BIOMETRICS ARE THE NEW FINGERPRINTS!

It has often been said that each persons swing is unique like a snow flake so that no two golfers swings are the same. Now comes some evidence that this may in fact be true, at least when it comes to your swing and its footwork. Research done by Piotr Porwik etal, (http://zsk.tech.us.edu.pl/publikacje/08-Proksa.pdf ) has established a connection between how humans change their center of gravity and how you can identify the person by recording foot pressure profiles – how you stand is so unique that it reveals who you are.

Other biometrics are more common for example the iris of the eye or fingerprints used to identify people because they describe a unique characteristic either physiological or behavioral features that are exclusive to all but the person. Finger prints would be hard evidence, as is DNA — hard meaning that a jury of experts would accept such evidence as far as identification goes [unless of course it were the OJ Simpson jury.] 

    Modern biometric solutions have been introduced in which movement profiles such as the human gait, or handwriting, while still strong is not as ‘hard’ as physical biometrics. It is in this second category that the findings of the researches mentioned above take their place.

    The researchers asked subjects to stand on pressure sensitive pads in the form of a left and right foot. A computer recovered center of gravity changes as they stood without moving off the pads. The human body undergoes constant mini-movements most of which are related to balance requirements even when it appears as if the body is stock-still. Once these mini-movements were analyzed, a unique profile was constructed from which the individuals  could subsequently be identified by the pressure changes in their feet, a result of postural mini-movements.

     In my personal experience I have found that once learned the golf swing becomes a bio-metric so individualist that I can identify a person by their swing even though I can not see their face.  From a 100 yards away you are your swing -- and while the distance may wipe out the paunch and the facial features, a persons golf swing announces his or her presence.

     If OJ had left a picture of his swing at the crime scene rather than his DNA he would have been convicted for sure.
