Privacy preservation using Geometric Data perturbation and fragmentation approach in Wireless Sensor Networks

Privacy preservation is of great concern in Wireless Sensor Networks. One of the major issues is the privacy of the data collected and transmitted from the sensor nodes in wireless sensor networks. This paper presents Geometric Data perturbation to transmit the information in a secured manner so that both the external and internal adversary is prevented from eavesdropping. In addition to the above, fragmentation approach is suggested for storing the sensitive data in the data centres of Wireless senor networks. This fragmentation approach does not secure the data from an intruder, but prevents the utilization of the data when captured.
