3D passwords provide a more secure authentication method that combines recognition, recall, tokens, and biometrics. A 3D password involves a user authenticating in a virtual 3D environment by interacting with virtual objects like typing on a keyboard or using an ATM. This authentication method is more difficult to crack than traditional passwords since there is no fixed procedure and unauthorized individuals would have trouble replicating the exact interactions. When combined with biometric or token verification, 3D passwords become nearly unbreakable.

2. INTRODUCTION
 Current authentification suffer
from many weeknesss .Textual
passwords are commonly used,users
donot follow their requirements.
Users tends to choose meaningfull
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
out contribution this is the 3D
PASSWORD.

3. Existing Systems
 Textual Pssword
 Graphical Password
 Biometric
 Token based

4. PASSWORD
How secure is our password ?
Now with the technology change ,fast processors
and many ools on the internet, cracking passwords
has become the children play.
Ten years back Klein performed such tests and he
could crack 10-15 passwords per day

5. Drawbacks

6. The 3D password which are more
customizable,and very interesting way of
authentification.
A 3D password is a multifactor
authentification scheme that combine.
RECOGNITION
+RECALL
+TOKENS
+BIOMETRICS
in one authentification system.

7. Virtual objects
virtual objects can be any objects we encounter in real life.
A computer on which the user can type in
A fingerprint reader that requires users fingerprint
A paper or white board on which user can type
An Automated teller(ATM) machine that requires a token
A light that can be switched on/off
A television or radio
A car that can be driven
A graphical password scheme

8. 3-D Virtual Environment
3D Virtual Environment
3-D Virtual environment affects the usability,effectiveness,and
acceptability of a 3-D password System.
3-D environment reflects the administration needs and the security requirement

9. The Design of 3D Virtual environments
should follow these guidelines.
Real Life Similarty
Object Uniqueness & Distinction
3D Virtual Environment size
Number of objects & their types
System Importance

10. Advantages
Flexibility
Strength
Ease to Memorize
Respect of privacy

11. Application
The 3D password’s main application domains are protecting critical Systems and
resources.
Critical servers
Nuclear Reactors & military Facilities
Airplanes and missile Guiding

12. A small Virtual environment can be used in the following
Systems like-
Atm
Personal digital assistance
Desktop computers & laptops
Web authentication etc.

13. Attacks and Countermeasures
Brute force attack
Well studied attack
Shoulder surfing attack

14. CONCLUSION
 The authentification can be improved with 3D password,because the
unautherised person may not interact with same object at a particular
location as the legitimate user.
 It is difficult to crack,because it has no fixed number of steps and a particular
procedure.
 Added with biometrics or token verification this schema become almost
unbreakable.
