Abstract

A novel method for image-based authentication (IBA) in a mobile device framework is proposed and evaluated. Often, the users desire for a reliable and user-friendly authentication makes systems vulnerable and hinders the achievement of World Wide Web e-services. In particular, the development of Mobile Internet requires the definition of a user authentication system that satisfies all the requirements of security and usability and does not requires specialized hardware. If on the one hand graphical passwords are easier to recall than traditional alphanumeric passwords, on the other hand the wireless environment imposes severe constraints on data transmission capability and user friendliness, which are satisfied in the system devised.
