Sensor Networks For Surveillance And Security 91

gpmap writes "Small Times has an article on the coming age of all-pervasive sensor networks that will feed information of all sorts to monitoring networks. Technology advances have generated intense interest in sensor networks: 'the magic words are surveillance and security.' The Palo Alto Research Center (PARC) hosted the second Information Processing in Sensor Networks workshop this week amid anticipation of significant funding grants from the National Science Foundation. Most believe miniaturization, whether through conventional methods, MEMS or nanotech, will drive the spread of sensor networks. But plenty of issues need working through, on the hardware, software and social fronts."

      Sorry, but you have really displayed complete ignorance of the topic in question. Of course, as soon as anything mildly related to privacy is posted here, immediate paranoia sets in. Sensor networks have a very broad range of applications, from monitoring temperatures in chemical engineering experiments to collecting ecosystem data. Enhanced security services are only one possible use for the technology, and a fairly mundane one at that.

      A common argument used here against legal acts such as the DMCA is that they unfairly blame the technology rather than those who misuse it. I don't see how your comment is any different. Personally I believe that sensor networks will provide many research opportunities and genuinely useful applications in the next few years. If organisations misuse one aspect of the technology for surveilance, then obviously those responsible should be held accountable. However, branding an entire field of research as being "unacceptable" is not particularly acceptable either.

            What part of "price" didn't you understand?

        It's true that every technology provides both foreseen and unforeseen uses, but in today's climate where people are willing to exchange privacy (anyone's) for security on the basis of only one foreign terrorist attack, the technology is an especially attractive target.

      Especially the rationalization that its ok to trade privacy for so-called security.

      If you think it is OK for airlines personel (or security personel) to search passengers and luggage for weapons and explosives, then you have already accepted that it is sometimes worthwhile to trade privacy for security.

      Here are a couple of ideas you might want to think about for a while.

      (1) Sometimes we have no reason to want or expect privacy, like when we hold a conversation with someone in a crowded elevator. Other times we do want and expect privacy. Before going off about intrusions on privacy, it would probably be a good idea to think about those times and places where privacy really matters. If we can trade the kind of privacy that does not matter for greater security then why not do so?

      (2) Privacy is not liberty. Sometimes it is a useful means to preserving liberty. The government can't stop you from doing something if they do not know you are doing it. But it is not the same thing as liberty. So while I would accept the claim that any trade of liberty for security is a sham, I would not accept the claim that any trade of privacy for security is a mistake.

      (3) Sometimes it is more a matter of trading privacy for liberty rather than trading privacy for security. There are, for example two ways to eliminate the threat of hijacked aircraft, and thus achieve security. You can limit privacy by searching passengers, or you can limit liberty by making comercial aviation illegal. Under the current system we gave up some privacy so that we could achieve a measure of security while also keeping our liberty (to travel etc). In cases like that I will take more liberty over more privacy every time.
      • "If you think it is OK for airlines personel (or security personel) to search passengers and luggage for weapons and explosives, then you have already accepted that it is sometimes worthwhile to trade privacy for security."

        You assume too much. If you don't go through airport security, then you have a travel time measured in days instead of hours to wherever you want to go. It's less trading liberty for security and more trading liberty for speed.
        • It's less trading liberty for security and more trading liberty for speed.

          It's not trading liberty at all because the searches by themselves do not introduce any new legal prohibitions on the actions that you are allowed to perform. It is a matter of trading privacy.

          For some people who travel it is partly a matter of trading privacy for speed, but obviously not for those who must either travel by air or not at all. For people on the ground it is strictly a matter of trading the privacy of others for thei

        I travel quite a bit all over the Europe. Ever since the latest airport security measures were put into place last year, I've given up flying. I have traded enough of my privacy and comfort for security. The airlines are not going to get any more of my money if I can just help it.

        Sigh. Excellent argument, except for the fact that searching passengers doesn't eliminate anything but the privacy of a few passengers. It does not eliminate the threat of hijacking. For example, you can strip search every passenger, but if I manage to bribe the caterers they can get weapons on board using the food carts.

        Or, for example, I can fabricate a

        • but if I manage to bribe the caterers they can get weapons on board using the food carts

          Which is so much easier than just walking on board with weapons - right? Don't you think there would be more hijackings if we did not have these security measures - or have there been none in the US since 9/11 because we ran out of bad guys?
          • Which is so much easier than just walking on board with weapons - right?

