The Internet of Things (IoT) approach to interconnected devices has become a significant topic in recent years, and is likely to be a major influence on future networking standards, such as ongoing work on 5G. IoT introduces connectivity to a much wider range of devices than seen previously, which raises a number of challenges, both technical and ethical. This paper explores some of these challenges which IoT faces, as a result of the personal and confidential information which may be transmitted from body-worn sensors, and the inherent challenges of introducing connectivity to standalone devices, rather than to equipment operated by users.
