Update: Mobiles and Your Identity

/ Christopher Parsons

Last year I authored a post entitled “Mobiles and Your Identity“, where I attempted to unpack some of the privacy and surveillance concerns that are associated with smart phones, such as RIM’s Blackberry and Apple’s iPhone. In particular, I focused on the dangers that were associated with the theft of a mobile device – vast swathes of both your own personal data, as well as the personal information of your colleagues and friends, can be put at risk by failing to protect your device with passwords, kill switches, and so forth.

Mark Nestmann, over at “Preserving Your Privacy and More” has a couple posts discussing the risks that smart phones pose if a government authority arrests you (in the US). He notes that, in a recent case in Kansas, police examined a suspect’s mobile phone data to collect call records. When the case was brought to the Supreme Court, the Court found that since the smart phone’s records were held in a ‘container’ (i.e. the phone itself) that the police were within their rights to search the phone records. Mark notes that this ruling does not apply to all US states – several have more sensitive privacy laws – but leaves us with the warning that because laws of analogue search are being applied to digital devices that it is best to limit the data stored on smart phones (and mobile digital devices in general).

Technology: CBC’s Search Engine and Traffic Shaping

The CBC’s Jesse Brown has a nice piece that tries to respond to the question, “Is Throttling Necessary?” I won’t spoil the answer (or possible lack of an answer), but I will note that Jesse incorporated a few pieces of information that I’ve posted about here. If you’re not already subscribed to his Search Engine podcast, you should – it’s amongst the best Canadian tech journalism (that is accessible to non-tech people).

P2P and Complicity in Filesharing

/ Christopher Parsons

I think about peer to peer (P2P) filesharing on a reasonably regular basis, for a variety of reasons (digital surveillance, copyright analysis and infringement, legal cases, value in efficiently mobilizing data, etc.). Something that always nags at me is the defense that P2P websites offer when they are sued by groups like the Recording Industry Association of America (RIAA). The defense goes something like this:

“We, the torrent website, are just an search engine. We don’t actually host the infringing files, we are just responsible for directing people to them. We’re no more guilty of copyright infringement than Google, Yahoo!, or Microsoft are.”

Let’s set aside the fact that Google has been sued for infringing on copyright on the basis that it scrapes information from other websites, and instead turn our attention to the difference between what are termed ‘public’ and ‘private’ trackers. ‘Public’ trackers are available to anyone with a web connection and a torrent program. These sites do not require users to upload a certain amount of data to access the website – they are public, insofar as there are few/no requirements placed on users to access the torrent search engine and associated index. Registration is rarely required. Good examples at thepiratebay.org, and mininova.org. ‘Private’ trackers require users to sign up and log into the website before they can access the search engine and associated index of .torrent files. Moreover, private trackers usually require users to maintain a particular sharing ration – they must upload a certain amount of data that equals or exceeds the amount of data that they download. Failure to maintain the correct share ratio results in users being kicked off the site – they can no longer log into it and access the engine and index.

Review: Access Denied

/ Christopher Parsons

The OpenNet Initiative’s (ONI) mission is to “identify and document Internet filtering and surveillance, and to promote and inform wider public dialogs about such practices.” Access Denied: The Practice and Policy of Global Internet Filtering is one of their texts that effectively draws together years of their research, and presents it in an accessible and useful manner for researchers, activists, and individuals who are simply interested in how the Internet is shaped by state governments.

The text is separated into two broad parts – the first is a series of essays that situate the data that has been collected into a quickly accessible framework. The authors of each essay manage to retain a reasonable level of technical acumen, even when presenting their findings and the techniques of filtering to a presumably non-technical audience. It should be noted that the data collected includes up to 2007 – if you’re reading the text in the hopes that the authors are going to directly address filtering technologies that have recently been in the new, such as Deep Packet Inspection, you’re going to be a disappointed (though they do allude to Deep Packet technologies, without explicitly focusing on it, in a few areas). Throughout the text there are references to human rights and, while I’m personally a proponent of them, I wish that the authors had endeavored to lay out some more of the complexities of human rights discourse – while they don’t present these rights as unproblematic, I felt that more depth would have been rewarding both for their analysis, and for the benefit of the reader. This having been said, I can’t begrudge the authors of the essays for drawing on human rights at various points in their respective pieces – doing so fits perfectly within ONI’s mandate, and their arguments surrounding the use of human rights are sound.

Ownership of Public Clouds

/ Christopher Parsons

I’ve recently been chewing through BlueMountainLab’s podcasts on Cloud Computing. I’ll be honest – I’m a skeptic when it comes to cloud computing, but I’m developing a better understanding of it after listening to ‘casts on this topic for about 2 hours (maybe I’m just been brainwashed?). If you’re not immediately familiar with what this term means, check out the below video – you’ll see some of the biggest and brightest minds in digital technologies explain in simple terms what ‘cloud computing’ is.


Unless you’ve been living under a rock, or away from a digital connection, for the past couple of years you’ve likely experienced cloud computing. Have you hopped into Google docs, Zimbra, or any other environment where you perform standard tasks in a web-based environment? If so, you’ve been ‘in the cloud’. What we’re seeing is a shift away from centrally owned company infrastructure toward infrastructure that is owned and operated by another company. To picture it, rather than host your own mail servers, you shift your corporation over to Google Apps, and at the same time can take advantage of the word processing, chat, and page creation features that accompany the Google solution. Should you need to increase storage, or alter your current feature set, you can have it set up in a few hours – this contrasts with spending corporate resources acquiring a solution, installing it, educating your users, etc. By outsourcing high-cost, high-time-sink operations you can realign your IT staff so that they can focus on corporate issues; designing unique solutions for unique problems, focusing their skill sets in more cost-effective areas, etc.