            The statement I am replying to had nothing to do with how hard some action was, it was a claim that searching passengers was one way to eliminate the threat of hijacking. Searching passengers does not eliminate anything, except the 4th amendment. In fact, if you care to recall, there were plenty of people who actually got onto airplanes carrying pointy things, even after being searched, and they weren't even trying to sneak things on

            • And no, I don't think there would have been more hijackings if Grandma hadn't been searched.

              Nevermind about searching Grandma. If you don't like searches you have to argue against the best case for having them, not the weakest. You have to argue for a situation where a group of men can walk straight on to a comercial airliner wearing body armor, with automatic weapons, explosives, and any other weapons they might find useful - because there are no searches at all.

      In my opinion, given the existence of surveillance networks the networks must be public access, to ensure a free society.

      ANY surveillance network which gives the watchers more information about the watched than the watched about the watchers leads to an imbalance of power. Thus, the watched must become the watchers, and have equal right of access to any surveillance network. Check out David Brin's book, "The Transparent Society: Will T

    In two words: Information leaks.

    It's somewhat like the before-mentioned leaky abstraction [slashdot.org] concept, but applied to information.

    It's going to get alot worse long before it gets better. Those who believe that true privacy is possible in the future are delusional.

    For a well though-out article on the subject, try reading this Wired article [wired.com] that

    Other unanswered questions involve how companies will filter the data generated by large networks of sensors...

    Leaving aside the other interesting bits of the article ("Videocams 1 sq.mm large? I'll crush them under my sandaled feet!"), this unanswered question is actually very, very important. For far too long both military* and non-military intelligence has focused far to much on gathering information and far to little on actually going thru it and learning from it. During WWII and the early part of the cold war each and every bit of gathered intelligence was a treasure, troughtly analysed and carfully matched with what other bits of intelligence that was gathered before, letting the analysers build up a pretty complete picture (so good in fact, that towards the end of that war the allies often knew better than the germans where the german troops were). But as we got better at collecting information, through ELINT, satelites and such, we 'drowned' in the sheer amount of information... succumbing to the idea that seeing something was as good as knowing what we saw (hint; it isn't). So I sure hope someone out there figures out a way to both filter and interprent the information they may gather with this - otherwise it is useless.

    *) Come to think of it, the idea to 'sow' enemy territory with a sensornetwork like this before and during an attack might be quite usefull - if they don't figure out a way to jam it off course.

      You're missing the point of government intelligence. As someone (I believe a government official in some totalitarian country - might have been the US...) said, "The important thing is to know something someone else doesn't."

      If you collect tons of useless intelligence, you can then use it to manufacture your OWN intelligence - as the Iraq WMD situation demonstrated very graphically. Anthony Cordesman points out in a recent news piece that the problem was that Bush and Powell couldn't check everything themselves, they had to rely on their intelligence agencies - who were busy manufacturing "evidence" in the usual way - connecting the dots - dots that were really on a Roschach blotter, not an actually existing graph...if you get my meaning...

      The problem is - if you have people connecting the dots for you, you have to be sure they are connecting REAL dots, not random dots. But the intelligence and law enforcement agencies make their living by coming up with dots to be connected - whether they are real or not.

      As Robert Anton Wilson has pointed out numerous times, you can connect anything to anything if you look hard enough. That's what human brains do - interpret patterns - the key word being "interpret". There's plenty of connections between George Bush and the bin Laden family - the same family that many people find are still "linked" to Osama. Does this prove George Bush funds Osama? Well, no, but if someone WANTS it to, it WILL.

      So the more information you have, the better the people whose job it is to "interpret" that information like it.

      Which is why the rule is: when the FBI comes to your door, you say this and ONLY this: "On advice of attorney, I have nothing to say to the FBI." Period. Full stop. If you say ANYTHING else, they WILL use it against you or against anyone else they can...even if you just say, "Well, my brother-in-law said it rained yesterday"...somehow they will find a way to use that to prove that you contacted your brother-in-law and it was raining in Afghanistan yesterday so he must be an Al-Qaeda operative...

      If you think this is paranois, you have never read anything about the FBI or the CIA - or talked to anyone who has been or is in prison in this country.

