Presence Metadata in the Internet of Things: Challenges and Opportunities

The Internet of Things is an emerging computing paradigm that promises to revolutionise society. The widespread capture and aggregation of data from sensors and smart devices combined with processing using machine learning in cloud computing platforms provides unrivalled insights into our environment. In addition to the numerous benefits (smart healthcare, cities, transportation, etc.) such insights potentially jeopardise the privacy of individuals, organisations, and society as whole. This is despite UK and EU regulations attempting to mitigate the risk of individuals' data exposure and the impact of it on their security. To demonstrate the exploitation of metadata and its threat to privacy, this paper presents Meta-Blue, a Bluetooth Low Energy metadata capture, analysis, and visualisation tool. The results of a case study are combined with an overview of literature on IoT privacy to provide a holistic overview of the challenges and opportunities presented by IoT metadata.
