A review: Preserving privacy in wireless sensor networks

This review paper concentrates on preserving privacy in wireless sensor networks. In this system, two location anonymization algorithms has been proposed, namely, resource and quality aware algorithms, that aim to enable the system to provide high quality location monitoring services for system users, while preserving personal location privacy. Both algorithms rely on the well established k-anonymity privacy concept, that is, a person is indistinguishable among k persons, to enable trusted sensor nodes to provide the aggregate location information of monitored persons for our system. Privacy is typically addressed through privacy policies, which inform the user about a service provider´s data handling practices and serve as the basis for the user´s decision to release data. This paper studies privacy through a distributed anonymity algorithm that is applied in a sensor network, before service providers gain access to the data.
