INTRODUCTION
Current Authentification 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

PASSWORD
           How secure is your password?

             Now with the technology change,
             fast processors and many tools on
             the Internet, cracking password has
             become a Child's Play.
             Ten years back Klein performed
             such tests and he could crack 10-15
             passwords per day.

3D PASSWORD
The 3D passwords which are more customizable,
and very interesting way of authentication.

A 3D password is a multifactor
authentication scheme that
combine

 RECOGNITION
    +RECALL
      +TOKENS
         +BIOMETRICS

 in one authentication system.
The 3D password presents a virtual environment
 containing various virtual objects.

 The user walks through the environment and
 interacts with the objects.

It is the combination and sequence of user
 interactions that occur in the 3D environment.
Brief Description of System
The user is presented with this 3d virtual environment where
  the user navigates and interacts with various objects.




The sequence of actions and interactions towards the
  objects inside the 3d environment constructs the users 3d
  password.
System Implementation
For example, the user can enter the virtual environment
  and type something on a computer that exists in (x1 , y1 ,
  z1 ) position, then enter a room that has a fingerprint
  recognition device that exists in a position (x2 , y2 , z2 )
  and provide his/her fingerprint. Then, the user can go to
  the virtual garage, open the car door, and turn on the radio
  to a specific channel. The combination and the sequence
  of the previous actions toward the specific objects
  construct the users 3D password
Virtual objects
Virtual objects can be any object 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

3D 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
requirements.




                       3D Virtual Environment
The design of 3D virtual
environments should follow
these guidelines:

Real Life Similarity
Object Uniqueness & Distinction
3D Virtual Environment Size
Number of objects & their types
System Importance
Advantages
              Flexibility
              Strength
              Ease to Memorize
              Respect of Privacy
Applications

 The 3D passwords main application domains are protecting
 critical systems and resources.

 Critical Servers
 Nuclear Reactors & military Facilities
 Airplanes and missile Guiding
A small virtual environment can be used in the following
 systems like-

Atm


Personal digital assistance


Desktop computers & laptops


Web authentication etc.
State Diagram
Attacks and Countermeasures

Brute Force Attack


Well studied Attack


 Shoulder-surfing Attack
Conclusion
 The authentication can be improved with 3d
 password ,because the unauthorized 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 and token verification this
 schema becomes almost unbreakable.
