In a world where tens of millions of people use “12345” or “qwerty” as their password it makes sense to use biometric security, since every human has multiple biometric signatures.
Unique biometric signatures that can be used as an unassailable password, and which would be much more effective than current ones.
A research team has just revealed that laughter is unique to each person and can hardly be falsified. Oluwatoyin Popoola, Olumuyiwa Sunday Asaolu and scientists from the Department of Systems Engineering at the University of Lagos in Akoka, Nigeria, have made a discovery. People can identify other people by the unmatched nature of their laughter because, unlike the voice and way of speaking, laughter cannot be imitated entirely.
To this end, researchers identified various audible frequencies in a person's laughter that can be used to create a digital signature similar to a key created by fingerprint readers.
Unassailable password: we are not quite there yet
According to the study published in the International Journal of Biometrics, the recognition algorithm the team created is 90% accurate, which may be good enough for some consumer applications.
For example, laughter-based security could replace the use of voice recognition. Meanwhile, for systems that need to be very secure and predictable, the accuracy of the laughter recognition algorithm needs to be improved to achieve a 100% uncrackable password.
“Laughter has proven to be a viable biometric feature for person identification that can be integrated into AI systems in several applications”, concluded the team.
So funny!
One potential problem with using laughter as a biometric signature is that the system using it for secure access must make people laugh. Everyone has a different sense of humor and what seems funny to one person is not to another.
I can't imagine an ATM making jokes to get me to access my account. Or a mobile app in which instead of the login form there is a stand-up comedian who titillates my sense of humor. What about hackers and robbers? Will they tell us point-blank jokes to extort a laugh from us and steal everything from us?
I infer that laughter can be used as a digital signature or for others Informatic Systems. However, they are unlikely to be needed for systems that require quick access.
There's nothing to laugh about, in short.
