Recent years have seen vast global increases in computing power and mobile networking. At the same time, huge numbers of sophisticated sensors, “smart devices”, and cyber physical social machines have created similarly vast increases of related data. Scattered across multiple domains and in a variety of formats-e.g. healthcare, smart cities, smart home, networked mobile and wearable devices, connected industry-these data constitute countless information sources. As such, they may be shared and recombined to offer opportunities for socioeconomic improvements in our homes, workplaces, and cities. At the same time, they present risks to privacy, trust, and ethical behaviour in our communities. These technologically enabled opportunities and risks create cybersecurity tensions that the current project seeks to address and mediate.
