The document proposes a 3D password authentication system that combines recognition, recall, tokens, and biometrics by having users navigate a virtual 3D environment and interact with virtual objects in a specific sequence. This addresses weaknesses in traditional text passwords that are vulnerable to dictionary attacks. The 3D password would be more secure and customizable than existing authentication methods.

2. 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

3. Existing System
Textual password
Graphical Password
Biometrics
Token Based

4. •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.

7. •The 3D passwords3D passwords which are more customizable,
and very interesting way of authentication.
•A 3D password is a multifactor
authentication scheme that

in one authentication system.

8. The 3D password presents a virtual environmentvirtual 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.

9. 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 user’s 3d
password.

10. 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 user’s 3D password

11. 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

ENVIRONMENT

14. 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

15. 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

16. Advantages
 Flexibility
 Strength
 Ease to Memorize
 Respect of Privacy

17. Applications
The 3D password’s main application domains are protecting
critical systems and resources.
 Critical Servers
 Nuclear Reactors & military Facilities
 Airplanes and missile Guiding

18. A small virtual environment can be used in the following
systems like-
Atm
Personal digital assistance
Desktop computers & laptops
Web authentication etc.

20. Attacks and Countermeasures
Brute Force Attack
Well studied Attack
 Shoulder-surfing Attack

21. •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.
