Scientists have developed a bioacoustic identification technology that allows you to identify a person’s personality from the sound of the body as accurately as from fingerprints and the iris of the eye..
Every sound we hear has a unique signature associated with how it was created and what objects its waves passed through. Therefore, a group of researchers decided to study whether the unique bioacoustic signatures created by the passage of sound waves through people can be used to identify them..
Biometric system developed by team of the South Korean Research Institute of Electronics and Telecommunications, uses a transducer to generate vibrations that pass through a specific part of the body, such as a finger. After the sound waves have passed through the skin, bones and other tissues, the sensor determines their unique bioacoustic signature.

The approach is effective enough to distinguish between different fingers of the same hand. It means that for authentication, the person must use the same finger that was originally analyzed. Scientists also found that the spectral pattern of human bioacoustics persisted over time, despite the constant renewal of body cells..
Although the measurement of acoustic vibrations is quite accurate, it is still inferior to the analysis of fingerprints or the iris. Therefore, in the future, the team plans to improve the system with additional sensors. However, they are already exploring ways to commercialize the technology in phones and wearables..
Moreover, the technique analyzes tissues so accurately that the team began looking for ways to use it to diagnose diseases of the musculoskeletal system..
In addition to people, with the help of sound you can to identify any other objects, and in conjunction with machine training this opens up new possibilities for the interaction of gadgets with them.
