A K-Anonymity Privacy-Preserving Location Monitoring System for Wireless Sensor Networks With Nymble Secure System

Anonymizing wireless sensor networks allow users to access services privately by using a series of routers to hide the client's IP address from the server. As a result, administrators block all known exit nodes of anonymizing networks, denying anonymous access to misbehaving. To address this problem, servers can "Blacklist" misbehaving users, thereby blocking users without compromising their anonymity. Monitoring personal locations with a potentially untrusted server poses privacy threats to the monitored individuals, a privacy-preserving location monitoring system for wireless sensor networks is adopted.
