Abstract: In this dissertation, we give a systematic study on ensuring data security and especially individual privacy in health care systems. To meet the varying demands of health care applications, we first unify various user authentication techniques into a coherent organizational trust infrastructure, providing flexible authentication services to health care organizations. Next, we present a remote login scheme that allows a health care organization to provide a certain service to its users, in such a way that the users can access the service from off-site locations in an anonymous manner. We then proceed to investigate a routine health care procedure, medication prescription, which involves multiple parties. Our focus is to clarify and address privacy concerns involved in medication prescription while enabling relevant parties to collect prescription data for purposes such as cost-effectiveness research. Finally, we combine binning and digital watermarking into a unified framework for attaining the dual goals of privacy and ownership preserving of health data in outsourcing.
