Preserving Confidentiality in Wireless Medical Data

In recent times, healthcare applications are widely being used for remote patient monitoring and in hospitals using wireless sensor networks. Wireless medical sensor networks are highly vulnerable to different kind of attacks such as eavesdropping, modification, data breach etc which is a potential threat to patient sensitive physiological data. Security for wireless medical sensor networks is one of the major requirements in order to attain few issues like authentication, integrity and confidentiality. A considerable measure of work has been done to secure wireless medical sensor networks. The existing healthcare solutions can protect information amid transmission but in any case fails to stop inside attack where the sensitive patient data will be revealed by the malicious database administrator. The proposed system presents a practical approach to overcome this issue by making use of multiple data servers for storing patient sensitive data. The primary contribution of this system is secure transmission of patient sensitive data to multiple data servers and performing statistical analysis on the patient data using Paillier cryptosystem and EIGamal cryptosystems by ensuring patients’ privacy.
