Biometrics and AI
Biometrics is the technique that utilizes the distinct genetic features collected from face, thumb, retina, eye etc. as an of authentication code. The number of valid biometrics is finite for a human. Any person who enrolls in multiple organizations, would have to use his/her different biometrics as mentioned above, so that there is fool proof authenticity, without any possibility of tampering of the biometric data of one organization by the other. But an innovative idea would be to use a technique that utilizes the same biometric in different organizations.
