Privacy requirements patterns for mobile operating systems

Nowadays mobile devices have rapidly developed. Privacy protection for mobile operating systems has become a hot topic in industry and research, which also brings new challenges. The scenarios in mobile operating systems are different from those in tradition systems. Users of mobile systems face more and more new risks in new scenarios. On the other hand, personal data is growing exponentially every day. It reminds us the importance of privacy protection is also increasing at the same time. In this paper, we study the privacy patterns for mobile operating systems. We elicit privacy-related requirements in three ways - knowledge from domain experts, literature review on public documents of existing mature systems and feedback from real users. Based on these requirements, we propose 7 privacy patterns which are presented with the RePa Requirements Pattern Template. All of these patterns were refined by professional business analysts which concrete the result of our work. We believe that our findings can help business analysts with the description for privacy requirements in future mobile operating system development projects.
