ABSTRACT
The project aims in developing a system which is very helpful for illiterates in
secure accessing, who are not able to remember passwords. Image based password
authentication for illiterates with touch screen interfacing provides an image based
security system, which can be installed in poultry forms, houses and all kinds of domestic
and industrial applications. The main aim of this project is to provide a security system
for illiterates. This system provides user-friendly environment for the users with a kind of
image interaction. Here the password need not be a string of characters it can use few
images; this may be easy for the illiterates to remember. This device makes use of a touch
screen sensor based graphical LCD which makes the things still easier. This project gives
us the exposure about how to efficiently make use of the touch screen technology to
interface with the appliances in our practical life. It can also be operated very easily with
the hand so can be used even by very old people and also by the illiterates.
Touch screens provide fast access to any and all types of digital media, with no
text-bound interface getting in the way. Faster input can mean better service. Using a
touch interface can effectively increase operator accuracy, reduce training time, and
improve overall operational efficiencies, thus keeping costs down, a properly designed
touch interface can improve each operator's accuracy. Touch screens are practical in
automation, which has become even simpler with touch screen technology. Owners
familiar with the icon system appreciate touch screens that make automation systems user
friendly.
In this project we make use of an onboard computer which has many input and
output ports. This Onboard computer is also termed as micro controller. All the input and
the output modules are interfaced with this control unit. The image input from the
graphical LCD is processed by the controller and provides access to the user if the
password received is correct
