THE USAGE OF GRAPHICAL PASSWORD AS A REPLACEMENT TO THE ALPHANUMERICAL PASSWORD
ABSTRACT: Alphanumerical
password is the password scheme that obligates the users to enter characters as
their password. In spite of its popularity, alphanumerical password usually can
be cracked easily when it is used by novice users. Since these users usually
type their password slowly, unauthorized person can get the password easily by
observing the movement of the users’ finger as they entering the password. A
graphical password is proposed to replace the alphanumerical password. From the
experiment it can be shown that none of users graphical password can be
cracked, meanwhile 80% of the users’ alphanumerical password can be cracked by
the researcher. However in average, users need only 4.68 seconds to enter the
password in alphanumerical password scheme, meanwhile in graphical password
scheme it takes about 39.06 seconds. Hence password entry in the graphical
password scheme needs about 8 times longer than in alphanumerical password.
Based on this fact, the graphical password may still be considered to be used
in applications that do not need a rapid password entry and the system security
is becoming the main issue.
