For the user the new identification system offers the advantages of increased security and reduction of risk in situations where a portable computer, mobile phone or other digital device has ended up in the wrong hands because of loss or theft. The device will become non-usable in the wrong hands. For example, the identity of a mobile phone user can be verified before the phone can be used for banking transactions. Compared with passwords and traditional bioidentification, the new method is simple: confirmation of identity takes place as a background process without any need for user's intervention.
A device is equipped with sensors that measure certain characteristics of the user's gait. When the device is used for the first time, these measurements are saved in its memory. In normal use the device continuously measures the user's gait and compares these measurements with the values in its memory. If they are sufficiently identical, the device identifies and approves the user. If the values differ, standard password-based identification is available.
Gait-based identification is based on advanced computation, where the measured signals are first filtered and then certain parameters the so-called 'gaitcode' are calculated. In initial tests the identification rate was over 90%.
