Privacy

Rendering CCTV (Somewhat) More Transparent

/ Christopher Parsons

CCTV meets consumerismIn a conversation with Prof. Andrew Clement this summer we got talking about the ever-increasing deployment of CCTV cameras throughout Canada. The conversation was, at least in part, motivated by the massive number of cameras that are being deployed throughout Vancouver with the leadup to the 2010 Olympic games; these cameras were one of the key focuses of the 10th Annual Security and Privacy Conference, where the BC Privacy Commissioner said that he might resign if the surveillance infrastructure is not taken down following the games.

I don’t want to delve into what, in particular, Prof. Clement is thinking of doing surrounding CCTV given that I don’t think he’s publicly announced his intentions. What I will do, however, is outline my own two-pronged approach to rendering CCTV a little more transparent. At the onset, I’ll note that:

  1. My method will rely on technology (augmented reality) that is presently only in the hands of a small minority of the population;
  2. My method is meant to be more and more useful as the years continue (and as the technology becomes increasingly accessible to consumers).

The broad goal is the following: develop a set of norms and processes to categorize different CCTV installations. Having accomplished this task, a framework would be developed for an augmented reality program (here’s a great blog on AR) that could ‘label’ where CCTV installations are and ‘grade’ them based on the already established norms and processes.

Google Dashboard – Does It Need Another Name?

/ Christopher Parsons / 6 Comments

TheWrongGoogleDashI like to pretend that I’m somewhat web savvy, and that I can generally guess where links on large websites will take me. This apparently isn’t the case with Blogger – I have a Blogger account to occasionally comment on blogs in the Google blogsphere, but despise the service enough that I don’t use the service. I do, however, have an interest in Google’s newly released Dashboard that is intended to show users what Google knows about them, and how their privacy settings are configured.

Given that I don’t use Blogger much, I was amazed and pleased to see that there was a link to the Dashboard in the upper-right hand corner of a Blogger page that I was reading when I logged in. Was this really the moment where Google made it easy for end-users to identify their privacy settings?

Alas, no. If I were a regular Blogger user I probably would have known better. What I was sent to when I clicked ‘Dashboard’ was my user dashboard for the blogger service itself. This seems to be a branding issue; I had (foolishly!) assumed that various Google environments that serve very different purposes would be labeled differently. In naming multiple things ‘dashboard’ it obfuscates access to a genuinely helpful service that Google is now providing. (I’ll note that a search for ‘Google Dashboard’ also calls up the App Status Dashboard, and that Google Apps also has a ‘Dashboard’ tab!)

Thinking About a ‘Privacy Commons’

/ Christopher Parsons / 7 Comments

unclesamsurveillanceIn some privacy circles there is a vision of creating a simple method of decoding privacy policies. As it stands, privacy policies ‘exist’ in a nebulous domain of legalese. Few people read these policies, and fewer still understand what they do (and do not) say. The same has traditionally been true of many copyright agreements. To assuage this issue surrounding copyright, the creative commons were created. Privacy groups are hoping to take some of the lessons from the creative commons and apply it to privacy policies.

I need to stress that this is a ‘thinking’ piece – I’ve been bothered by some of the models and diagrams used to express the ‘privacy commons’ because I think that while they’re great academic pieces, they’re nigh useless for the public at large. When I use the term ‘public at large’ and ‘useless’ what I am driving at is this: the creative commons is so good because it put together a VERY simple system that lets people quickly understand what copyright is being asserted over particular works. A privacy commons will live (or, very possibly, die) on its ease of access and use.

So, let’s think about use-value of any mode of description. The key issue with many commons approaches is that they are trying to do way too much all at once. Is there necessarily a need for a uniform commons statement, or is privacy sufficiently complicated that we adopt a medical privacy commons, a banking privacy commons, a social networking privacy commons, and so forth? Perhaps, instead of cutting the privacy cake so granularly (i.e. by market segment) we should try to boil down key principles and then offer real-language explanations for each principle’s application in particular business environments instead. This division of the commons is a topic that researchers appreciate and struggle with.

