2. 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.

3. 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)

4. Common Authentication
Techniques used in computer
world
1. Textual Passwords(Recall Based)-:Recall
what you have created before.
2. Graphical Passwords:
(Recall Based+Recognition Based)
Biometric schemes
(fingerprints,voice recognition etc)

5. 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

6. 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.

7. 3D PASSWORD SCHEME
 The 3D Password scheme is a new
authentication scheme that combine
RECOGNITION
+ RECALL
+TOKENS
+BIOMETRIC
In one authentication system

8.  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

9. 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

10. 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.

11. 3D Password Application Areas
 Critical Servers
 Nuclear and military Facilities
 Airplanes and JetFighters
 ATMs,Desktop and Laptop Logins, Web
Authentication
