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.
