Introduction
Normally
the authentication scheme the user undergoes is particularly very lenient or
very strict. Throughout the years authentication has been a very interesting
approach. With all the means of technology developing, it can be very easy for
'others' to fabricate or to steal identity or to hack someone’s password.
Therefore many algorithms have come up each with an interesting approach toward
calculation of a secret key. Therefore we present our idea, the 3D passwords
which are more customizable and very interesting way of authentication. Now the
passwords are based on the fact of Human memory. Generally simple passwords are
set so as to quickly recall them.
Brief
Description Of System
The
proposed system is a multi factor authentication scheme. It can combine all
existing authentication schemes into a single 3D virtual environment .This 3D
virtual environment contains several objects or items with which the user can
interact. The user is presented with this 3D virtual environment where the user
navigates and interacts with various objects. The sequence of actions and
interactions toward the objects inside the 3D environment constructs the user’s
3D password.
Existing
System
Current
authentication systems suffer from many weaknesses. Textual passwords are
commonly used. Users tend to choose meaningful words from dictionaries, which
make textual passwords easy to break and vulnerable to dictionary or brute
force attacks. Many available graphical passwords have a password space that is
less than or equal to the textual password space. Smart cards or tokens can be
stolen.
Well-Studied
Attack
The attacker tries to find the highest
probable distribution of 3D passwords. In order to launch such an attack, the
attacker has to acquire knowledge of the most probable 3D password
distributions. This is very difficult because the attacker has to study all the
existing authentication schemes that are used in the 3D environment. It
requires a study of the user’s selection of objects for the 3D password.
Moreover, a well studied attack is very hard to accomplish since the attacker
has to perform a customized attack for every different 3D virtual environment
design.
Conclusion
The
3D password is a multi factor authentication scheme that combines the various
authentication schemes into a single 3D virtual environment. The virtual
environment can contain any existing authentication scheme or even any upcoming
authentication scheme or even any upcoming authentication schemes by adding it
as a response to actions performed on an object. Therefore the resulting
password space becomes very large compared to any existing authentication
schemes.
