<i>K</i>-anonymity scheme for privacy preservation in location-based services on IoT environment

Abstract

Location-based services have important impacts on many applications of internet of things. In these services location of users are revealed in front of third party server that makes the privacy of user vulnerable. It is required to collect real time data regarding ongoing events to response the query of user. Wireless sensor network is most popular to collect the data sensed by the sensor nodes and assist the third party server to response the query of user. The energy constraint sensor nodes motivate the researchers to design energy efficient routing. This paper introduces two schemes for two different aspects of internet of things environment. First one is a k-anonymity-based privacy preservation scheme for quality query response service and second one is an energy efficient secure routing scheme to collect real time data from sensor nodes in order to response the query of user. The performance analysis shows that the proposed scheme performs better with compared to existing schemes.
