An Object- and Task-Oriented Architecture for Automated Video Surveillance in Distributed Sensor Networks

Enforcing privacy through usage-controlled video surveillance

“…We chose two scenarios for demonstrating usage control enforcement in the video surveillance testbed NEST [6].…”

“…Moreover, the utilization of anonymization techniques can hardly be reflected in a generic workflow, as the achievable gain for privacy as well as the appropriate de- We now outline a generic architecture for privacy-aware surveillance systems. Generalizing earlier work [3,6], our abstraction subsumes many approaches to surveillance architectures in the literature.…”

“…Resting on the work of Hampapur et al [3] and Monari et al [6], we derive a generic architecture, which serves the purpose of discussing and illustrating how usage control enforcement mechanisms have to be integrated into such systems.…”

“…Our contribution is privacy enhancing technology for surveillance cameras that (1) works on object streams, (2) is always switched on yet privacy-friendly as long as no alarm is automatically triggered, and (3) is not directly bound to a purpose that would be hard to capture, but rather relies on the notion of distinct operational modes. As a proof of concept, we implemented usage control enforcement for several components of the video surveillance testbed Network Enabled Surveillance and Tracking (NEST) [6].

Task-Oriented Object Tracking in Large Distributed Camera Networks

“…As a solution for the internal structure of such a system, in [5] an architecture, for task-oriented data processing, has been proposed (sketched in Fig. 1).…”
