Identification and verification - Voice authentication, facial recognition, biometric solutions

Authenticate customers with biometrics

As the market leader in biometrics, Nuance can help you identify and verify your customers—simply and securely with their voice, face, or other modalities.

Voice and facial biometrics: Simpler, stronger authentication

Start each customer interaction with effortless authentication. Nuance has pioneered many applications for voice and facial biometrics—passive and active authentication, fraud prevention, public security, network password reset—to provide solutions to organizations worldwide.

Voice authentication overcomes knowledge-based security issues by analyzing your customer’s voice for hundreds of unique characteristics, then matching to a voiceprint file. With face recognition, users authenticate in real time by taking a selfie that is compared to an image on file, achieving high levels of confidence by overcoming facial variances. New technology will soon detect liveness and potential fraudsters using a photograph.

What voice biometrics can do for you—and your customers

Think of knowledge-based security as sprawl: when one level becomes ineffective, another level is added. PINs become passwords. Passwords require security questions. And your customers need to remember it all. This adds stress to their experience with your brand, and delays customers from completing their task.

Voice biometrics eliminate the sprawl by using your customer’s unique voiceprint for authentication. It can be passive, where users say anything and their voice is matched to a voiceprint. Or active, where callers are asked to recite a passphrase. Either way, voice biometrics provide a natural, effortless, and more accurate way to authenticate.

A four-digit PIN is the weakest credential, as it’s often shared and a brute force attack can quickly compromise it. Passwords and security questions can be successfully answered with simple web searches of the account holder. Unlike knowledge-based security, voice biometrics cannot be compromised in this way.

Voiceprints are hashed strings of numbers and characters, so it has no value to a hacker. Plus, each time a fraudster speaks within an IVR, call center, or mobile app, they leave behind their own voiceprint that can be used to proactively keep them out of the system—and even alert law enforcement. The power of voice is in your hands.

The best call center agents focus on providing great service to happy customers. Unfortunately, before they can provide great service they must authenticate the customer, typically through a series of challenge questions.

By eliminating PINs, passwords, and challenge questions, agents can engage customers quickly. Which makes both customers and agents happy, and impacts the bottom line. After implementing Nuance voice biometrics, a large European financial institute saw an 8% reduction in absenteeism—translating to hundreds of thousands of dollars in savings.
