Records showing the full website addresses you have visited — for instance, www.gchq.gov.uk/what_we_do — are treated as content. But the first part of an address you have visited — for instance, www.gchq.gov.uk — is treated as metadata.
In isolation, a single metadata record of a phone call, email, or website visit may not reveal much about a person’s private life, according to Ethan Zuckerman, director of Massachusetts Institute of Technology’s Center for Civic Media.
But if accumulated and analyzed over a period of weeks or months, these details would be “extremely personal,” he told The Intercept, because they could reveal a person’s movements, habits, religious beliefs, political views, relationships, and even sexual preferences.
For Zuckerman, who has studied the social and political ramifications of surveillance, the most concerning aspect of large-scale government data collection is that it can be “corrosive towards democracy” — leading to a chilling effect on freedom of expression and communication.
“Once we know there’s a reasonable chance that we are being watched in one fashion or another it’s hard for that not to have a ‘panopticon effect,’” he said, “where we think and behave differently based on the assumption that people may be watching and paying attention to what we are doing.”
Gary Edwards on 10 Sep 13"Startup Numecent has come out of stealth mode today with some of the most impressive enterprise technology we've seen in a decade. Plus the company is interesting for other reasons, like its business model and its founder. Numecent offers something it calls "cloud paging" and, if successful, it could be a game-changer for enterprise software, video gaming, and smartphone apps. Red Hat thinks so. It has already partnered with the company to help it offer Windows software to Linux users. "Cloud paging" instantly "cloudifies" any software, even an operating system like Windows itself, says founder and CEO Osman Kent. It lets any software, with no modification, be delivered from the cloud and run as fast or faster than if the app was on your desktop. Lots of so-called "desktop virtualization" services work fast. But cloud-paging can even operate the cloud software if the PC gets disconnected from the network or Internet. It can also turn a smartphone into a server. That means a bunch of devices like tablets can run the software -- like a game -- off of the smartphone. Imagine showing up to a party and letting all your friends play the latest version of Halo from your phone. That's crazy cool. Cloudpaging can do all this because it doesn't use "pixel-streaming" technology like other virtualization tech. Instead it temporarily downloads bits of the application itself (instructions) and runs them on the device. It can almost magically predict which parts of the app the user will need, and downloads only those parts. For business owners, that's not even the best part. It also helps enterprises sidestep extra licensing fees associated with the cloud. For instance, Microsoft licenses its software by the device, not by the user, and, in many cases, charges a "Virtual Desktop Access" fee for each device using a virtual version of Windows. (For a bit of light reading, check out the Microsoft virtual desktop licensing white paper: PDF) Cloudpaging has what Kent calls "f
