A Lexicon for Privacy in Video Media Spaces

Video media spaces are an excellent crucible for the study of privacy. Their design affords opportunities for misuses, prompts ethical questions, and engenders grave concerns from both users and non-users. Despite considerable discussion of the privacy problems uncovered in prior work, questions remain as to how to design a privacypreserving video media space and how to evaluate its effect on privacy. The problem is much more deeply rooted than this, however. Privacy is an enormous concept and from it emerges an overwhelming torrent of interrelated words. In this article, we draw from resources in environmental psychology and CSCW to build a broadlyand deeply-rooted holistic description of this nebulous thing, privacy. Beyond this, we relate the vocabulary back to the real and hard problem of designing privacy preserving video media spaces. In doing so, we facilitate exploration and discussion of the privacy-design relationship.
