Your walk can give you away

London, Oct 9 (IANS) The way you walk could give you away as accurately as fingerprints - but only if you walk without your shoes.

Researchers have developed a method that can identify a unique “pressure signature” in individual footsteps.

By analysing more than 100,000 pressure points created by people’s feet as they walk, the scientists were able to pinpoint 70 key patterns that are unique to an individual, the Telegraph reports.

The system could provide a new form of “biometric” identification that could work alongside retinal scanning and fingerprints at airports.

The only snag is that it won’t work if people are wearing shoes. John Goulermas, electrical engineer at the University of Liverpool, was hopeful of developing the system so it will work when people are shod.

“This is more complicated as the stiffness of the sole and the treads can change things, but it should still be possible,” said Goulermas.

Researchers asked 104 volunteers to walk across boards studded with thousands of highly sensitive pressure sensors. They recorded 10 steps per person and then analysed how each persons step changed to produce a unique profile for each person.

When asked to then identify individuals from their footsteps, the system was correct 99.6 percent of the time.
