"As the federal government readies the third iteration of Einstein, privacy concerns over the intrusion detection system were voiced at a Senate hearing on Tuesday. Philip Reitinger, Department of Homeland Security deputy undersecretary for the National Protection and Programs Directorate, told the Senate Committee on the Judiciary's Subcommittee on Terrorism and Homeland Security that DHS envisions deploying Einstein 3 as an intrusion prevention system. Einstein 1 monitors network flow and Einstein 2 detects system intrusions. "This more robust version of Einstein would provide the federal government with an improved early warning and an enhanced situational awareness; the ability to automatically detect malicious activity; and the capability to prevent malicious intrusions before harm is done," Reitinger said. But Gregory Nojeim, senior counsel and director of Project Freedom, Security and Technology at the Center for Democracy and Technology, cited press accounts that Einstein 3 would rely on pre-defined signatures of malicious code that might contain personally identified information, and threaten the privacy of law-abiding citizens. "While Einstein 2 merely detected and reported malicious code, Einstein 3 is to have the capability of intercepting threatening Internet traffic before it reaches a government system, raising additional concerns," Nojeim testified. Einstein 3 reportedly could operate within the networks of private telecommunications companies, and Nojeim wondered if the technology could analyze private-to-private communications. "If Einstein were to analyze private-to-private communications, that would likely be an interception under the electronic surveillance laws, requiring a court order," he said. "

"Want to know how much phone companies and internet service providers charge to funnel your private communications or records to U.S. law enforcement and spy agencies? That's the question muckraker and Indiana University graduate student Christopher Soghoian asked all agencies within the Department of Justice, under a Freedom of Information Act (FOIA) request filed a few months ago. But before the agencies could provide the data, Verizon and Yahoo intervened and filed an objection on grounds that, among other things, they would be ridiculed and publicly shamed were their surveillance price sheets made public. Yahoo writes in its 12-page objection letter (.pdf), that if its pricing information were disclosed to Soghoian, he would use it "to 'shame' Yahoo! and other companies - and to 'shock' their customers.""

"The Electronic Frontier Foundation said it sued the Justice Department and other U.S. agencies to get information about their policies for using social networks including Facebook and Twitter in investigations, data collection and surveillance. The civil rights group said in a complaint filed yesterday in federal court in San Francisco that the government has used social-networking sites in conducting investigations and hasn't clarified the scope of that use or whether there are any restrictions or oversight to prevent abuses. The EFF said in its complaint that it is seeking the information to "help inform Congress and the public about the effect of such uses and purposes on citizens' privacy rights and associated legal protections." It cited news articles that reported police searching Facebook photos for evidence of underage drinking and an FBI search of an individual's home after the person sent messages on Twitter during the G-20 Summit notifying protesters of police movements. Facebook, based in Palo Alto, California, is the world's largest social networking site with more than 300 million users who post photos, messages and other information on their own free Facebook pages. Twitter, based in San Francisco, is a free Web service with 58 million users that lets people send 140- character messages, called "tweets," to multiple followers. EFF, also based in San Francisco, filed Freedom of Information Act requests with federal agencies in October. None of the agencies had completed processing the requests by the applicable 20-day deadline, according to the complaint. The lawsuit seeks a court order for the government to process the requests and produce documents."

President Barack Obama's plan to overhaul U.S. infrastructure includes constructing a nationwide "smart grid" that promises to help address many of our current energy challenges. The smart grid plan offers the hope that it "will save us money, protect our power sources from blackout or attack, and deliver clean, alternative forms of energy to every corner of our nation." While these are noble societal goals, smart grid technologies and systems as envisioned also raise concerns about individual privacy rights. Part of what makes the smart grid "smart" is its ability to know a lot about the energy-consuming devices in our homes and to monitor activity for those devices to help determine when power should be used or limited. Such knowledge is useful in regulating power consumption to use energy more efficiently. In addition to reaching into homes to regulate devices, information about usage and activities could be extracted from homes. Home energy consumption patterns could be gathered and analyzed on a room-by-room and device-by-device basis to determine which devices are used and at what time of day. Although this sort of information may not be considered terribly invasive for some, for others anything that violates the sanctity of "home" may cause tremendous concern.
