protecting critical environment is becoming more and more popular. On the one
hand, video surveillance systems should be able to detect the presence of
unauthorized people in the monitored environments to provide effective
physical security. On the other hand, video surveillance systems should be
also able to preserve the privacy of authorized people. Moreover, some
scenarios require that the right of a person to stay in a monitored room
depends on dynamic factors that change over time. To consider these aspects, our
paper proposes a video surveillance framework based on the Usage Control
model. This framework enforces security policies which continuously control
that the people who enter the monitored environment have the permission to
stay there. Then, we present two solutions to make our video surveillance
framework privacy-preserving. The first solution considers that when the
security policy is violated, the video surveillance system records the video
stream captured by the video cameras installed in the monitored environment.
The second solution uses the Secure-Two party Computation technique to
identify the people in the monitored environment in a privacy-preserving way.
In this paper, we present the architecture of the proposed framework, we
provide an example of Usage Control policy in a real scenario and we describe
the main details of our two implementations. Keywords: Video Surveillance, Privacy, Usage
