The Wright State Research Institute is developing a ground-breaking system that would 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. The images would then quickly be matched with potential suspects using a database of previously scanned skeletons.
The adult skeleton has 206 bones. Size, shape, density and joint structure make each skeleton slightly different. Throw in an extra lumbar vertebrae or extra rib as well as previously broken bones, implants, screws and other identifying characteristics, and the signatures become even more individual. And the skeletal structural features are fairly stable throughout adulthood. X-rays, gamma rays or other forms of body scanning would be used to create a bone signature for each person. Wright State researchers are currently working on identifying key elements and measurements of the skeleton that differentiate one person from another.
