Abstract:
In this contribution, we present an approach to encounter various challenges of the growing amount of media available in our digital society as well as an individual’s need to access structure and ordered information presents applying the Semantic Ambient Media Framework. The framework extends digital media, devices and applications, as well as services and with digital meta-data, interconnects them through semantic models, and makes them accessible in a Web-based API. In the event the API is accessed, the framework’s services tailor the media, depending on context they are used in, their semantic interconnection with other media, and the specific application, device, and context they are accessed from. A possibility to access the information stored within the Semantic Ambient Media Framework is showing media on public displays. In order for public displays to deliver private, personalized, or sensitive contents or provide access to user-specific functionality, authentication mechanisms are required. On public displays, authentication is 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, no actual credentials have to be typed in on the public display, as this makes use of the users’ personal mobile devices and works with a one-time and location-based code. This contribution illustrates the concept and system architecture of the Semantic Ambient Media Framework in a working scenario together with multi-factor authentication for public displays that protects against threads, such as shoulder surfing, thermal attacks, or smudge attacks, which we also illustrate. We conclude with an outline of future work.
