Abstract :
Current technology is more than capable of offering a secure authentication process, but users are confined in their ability to remember difficult words and form judicial decisions about security. In this thesis, both of these problems were addressed in the maturation of a new video-password scheme. Subject areas in computer security, password usability, and cognitive psychology were referenced throughout the plan procedure. Four new images based, password authentication systems are proposed here. The user survey for third and fourth schemes of password authentication based on images is presented in this dissertation. The fourth strategy was tested against character passwords of equal complexity and recall was measured over a seven-day period. The outcomes of the study indicate that a picture password system which accepts input without respect to society can be both safe and memorable. Both quality and picture passwords were randomly assigned from a password space of almost 29 billion possible passwords.
