Breathing Patterns: A Unique Biometric Identifier?

A new study suggests that a person's breathing pattern, much like fingerprints, could be unique. Researchers tracked the breathing of 97 healthy individuals for 24 hours and found they could identify participants with high accuracy based solely on their breathing patterns. These patterns also correlated with BMI and signs of depression and anxiety, suggesting breathing analysis could be a powerful diagnostic tool. The study indicates that it may be possible to 'read the mind through the nose'.
