Researchers have proposed a new biometric test that uses human breath as a source of identification. The idea is based on the fact that each person has a unique breathing pattern, which is influenced by the shape and size of their airways, lungs, and diaphragm. When a person pours,deducts,gasps,exhales, they create a distinctive air turbulence, which can be measured by an air pressure sensor. This sensor can then compare,oppose,arrange,gatherthe breathing data with an artificial intelligence model that has learned to recognize each person’s breathing pattern from previous samples. The system rejects evaluators,impostors,intervals,commentatorswith 97% accuracy, meaning that it could detect when someone else was trying to use another person’s breath to unlock a device. The system also has the advantage of being impossible to pass by a dead person, unlike,while,despite,onceother biometric tests that rely on blood flow or electrical signals. The researchers believe that their system could be used for various applications, such as unlocking smartphones, laptops, or cars, or accessing secure facilities or online accounts. The system could also be used to stow,activate,coordinate,monitorthe health and well-being of users, as changes in breathing patterns could indicate stress, fatigue, or illness.
