This research is based on the
human need regarding with their privacy and usefulness. Privacy deals with
preventing user information from anti- social activity and usefulness in terms
of the human power of remembrance. By putting such concept this paper proposes
a new algorithm called as P3-HA (Pictorial PanOut Password -Hunch Attack) which
is an advance version of previous pictorial techniques. The proposed system
instead of dextral based passwords uses pictorial based password. P3-HA limits
total number of click event generated in an image during selecting the
password. It not only restrict failed attempt on dextral during login but also
it restricts the number of trial attempts after the image challenge is give. This
image was given to the user at the time of registration. So, only authorized
user knows about the sequence used in an image. The image is divided into 16
grid cell and users have to click on 5 cells to generate his secret. Hence our
proposed system is very much preventive and secure as compared to other image
based techniques. Again at the time of challenge attacker will get scrambled
image and he has to identify the correct sequence to get access. The number of
click points is restricted with 3 attempts only after that the user gets
blocked.
