ABSTRACT
Common authentication techniques used in computer are textual passwords and graphical passwords
The main drawbacks of using textual passwords are they should be easy to remember at the same time hard to guess. From a research 25% of the passwords out of 15,000 users can be guessed correctly by brute force dictionary
The main drawback of graphical passwords is they require special scanning device to authenticate the user which is not acceptable for remote and internet users
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.
Virtual objects can be any object we encounter in real life like a computer on which the user can type, a television or a radio, a paper or a white board on which user can type
For example let us assume the user enters a virtual office then performs the following action:
1. (10,24,91) Action=open the office door
2. (10,24,91) Action=close office door
3. (4,34,18) Action=typing, ”c”
4. (4,34,18) Action=typing, ”o”
5. (4,34,18) Action=typing, “n”
6. (10,24,80) Action=pick up the pen
7. (1,18,80)=draw point=(330,130)
3D passwords allow multifactor authentication biometric, textual passwords can be embedded in 3D password technology. They can be easily remembered in the form of short story
The 3D password applications are critical servers, nuclear and military facilities, ATMs, desktop and laptop logins, web authentication etc..
Attacks like brute force attack and well studied attack on 3D passwords are very difficult because 3D passwords are more secured.
