ABSTRACT
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. The human memory, in our scheme has to
undergo the facts of Recognition, Recalling, Biometrics or Token
based authentication. Once implemented and you log in to a
secure site, the 3D password GUI opens up. This is an additional
textual password which the user can simply put. Once he goes
through the first authentication, a 3D virtual room will open on
the screen
INTRODUCTION
Normally the authentication scheme the user undegoes is
paticularly very lenient or very strict.Throughout the yeras
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 someones
password.Therefore many algorithms have come up each with
an interesting approach toward calculation of a secret key.The
algorithms are such based to pick a random number in the range
of 10^6 and therefore the possbilities of the sane number coming
is rare.
2. 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. Many biometric
authentications have been proposed. However, users tend to
resist using biometrics because of their intrusiveness and the
effect on their privacy. Moreover, biometrics cannot be revoked.
The 3Dpassword is a multi factor authentication scheme. The
design of the 3D virtual environment and the type of objects
selected determine the 3D password key space. User have
freedom to select whether the 3D password will be solely recall,
recognition, or token based, or combination of two schemes or
more.
3. PROPOSED SYSTEM
The proposed system is a multi factor authentication scheme that
combines the benefits of various authentication schemes. Users
have the freedom to select whether the 3D password will be
solely recall, biometrics, recognition, or token based, or a
combination of two schemes or more. This freedom of selection
is necessary because users are different and they have different
requirements. Therefore, to ensure high user acceptability, the
user’s freedom of selection is important.
4. 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. The 3D
password can combine most existing authentication schemes
such as textual passwords, graphical passwords, and various
types of biometrics into a 3D virtual environment. The choice of
what authentication schemes will be part of the user's 3D
password reflects the user's preferences and requirements. A
user who prefers to remember and recall a password might
choose textual and graphical password as part of their 3D
password. On the other hand users who have more difficulty
with memory or recall might prefer to choose smart cards or
biometrics as part of their 3D password. Moreover user who
prefers to keep any kind of biometric data private might not
interact with object that requires biometric information.
Therefore it is the user's choice and decision to construct the
desired and preferred 3D password.
5. SYSTEM IMPLIMENTATION
The 3D password is a multi factor authentication scheme. The
3D password presents a 3D virtual environment containing
various virtual objects. The user navigates through this
environment and interacts with the objects. The 3D password is
simply the combination and the sequence of user interactions
that occur in the 3D virtual environment. The 3D password can
combine recognition, recall, token, and biometrics based
systems into one authentication scheme. This can be done by
designing a 3D virtual environment that contains objects that
request information to be recalled, information to be recognized,
tokens to be presented, and biometric data to be verified.
0. ADVANTAGES
1. Provides security.
2. This 3D password can’t take by any other person.
3. 3D graphical password has no limit.
4. Password can change easily.
5. Implementation of the system is easy.
6. Password can remember easily.
7. This password helps to keep lot of personal details.
11. DISADVANTAGES
1. Difficult for blind people to use this technology.
2. Requires sophisticated computer technology.
3. Expensive.
4. A lot of program coding is required.
12. FUTURE SCOPE
The 3-D password is a multifactor authentication scheme that
combines these various authentication schemes into a single 3-D
virtual environment. The virtual environment can contain any
existing authentication scheme or even any upcoming
authentication schemes by adding it as a response to actions
performed on an object. Therefore, the resulted password space
becomes very large compared to any existing authentication
schemes.
The design of the 3-D virtual environment, the selections of
objects inside the environment, and the object’s type reflect the
resulted password space. It is the task of the system
administrator to design the environment and to select the International Conference on Advances in Communication and Computing Technologies (ICACACT) 2012

appropriate object that reflects the protected system
requirements. Additionally, designing a simple and easy to use
3-D virtual environment is a factor that leads to a higher user
acceptability of a 3-D password system.
The choice of what authentication schemes will be part of the
user’s 3-D password reflects the user’s preferences and
requirements. A user who prefers to remember and recall a
password might choose textual and graphical passwords as part
of their 3-D password. On the other hand, users who have more
difficulty with memory or recall might prefer to choose smart
cards or biometrics as part of their 3-D password. Moreover,
users who prefer to keep any kind of biometrical data private
might not interact with objects that require biometric
information. Therefore, it is the user’s choice and decision to
construct the desired and preferred 3-D password.
The 3-D password is still in its early stages. Designing various
kinds of 3-D virtual environments, deciding on pass-word
spaces, and interpreting user feedback and experiences from
such environments will result in enhancing and improving the
user experience of the 3-D password. Moreover, gathering
attackers from different backgrounds to break the system is one
of the future works that will lead to system improvement and
prove the complexity of breaking a 3-D password. Moreover, it
will demonstrate how the attackers will acquire the knowledge
of the most probable 3-D passwords to launch their attacks.
Shoulder surfing attacks are still possible and effective against
3-D passwords. Therefore, a proper solution is a field of
research
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. The
design of the 3D virtual environment the selection of objects
inside the environment and the object's type reflect the resulted
password space. It is the task of the system administrator to
design the environment and to select the appropriate object that
reflects the protected system requirements. Designing a simple
and easy to use 3D virtual environment is a factor that leads to a
higher user acceptability of a 3D password system. The choice
of what authentication scheme will be part of user's 3D
password reflects the user's preferences and requirements.
