E-health, namely the application of ICT in health, is aimed at gathering, analyzing and storing clinical data in all formats and exchanges those data between health agents and insurers. The service of e-health incorporates telemedicine concept, tele-counseling, portable electronic devices and medical portals, which involve the acceptance of innovative technologies for the collection and use of sensitive medical data. This thesis studies the use of cloud computing technology in healthcare systems due to high flexibility, scalability and return of investment (ROI). Additionally, network servers, storage facilities, databases and cloud’s infrastructure and services offer an attractive platform for cooperation of all health facilities, first nationally and then globally. On the other hand, one major drawback is that cloud computing comes into conflict with privacy laws and security of sensitive patient data in case of security breach (impact: an opponent could gain access to all medical records). The thesis is structured into four main chapters that incorporate the concept of cloud computing and its usefulness in healthcare systems. Precisely, the first chapter includes the concept of cloud computing, its models and its features, while the second analyzes the threats, the risks and the security on it. The third chapter analyzes the conditions defined by HIPAA for implementing cloud computing in healthcare systems and demonstrates the implementation of telemedicine through the use of cloud computing model. Finally, the fourth chapter applies a healthcare model on infrastructure as a service acting as a private cloud and providing healthcare services while ensuring mechanisms to meet security and privacy requirements on patient data.
