摘要：The central idea of the work on the subject matter is to lessen the password guessing attack in a
computer protection technique by developing graphical passwords for which pixels are selected from pictures having
some unique sound effects coupled with a password. In a computer protection technique, human-computer
communication relies on good authentication of the method. For the attackers, impressive passwords are easy to guess.
For this reason, research workers of present days preferred the technique in which graphical pictures are used as
passwords. Human brain recalls picture better than textual character. Recent certification methods go through many
weak points. Therefore, graphical passwords are developed using pictures or representation of pictures.
