Facial biometric recognition works well on clear images with a good view of the face, but much additional data is often discarded due to the fact that the face, or the full face, is not clearly visible. The discarded data contains “soft” biometrics, such as height, gait and other features, such as ears.
Perdue University researchers are working on technology that could enable users to replace passwords with iris or fingerprint scans, The Associated Press reports.
The researchers are testing emerging biometric technologies for weaknesses in the basement lab of Perdue University’s International Center for Biometrics Research. Iris and fingerprint scans, as well as facial and voice recognition, are just a few of the tools that could eliminate the need to frequently change passwords.
Users of iris biometrics would not need to re-scan eyes for up to nine years, the NIST research suggests, as age doesn't affect eyes as quickly as previously thought.
