The document proposes a new authentication technique called 3D Password. 3D Password combines existing recall-based and recognition-based authentication schemes. It uses a virtual environment containing various virtual objects for users to interact with. The virtual environment provides multiple authentication options to users and makes brute force attacks more difficult. 3D Password offers increased security for systems over traditional authentication methods but also has some disadvantages like increased time, memory usage, and complexity.

2. Abstract
 Authentication of any system means providing a
security to that system.
 There are number of authentication techniques like
textual, biometrics etc. Each of these techniques has
some limitations and drawbacks.
 To overcome the drawbacks, a new authenticate
technique is now available, That is known as 3D
Password.
 The advantage of the 3D password is that combine
the authentication of existing system and providing
high security to user.

3. General Terms
• Security, authentication.
Keywords
• 3D Password, Virtual Environment.

4. Type of authentication techniques

5. 3D Password
 3D password is combination of recall based
scheme and recognition based scheme.
 3D password is multifactor password & multi-
password authentication scheme.
 3D password provides a virtual environment for
containing various virtual objects. Through this
virtual environment, the user interacts with virtual
object.

6. Virtual environment
 A virtual environment is a computer-based
simulated environment.
 The 3D virtual environment consists of many
items and objects.
 Each item has different responses to action.

9. Advantage of 3D password
It provides user options to choose the type
of authentication of his/her own choice.
It eliminates a brute force attack.
Provides high level security to the system.
Secure against a software like key logger.

10. Disadvantage of 3D password
Shoulder attack.
More time and memory.
It’s expensive.
Complexity.

11. Applications for 3D Password
1. Critical servers.
2. Nuclear reactions and military facilities.
3. Airplane, jet fighters and missile guiding.
4. A small virtual environment can be used in
following areas:-
ATM, Desktop computers and laptop logins,
Security analysis, Web authentication.

12. Conclusion
3D Password mechanism is more secure and
reliable compare to other authentication
mechanism. By using 3D password we can
make any system more secure and it will be
beneficial for applications used in cooperate
world, govt. sector and in personal use.
