3.  Passwords are used for
 Authentication
 Authorization
 Access Control
o There are two types of passwords
 Text based
 Graphical based

4.  A graphical password is an authentication system that works by
having the user select from images, in a specific order, presented
in a graphical user interface (GUI). For this reason, the graphical-
password approach is sometimes called graphical user
authentication (GUA).
 A graphical password is easier than a text-based password for
most people to remember.
 Graphical passwords may offer better security than text-based
passwords because many people, in an attempt to memorize text-
based passwords, use plain words .

5.  We have integrated sound signature to help in recalling the
password.
 The proposed system creates user profile as follows-
Master vector - (User ID, Sound Signature frequency, Tolerance)
Detailed Vector - (Image, Click Points)
As an example of vectors -
Master vector (Smith , 2689, 50)
Detailed Vector

6.  Enters User ID and select one sound frequency which he want to be played
at login time, a tolerance value is also selected with will decide that the
user is legitimate or an imposter. To create detailed vector user has to
select sequence of images and clicks on each image at click points of his
choice. Profile vector is created.

7.  Registration
 Reset password
 Login application
 Profile matching
System

8.  In registration process user need to register to the system .
 New user gets registered with his details and his password is
generated according to the values at the x and y axis of the
particular point.
User Details
Register
get unique
login id by
sms

9.  In this module user can reset his/her password by login into the
system.
User Login
Reset
Password

10.  User can login through his/her username &
password.
Login Details
login

11.  In this module the system validates and verifies checks the profile
of user and sends SMS to the user mobile.

after login

12. Advantages Dis-advanages
 Provide a way of more human friendly
passwords while increasing the security
level.
 On average-millions of years to break
into systems.
 Dictionary attacks are infeasible.
 Password registration and log-in
process take too long.
 Require much more storage space than
text based passwords.
 Shoulder Surfing-
 As the name implies, shoulder
surfing is watching over people's
shoulders as they process information.
 Because of their graphic nature,
nearly all graphical password
schemes are quite vulnerable to
shoulder surfing.

13.  Picture passwords are an alternative to textual
alphanumeric password.
 By the solution of the integration of sound
signature ,it becomes more secure & easier
password scheme.
