Scientists find various audible frequencies in a person’s laugh can be used to create digital signature.
In a world where tens millions of people use ‘12345’ or ‘qwerty’ as their passwords, it makes a great sense to use biometric security instead, as every human being has multiple unique biometric signatures that can be used instead of a password.
This could all change soon after scientists revealed that laughter is unique to every person and can hardly be spoofed. A team from the Systems Engineering Department at the University of Lagos in Akoka, Lagos, Nigeria, have discovered that people can identify other people by the matchless nature of their laughter because, unlike voice and manner of speech, laughter almost cannot be mimicked.
