Now, picture password to protect online account!

London: Find it difficult to remember your
password? Here`s some good news -- researchers claim to have
developed picture password for your online account, which will
also help protect against hacking.

An international team says that it`s actually a new kind
of login which relies on the fallibility of human memory to
prevent phishing attempts at stealing one`s account details,
the `New Scientist` reported.

The researchers at Stony Brook University in New York
have, in fact, come up with a system, called PhorceField,
that makes it almost impossible to login without viewing the
correct images.

PhorceField asks users to create a graphical password
by choosing four images in a particular order from a set of
twelve -- you might choose pictures of a loaf of bread, a
candle flame, and two more, for example.

These images are stored in a secret file on computer
that only the legitimate website can access. When one logins,
one simply remembers which images to click on among a set of
others that aren`t part of one`s password.

A phisher who wants to trick you into giving up your
PhorceField password knows nothing about the secret images,
and so must present one with a huge number of possibilities in
the hope of getting the right set of pictures.

This means that one will struggle to identify the correct
ones -- one might remember that the password includes a loaf
of bread, but was it round or oblong? A close shot, or taken at a distance? Eventually, after a number of failed logins, you will just give up and leave the
phishing site without ever having revealed your password, say
the researchers.

The researchers tested PhorceField on 23 users and found
that 76 per cent failed to reveal even a single image from
their password during a phishing attempt, and none revealed
the entire password -- for once, being forgetful pays off.

They will present their work at the Annual Computer
Security Applications conference in Orlando, Florida, next
month.
