CONCLUSION
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
