    Verizon's got a couple of loose ends to tie up. It's nothing important, you understand, just a tweak to its privacy policy that will allow the carrier to monitor your physical movements and browsing activities. It actually did much the same thing back in 2007 to monitor phone calls. The aim, of course, is to tailor ads to your interests, while also gathering information about your habits that it can sell on to others in the form of "business and marketing reports." Oh, one more thing: VZW promises not to share any information about you "personally" and it also gives you the option to opt out. (Opt out.)

  • NEC tech detects illegal video uploads in seconds, MPAA swoons

    Surely by now you've come across something on YouTube that was flagged for copyright infringement, a process that's surely powered by massive teams of elves and other mystical creatures who watch each and every video uploaded to the site. NEC is looking to put them all out of work with a system that, with just 60 frames worth of video (about two seconds, typically) can identify copyrighted video with 96 percent accuracy and a false alarm rate of one in 200,000 -- even if it was copied from digital to analog or had captions added. This process is now part of the MPEG-7 Video signature tool, apparently the international standard, and works by creating signatures for copyrighted video that are just 76 bytes per frame. That's small enough for a desktop with a single core, 3GHz processor to churn through 1,000 hours of questionable video in one second, looking for matches all the while. Unless you freelance for the MPAA this isn't software you'll be running, but if you're a fan of the torrents there's a good chance that someone you know very indirectly will be.
