This article presents the results of a trend-scouting study on the applicability of contemporary information privacy and information security research in future defence scenarios in a 25-year-horizon. The authors sketch the expected digital warfare and defence environment as a‘Battlefield of Things’ in which connected objects, connected soldiers, and automated and autonomous sensing and acting systems are core elements. Based on this scenario, the authors discuss current research in information security and information privacy and their relevance and applicability for the future scenario.
