Privacy Preservation in WSN for Healthcare Application

Abstract Wireless Sensor Networks (WSN) based healthcare systems are increasing day by day to advise the health status and living environment habitat of peoples. However, WSN based healthcare application suffers from the issues related to privacy and security. Susceptible attacks and security consideration comes into WSN based healthcare applications as an interesting and challenging problem. In this paper, we have proposed a privacy preservation scheme for WSN based healthcare application utilizing the principles of multipath routing, secret sharing and hashing. The healthcare data collected from the wireless sensor network is splits into n components. Further, the hash value is computed for each component with the help of well-known hashing technique. The change in hash value is used to detect changes in the message. These n components are then transferred to n servers, with the help of multipath routing. This article provides extensive simulations to validate new approach. Results show that secret splitting along with multipath routing helps to attain privacy preservation in WSN based healthcare system.
