Abstract :
In this paper we present an experiment to detect the vulnerability of recognition based graphical authentication system to shoulder surfing. The experiment is conducted with teams of two, a user logging in to such as system and an observer who is trying to spot the user´s pass-image. Our results suggest that inputting our choice via the keyboard is more secure than using a mouse. We use three different ways of clicking keyboard input and find that they are all approximate equally secure.
