Abstract

The present invention relates to a method and system for identifying a subject (5). In order to provide abiometric identification technology, which is highly accurate, non-invasive, simple to implement, and resistant to spoofing, a method is suggested, comprising the following steps: carrying out a Doppler radar measurement to obtain a Doppler radar signal (9) representing information on the mechanical activity of an inner part (4) of the subject s body, e.g. the subject s heart; determining the characteristics of said mechanical activity from said Doppler radar signal (9); and identifying that subject (5) using said characteristics.
