ABSTRACT
We have created a system for identifying people based on
their footstep force profiles and have tested its accuracy
against a large pool of footstep data. This floor system may
be used to identify users transparently in their everyday
living and working environments. We have created user
footstep models based on footstep profile features and have
been able to achieve a recognition rate of 93%. We have
also shown that the effect of footwear is negligible on
recognition accuracy.
