2. WHY 3D PASSWORD ??
Current Authentication suffer from many weakness .Textual passwords
are commonly used, users do not follow their requirements .Users
tends to choose meaningful words from dictionaries, which makes
the textual passwords easy to break and vulnerable to dictionary or
brute force attacks.In this paper, we present and evaluate our
contribution i.e. the 3D password

3. INTRODUCTION:-
A 3D password is a multifactor authentication scheme that combine in one
authentication system
.
The 3D password presents a 3D virtual environment containing various
virtual objects.

9. More than one authorization

10. USE OF 3D PASSWORD
 Critical Servers
 Banking
 Nuclear and military Facilities
 Airplanes and JetFighters

11. ADVANTAGES OF 3D PASSWORD
 Provides security.
 3D graphical password has no limit.
 Password can change easily.
 Password can be remember easily.

12. DISADVANTAGES OF 3D PASSWORD
Difficult for blind people to use this technology.
Expensive scheme.
A lot of program coding is required.

13. Attacks & countermeasures :
Well-studied attacks
Brute force Attacks
Timing Attacks
Shoulder Surfing attacks

14. Conclusion:
It is difficult to crack ,because it has no fixed number of steps and a
particular procedure.
Added with biometrics and token verification this schema
becomes almost unbreakable.
