PriS is a security and privacy requirements engineering method which aims on incorporating privacy requirements early in the system development process. Specifically, PriS provides a set of concepts for modelling privacy requirements in the organisation domain and a systematic way-of-working for translating these requirements into system models. In this paper we present the PriS conceptual framework and a case tool that assist PriS way of working the PriS-Tool. Specifically, PriS-Tool assist developers by offering design capabilities of the organization’s goal-process model, helps them to monitor the impact of privacy requirements on organisation’s goals and processes, suggests them a set of implementation techniques for the realization of the privacy related processes and offers guidance throughout this process.
