In the best tradition of educators who manage to be both entertaining and enlightening, Duke sociology professor Kieran Healy has posted “Using Metadata to Find Paul Revere”—a fascinating demonstration of just how revealing metadata can be when subject to certain quite simple but powerful number-crunching techniques. Using simple information about 260 colonists in the years before the American Revolution (what organizations they belong to), he shows step by step how the lowest analyst at the “Royal Security Agency” could use that data to build powerful insights into what might be going on among the rebellious colonists.
The scariest thing about this is just how small and simple the starting data set is. Healy concludes:
I must ask you to imagine what might be possible if we were but able to collect information on very many more people, and also synthesize information from different kinds of ties between people! For the simple methods I have described are quite generalizable in these ways, and their capability only becomes more apparent as the size and scope of the information they are given increases. We would not need to know what was being whispered between individuals, only that they were connected in various ways. The analytical engine would do the rest!
In other words, this demonstration has just show us a hint of what an organization like the NSA can probably do with metadata.
More evidence that (as we have argued at greater length elsewhere) those downplaying the intrusiveness of metadata are way behind the times.

The Foreign Intelligence Surveillance Court order released yesterday by The Guardian reveals that the U.S. government is regularly tracking the phone calls of potentially millions of Americans.
ACLU attorneys have been monitoring the U.S. government’s use of the Patriot Act for years, and this document confirms our biggest fears. Have a look at the notes we’ve made on the court order to see how we understand what it says about the powers the government claims.

In response to an ACLU Freedom of Information Act request, the Department of Homeland Security has at long last released its December 2011 Civil Rights/Civil Liberties Impact Assessment of its policy of conducting suspicionless searches of electronic devices at the border. Because of the sensitive, personal nature of the records we all carry with us on our laptops and phones, both the First and Fourth Amendments prohibit the government from searching these devices at the border, absent reasonable suspicion that a search will turn up evidence of wrongdoing.

Court rulings unsealed last week in Washington show for the first time a behind-the-scenes legal battle over when the government should have to tell you that it's tracking your location and reading your email. These documents—which came to light only as the public learned more about the government's controversial investigation of Fox News journalist James Rosen—reveal significant new details about the government's obligation to provide notice, after the fact, when it obtains geolocation data or obtains stored email messages. Indeed, the court orders bring to light a striking contrast: federal prosecutors in Washington routinely provide notice to individuals they track using cell-phone geolocation data, even if that notice is delayed, yet the government strenuously resists giving any notice to individuals when searching and reading their emails.

Last week we learned that the Department of Justice, in an unprecedented intrusion on the work of journalists, had obtained records for twenty telephone numbers belonging to the Associated Press or its reporters, spanning April and May 2012. The telephone records obtained do not include the content of phone calls, but they likely reveal the phone number of each and every caller on those lines for a period of weeks and, therefore, the identity of scores of confidential media sources.
The seizure of these records came to light only because the government has a special set of guidelines that require it to notify any media organization of a subpoena for its records within (at most) 90 days. The AP appears to have learned of the seizure of its phone records, albeit after the fact, only because of this special policy.
The notice given to the AP has generated a healthy debate over the limits on the government’s authority to acquire our telephone and internet records. But what if you aren’t a media organization and, therefore, do not benefit from the special government policy entitling you to notice when the government obtains your telephone or internet records? What information can the government get about you, and is it even required to tell you when it does so?

An important Congressional subcommittee held a hearing today on domestic drone use. Members and witnesses didn't just rehash familiar concerns; they dug deeper to explore how advanced surveillance technology has become, and the real dangers of the surveillance society that it creates.
The hearing, held by the House Judiciary Committee's Subcommittee on Crime, Terrorism, Homeland Security, and Investigations began with testimony from the ACLU and three representatives from the academic community. (You can read the ACLU's complete testimony here.) While they had different ideas of what government regulation of domestic drone use should look like, the witnesses all stressed the increasing sophistication of drones, which will lead to levels of surveillance previously unseen. The testimony drove home the fact that drones are getting smaller, cheaper, and their use is about to blow up.

On May 8, the ACLU released a slew of government documents obtained from the FBI, U.S. Attorneys' offices around the country, and the Justice Department's Criminal Division concerning the government's access to the contents of private electronic communications. The mediahasseizedupon one of those documents, an undated memo titled, "Guidance for the Minimization of Text Messages over Dual-Function Cellular Telephones." This memo may show that the Criminal Division is doing nothing at all to avoid reading our text messages; it may show great procedures in place to safeguard the privacy our text messages; or, likely, it may have nothing to do with either of those predictions. The public does not know because the Justice Department put a large black box over every word following the header of the 15-page memo.
