Over the next five years, a combination of unique biological identity and biometric data, such as facial definitions, iris scans, and voice files, will replace the current user ID and password system for safeguarding personal identity and information, predicted David Nahamoo, IBM fellow and speech chief technology officer.
Nahamoo explained that there are three primary methods of authentication: things we have, such as a badge or ID card; things we are, such as how we look, speak, and walk; and things we know, such as a password.
?The question has always been, why should we just rely on things we have and things we know. Why not bring in the third part, things we are, which is the area of biometrics??, Nahamoo told Infosecurity. ?A single biometric has been falling short of providing secure authentication. But we know that by mixing multiple biometrics, we can get there?, he explained.
