  Security first: When a footstep is like a fingerprint  
 (AFP) –  1 day ago         
 PARIS — How a bare foot strikes the ground as one walks reveals your  identity almost as well as a fingerprint, according to a study released  Wednesday. 
 The discovery means that one day retinal scans, voice  recognition and old-fashioned mugshots may be joined by foot-pressure  patterns as a means of confirming ID, it suggests. 
 Previous  research has shown that everyone has a unique stride. Computers can  determine “gait patterns” – the way a person walks, saunters, swaggers  or sashays – with up to 90-percent accuracy. 
 Scientists led by  Todd Pataky at Shinshu University in Tokida, Japan, looked at enhancing  this finding by measuring how the foot hits and leaves the ground during  walking. 
 They used 3-D image processing and a technique called  image extraction to analyse the heel strike, roll-to-forefoot and  push-off by the toes among 104 volunteers. 
 Footstep patterns were  matched to the individual with 99.6 percent accuracy, according to their  paper, published on Wednesday in Britain’s Journal of the Royal Society  Interface. 
 The study is “proof of concept,” meaning that it was  carried out in experimental conditions among volunteers who were  barefoot to see whether the theory was sound. 
 In an email exchange with AFP, said the technology would be useful in security checks. 
 But  it would only work in situations where an individual wants to be  recognised, “since anyone can modify their gait,” he explained. 
 “Automated  airport security checks, ATM security, controlled building access – in  all these cases, an individual could walk normally to be positively  identified.” 
 Further work is needed to see whether feet that are shod throw up similar telltale patterns. 
 “We have some pilot data for walking with shoes, but have not yet conducted systematic testing,” Pataky said. 
 Too cool, eh?
