Fine-Grained Access Control Enabling Privacy Support in Wireless Sensor Networks
Wireless Sensor Networks (WSNs) are deployed to cover a wide range of scenarios ranging from environmental monitoring to medical applications. However, some deployments raise privacy concerns. The threats to privacy are directly identifiable in people-centric scenarios. However, environment-centric scenarios may also threaten the privacy of persons located in the monitored environment, as their current activity could be extracted from sensor data. To ensure that the deployed WSNs are well-received in their communities, respecting privacy is a condition sine qua non. Within the scope of this paper, the authors propose to involve the concerned people in the privacy decisions by introducing a fine-grained access control.