      • Missing the point? On the contrary, let me quote a single sentence from my original post; So I sure hope someone out there figures out a way to both filter and interprent the information they may gather with this - otherwise it is useless.. Raw data on it's own is nothing but raw data - and pretty much useless.

        As far as manufacturing intelligence goes... thats a dangerous business. Take, as you do, the situation with Iraq and WMD. Yes, we know that they have had them in the past. Yes, we know that they ha

    • Politicians, I fear, face information with a different mind set than the scientific community. I see information, and want to know what I can learn from it. How can I take this information and do something that will improve things?

      Politicians look a information in terms of relative advantage. Does the information provide a way to reward friends and punish enemies? For example, if a scientist had a record of everyone's beer drinking habits, they would wonder what patterns indicate abuse, moderation, etc..

    • That's because without them, Star Trek would be senseless.
    • How about sensors that sense how much electric current in being used and compares that with how much should be used. All electric equipment would be smart enough to know how much it needs and communicate that to a computer. The same could be done with devices that use natural gas or even water. How about back up to fire and burglary alarms to eliminate alot of false alarms. There are many ways sensors could be used to help protect everyone safety.

    The real advantage of sensor networks will come if they provide information that helps companies make better products, or if the increased amount of data gathered actually provides useful information on how things work so that we can advance our knowledge.

    The security issue is a ruse. Security is what is selling today...so it is what you put in ad copy and press releases. It is like the B2B craze...remember when B2B appeared in the investor relation pages for all the dot bombs? Today, you need to have the word security in your ad copy.

    Of course, the fact that we are twisting more and more fundamental research into security concerns is itself a cause for concern. It means the applications will not be benign.

    I suspect that, when all is said and done, the devices themselves will tend to add more reasons to feel insecure than they will do to add reasons to feel secure. The programs will be used as much for spying as for defense. The result is that the primary use of such networks will be to detect and counter the other sensor networks trying to spy on your sensor networks.

    It will be a white-spy black-spy sort a game.

    Perhaps it would be nice to move away from wild, unfounded speculation and Sci-fi references to discuss how these things are used in the real world. Last summer I worked at a research station [greatduckisland.net] where we set up a network of these things to remotely monitor ground-nesting birds in their burrows. Privacy of the birds aside, these are great tools for scientific observation in sensitive areas -- observer effect is minimized, cost is minimized, and you can monitor many different locations constantly, without having to check them again every day. If you're wondering what the limitations of these systems are, powering them is a big one. The motes run on battery power, so the size of the battery puts a restriction on both the size of the mote and the amount of time it can run before it needs to be replaced (and the site needs to be disturbed). And size is important too, as they are not yet quite small or cheap enough to throw one in every locker room (despite what you may have heard).

    These sensor networks sound very promising in that more information and real-time tracking could potentially result in more efficient distribution of resources, better tracking of that letter you sent through the mail system, better control of traffic lights to reduce traffic jams etc.

    However I hope that in the future as our first world societies incorporate these technologies we don't become overly dependent upon them. We're going to become increasingly susceptible to terrorist type attacks in the future and imagine the havoc that could be wrought on a society completely dependent on electronics and nanotech by a few well placed EMP bombs.

    I found the article's comment about the need for the NSF to motivate standards in wireless sensor networks to be strange, since the IEEE 802.15.4 standard [ieee802.org] is due to be published any day now (the final draft is alread for sale at the IEEE online store [ieee.org]). The IEEE 802.15.4 standard is designed for low cost, very low power consumption wireless sensor networks; it has a raw over-the-air data rate of 250 kb/s, operates in the unlicensed 2.4 GHz ISM band, and can support peer-to-peer multihop (so-called "mesh") networks with device duty cycles below 3 ppm.

    The IEEE 802.15.4 standard is being used by the ZigBee Alliance [zigbee.org], an organization of more than 50 large and small companies, to establish networking and application profile interoperability standards, much like Wi-fi has done with IEEE 802.11. The ZigBee Alliance will have a session open to the public at its next meeting, in Berlin June 3.

    The IEEE 1451.5 wireless sensor standard [ieee.org], which will standardize sensor discovery and data formatting, is at an earlier stage of development; proposals are now being presented [ieee.org].

    With all this activity, it's not clear to me just what the NSF is expecting to standardize.
