DPI and Canadians’ Reasonable Expectations of Privacy

canadasupremecourt[Note – I preface this with the following: I am not a lawyer, and what follows is a non-lawyer’s ruminations of how the Supreme Court’s thoughts on reasonable expectations to privacy intersect with what deep packet inspection (DPI) can potentially do. This is not meant to be a detailed examination of particular network appliances with particular characteristics, but much, much more general in nature.]

Whereas Kyllo v. United States saw the US Supreme Court assert  that thermal-imaging devices, when directed towards citizens’ homes, did constitute an invasion of citizens’ privacy, the corresponding Canadian case (R. v. Tessling) saw the Supreme Court assert that RCMP thermal imaging devices did not violate Canadians’ Section 8 Chart rights (“Everyone has the right to be secure against unreasonable search or seizure”). The Court’s conclusions emphasized information privacy interests at the expense of normative expectations – thermal information, on its own, was practically ‘meaningless’ – which has led Ian Kerr and Jena McGill to worry that informational understandings of privacy invoke:

Draft – Who Gives a ‘Tweet’ About Privacy?

twittercapacityThis is a full draft of the paper on Twitter and privacy that I’ve been developing over the past few weeks, entitled ‘Who Gives a ‘Tweet’ About Privacy?’ It uses academic privacy literature to examine Twitter and the notion of reasonable expectations of privacy in public, and is written to help nuance privacy discussions surrounding the discourse occuring on Twitter (and, implicitly, similar social networking and blogging sites). The paper focuses on concepts of privacy and, as such, avoids deep empirical analyses of how the term ‘privacy’ is used by particular members of the social networking environment. Further, the paper avoids delving into the web of legal cases that could be drawn on to inform this discussion. Instead, it is theoretically oriented around the following questions:

  1. Do Twitter’s users have reasonable expectations to privacy when tweeting, even though these tweets are the rough equivalent of making statements in public?
  2. If Twitter’s user base should hold expectations to privacy, what might condition these expectations?

The paper ultimately suggests that Daniel Solove’s taxonomy of privacy, most  recently articulated in Understanding Privacy, offers the best framework to respond to these question. Users of Twitter do have reasonable expectations to privacy, but such expectations are conditioned by juridical understandings of what is and is not reasonable. In light of this, I conclude by noting that Solove’s use of law to recognize norms is contestable. Thus, while privacy theorists may adopt his method (a focus on privacy problems to categorize types of privacy infractions), they might profitably condition how and why privacy norms are established – court rulings and dissenting opinions may not be the best foundation upon which to rest our privacy claims – by turning to non-legal understandings of norm development, degeneration, and mutation.
