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. temporal privacy techniques, the location privacy is split into data source and base station techniques. (1) This paper provides an overview of ongoing research activities, various design issues involved and possible solutions incorporating these issues. This paper (2) explains WSN is an emerging technology that shows great promise for various futuristic applications both for mass public and military and studies the security aspects of these networks. The paper (3) discusses about classification of WSN and challenges of the Next Generation WSN. The paper (4) says increasing demand for security and automated monitoring of things and places makes WSNs a promising technology. (5) Says monitoring personal locations with a potentially untrusted server poses privacy threats to the monitored individuals. The (6) author takes an example such as a hospital or bank, needs to share person-specific records in such a way that the identities of the individuals who are the subjects of the data cannot be determined. (7) Proposes an anonymous communication technique to protect the location privacy of the users of location-based services. (8) Paper tackles a major privacy threat in current location-based services where users have to report their exact locations to the database server in order to obtain their desired services. In this paper, we propose a privacy preservation of such mobile users with the help of anonymization and by reporting aggregate location. An anonymization means a person is indistinguishable amongst k persons in a network. The most effective way to compromise location privacy used by adversary is packet-tracing. In such an attack, an adversary can locate the immediate nodes by eavesdropping the transmitted packet, and further reduce the flow direction of packets. Along with privacy preservation of mobile users we are monitoring location of any mobile user through our system.
