NSA mines Facebook for connections, Americans' profiles

NEW YORK (CNN) -- In addition to phone records and email logs, the National Security Agency uses Facebook and other social media profiles to create maps of social connections -- including those of American citizens.The revelation was disclosed by the New York Times on Sunday, using documents provided to the newspaper by former government contractor Edward Snowden."We assume as Americans that if somebody in the government is looking at your information, it's because they have a reason, because you're suspected of a crime," Karen Greenberg, director of the Center on National Security at Fordham Law School, told CNN.But the documents do not specify how many Americans' social connections have been analyzed, or whether any have been implicated in wrongdoing.Change in policyThe surveillance began after a policy change in November 2010.Prior to then, the "chaining" of a foreign person's contacts had to stop when it reached an American citizen or legal resident.The policy change was intended to help the NSA "discover and track" connections from a foreign intelligence subject to an American citizen, the leaked documents show.It allows NSA analysts to use social media, geo-location information, insurance and tax records, plus other public and private sources to enhance their analysis of phone and email records, The Times reported Sunday.The "metadata" from phone and email records in the database include details such as who a person called or e-mailed.A PowerPoint slide provided to the newspaper by Snowden shows how analysts use software to create diagrams of where a person was at certain times, their traveling companions, their social networks and email correspondents.Defending the practicePresident Barack Obama has ordered a review of NSA's data collection practices because of Snowden's leaks.

U.S. court says 'liking' something on Facebook is free speech

(CNN) -- A U.S. court of appeals gave Facebook a thumbs up on Wednesday when it ruled that "likes" on the social network are protected as free speech under the Constitution.In 2009, six employees at the Hampton Sheriff's Office in Virginia lost their jobs after expressing support for their boss' opponent in an upcoming election for sheriff, some by liking and commenting on the opponent's Facebook page.U.S. Circuit Judge William Traxler found that "liking" something on the social network was the "Internet equivalent of displaying a political sign in one's front yard," an act the Supreme Court has already ruled as protected speech.The decision from the 4th U.S. Circuit Court of Appeals in Richmond, Virginia, was a reversal of an earlier ruling on the case, in which District Judge Raymond Jackson said liking a Facebook page was "insufficient speech to merit constitutional protection."Other courts have ruled that posts on the social network are protected as free speech, but Jackson differentiated between making full statements and just clicking a button to like something.Two of the employees, Deputy Daniel Carter and Robert McCoy, claimed they were fired by Sheriff B.J. Roberts specifically for liking a Facebook profile for Roberts' opponent, Jim Adams.

New Facebook flap: Your face in some product's ad

NEW YORK (CNNMoney) -- A new Facebook policy that allows your picture to be used in a product or store's ad without your knowledge has privacy groups united in opposition.Executives from six public interest groups on Wednesday signed a joint letter to the Federal Trade Commission asking that the agency act to stop Facebook's new privacy and data use policies."Facebook users who reasonably believed that their images and content would not be used for commercial purposes without their consent will now find their pictures showing up on the pages of their friends endorsing the products of Facebook's advertisers," said the letter. "Remarkably, their images could even be used by Facebook to endorse products that the user does not like or even use."Facebook's new proposed policy was announced last week in the wake of a $20 million settlement of a class action suit about its privacy rules.The new rules "while not incorporating all features that some of the objectors might prefer, has significant value and provides benefits that likely could not be obtained outside the context of a negotiated settlement," wrote Judge Richard Seeborg in his order approving the court settlement.But the public interest groups argue that the settlement, and the changes that Facebook agreed to, do not go far enough, particularly when it comes to protecting the rights of minors who use the site."It requires 'Alice in Wonderland' logic to see this as anything but a major setback for the privacy rights of Facebook users," said the group's letter.The posting on Facebook's site by Erin Egan, its Chief Privacy Officer, says the proposed changes in its rules were done to help its users understand how the social media site uses their information.
