Zusammenfassung:A multimodal biometric authentication system utilizes a bulk absorption characteristic of human tissue that is measurable using a photoplethysmography (PPG) sensor. One disclosed method of operation includes extracting bulk absorption features from biometric data obtained using a PPG sensor and generating a first biometric template. Additional biometric features are also extracted from biometric data obtained using a second biometric sensor and a second biometric template is also generated. An authentication output signal is provided in response to the first biometric template matching a first stored corresponding enrolled biometric template and the second biometric template matching a second stored corresponding enrolled biometric template.
