The Role of Digital Surveillance in Stopping the Past’s Rebirth
Most of the music that I listen to clearly borrows from the past, takes technologies of the present, and creates the music of the future again. To be clear, I’m not suggesting that the electronic beats that I listen to … Continue reading
Announcement: Working Paper on DPI Now Available
The abstract is below: Internet Service Providers (ISPs) are responsible for transmitting and delivering their customers’ data requests, ranging from requests for data from websites, to that from file-sharing applications, to that from participants in Voice over Internet Protocol (VoIP) chat sessions. … After discussing the potency of contemporary packet inspection devices, in relation to their earlier packet inspection predecessors, and their potential uses in improving network operators’ network management systems, I argue that they should be identified as surveillance technologies that can potentially be incredibly invasive. Drawing on Canadian examples, I argue that Canadian ISPs are using DPI technologies to implicitly ‘teach’ their customers norms about what are ‘inappropriate’ data transfer programs, and the appropriate levels of ISP manipulation of consumer data traffic.

Update: Bell Users’ Average Bandwidth Use
( Source ) Just a quick note about an interesting tidbit that was passed out by the Bell rep who gave a presentation on DPI today: A few years ago (no precise dates given) users were consuming, on average, 1GB of traffic; this has risen tenfold since that date. As Bell has repeatedly stated in CRTC submissions, they are not caching personally identifiable information as packets course through their DPI equipment, but still maintain that they are looking into the application layer of packets, but not the ‘content’ of the packet. … In the next day or so, I’ll be putting up more thoughts and facts that emerged through the 10th annual security and privacy conference, ” Life in a Digital Fishbowl “.
