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.

2. INTRODUCTION
 The 3-D password is a multifactor authentication scheme.
 It can combine all existing authentication schemes into a single 3-D virtual
environment.
 This 3-D virtual environment contains several objects or items with which the user
can interact.
 The type of interaction varies from one item to another.
 The 3-D password is constructed by observing the actions and interactions of the
user and by observing the sequences of such actions.

3D PASSWORD

5. BRIEF DESCRIPTION OF SYSTEM
 The 3D password presents a virtual environment containing various
virtual objects.
 The user walks through the environment and interacts with the objects.
 It is the combination and sequence of user interactions that occur in the
3D environment.

6. BRIEF DESCRIPTION OF SYSTEM
 The user is presented with this 3d virtual environment where the user navigates and
interacts with various objects.
 The sequence of actions and interactions towards the objects inside the 3d
environment constructs the user’s 3d password.

7. SYSTEM IMPLEMENTATION
 For example, the user can enter the virtual environment and type something on a
computer that exists in (x1 , y1 , z1 ) position
 then enter a room that has a fingerprint recognition device that exists in a position
(x2 , y2 , z2 ) and provide his/her fingerprint.
 Then, the user can go to the virtual garage, open the car door, and turn on the radio
to a specific channel.
 The combination and the sequence of the previous actions toward the specific
objects construct the user’s 3D password.

8. Virtual objects can be any object we encounter in real life:
 A computer on which the user can type in
 A fingerprint reader that requires users fingerprint
 A paper or white board on which user can type
 An Automated teller(ATM) machine that requires a token
 A light that can be switched on/off
 A television or radio
 A car that can be driven
 A graphical password scheme

acceptability of a 3-D password system.
• 3-D environment reflects the administration needs and the security
requirements.

11. ADVANTAGES
 Provides security.
 3D password can’t take by any other person.
 3D graphical password has no limit.
 Password can change easily.
 Implementation of the system is easy.
 Password can remember easily.
 Password helps to keep lot of personal
details.

12. APPLICATIONS
The 3D password’s main application domains are protecting critical systems and resources.
 Critical Servers
 Nuclear Reactors & military Facilities
 Airplanes and missile Guiding
 In addition, 3D passwords can be used in less critical systems
 A small virtual environment can be used in the following systems like
 ATM
 Personal Digital Assistance
 Desktop computers & laptops
 Web authentication etc.

14. ATTACKS AND COUNTERMEASURES
 To realize and understand how far an authentication scheme is secure, all possible
attack methods should be considered.
 Thorough study has to be done , whether the authentication scheme proposed is
immune against such attacks or not.
 Moreover, if the proposed authentication scheme is not immune, the countermeasures
have to be found that prevent such attacks.

15. ATTACKS AND COUNTERMEASURES
 Brute Force Attack:The attacker has to try all possible 3-D passwords.This kind of attack is very
difficult for the following reasons:
 Time required to login
 Cost of attacks
 Well-Studied Attack:The attacker tries to find the highest probable distribution of 3-D passwords.
However, to launch such an attack, the attacker has to acquire knowledge of the most probable 3-D
password distributions.
 Shoulder Surfing Attack:An attacker uses a camera to record the user’s 3-D password or tries to
watch the legitimate user while the 3-D password is being performed.This attack is the most
successful type of attack against 3-D passwords and some other graphical passwords.
 Timing Attack: In this attack, the attacker observes how long it takes the legitimate user to perform
a correct sign-in using the 3-D password.This observation gives the attacker an indication of the
legitimate user’s 3-D password length.

17. CONCLUSION
• The authentication can be improved with 3d password ,because the unauthorized person may not
interact with same object at a particular location as the legitimate user.
• It is difficult to crack ,because it has no fixed number of steps and a particular procedure.
• Added with biometrics and token verification this schema becomes almost unbreakable.
 The 3-D password is still in its early stages. Designing various kinds of 3-D virtual environments,
deciding on password spaces, and interpreting user feedback and experiences from such environments
will result in enhancing and improving the user experience of the 3-D password
