Building blocks for identity management and protection for smart environments and interactive assistance systems

Interactive environments are more and more entering our daily life. Our homes are becoming increasingly smart and so do our working environments. Aiming to provide assistance that is not only suitable to the current situation, but as well for the involved individuals usually comes along with an increased scale of personal data being collected/requested and processed. While this may not be exceptionally critical as long as data does not leave one's smart home, circumstances change dramatically once smart home data is processed by cloud services, and, all the more, as soon as an interactive assistance system is operated by our employer who may have interest in exploiting the data beyond its original purpose, e. g. for secretly evaluating the work performance of his personnel. In this paper we discuss how a federated identity management could be augmented with distributed usage control and trusted computing technology so as to reliably arrange and enforce privacy-related requirements in externally operated interactive environments.
