3D-PASSWORD

ABSTRACT •

•

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

INTRODUCTION 3D PASSWORD : WHAT IS IT ?

It is a multifactor authentication scheme, where user navigates and interacts with various objects. Authentication:

It is the act of establishing or confirming something as authentic, that is, that claims made by or about the subject are true.

3D-PASSWORD

INTRODUCTION Types of authentication:  Knowledge  Token

based (what you know)

based (what you have)

 Biometrics

(what you are )

Authentication Methods:

The are two types of techniques for doing this.  First is comparing the attributes of the object itself to know its srcin.

 Second type relies on documentation or other external affirmations.

3D-PASSWORD

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.

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 “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, 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).

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.
