Abstract:
In our interconnected society, public displays deliver private and personalized content. This presents the need to authenticate users in order to protect personal and private information or sensitive contexts of use. In general, authentication mechanisms on public displays are subject to a number of risks, especially, if displays offer multi-touch interfaces or grow even larger. In this contribution, we present a multi-factor authentication system for public displays using the Semantic Ambient Media Framework. In our approach, at first, users use their personal mobile devices, such as smartphones or tablets, to authenticate themselves securely. On the smartphone, a graphical code is displayed, which the user enters on a grid shown on the public display. In a last step, the user confirms the authentication on his smartphone. The code displayed on the smartphone is a one-time and location-based code and no actual credentials have to be typed in on the public display. Thus, this method protects against threads, such as shoulder surfing, thermal attacks, or smudge attacks.
