HISTORY Years back Klein performed many tests on password
and he could crack 10-15 password per day. Nowwith the technology change fast processor and many
tools on the internet this has become a child play.Then comes the graphical password schema of
Blonder is considered to be recall based since theuser must remember location.
Further evolution for authentication withupcoming technology Jermyn et all had come upwith drawings, making the password morecomplicated.

Recently used technology is biometrics which
comprises of human reorganization like iris, DNAetc.
Now the latest and the most complex way toauthenticate the user is 3D Password.

WHAT IS BIOMETRICS?
Automate the identification or verification of individualbased on human characteristics or body organs.
Physiological : face, fingerprint, iris.
Behavioral : Hand written signature, voice

The 3D passwordswhich are more customizable,and very interesting way of authentication.
A 3D password is a multifactorauthentication scheme that
combine
RECOGNITION
+RECALL
+TOKENS
+BIOMETRICS
in one authentication system.

The 3D password presents a vir tual 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 occur in the 3D environment.

This is achieved through interacting only with the objects that
acquire information that the user is comfortable in providing.
It becomes much more difficult for the attacker to guess the users
3-D password.

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 thisschema becomes almost unbreakable.
