Warspying in San Francisco

    The most fascinating part of this article to me - was the fact that it's NOT a violation of the wire tap act. It seems video isn't considered snooping. Talk about technology out pacing legislation. I wonder how long before we have one of those sites devoted to "hidden camera" porn? Oh, wait...

      It really has very little to do with legistlative sloth. The problem with legislating against this sort of thing is that its so tangled up in the issue of surveillance cameras. If you make videotaping an unknowing or unwilling person in a "public place" illegal, all surveillance cameras are then illegal. The problem is that drawing the line between useful surveillance and spying is so difficult. In this case, the transmissions being intercepted are not encrypted or even hidden. No attempt to keep them private has been made, and the owners/operators have no expectation of privacy. IANAL, but I can't see any way to extend the laws to cover this without being draconian. One other point: voyeur-type hidden cameras are usually beaten in civil court if the voyeur charges money for the video; it may be legal to spy on others without their permission, but selling it is usually a no-no.

      IANAL It wouldn't be illegal to receive this stuff no matter what the format. There is no reasonable expectation of privacy for transmissions in this band (it is not even intended for communications use). One really cool thing about this band is that no license is required to operate in the band and there are tons of perfectly good 500 to 1000 watt 2.4 MHz magnetrons with power supplies discarded every year -- free for the taking from dumpsters and the sides of residential streets. You can even buy a new 2.4 MHz magnetron with power supply for almost nothing.

    If they found some interesting finds, they left them out of the article. They found exactally what you would think they would find... cameras pointed at places in offices... not the hot lesbian orgy that you would hope for. Besides, isnt this a dupe?

  3. Broadcast privacy by nuggz · · Score: 5, Insightful

    When you broadcast something, you shouldn't expect it to remain private.

    If you want it to remain private, do something.
    Encrypt it, or don't send it out to everybody.

    Their latest expedition turned up some interesting finds.

    From the article:

    A few other cameras pop up, but nothing exciting -- until the financial district, where on the same block as the office cam, MWD's receiver picks up the very freeway camera that marked the start of the expedition. The camera is more than two miles away, while most wireless video cameras have trouble reaching the curb. The appearance of the signal so far from its source energizes the team. "That's definitely the catch of the night there," says MWD.

    So the "catch of the night" is a freeway camera. Woo-hoo! Oh well, at least now I know there are bigger dorks than myself.

    This sounds like a good plot starter for a political thriller.

    A college student goes out to look at wireless cameras and witnesses a murder, which is later ruled a suicide by the coroner's office in a massive political coverup. He has the murder recorded on the hard drive of his notebook computer, and shortly after he hands a CD he burned with an MPEG of the murder over to his uncle, a police detective, his uncle is then found dead, another "suicide." Then the kid realizes they'll be coming after him next, and a merry chase ensues.

    Has this already been done?

    "This kind of snooping doesn't violate federal wiretap laws, which generally protect audio communication, but not video, says Joseph Metcalf, an assistant professor at the University of Oregon law school. Moreover, the law keeps it legal to monitor radio transmissions that aren't encrypted or scrambled in any way, unless they're in a band specifically protected by statute, like analog cell phone signals. "If a communication is readily accessible to the general public, that communication is not protected by the federal Wiretap Act," says Metcalf. "

    Basically if you don't encrypt it it's your fault that someone else can read the signal.

    Nobody has a right to sniff like that.

    If you don't want people sniffing you, you shouldn't stink up the place.
    This is equivalent to communicating with your neighbours by shouting out of the window and then complaining that people are listening to what you say.
    As another poster pointed out, if you're broadcasting, you shouldn't expect privacy. If you're sold a wireless system as a private link, then the people to complain to are the sellers of the hardware for false advertising.

  9. Re:Maybe no lesbian orgies, but by swb · · Score: 5, Funny

    With a little detective work, MWD will eventually discover that the signal is a directional transmission from the camera to a local TV station that features the feed on its website and in its nightly newscast.

    So really the trick is to override their feed during the nightly news with more provocative content. It might be amusing to be real subtle about it, such as periodically putting footage from the wrong season or another time of day, CGI-ing the skyline (burning buildings, missing buildings, buildings that aren't really there, etc), using a different city skyline, etc. Just putting the goatse guy on would be a little less interesting.

    Ideally you'd have a reachable PC generating the video, with the ability to remotely switch between the real camera's feed and your feed to keep 'em guessing.

    All the more ironic that "The Conversation" was filmed in SF.

    Wardialing was coined after Matthew Broderick did that activity in the 1983 movie War Games. It was a little bit clever to mutate that into wardriving, but that took the prefix right up to the edge of Fonzie's ramp.
