More unique than a fingerprint: scientists have created an authentication system based on exhalation
[ad_1]
Scientists from India have developed a user authentication system based on the physics of human exhalation.
They researched that this action identifies a person no worse than a fingerprint, writes New Scientist with reference to an article on arXiv.
To train the artificial intelligence and build the system, the developers collected data on 10 exhalations from 94 volunteers using a thermoanemometer, which measured the speed and temperature of the air flow.
The artificial intelligence was able to distinguish the exhalations of the participants with an accuracy of 97%.

Due to the different location of the organs inside each person, the lungs, trachea, larynx and oral cavity together create a unique exhalation.
Scientists also believe that such an identification system will be more difficult to bypass than fingerprint authentication – it requires a conscious person to unlock it.
Scientists assume that their development will eventually be able to replace the analysis of fingerprints, the retina of the eye or the face.
It will be recalled that scientists have established that all human fingerprints are actually not unique.
