Description

Recently, with the rapid development and implementation of wireless medical sensors, electronic healthcare has gained increasing popularity. Monitor and record some vital parameters of patients are of importance to know the patient’s health condition. But malicious attacks happen occasionally, which may cause the patient- related data being leaked or modified. Wireless Sensor Networks (WSN) is an emerging technology that has the potential to transform the way of human life. Healthcare applications are considered promising fields for Wireless Medical Sensor Network, where patient’s health can be monitored using Medical Sensors. Wireless Medical Sensor Networks (WMSNs) are the key enabling technology in healthcare applications that allows the data of a patient’s vital body parameters to be collected by wearable biosensors. Current WMSN healthcare research trends focus on patient reliable communication, patient mobility and energy-efficient routing. Security and Privacy protection of the collected data is a major unsolved issue. To overcome these issues, symmetric algorithms and attribute based encryptions techniques are adopted, which secures the data transmission and access control system for MSNs. Our aim is to instigate discussion on these critical issues since the success of healthcare application depends directly on patient security and privacy, for ethic as well as legal reasons. In addition, we discuss the issues with existing security mechanisms, and sketch out the important security requirements for such applications. This project reviews existing schemes that have been recently proposed to provide security solutions in wireless healthcare scenarios. The system propose a practical approach to prevent the inside attack by using multiple data servers to store patient data.
