Security Engineering

Hi, I need assistance in the following problem please? An increasingly common mechanism is to ask for several pieces of security information rather than one. A call center might ask not just for your mother’s maiden name, a password, and the amount of your last purchase, but also your dog’s nickname and your favorite color. Such schemes need careful evaluation of their usability and effectiveness using the tools of applied psychology. Design such a password protocol and evaluate its usability and effectiveness. (A verbal text description is enough.) Best Regards, Vishnu Vandana
