Speeding Into the Future With Biometrics

Imagine checking in for a flight by simply walking onto the plane. Or buying groceries with a nod of your head, or withdrawing funds from a ATM with a single glance. Thanks to biometric technology - which uses voice, face, fingerprint, or other physical or behavioral characteristic recognition to 1 verify an individual's identity -- those scenarios are not far from becoming reality.

Rapid user identification and more intuitive(简便的)shopping 2 are just a couple of the emerging capabilities of biometrics, which is ready to blossom into a $ 59.31 billion global industry by 2025, according to Grand View Research. Whether it's providing better ways to fight fraud or delivering smarter customer service, the biometrics industry is expanding the 3 applications of the technology and transforming human interactions across business and government.

Tools that enable voice recognition, iris recognition, and other methods of identification offer faster and more 4 ways to access electronic devices or physical locations by creating unique identifiers such as "voice-prints" and "eye-prints" that can't be faked. They also allow users to maintain consistent digital identities wherever they go.

Millions of smart-phone and tablet users already rely on finger-print scanners and facial recognition systems to unlock or manipulate their devices, but more sophisticated solutions are being 5 or are in development across a variety of industries.

"The future of business lies in highly intelligent and automated transactions and smart, faultless customer interactions," says Brett Beranek, general manager of security and biometrics at Nuance Communications. "Among today's fastest-growing trends, the 6 toward more nautral and personalized exchanges is quickly making biometrics a go-to technology for firms all around the world, including Fortune 500 leaders."

Nuance has been developing its 7 biometrics technologies over the past two decades. Its tools go beyond identifying simple characteristics, such as the sound of an individual's voice, to learning speaking, typing, and behavioral patterns and memorizing 8 vocabulary. Such capabilities allow the technologies to recognize when someone is trying to impersonate a customer on the phone or during digital transactions, stopping fraud in its tracks.

Nuance's technology is not only capable of identifying who is 9 with it, but also what the user is likely looking for, enabling personalized interactions from the moments they begin. This friction-less experience can be a competitive advantage - driving 10 and improving customer satisfaction.
