How much extra will you have to pay for the privilege of being spied on?

UK ISPs have warned MPs that the costs of implementing the Investigatory Powers Bill (aka the Snooper's Charter) will be much greater than the £175 million the UK government has allotted for the task, and that broadband bills will need to rise as a result. Representatives from ISPs and software companies told the House of Commons Science and Technology Committee that the legislation greatly underestimates the "sheer quantity" of data generated by Internet users these days. They also pointed out that distinguishing content from metadata is a far harder task than the government seems to assume. Matthew Hare, the chief executive of ISP Gigaclear, said with "a typical 1 gigabit connection to someone's home, over 50 terabytes of data per year [are] passing over it. If you say that a proportion of that is going to be the communications data—the record of who you communicate with, when you communicate or what you communicate—there would be the most massive and enormous amount of data that in future an access provider would be expected to keep. The indiscriminate collection of mass data across effectively every user of the Internet in this country is going to have a massive cost."

Moreover, the larger the cache of stored data, the more worthwhile it will be for criminals and state-backed actors to gain access and download that highly-revealing personal information for fraud and blackmail. John Shaw, the vice president of product management at British security firm Sophos, told the MPs: "There would be a huge amount of very sensitive personal data that could be used by bad guys.

The Intercept published an expose on the NSA's XKeyscore program. Along with information on the breadth and scale of the NSA's metadata collection, The Intercept revealed how the NSA relies on unencrypted cookie data to identify users. As The Intercept says: "The NSA’s ability to piggyback off of private companies’ tracking of their own users is a vital instrument that allows the agency to trace the data it collects to individual users. It makes no difference if visitors switch to public Wi-Fi networks or connect to VPNs to change their IP addresses: the tracking cookie will follow them around as long as they are using the same web browser and fail to clear their cookies." The NSA slides released by The Intercept give detailed guides to understanding the data transmitted by these cookies, as well as how to find unique machine identifiers that analysts can use to differentiate between multiple machines using the same IP address. We've written before about how spy agencies piggyback on social media account data to find Internet users' names or other identifying info, and these slides drive home the point that HTTP cookies leave users vulnerable to government surveillance, since any intermediary (or spy agency) can read the sensitive data they contain.

Worse yet, most of the time these identifying cookies come from third-party sources on webpages, and users have no meaningful way to opt out of receiving them (short of blocking all third party cookies) since advertisers (the main server of these types of cookies) refuse to honor the Do Not Track header.  Browser makers could help address this sort of non-consensual tracking by both advertisers and the NSA with some simple technical changes—changes that have been shown to reduce the number of third party cookies received by 67%. So far, though, they've been unwilling to build privacy protecting features in by default. Until they do, the best way for users to protect themselves is by installing a privacy protecting app like Privacy Badger, which is designed to block these types of uniquely identifying tracking cookies, or HTTPS Everywhere to block the transmission of HTTP cookies.

In the UK earlier this month, human rights groups Liberty and Privacy International were cheered by a tribunal decision that declared GCHQ’s access to NSA spies’ data illegal. Though it was a hollow victory, as the tribunal also declared all current activities, including all those blanket surveillance projects much derided by free speech activists, entirely legal. The practices previously broke the law because the public was unaware of what safeguards were in place for the UK’s access to data from NSA programs like Prism; as soon as Snowden blew everything wide open the snoops had to explain themselves, and that was enough for the tribunal to confirm the legality of GCHQ’s operations. But the case has had one significant effect: anyone can now figure out if their data was illegally shared by the agencies. Privacy International has set up a simple webpage that anyone in the world can sign up to. You can visit the page here.

Once the UK Investigatory Powers Tribunal has determined whom was affected, it has to inform them. Though participants should find out whether their data were unlawfully obtained by GCHQ from the millions of private communications hoovered up by the NSA up until December 2014, it won’t be anytime soon. Privacy International warned in its FAQs: “Count on it being many months, and likely years before this action is completed.” And somewhat ironically Privacy International has to collect participant’s information, including their name and email address, to supply the service. They may ask for more information from willing participants once the group has determined if more is required from the IPT. Anyone who wants to submit directly to the tribunal can do so here.
