Amidst ongoing debates about the superiority of fingerprint-based and face-based biometric security systems, researchers at the University of Albany in the US have come up with a novel approach - using sweat!
This new biometric authentication approach which uses body sweat might be one of the most secure ways to unlock smartphones and other wearable, smart devices, say scientists.
Why a new biometric authentication system is required
"Passwords and pins can easily be seen over someone's shoulder...there are many internet tutorials on how to create a fingerprint mold that is capable of opening a device. There are also issues with facial recognition," said Jan Halamek, a University of Albany assistant professor.
