A breath of fresh air? Breath biometrics proposed by Indian researchers

A group of researchers is breathing life into a new biometric system that could identify a person  by measuring the way they breathe, specifically their exhalations.

Each of us breathes in a different way. During exhalation, air passes from the lungs through the complex internal structures of our airways which creates turbulence signatures – a unique biomarker. Scientists from the Indian Institute of Technology Madras in India have now created a biometric algorithm based on measuring the turbulence in an …