Analysis: ipoque, DPI, and Network Neutrality

/ Christopher Parsons / 10 Comments

netneutralityrallyottawaGerman Deep Packet Inspection (DPI) manufacturer, ipoque, has produced a white paper titled “Deep Packet Inspection: Technology, Applications & Network Neutrality.” In it, the company distinguishes between DPI as a technology and possible applications of the technology in a social environment. After this discussion they provide a differentiated ‘tiering’ of various bandwidth management impacts on network neutrality. In this post I offer a summary and comment of the white paper, and ultimately wonder whether or not there is an effective theoretical model, grounded in empirical study, to frame or characterize network neutrality advocates.

The first thing that ipoque does is try and deflate the typically heard ‘DPI analysis = opening a sealed envelop’ analogy, and argue that it is better to see packets as postcards, where DPI analysis involves looking for particular keywords or characters. In this analysis, because the technology cannot know of the meaning of what is being searched for, the DPI appliances cannot be said to violate one’s privacy given the technology’s lack of contextual awareness. I’ve made a similar kind of argument, that contextual meaning escapes DPI appliances (though along different lines) in a paper that I presented earlier this year titled “Moving Across the Internet: Code-Bodies, Code-Corpses, and Network Architecture,” though I think that its important to recognize a difference between a machine understandingsomething itself versus flagging particular words and symbols for a human operator to review. Ubiquitous, “non-aware,” machine surveillance can have very real effects where a human is alerted to communications – its something of a misnomer to say that privacy isn’t infringed simply because the machine doesn’t know what it’s doing. We ban and regulate all kinds of technologies because of what they can be used for rather than because the technology itself is inherently bad (e.g. wiretaps).

The Geek, Restraining Orders, and Theories of Privacy

/ Christopher Parsons / 5 Comments

restrainingorderI’ve been reading some work on privacy and social networks recently, and this combined with Ratliff’s “Gone Forever: What Does It Really Take to Disappear” has led me to think about whether a geek with a website that is clearly their own (e.g. Christopher-Parsons.com) should reasonably expect restraining laws to extend to digital spaces. I’m not really talking at the level of law necessarily, but at a level of normativity: ought a restraining order limit a person from ‘following’ me online as it does from being near me in the physical world?

Restraining orders are commonly issued to prevent recurrences of abuse (physical or verbal) and stalking. While most people who have a website are unable to track who is visiting their webspace, what happens when you compulsively check your server logs (as many good geeks do) and can roughly correlate traffic to particular geo-locations. As a loose example, let’s say that you were in a small town, ‘gained’ an estranged spouse, and then notice that there are regular hits to your website from that small town after you’ve been away from it for years. Let’s go further and say that you have few/no friends in that town, and that you do have a restraining order that is meant to prevent your ex-spouse from being anywhere near you. Does surfing to your online presence (we’ll assume, for this posting, that they aren’t commenting or engaging with the site) normatively constitute a breach of an order?

Context, Privacy, and (Attempted) Blogger Anonymity

/ Christopher Parsons / 5 Comments

bloggingtimelineWhile it’s fine and good to leave a comment where neither you nor an anonymous blogger know one another, what happens when you do know the anonymous blogger and it’s clear that they want to remain anonymous? This post tries to engage with this question, and focuses on the challenges that I experience when I want to post on an ‘anonymous’ blog where I know who is doing the blogging – it attends to the contextual privacy questions that race through my head before I post. As part  of this, I want to think through how a set of norms might be established to address my own questions/worries, and means of communicating this with visitors.

I’ve been blogging in various forms for a long time now – about a decade (!) – and in every blog I’ve ever had I use my name. This has been done, in part, because when I write under my name I’m far more accountable than when I write under an alias (or, at least I think this is the case). This said, I recognize that my stance to is slightly different than that of many bloggers out there – many avoid closely associating their published content with their names, and often for exceedingly good reasons. Sometimes a blogger wants to just vent, and doesn’t want to deal with related social challenges that arise as people know that Tommy is angry. Others do so for personal safety reasons (angry/dangerous ex-spouses), some for career reasons (not permitted to blog/worried about effects of blogging for future job prospects), some to avoid ‘-ist’ related comments (sexist, racist, ageist, etc.).
