Towards the Design of Usable Privacy by Design Methodologies

As privacy engineering gains much attention, recently literature records a number of methodologies that support software designers to model privacy - aware systems starting from the early stages of the software lifecycle until the late design stages prior to implementation. However, in order for these methodologies to be used and applied successfully from system engineers, it is important to be developed following a number of existing usability criteria for increasing designers' acceptance and performance. In this paper, we, initially, identify the set of usability criteria presented in the respective literature and examine how the existing privacy requirement engineering methodologies conform with these usability criteria. The results show that most methodologies conform with a number of criteria but still there are opportunities for further improvements.
