Invented a new technology for identifying a person by body sound

Scientists have developed a bioacoustic identification technology that allows you to determine a person’s identity by body sound as accurately as by fingerprints and iris.

Every sound we hear has a uniquea signature related to 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 a team from a South Korean research instituteelectronics and telecommunications, uses a transducer to generate vibrations that pass through a specific part of the body, such as the finger. After sound waves have passed through the skin, bones and other tissues, the sensor determines their unique bioacoustic signature.

The approach is effective enough to distinguishdifferent fingers of one hand. This means that for authentication, a 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 isaccurate enough, but still inferior to the level of fingerprint or iris analysis. Therefore, in the future, the team plans to improve the system using additional sensors. However, they are already exploring ways to commercialize technology on phones and wearables.

Moreover, the technique analyzes the tissues so accurately that the team began to look for ways to use it to diagnose diseases of the musculoskeletal system.

In addition to people, with the help of sound you can identify any other objects, and in combination with machine learning, this opens up new possibilities for the interaction of gadgets with them.
