Designing a Social Protocol:
Lessons Learned from the
Platform for Privacy Preferences
The Platform for Privacy Preferences (P3), under development by the World
Wide Web Consortium (W3C), enables users and Web sites to reach explicit
agreements regarding sites data privacy practices. The options chosen
in developing the protocols, grammar, and vocabulary needed for an agreement
lead the authors to a number of generalizations regarding the development
of technology designed for "social" purposes.
In this paper we will explain the goals of P3; discuss the importance of
simplicity, layering, and defaults in the development of social protocols;
and examine the sometimes-difficult relationship between technical and policy
decisions in this domain.
