This document proposes a new authentication scheme called 3D passwords. It summarizes some limitations of existing authentication techniques like textual passwords and graphical passwords. 3D passwords aim to overcome these limitations by combining recognition, recall, tokens, and biometrics into a 3D virtual environment where a user's interactions with objects constitute their unique password. The proposed 3D password scheme provides advantages like flexibility, strength, and ease of memorization compared to other authentication methods.

Presented by

2. Authentication is an important factor of
security.
There are many authentication are
available such as graphical passwords,
Biometric identification, etc.,
But each of these had some drawbacks.
To overcome the limitations of the
existing authentication techniques, a new
improved authentication scheme is
introduced, i.e. 3D password.
Abstract

3. Commonly used authentication schemes
are textual passwords, graphical
passwords and biometrics.
3D password is a multifactor
authentication scheme.
To be authenticated, we require a 3D
virtual environment.

Authentication scheme

6. Multifactor Authentication

8. Combine all existing authentication
systems.
Contains several objects or item with
which the user can interact.
It reflects the users performances and
requirements.
Description

9. Recall based techniques require the user
to repeat our reproduce the secret that
the user created before.
Textual Passwords should be easy to
remember at the same time hard to guess.
One major drawback of textual password
is that Full password space for 8
characters consisting of both numbers
and characters is 2 *1024.
From research 25% of the passwords out
of 15,000 users can guessed correctly by
using brute force dictionary.
Textual Passwords

10. Graphical password are based on the
idea that a users can recall and recognize
pictures more than words.
But most graphical passwords are
susceptible for shoulder surfing attacks,
where an attacker can observe or record
the valid user’s graphical password by
camera.
 Currently most of the graphical
password are in the research phase and
require more enhancement and usability
studies to develop them in the market.
Graphical Passwords

11. The 3D Password scheme is a new
authentication scheme that combines
RECOGNITION + RECALL + TOKENS +
BIOMETRIC in one authentication system.
The system of authentication presents a 3D
virtual environment to the user where in the
user navigates and interacts with the multitude
of objects that may be present.
The order in which actions and interactions
are performed with respect to the objects
constitutes the user’s 3D password.
3D Passwords

12. Flexibility
Strength
Ease to memorize
Respect of privacy
Advantages

13. Time and memory requirements
Cost of implementations and
maintenance
Disadvantages

14. Critical servers.
Nuclear and military facilities.
Airplanes and jetfighters.
ATMs, PDAs, Desktop computers and
laptops.
Aerospace, etc.,
Applications

15. 3D password scheme is a very strong
authentication scheme.
It is very difficult to crack the password
which is created using such a strong
authentication scheme.
This paper proposes the mechanism to
make existing 3D password system
stronger against such kind of attacks.
Conclusion

16. This paper proposes the solution to make
the existing 3D password authentication
system stronger.
 But at the same time it is making the
system more complicated.
Handling lots of image processing and
speech recognition task is the area of
research in future.
Future Enhancement
