Introduction
• The authentication has become a serious
field of research with misuse of
technology.
• 3D passwords are customizable and
interesting way of authentication.
• It presents a 3D virtual environment with
virtual objects.
• Virtual objects can be any object that we
encounter in real life.

Authentication Scheme
1. Token Based Authentication : ATM
Cards, Keys , ID Cards
2. Biometric Based Authentication :
fingerprints, palm prints, hand geometry,
face recognition, voice recognition, iris
recognition, and retina recognition
3. Recall Based Authentication-:Recall
what you have created before.
4. Graphical Passwords: (Recall Based +
Recognition Based).

Conclusion
• 3D password is a multi factor authentication scheme that
combines the various authentication schemes into a single 3D
virtual environment.
• Design of the 3D virtual environment is the selection of
objects inside the environment and the object's type reflect the
resulted password space
• Password space is very large compared to any existing
authentication schemes
