Introduction

Current authentication systems suffer from many weaknesses. Textual passwords are commonly used, users do not follow their requirements. Users tend to choose meaningful words from dictionaries, which make textual passwords easy to break. In this presentation ,we present and evaluate our contribution, i.e., the 3-D password.

Authentication

Authentication is a process of validating who are you to whom you claimed to be

Human authentication techniques are as follows:

1. Knowledge Base (What you know)

2. Token Based(what you have)

3. Biometrics(what you are)

4. Recognition Based(What you recognize)

Common Authentication Techniques used in computer world1. Textual Passwords(Recall Based)-:Recall

what you have created before.

2. Graphical Passwords:

(Recall Based+Recognition Based)

Biometric schemes

(fingerprints,voice recognition etc)

Drawbacks

Textual Password:◦ Textual Passwords should be easy to

remember at the same time hard to guess

◦ Full password space for 8 characters consisting of both numbers and characters is 2 X 10¹⁴

◦ From an research 25% of the passwords out of 15,000 users can guessed correctly by using brute force dictionary

Drawbacks

Graphical Password◦ Graphical passwords can be easily

recorded as these schemes take a long time.

◦ They require special scanning device to authenticate the user which is not acceptable for remote and internet users.

3D PASSWORD SCHEME

The 3D Password scheme is a new authentication scheme that combine

RECOGNITION

+ RECALL

+TOKENS

+BIOMETRIC

In one authentication system

The 3D password presents a virtual environment containing various virtual objects.

The user walks through the environment and interacts with the objects

The 3d Password is simply the combination and sequence of user interactions that occur in the 3D environment

3D Password selection

Virtual objects can be any object we encounter in real life:

A computer on which the user can type

A fingerprint reader that requires users fingerprint

A paper or white board on which user can type

A 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

3D Passwords Differentiators

Flexibility:3D Passwords allows Multifactor authentication biometric , textual passwords can be embedded in 3D password technology.

Strength: This scenario provides almost unlimited passwords possibility.

Ease to Memorize: can be remembered in the form of short story.

Respect of Privacy: Organizers can select authentication schemes that respect users privacy.

3D Password Application Areas

Critical Servers

Nuclear and military Facilities

Airplanes and JetFighters

ATMs,Desktop and Laptop Logins, Web Authentication
