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

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

5. BIOMETRIC BASED
Fingerprint ,palm prints ,hand geometry ,face
recognition
Intrusiveness upon a user’s personal characteristics.
GRAPHICAL PASSWORDS
Recognition based
Recall based

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

9. SECURITY ANALYSIS
3D Password Space Size.
3D Password Distribution Knowledge.

10. 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
