ABSTRACTABSTRACT

• Current systems suffers from many weakness

Textual : easy to hack

Tokens : theft

Graphical : less password space

Biometric systems : users resist

• 3D password system overcomes all the above

weakness.

3D PASSWORD : WHAT IS IT ?

It is a multifactor authentication scheme, where user

navigates and interacts with various objects.

INTRODUCTIONINTRODUCTION

AuthenticationAuthentication::

It is the act of establishing or confirming something as

authentic, that is, that claims made by or about the subject are

true.

INTRODUCTIONINTRODUCTION

Knowledge based (what you know)

Token based (what you have)

Biometrics (what you are )

3D-PASSWORD 3D-PASSWORD

Types of authentication:

(contd..)(contd..)

Authentication Methods:

The are two types of techniques for doing this. First is comparing the attributes of the object itself to know its origin. Second type relies on documentation or other external affirmations.

3D PASSWORD SCHEME3D PASSWORD SCHEME

REQUIREMENTS:

• Should be combination of recall based, recognition based

etc.

• Freedom to select combination of the above schemes.

• Easy to remember & change.

• Difficult to share.

SELECTION AND INPUTSSELECTION AND INPUTS::

• Space of size G*G*G, (x,y,z) all in [1,....,G].

• For example, consider a user who navigates through the 3D virtual environment that consists of an office and a meeting room.

3D-PASSWORD 3D-PASSWORD

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 “FALCON.” 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.

· (10, 24, 91) Action = Open the office door;

· (10, 24, 91) Action = Close the office door;

· (4, 34, 18) Action = Typing, “F”;

· (4, 34, 18) Action = Typing, “A”;

· (4, 34, 18) Action = Typing, “L”;

· (4, 34, 18) Action = Typing, “C”;

· (4, 34, 18) Action = Typing, “O”;

· (4, 34, 18) Action = Typing, “N”;

· (10, 24, 80) Action = Pick up the pen;

· (1, 18, 80) Action = Drawing, point = (330, 130).

• Nuclear and military services

• Airplanes and jet fighters

• ATM

• Internet

ADVANTAGES

Easiness to memorize

 Flexibility

Strength

Secrets those are not easy to write down on paper. Provide secrets that can be easily revoked or changed.

The scheme secrets should be difficult to share with others.

ATTACKS AND COUNTER MEASURES 

Brute Force Attack

Well Studied Attack

Shoulder Surfing Attack

Timing Attack

CONCLUSION CONCLUSION

• Combines various authentication schemes.

• Uses existing scheme or upcoming scheme.

• Environment – easy and secure.

• User's preference and requirements are valued.

• The design of the 3D virtual environment, the

selection of objects inside the environment and the

object’s type reflect the resulted password space.
