Human-to-Machine Communication (HMC) optical sensor supplier VocalZoom has released voice biometrics technology using its optical sensor that performs all voiceprint acquisition and embedded template matching, eliminates the microphones and noise reduction software of traditional acoustic solutions, and takes voiceprint verification out of an external processor or cloud-based server to the security of an embedded, match-in-sensor architecture, the company said.
VocalZoom´s patented VoiceMatch-in-Sensor technology for embedded speaker verification products acquires data from users during the biometric enrollment process as their facial skin vibrates during speech.
The VocalZoom optical HMC sensor converts this data into a voiceprint associated only with the person who was actually speaking, and stores it inside the sensor. This enables the sensor to meet FIDO compliance requirements, enabling easy plug-and-play installation as compared to existing fingerprint or other biometric sensors that don´t offer secure embedded biometric acquisition and template matching.
Each time users authenticate, a voiceprint is again acquired in real time, again optically confirmed to be from a living person rather than a recording, and then securely matched inside the sensor solution against information in its embedded template to verify the user and complete the authentication process.
The match-in-sensor architecture for embedded speaker verification has been proven with fingerprint biometrics, but was previously unfeasible for voice biometrics because of the cost, complexity and vulnerabilities associated with acquiring voiceprints using traditional acoustic technology.
VocalZoom supplies Human-to-Machine Communication (HMC) sensors for delivering a, natural, personalized and secure voice-controlled user experience in today´s increasingly mobile and interconnected world. The sensors enable accurate and reliable voice control and biometrics authentication in any environment, regardless of noise. Applications including mobile secure payments, headsets and wearables, mobile phones, access control, smart home solutions, and hands-free automotive voice control.
