Abstract: Diffusion of Innovations in Health Care: Identifying Opinion Leaders and the Network of Influence Between Physicians Advisors Dr. Jordi Duch, Dr. Robert Rallo External Co-Advisors Dr. Xavier Guardiola Student Alexandre Vinyals Valdepeñas Itinerary MSISI-Security Keywords Clustering, Diffusion, Big Data, Knowledge Management, User Profiling Summary This thesis identifies of Opinion Leaders and the network of influence between them. This is possible due to medical prescription databases containing a detailed description of the diffusion processes occurring in health care organization. The thesis shows the detailed process, from the characterization of the database, identification of diffusion curves, construction of intermediate models and the final inference process. At the same time we highlight the privacy related problems of the current prescription system, and a group signature scheme is proposed to palliate those privacy issues.
