Researchers at the Electronics and Telecommunications Research Institute (ETRI) in South Korea have developed a biometric system that uses a transducer to generate vibrations and sound waves that can be used to identify individuals.

After the sound has passed through the skin, bones, and other tissues, a sensor picks up the person’s unique bioacoustic signature.

Analysis of the distinct signatures of individuals is boosted by modeling, which allowed the researchers to infer which structures of the human body actually differentiated people.

The method, however, does not yet match the accuracy of fingerprints or iris scans for the identification of individuals.
