The document discusses 3-D password technology for more secure authentication. It describes existing authentication systems like textual passwords, graphical passwords, biometrics, and token-based systems. A 3-D password presents a virtual environment where the user interacts with virtual objects in a certain sequence and combination to authenticate. The virtual environment and objects can mimic real-life scenarios. 3-D passwords offer flexibility, strength, and ease of memorization while respecting privacy. Their main applications are for critical systems like servers, military facilities, and banks. The document also covers potential attacks and countermeasures for 3-D passwords.

1. 3-D Password
Technology
for more secure
authentication

2.  TEXTUAL PASSWORD
 GRAPHICAL PASSWORD
 BIOMETRICS
 TOKEN BASED
Existing
System

3. • The 3 d password which are more
customizable and very interesting way of
authentication.
• A 3-d password is a multifactor authentication
scheme that combine
Recognition
+ recall
+ token
+biometrics
in one authentication system

4. • The 3D password presents a virtual
environment containing various virtual
objects.
• The user walks through the environment and
interacts with the objects.
• It is the combination and sequence of user
interactions that occurs in 3D environment.

5. 3-D virtual environment

7. Virtual objects
• Virtual objects can be any object we encounter in real life.
 A computer on which the user can type in.
 A fingerprint reader that requires users finferprint.
 A paper or white board on which users can type
 An automated teller machine (ATM) machine that requires a
tokem.
 A light that can be switched on/off.
 A television or radio.
 A car that can be driven.
 A graphical password scheme.

8. 3Dvirtual environment
• 3-D virtual environment affects the usability, effectiveness, and
acceptability of a 3-D password system.
• 3-D environment reflects one administration needs and the security
requirements.

9. The design of 3D virtual environments
should follow these guidelines:
 Real life similarity
 Object uniqueness & distinction
 3-D virtual environment size
 Number of objects & their types.

10. advantages
 Flexibility
 Strength
 Ease to memorize
 Respect of privacy

11. APPLICATIONS
The 3D password’s main application domains are protecting
critical systems and resources.
 Critical Servers
 Nuclear reactors & military facilities
 Airplanes and missile guiding
 Banks

12. A small virtual environment can be used in the following
systems like -
• Atm
• Personal digital assistance
• Desktop computers & laptops
• Web authentication etc.

13. ATTACKSANDCOUNTERMEASURES
 Brute force attack
 Well studied attack
 Shoulder-surfing attack

14. CONCLUSION
• The authentication can be improved with 3d password ,
because the unauthorized person may not interact with
same object at a particular location as the legitimate user.
• It is difficult to crack , because it has no fixed number of
steps and a particular procedure.
• Added with biometrics and token verification this schema
becomes almost unbreakable.
