Authentication
Authentication is a process of validating who are you to whom you claimed to be
Human authentication techniques are as follows:
Knowledge Base (What you know)
Token Based(what you have)
Biometrics(what you are)
Recognition Based(What you recognise)
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
Graphical Password
Graphical passwords can be easily recorded as these schemes take a long time.
One main drawback of applying biometric is its intrusiveness upon a users personnel characteristics.
They require special scanning device to authenticate the user which is not acceptable for remote and internet users.
3D PASSWORD SCHEME
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
