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.

On Tuesday, the European court of justice, Europe’s supreme court, lobbed a grenade into the cosy, quasi-monopolistic world of the giant American internet companies. It did so by declaring invalid a decision made by the European commission in 2000 that US companies complying with its “safe harbour privacy principles” would be allowed to transfer personal data from the EU to the US. This judgment may not strike you as a big deal. You may also think that it has nothing to do with you. Wrong on both counts, but to see why, some background might be useful. The key thing to understand is that European and American views about the protection of personal data are radically different. We Europeans are very hot on it, whereas our American friends are – how shall I put it? – more relaxed.

Given that personal data constitutes the fuel on which internet companies such as Google and Facebook run, this meant that their exponential growth in the US market was greatly facilitated by that country’s tolerant data-protection laws. Once these companies embarked on global expansion, however, things got stickier. It was clear that the exploitation of personal data that is the core business of these outfits would be more difficult in Europe, especially given that their cloud-computing architectures involved constantly shuttling their users’ data between server farms in different parts of the world. Since Europe is a big market and millions of its citizens wished to use Facebook et al, the European commission obligingly came up with the “safe harbour” idea, which allowed companies complying with its seven principles to process the personal data of European citizens. The circle having been thus neatly squared, Facebook and friends continued merrily on their progress towards world domination. But then in the summer of 2013, Edward Snowden broke cover and revealed what really goes on in the mysterious world of cloud computing. At which point, an Austrian Facebook user, one Maximilian Schrems, realising that some or all of the data he had entrusted to Facebook was being transferred from its Irish subsidiary to servers in the United States, lodged a complaint with the Irish data protection commissioner. Schrems argued that, in the light of the Snowden revelations, the law and practice of the United States did not offer sufficient protection against surveillance of the data transferred to that country by the government.

The Irish data commissioner rejected the complaint on the grounds that the European commission’s safe harbour decision meant that the US ensured an adequate level of protection of Schrems’s personal data. Schrems disagreed, the case went to the Irish high court and thence to the European court of justice. On Tuesday, the court decided that the safe harbour agreement was invalid. At which point the balloon went up. “This is,” writes Professor Lorna Woods, an expert on these matters, “a judgment with very far-reaching implications, not just for governments but for companies the business model of which is based on data flows. It reiterates the significance of data protection as a human right and underlines that protection must be at a high level.”

In a Chicago court, several Facebook users filed a class-action lawsuit against the social media giant for allegedly violating its users’ privacy rights to acquire the largest privately held stash of biometric face-recognition data in the world. The court documents reveal claims that “Facebook began violating the Illinois Biometric Information Privacy Act (IBIPA) of 2008 in 2010, in a purported attempt to make the process of tagging friends easier.”

This was accomplished through the “tag suggestions” feature provided by Facebook which “scans all pictures uploaded by users and identifies any Facebook friends they may want to tag.” The Facebook users maintain that this feature is a “form of data mining [that] violates user’s privacy”. One plaintiff said this is a “brazen disregard for its users’ privacy rights,” through which Facebook has “secretly amassed the world’s largest privately held database of consumer biometrics data.” Because “Facebook actively conceals” their protocol using “faceprint databases” to identify Facebook users in photos, and “doesn’t disclose its wholesale biometrics data collection practices in its privacy policies, nor does it even ask users to acknowledge them.”

This would be a violation of the IBIPA which states it is “unlawful to collect biometric data without written notice to the subject stating the purpose and length of the data collection, and without obtaining the subject’s written release.” Because all users are automatically part of the “faceprint’ facial recognition program, this is an illegal act in the state of Illinois, according to the complaint. Jay Edelson, attorney for the plaintiffs, asserts the opt-out ability to prevent other Facebook users from tagging them in photos is “insufficient”.

Activists worried about online privacy are sending Congress a message with some old-school technology: They're sending faxes -- more than 6.2 million, they claim -- to express opposition to the Cybersecurity Information Sharing Act (CISA).Why faxes? "Congress is stuck in 1984 and doesn't understand modern technology," according to the campaign Fax Big Brother. The week-long campaign was organized by the nonpartisan Electronic Frontier Foundation, the group Access and Fight for the Future, the activist group behind the major Internet protests that helped derail a pair of anti-piracy bills in 2012. It also has the backing of a dozen groups like the ACLU, the American Library Association, National Association of Criminal Defense Lawyers and others.

CISA aims to facilitate information sharing regarding cyberthreats between the government and the private sector. The bill gained more attention following the massive hack in which the records of nearly 22 million people were stolen from government computers."The ability to easily and quickly share cyber attack information, along with ways to counter attacks, is a key method to stop them from happening in the first place," Sen. Dianne Feinstein, D-California, who helped introduce CISA, said in a statement after the hack. Senate leadership had planned to vote on CISA this week before leaving for its August recess. However, the bill may be sidelined for the time being as the Republican-led Senate puts precedent on a legislative effort to defund Planned Parenthood.Even as the bill was put on the backburner, the grassroots campaign to stop it gained steam. Fight for the Future started sending faxes to all 100 Senate offices on Monday, but the campaign really took off after it garnered attention on the website Reddit and on social media. The faxed messages are generated by Internet users who visit faxbigbrother.com or stopcyberspying.com -- or who simply send a message via Twitter with the hashtag #faxbigbrother. To send all those faxes, Fight for the Future set up a dedicated server and a dozen phone lines and modems they say are capable of sending tens of thousands of faxes a day.

Fight for the Future told CBS News that it has so many faxes queued up at this point, that it may take months for Senate offices to receive them all, though the group is working on scaling up its capability to send them faster. They're also limited by the speed at which Senate offices can receive them.
