Skeletal Identification 76

Bruce Schneier noted a story today over at his blog about a new Skeletal Identification System being developed at Wright State. Of course this is just another biometric detection system, but one that would be pretty tough to disguise.

    I imagine there may be some issues with irradiating people to identify them. This isn't something on the surface you can just get with backscatter terahertz. Imaging bones means X-ray, and a fair bit of it for a full-body image. They might be able to get it down to the equivilent exposure of one plane flight - but add up all the airports, ports, theme parks and places adults may encouter children each year. That's a potential legal risk, if nothing else.

    On the other hand, if someone suggested imposing manditory x-ray exposure as a means to identify pedophiles, most people would probably suggest positive results be given an extra-high-intensity scan just to confirm it with a clearer image.

    • These kinds of scanning do not use x-rays, rather monochromatic red light (primarily for eye-safety). They work by imaging the light by a red laser using a digital camera and transforming a 2D plane into a 3D object (surface) by reconstructing multiple views. The problem using these scanners is not that people would suffer harm from the beam, unless they looked directly into the laser, rather problems would come from artifacts produced by hair, clothing, etc that would mask the shape of the face and body,

        Although their language is somewhat vague ("other forms of body scanning" is open to interpretation), they clearly are not ruling out x-rays, and are obviously leaning towards a form or radiation that would penetrate the body, rather than reflect off the surface, and the exposure would be measurable and significant.

    Myriads of automated, interconnected tracking and identification systems available to all, implemented in any storefront and doorway for security and insurance purposes. Full identification on visual contact. Privacy will become a right on paper only, requiring a vast security team to implement in practice, perhaps even breaking some laws. What should hackers do? Help dying privacy rights, with arcane tools nobody can use? Expose the tracking systems is pointless, everyone knows about them and has one. Leak their data? Leak the identities and actions of those hidden entities, who are abusing the law with it? Eliminating the last of all privacy-capable individuals? Looks to me like Wikileaks is the future for privacy activism.

    This article reads like a parody. Some guy is (supposedly) worried about sex offenders in the neighborhood - I know, let's X Ray everyone everyday ! That will surely keep people safe, until they all die of cancer.

    Seriously, are these guys stuck in the 1950's ? Penetrating radiation for bone scans ? On a daily basis ? I can remember when children's shoe stores had X ray machines, so Mom could view how the shoe fit, but such common uses of X Rays were stopped for a reason, and as a screening device this has no chance.

    From the article : Depending on the selected technology, a skeletal scan would only expose a person to radiation that is the approximate equivalent of taking one cross-country airline flight

    From the World Health Organization, INFORMATION SHEET Nov. 2005, on Cosmic Radiation and Air Travel : [who.int]

    Aircrew are now recognized in many countries as occupationally exposed to radiation, and radiation protection limits for aircrew are similar to those established for nuclear workers.

    If you work through the numbers (and I read the above to mean that, at best, radiation exposure would be similar to air travel, so this is a lower bound), a daily scan would thus amount to 2 to 5 milliSievert (mSv) of radiation each year, substantially exceeding the ICRP guideline of no more than 1 mSv exposure to any fetus during pregnancy, and coming close to or exceeding the guideline of 4 mSv exposure for ordinary workers.

    This would, at a minimum, mean that anyone at risk of pregnancy should not be scanned, and radiation workers should not be scanned (as they are typically close to their limits). There is thus just no chance that this would be adopted for regular screening of the general population.

  • They state that "a skeletal scan would only expose a person to radiation that is the approximate equivalent of taking one cross-country airline flight", but If they implement it as they hope, to "scan the skeletal structures of people at airports, sports stadiums, theme parks and other public places that could be vulnerable to terrorist attacks, child abductions or other crimes" - how much radiation is that per year?

    Interesting, but... The scheme fails to account for the fact that human bones remodel and change shape over time. In fact, the premise appears to count on the fact that people's bones will remain unchanged. It's just not so. The skeleton is a changing organ. More info can be found in this wiki: http://en.wikipedia.org/wiki/Bone_remodeling [wikipedia.org] One could imagine a database of "bone information" that is cross-referenced to identity. While it's possible the data would initially be useful, over time the database would become increasingly inaccurate as peoples' bones changed. How often would the authors suggest that people be rescanned to maintain accuracy?
