摘要：We propose a isolationprotection location auditing system for wireless sensor networks. Auditing personal locations with entrusted server poses isolation threats to the monitored individuals. We use two network location anonymization algorithms, namely, resource and qualityaware algorithms that aim to enable the system to provide high quality location auditing services for system users, while protection personal location isolation. Both algorithms depend on established kanonymity isolation concept, that is, a person is similar persons, to enable sensor nodes to provide the aggregate location information of monitored persons for the system. To utilize the aggregate location information to provide location auditing services, we use a spatial histogram that estimates the distribution of the monitored objects based on the gathered aggregate location information. Then the estimated distribution is used to provide location auditing services through answering range queries. The results show that our system provides high quality location auditing services for system users and guarantees the location isolation of the monitored persons.
