Abstract
A system to remotely identify a person by utilizing a microwave cardiogram, where some embodiments segment a signal representing cardiac beats into segments, extract features from the segments, and perform pattern identification of the segments and features with a pre-existing data set. Other embodiments are described and claimed.
Claims8
A system for biometrically identifying a person using microwave radiation, the system comprising at least one processor configured to segment a microwave cardiac signal comprising cardiac beats into segments, to extract features from the segments, and to perform pattern identification of the segments and features with a pre-existing data set;
- wherein the microwave cardiac signal is obtained from reflected microwave radiation comprising an electrocardiographic waveform and an impedance-cardiographic waveform.
A method for biometrically identifying a person using microwave radiation, the method comprising:
- segmenting a microwave cardiac signal comprising cardiac beats into individual segments, wherein the microwave cardiac signal is obtained from reflected microwave radiation comprising an electrocardiographic waveform and an impedance-cardiographic waveform;
- extracting features from the segments;
- and
- performing pattern identification of the features in the individual segments with a pre-existing data set.
