The present invention discloses a privacy-aware ambulatory healthcare system using one or more wireless body area networks (WBANs). The idea behind this invention is to provide majorly unmanned, automated, pervasive, remote, real-time ambulatory healthcare services. After getting into an ambulance, a patient would be made to wear a set of easy, light-weighted, and convenient wireless body sensor nodes which would form a WBAN, and would instantaneously initiate the capturing the patient’s physiological data. The invention is strongly dependent on cloud computing technology as the cloud servers serve as the primary hubs of storage and computation of the system. However, to address the issues related to privacy, security, and data confidentiality of cloud computing, the invention proposes to develop a completely blind cloud platform. To preserve the privacy of the medical data, an intelligent method is proposed to mask the identity of the patients, i.e., the users of the system, and thereby, obtaining unidentified data for storage and analysis.
