Knowledge-Based Authentication using Twitter Can We Use Lunch Menus As Passwords?

ManabuOkamoto, Kanagawa Institute of Technology, Japan

ABSTRACT

The vast majority of online servicesrequire some form ofpersonal authentication. Unfortunately, standard password authenticationstrikes a poor balance between security and convenience, whereas strongerauthentication schemes,such as those involvingbiometrics, one-time passwords, and electronic certificates, depend on specialized hardware and/orhardware tokens. To achieve convenience, robustness, and cost-effectiveness together, we propose a scheme for dynamicknowledge-based authentication in which Twitter direct messaging is used to collectsimple, memorable question/answer pairs. We also conduct a user study to evaluate the proposed scheme.
