Reverse Privacy Engineering

Facing the problems of personal data industrialization, many technical and legal solutions have been proposed. Pro-privacy legislation and new design patterns try to make engineers and merchants more responsible. Although these efforts must be maintained from these actors, we believe that such a consideration for privacy, focused on commercial transactions, leaves the individual subjects and their social interactions at the deadlock. We suggest reversing privacy engineering by empowering users in context. Thus we propose to model privacy among the concept of “privatory framework” [11], then compare face-to-face and computer-mediated privatory frames, mainly in social network sites (SNS). From these results, we can discuss technical potential allowing the user to completely define privatory framework of her computer-mediated social interactions.
