User authentication system based on human exhaled breath physics. (arXiv:2401.02447v1 [cs.CR])

This work, in a pioneering approach, attempts to build a biometric system
that works purely based on the fluid mechanics governing exhaled breath. We
test the hypothesis that the structure of turbulence in exhaled human breath
can be exploited to build biometric algorithms. This work relies on the idea
that the extrathoracic airway is unique for every individual, making the
exhaled breath a biomarker. Methods including classical multi-dimensional
hypothesis testing approach and machine learning models are employed in
building user …
