Computer human interaction is nowadays shifting from traditional desktop computers and standalone applications towards mobile computing devices and cloud-based oriented applications and services, mainly triggered by developments in network communication technologies. Within this realm, Security and Privacy issues of interactive systems are considered of paramount importance as it is known that the consequences of a security breach can harm the credibility and legal liability of an organization, leading to loss of users' trust and acceptance while it exponentially increases maintenance and support costs. This talk will provide a brief survey of the combined area of usable security based on state of the art research in this field. Among others, the relationship between usability and security will be investigated with concrete case studies in this area like (Authentication mechanisms, CAPTCHA challenges "Computer Automated Public Turing test to tell Computer and Humans Apart" etc.)
