A UML Profile for Privacy Enforcement

Nowadays most software applications have to deal with personal data, specially with the emergence of Web-based applications, where user profile information has become one of their main assets. Due to regulation laws and to protect the privacy of users, customers and companies; most of this information is considered private, and therefore convenient ways to gather, process and store them have to be proposed. A common problem when modeling software systems is the lack of support to specify how to enforce privacy concerns in data models. Current approaches for modeling privacy cover high-level privacy aspects to describe what should be done with the data (e.g., elements to be private) instead of how to do it (e.g., which privacy enhancing technology to use); or propose access control policies, which may cover privacy only partially. In this paper we propose a profile to define and enforce privacy concerns in UML class diagrams. Models annotated with our profile can be used in model-driven methodologies to generate privacy-aware applications.
