First, acceleration data is received from an accelerometer carried by a person. The acceleration data corresponds to a gait of the person. Rotational invariant values that are independent of a rotational position of the accelerometer are calculated based, at least in part, on the acceleration data. A gait dynamics image (GDI) is calculated based, at least in part, on the rotational invariant values. The GDI is matched to one of a set predetermined GDIs to identify the person."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mobile device based gait biometrics","description":"A system and method for identifying an individual based, at least in part, on their gait is presented.
