A Privacy-Sensitive, Situation-Aware Description Model for IoT

This chapter discusses the impact of the ``calm’' invasion of the Internet-of-Things (IoT) on people’s private lives to the extent that the expected benefits of IoT have become a concern to people. To mitigate this impact, this chapter presents a Model-Driven Architecture (MDA)-based approach for injecting privacy concerns into thing specifications so that things would become alert to these concerns and, hence, would act accordingly. Being alert should mean a better assessment of what needs to be done, when, and where before violating any privacy policies. For illustration and demonstration purposes, WoT Thing Description (WoT TD) is adopted as an example of W3C thing specification. To make things aware of situation-related privacy concerns, the approach presented in this chapter defines SituationPrivacy metamodel, merges SituationPrivacy and WoT TD metamodels into SituationPrivacyWoTTD metamodel, and, finally, generates SituationPrivacyWoTTD model using an in-house case tool. Privacy concerns and the MDA approach that addresses these concerns are illustrated and demonstrated with a case study about a care center for elderly people.
