Given that phishing is an ever increasing problem, a better authentication system than the
current alphanumeric system is needed. Because of the large number of current
authentication systems that use alphanumeric passwords, a new solution should be
compatible with these systems. We propose a system that uses a graphical password
deployed from a Trojan and virus resistant embedded device as a possible solution. The
graphical password would require the user to choose a family photo sized to 441x331
pixels. Using this image, a novel, image hash provides an input into a cryptosystem on
the embedded device that subsequently returns an encryption key or text password. The
graphical password requires the user to click five to eight points on the image. From
these click-points, the embedded device stretches the graphical password input to a 32-
character, random, unique alphanumeric password or a 256-bit AES key. Each
embedded device and image are unique components in the graphical password system.
Additionally, one graphical password can generate many 32-character unique,
alphanumeric passwords using its embedded device which eliminates the need for the
user to memorize many passwords. / Computer Engineering
