In a series of articles (and a NYT op-ed; my $.02 on that is here), Woddy Hartzog and several co-authors have been developing the concept of “obscurity” as a partial replacement for “privacy.” The gist of the argument, as explained by Hartzog and Evan Selinger in a recent anthology piece (“Obscurity and Privacy” (=OP, pagination to the ssrn version)), is that “obscurity is the idea that information is safe – at least to some degree – when it is hard to obtain or understand” (OP 2). This is because “we should not underestimate how much of a deterrent effort can be” (OP 2), and information that is hard to understand imposes similar costs in terms of effort. They argue that obscurity functions better as a concept than privacy, in part because it avoids the binarism associated with the public/private dichotomy:
“Because activities that promote obscurity can limit who monitors our disclosures without being subject to explicit promises of confidentiality, the tendency to classify information in binary terms as either ‘public’ or ‘private’ is inadequate. It lacks the nuance needed to describe a range of empirically observable communicative practices that exist along a continuum” (OP 4)
The public/private dichotomy has been the object of sustained criticism, in part because it does not track how people live their lives. For example, U.S. privacy law tends to regard information that an individual has voluntarily disclosed once as no longer private, as if the context of disclosure doesn’t matter at all. The obscurity argument is designed to start with this basic thought: we share information all the time, and do so with the expectation that others will manage it appropriately. This is Helen Nissenbaum’s point about the “contextual integrity” of information; it is also how Ari Waldman starts with his recent reformulation of privacy as trust. The general stability of these information and contextual flows is behind Lior Strahilevitz’s “social networks” account of privacy and its violation, as well as Dan Solove’s account of how suddenly viral spreads of information online occasions the need to rethink reputation.
