Even if its goal is to provide general techniques with a potentially broad impact, CAPPRIS must, by nature, consider different contexts and concrete case studies to ensure the relevance and significance of its results. To reach this aim, three classes of case studies have been selected: Online Social Networks (OSN), Location Based Services (LBS) and Electronic Health Record Systems (EHR), which correspond to application domains with great impact on society. Depending on the evolution of the technologies and their usages, CAPPRIS may decide during the course of the project to consider other case studies that could become more critical or challenging.
