Mobile Security and the Economics of Ignorance

Day 24/ Mon 17 Aug 09  Mobile penetration is extremely high in Canada. 78% of Canadian households had a mobile phone in 2010, in young households 50% exclusively have mobiles, and 33% of Canadians generally lack landlines. Given that mobile phones hold considerably more information than ‘dumb’ landlines and are widely dispersed it is important to consider their place in our civil communications landscape. More specifically, I think we must consider the privacy and security implications associated with contemporary mobile communications devices.

In this post I begin by outlining a series of smartphone-related privacy concerns, focusing specifically on location, association, and device storage issues. I then pivot to a recent – and widely reported – survey commissioned by Canada’s federal privacy commissioner’s office. I assert that the reporting inappropriately offloads security and privacy decisions to consumers who are poorly situated to – and technically unable to – protect their privacy or secure their mobile devices. I support this by pointing to intentional exploitations of users’ ignorance about how mobile applications interact with their device environments and residing data. While the federal survey may be a useful rhetorical tool I argue that it has limited practical use.

I conclude by asserting that privacy commissioners, and government regulators more generally, must focus their attention upon the Application Programming Interfaces (APIs) of smartphones. Only by focusing on APIs will we redress the economics of ignorance that are presently relied upon to exploit Canadians and cheat them out of their personal information.

Distinguishing Between Mobile Congestions

by Simon TunbridgeThere is an ongoing push to ‘better’ monetize the mobile marketplace. In this near-future market, wireless providers use DPI and other Quality of Service equipment to charge subscribers for each and every action they take online. The past few weeks have seen Sandvine and other vendors talk about this potential, and Rogers has begun testing the market to determine if mobile customers will pay for data prioritization. The prioritization of data is classified as a network neutrality issue proper, and one that demands careful consideration and examination.

In this post, I’m not talking about network neutrality. Instead, I’m going to talk about what supposedly drives prioritization schemes in Canada’s wireless marketplace: congestion. Consider this a repartee to the oft-touted position that ‘wireless is different’: ISPs assert that wireless is different than wireline for their own regulatory ends, but blur distinctions between the two when pitching ‘congestion management’ schemes to customers. In this post I suggest that the congestion faced by AT&T and other wireless providers has far less to do with data congestion than with signal congestion, and that carriers have to own responsibility for the latter.

iPhone Promiscuity

Photo credit: Steve KeysI’ve written a fair bit about mobile phones; they’re considerable conveniences that are accompanied by serious security, privacy, and technical deficiencies. Perhaps unsurprisingly, Apple’s iPhone has received a considerable amount of criticism in the press and by industry because of the Apple aura of producing ‘excellent’ products combined with the general popularity of their mobile device lines.

In this short post I want to revisit two issues I’ve previously written about: the volume of information that the iPhone emits when attached to WiFi networks and its contribution to carriers’ wireless network congestion. The first issue is meant to further document here, for my readers and my own projects, just how much information the iPhone makes available to third-parties. The second, however, reveals that a technical solution resolves the underlying cause of wireless congestion associated with Apple products. Thus, trapping customers into bucket-based data plans in response to congestion primarily served financial bottom lines instead of customers’ interests. This instance of leveraging an inefficient (economic) solution to a technical problem might, then, function as a good example of the difference between ‘reasonable technical management’ that is composed of technical and business goals versus the management of just the network infrastructure itself.

Do You Know Who Your iPhone’s Been Calling?

The-Apple-iPhone-3GS-gets-a-phoneAn increasing percentage of Western society is carrying a computer with them, everyday, that is enabled with geo-locative technology. We call them smartphones, and they’re cherished pieces of technology. While people are (sub)consciously aware of this love-towards-technology, they’re less aware of how these devices are compromising their privacy, and that’s the topic of this post.

Recent reports on the state of the iPhone operating system show us that the device’s APIs permit incredibly intrusive surveillance of personal behaviour and actions. I’ll be walking through those reports and then writing somewhat more broadly about the importance of understanding how APIs function if scrutiny of phones, social networks, and so forth is to be meaningful. Further, I’ll argue that privacy policies – while potentially useful for covering companies’ legal backends – are less helpful in actually educating end-users about a corporate privacy ethos. These policies, as a result, need to be written in a more accessible format, which may include a statement of privacy ethics that is baked into a three-stage privacy statement.

iOS devices, such as the iPhone, iPad, Apple TV 2.0, and iPod touch, have Unique Device Identifiers (UDIDs) that can be used to discretely track how customers use applications associated with the device. A recent technical report, written by Eric Smith of PSKL, has shed light into how developers can access a device UDID and correlate it with personally identifiable information. UDIDs are, in effect, serial numbers that are accessible by software. Many of the issues surrounding the UDID are arguably similar to those around the Pentium III’s serial codes (codes which raised the wrath of the privacy community and were quickly discontinued. Report on PIII privacy concerns is available here).
