Live Object for Securing Graphical Passwords

Abstract

To apply more safety to the cloud system, Live Object for a securing graphical password is a new
graphical watchword scheme for public terminals that replaces the static digital images typically used in graphical
password systems with personalized physical tokens, here in the form of digital pictures displayed on a physical userowned device such as a mobile phone. Users represent these images to a system camera and then enter their password
as a sequence of selections on live video of the toke. The reliability study shows that image feature based passwords
are viable and suggests appropriate system thresholds password items should contain a minimum of seven features, 40
percent of which must match originals stored on an authentication server in order to be judged equivalent. The
usability study measures task completion times and error rates, revealing these to be 7.5 and 9 percent, broadly
comparable with prior graphical password systems that use static digital images.
