Comparing Privacy Requirements Engineering Approaches

Several privacy requirements engineering approaches exist, which differ in notions and terminology. We extended a conceptual framework originally designed to compare security requirements engineering approaches with concepts and notions used in privacy requirements engineering. Furthermore, we apply our conceptual framework to compare and evaluate current privacy requirements engineering approaches, e.g., the PriS and LINDDUN approaches. We discuss how these methods are related to the conceptual framework. We compare the terminology and notions of these methods with the clear-cut vocabulary of the conceptual framework.
