"We propose PRISM CODE project (PRIvacy and Security for Mobile COoperative DEvices). The aim of this project is to design some of the fundamental tools for privacy and security of the upcoming distributed services, which are built upon the cooperation of mobile personal devices like smartphones, PDAs, or tablets. In analogy with the geometric prism which is built on two parallel bases, we believe that a wide adoption of cooperative services for mobile devices is possible only on the following two bases, to be present at the same time: privacy, to give to the users and other stakeholders some confidence that no private information will be disclosed by taking part in those services; and security, to guarantee (to some extent) that the services will not be exploited in a malicious way (e.g. having no money loss for stakeholders).This four-year project will be executed by Dr. Mauro Conti (as Principal Investigator) at the University of Padua, Italy, which recently granted him a stable research post as Assistant Professor. This position is subject to an evaluation after the third year. Upon a positive evaluation, the position will becomes permanent. This grant will improve considerably the research results of the fellow, hence the prospects for his permanent integration."
