Abstract
The melodramatic increase of computer
usage has given rise to many security
concerns. One major security concern is
Authentication; process of validating who
you are to who you claimed to be.
Authentication provides more security to
the system. Many existing authentication
schemes such as textual password,
graphical password etc. are available, each
one having its own drawbacks and
limitations. This paper introduced a new
authentication technique, called 3D
Password that overcomes the drawback of
previously existing authentication
schemes. The 3D Password is multi-factor
and multipassword authentication
techniques that consist of 3D virtual
environment containing real time object
scenarios. 3D virtual environment is the
user interface that looks like same as real
time environment but is not actual real
time environment. Compared to other
authentication techniques 3D Password is
more advanced and secure, as it is easy to
use and difficult to break. This paper also
focuses on explaining what is 3D
Password?, how to create 3D password,
working of 3D Password and some design
principles for designing 3D virtual
environment.
1. 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 some ones
password. Therefore many algorithms

2 | P a g e
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 possibilities 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

3 | P a g e
of selection is important.

Authentication Scheme
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 mor e 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 thatrequires
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,

4 | P a g e
information to be recognized, tokens to
be presented, and biometric data to be
verified. Virtual objects can be any
object that we encounter in real life.
Any obvious actions and interactions
toward the real life objects can be done
in the virtual 3D environment toward
the virtual objects. Moreover, any user
input (such as speaking in a specific
location) in the virtual 3D environment
can be considered as a part of the 3D
password. We can have the following
objects:
1) A computer with which the user can
type;
2) A fingerprint reader that requires the
user’s fingerprint;
3) A biometric recognition device;
4) A paper or a white board that a user
can write, sign, or draw on;
5) An automated teller machine (ATM)
that requests a token;
;6) A light that can be switched on/off;
7) A television or radio where channels
can be selected
8) A staple that can be punched;
9) A car that can be driven;
10) A book that can be moved from
one place to another;
11) Any graphical password scheme;
12) Any real life object;
13) Any upcoming authentication
scheme.
The action toward an object (assume a
fingerprint recognition device) that
exists in location (x1, y1, z1) is
different from the actions toward a
similar object (another fingerprint
recognition device) that exists in
location (x2, y2, z2), where x1 = x2 ,
y1 = y2, and z1 = z2 . Therefore, to
perform the legitimate 3D password,
the user must follow the same scenario
performed by the legitimate user. This
means interacting with the same
objects that reside at the exact
locations and perform the exact actions
in the proper sequence.
6. 3D PASSWORD SELECTION AND
INPUT
Let us consider a 3D virtual
environment space of size G ×G × G.
The 3D environment space is
Represented by the coordinates (x, y,
z) [1, . . . , G] ×[1, . . . , G] ×[1, . . . ,
G]. The objects are distributed in the
3D virtual environment with unique (x,

5 | P a g e
y, z) coordinates. We assume that the
user can navigate into the 3D virtual
environment and interact with the
objects using any input device such as
a mouse, key board, fingerprint
scanner, iris scanner, stylus, card
reader, and microphone. We consider
the sequence of those actions
andinteractions using the previous input
devices as the user’s 3D password. For
example, consider a user who navigates
through the 3D virtual environment that
consists of an office and a meeting room.
Let us assume that the user is in the virtual
office and the user turns around to the
door located in (10, 24, 91) and opens it.
Then, the user closes the door. The user
then finds a computer to the left, which
exists in the position (4, 34, 18), and the
user types “JNTC.” Then, the user walks
to the meeting room and picks up a pen
located at (10, 24, 80) and draws only one
dot in a paper located in (1, 18, 30), which
is the dot (x, y) coordinate relative to the
paper space is (330, 130). The user then
presses the login button. The initial
representation of user actions in the
3Dvirtual environment can be recorded as
follows: (10, 24, 91) Action = Open the
office door; (10, 24, 91) Action = Close
the office door; (4, 34, 18) Action =
Typing, “J”; (4, 34, 18) Action = Typing,
“N”; (4, 34, 18) Action = Typing, “T”; (4,
34, 18) Action = Typing, “C”;

7. 3D PASSWORD CREATION
As 3D Password is multi-feature so
multiple password schemes such as textual
password, graphical password, Biometrics,
and even token based passwords together
can be used as a part of users 3D
Password. Different Users have different
requirements so users must be given the
freedom of selection and decision to
choose which Authentication schemes will
be part of users 3D Password. The figure
depicts state diagram for creating a 3D
Password application.

