Abstract—Wireless sensor networks monitoring personal locations are identified through internet server. If server is untrusted, it may cause threats pertaining to privacy of individuals being monitored. In this work, we propose a privacy preserving location monitoring system for wireless sensor networks. Here, we design two in-network anonymization algorithms which aim to enable the system to provide high quality location monitoring services, while preserving personal location privacy and algorithms rely on the well-established n-anonymity privacy concept. For the location monitoring system using identity sensors, the sensor nodes report the exact location information of the monitored persons to the server; thus using identity sensors immediately poses 3 major privacy breaches. To tackle such a privacy breach, the concept of aggregate location information, that is, a collection of location data relating to a group or category of persons from which individual identities have been removed has been suggested as an effective approach to preserve location privacy.
Index Terms—Wireless sensor network location monitoring, privacy preservation anonymity network resource aware, quality aware.
