US 2018/0018509 A1 · INDOOR IDENTIFICATION OF INDIVIDUALS THROUGH FOOTSTEP INDUCED STRUCTURAL VIBRATION

Abstract

This invention introduces an indoor person identification system that utilizes the capture and analysis of footstep induced structural vibrations. The system senses floor vibration and detects the signal induced by footsteps. Then the system then extracts features from the signal that represent characteristics of each person's unique gait pattern. With these extracted features, the system conducts hierarchical classification at an individual step level and at a collection of consecutive steps level, achieving high degree of accuracy in the identification of individuals.

Dependent claims

A system for identifying individuals in a structure comprising:

a vibration sensor, disposed on a walking surface in said structure;
and
a processor, in communication with said vibration sensor, said processor running software performing the functions of:
receiving, from said vibration sensor, a signal representing vibrations generated by one or more footsteps of said individual;
extracting, from said signal, one or more discrete footstep signals;
extracting, from each of said one or more discrete footstep signals, one or more features;
and
identifying said individual, said identification being based wholly or partially on an analysis of said one or more features.
