Enforcing privacy through usage-controlled video surveillance
Pascal Birnstill, Alexander Pretschner · 2013
Increasing capabilities of intelligent video surveillance systems require the enforcement of privacy-related requirements. Data usage control technologies offer appropriate solutions in this problem domain. We first present specific requirements for a privacy enforcement infrastructure for modern surveillance systems that we align with a generic architecture and a privacy-aware workflow template for operating such systems. To ensure the compliance of a surveillance system's operation with such a workflow, we then derive respective usage control requirements. We show that the conceptual framework of usage control provides suitable instruments for specifying these requirements and for implementing the corresponding enforcement mechanisms. Our architecture has been implemented prototypically.
