3D PASSWORD Prepared By Gauswami Hetal G.R.NO.707
Topic of overview • Introduction • Authentication schemes • Functionalities required • 3D password selection and input • Virtual environment design guidelines • Applications • Security analysis • Advantages & disadvantages
Introduction • Commonly used authentication schemes are textual passwords, graphical passwords and biometrics. • 3D password is a multifactor authentication scheme. • To be authenticated, we require 3D virtual environment. • combines recognition, recall, token and biometrics based systems. • Users choice to select the type of authentication technique.
Authentication Schemes
Knowledge based Password • Password is basically an encryption algorithms. • It is 8-15 character or slightly more than that. • Mostly textual passwords now a days are kept which are very simple.
Functionalities Required • New scheme should combine the existing authentication schemes. • Freedom to select the type of authentication techniques. • Should provide secrets that are easy to remember, difficult to guess.
3D Password Selection & Input • 3D environment space represented by the co-ordinates. • User navigate into the 3D virtual environment using any input device. • The sequence of actions and interaction forms the user 3D password.
3D Virtual Environment • 3D virtual environment affects the usability, effectiveness & acceptability of a 3D password system. • 3D environment reflects the administration needs the security requirements.
Application • Critical servers. • Nuclear & military facilities. • Airplanes & jet fighters. • ATM, desktop computers & laptops.
Disadvantages • Difficult for blind people to use this technology. • Requires sophisticated computers technology expensive. • A lot of program coding is required.

3D passwords-Advanced Authentication Systems
The increase in the usage of computer systems has given rise to many security concerns. One of the major security concern is authentication , which is the process of validating who you are to whom you claimed to be.
Current authentication systems suffer from various weaknesses. People usually use textual passwords; however they do not follow their requirements.The issue is that users intend to use meaningful words from the dictionary, which eventually are easier to break and vulnerable to attack.
A major drawback of the textual password is its conflicting requirements- the selection of a password that is easy to remember(for the user), and at the same time, hard to guess(to prevent unauthorized access to private data).
As a solution, many biometric authentications have been proposed. These include:
However, users usually tend to resist biometrics because:
- because of their effect on privacy and their intrusiveness.
- moreover, biometrics cannot be revoked.
3D password is a multi factor authentication scheme, that is, it is a security approach that requires the user to provide more than 1 identity factor before accessing their data.
Some factors include:
- what a user KNOWS: that is their password.
- what a user HAS: that is a smart card/hard token.
- what a user IS: that is a retinal scan/ finger print.
To be authenticated into a secure system, we present a 3-D virtual environment where the user navigates and interacts with various objects. The sequence of actions and interactions towards the objects inside the environment.Then the user’s password is constructed. The password can combine most existing authentication schemes, i.e., graphical and textual passwords and various biometrics into a virtual 3D environment.
The design of the 3D virtual environment and the type of objects selected determine the 3D password key space.
Advantages:
- easy to remember and is highly secure.
- easy to customise.
- difficult to share.
- 3D graphical password has no limit.
Disadvantages:
- difficult to use for the blind people.
- requires complex computer technology.
