Mobile devices, such as smart phones, often contain personal and confidential data -- and are very vulnerable to theft and loss. To prevent unauthorized use, most devices rely solely on single-factor password security. Unfortunately, passwords offer relatively weak protection as they can be forgotten, observed, stolen or hacked.
Voice biometrics, on the other hand, can provide robust security and is also a natural fit for smart phones and other mobile devices with a microphone. Let’s see how the technology would work with mobile devices. There are two approaches:
• Embedded – all voice biometrics functionality (enrollment and verification) is self-contained on the mobile device
• Remote – some voice biometrics functionality (e.g., “voiceprint capture”) resides on the mobile device and the remaining functionality lives on a server
Several organizations are actively engaged in developing voice biometrics solutions for the growing mobile device market.
