The book ‘Reversed Surveillance’ is a visualisation of invasive surveillance technologies, challenging the prospect of automating crime detection during protests in France. The project reflects on the development and legislation of mass surveillance by offering a case study on how individuals can protect themselves using the very tools with which they are surveilled. The project bases on the idea that since it is unlikely to fully revert surveillance and its effects on society, society should explore ways to reverse its impact. In ‘Reversed Surveillance’, Marcel Top demonstrates the potential of reversing surveillance dynamics to protect the right to protest: by gaining knowledge of accessible surveillance tools, it is possible to ensure police accountability.