Fig4:STATE DIAGRAM OF A 3D
PASSWORD APPLICATION
The design of the 3 D virtual environments
affects the usability, effectiveness,
acceptability of 3D password. The first
step in building a 3D password system is
to design a 3D environment that reflects
the administration needs and the security
requirements. The design of 3D virtual
environments should follow these
guidelines.
8. DESIGN GUIDELINES Real Life
Similarity:
The prospective 3D virtual environment
should reflect what people are used to
seeing in real life. Objects used in virtual
environments should be relatively similar
in size to real objects (sized to scale).
Possible actions and interactions toward
virtual objects should reflect real life
situations. Object responses should be
realistic. The target should have a 3D
virtual environment that users can interact.
Object uniqueness and distinction: Every
virtual object or item in the 3D virtual
environment is different from any other
virtual object. The uniqueness comes from
the fact that every virtual object has its
own attributes such as position. Thus, the
prospective interaction with object 1 is not
equal to the interaction with object 2.
However, having similar objects such as
20 computers in one place might confuse
the user. Therefore, the design of the 3D
virtual environment should consider that
every object should be distinguishable
from other objects. Similarly, in designing
a 3D virtual environment, it should be
easy for users to navigate through and to
distinguish between objects. The
distinguishing factor increases the user’s
recognition of objects. Therefore, it
improves the system usability.
Three Dimensional Virtual Environment
Size: A 3D virtual environment can depict a
city or even the world. On the other hand, it
can depict a space as focused as a single room

7 | P a g e
or office. A large 3D virtual environment will
increase the time required by the user to
perform a 3D password. Moreover, a large 3D
virtual environment can contain a large
number of virtual objects. Therefore, the
probable 3D password space broadens.
However, a small 3D virtual environment
usually contains only a few objects, and thus,
performing a 3D password will take less time.
Number of objects and their types:
Part of designing a 3D virtual environment
is determining the types of objects and
how many objects should be placed in the
environment. The types of objects reflect
what kind of responses the object will
have. For simplicity, we can consider
requesting a textual password or a
fingerprint as an object response type.
Selecting the right object response types
and the number of objects affects the
probable password space of a 3D
password.
System Importance:
The 3D virtual environment should
consider what systems will be protected by
a 3D password The number of objects and
the types of objects that Have been used in
the 3D virtual environment should reflect
the importance of the protected system.
9. 3D PASSWORD APPLICATIONS
The 3D password can have a password
space that is very large compared to
other authentication schemes, so the
3D password’s main app lication
domains are p rotecting critical
systems and resources.
Critical server: Many large
organizations have critical servers that
are usually protected by a textual
password. A 3D password
uthentication proposes a sound
replacement for a textual password.
Nuclear and military facilities: such
facilities should be protected by the
most Powerful authentication systems.
The 3D password has a very large
probable password space, and since it
can contain token, biometrics,
recognition and knowledge based
Authentications in a single
authentication system, it is a sound
choice for high level security locations.
Airplanes and jet fighters: Because
of the possible threat of misusing
airplanes and jet fighters for religion,
political agendas, usage of such
airplanes should be protected by a
powerful authentication system. In
addition, 3D passwords can be used in
less critical systems because the 3D
virtual environment can be designed to
fit to any system needs. A small virtual
environment can be used in the
following systems like
1) ATM
2) Personal Digital Assistance

8 | P a g e
3) Desktop Computers & laptop logins
4) Web Authentication
5) Security Analysis
10. 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 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

9 | P a g e
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
13. 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.
