Research into new uses of biometrics is blossoming. Iris and fingerprint scans as well as facial and voice recognition are just a few of the biometrics tools that can improve security while making lives easier, biometrics researchers say. Such biometric security may effectively eliminate the need to create and frequently change passwords.
Some Purdue University researchers are working on technology that could see all those passwords that computer users must punch in replaced with steps such as iris and fingerprint scans.
Iris and fingerprint scans as well as facial and voice recognition are just a few of the tools that can improve security while making lives easier, said Stephen Elliott, the center's director. That technology can allow someone to log into a computer or activate a smartphone simply by swiping their fingerprint over a sensor -- and eliminate the need to frequently change passwords.
