Health monitoring is repeatedly mentioned as one of the main application areas for pervasive computing. Mobile or remote Health Care is the integration of cloud computing and health monitoring. It is the application of cloud computing technologies for improving communication among patients, physicians, and other health care workers. Cloud-assisted health monitoring, which applies the prevailing mobile communications and cloud computing technologies to provide feedback decision support, has been considered as a revolutionary approach to improving the quality of healthcare service while lowering the healthcare cost. Unfortunately, it also poses a serious risk on both clients' privacy and intellectual property of Health service providers, which could deter the wide adoption of technology. I present a system is to address this important problem and design a cloud assisted privacy preserving health monitoring system to protect the privacy of the involved parties and their data. Moreover, the outsourcing decryption technique using email and a newly proposed re-encryption using blind search techniques are adapted to secure sensitive data of user.
