The Internet of Things (IoT) seeks to embed computation in mundane objects - pill bottles, shelves, weighing scales, etc. - and connect these 'things' to the internet to enable a broad range of new and improved services (e.g. improved healthcare services). The IoT will open up a wealth of personal data - biological data, data about our physical movements around the home, or interaction with objects therein, etc. - distributing it seamlessly across the internet. The seamless distribution of personal data presents real challenges to the adoption of the IoT by users, however.
