Technical Description

The software’s anti-recording technology prevents an imposter from gaining unauthorized access with a recorded passphrase. The user utters a voice passphrase just once to enroll, and the passphrase can be changed at any time. When a user's voice has changed, for example due to strained vocal cords, the user simply re-enrolls to add a new model in just a few seconds. The software is robust to background noise. LcT has patented several technologies to support this feature, including auditory-based models, dual microphone array, and noise cancellation and reduction. Finally, the software is language independent, which means the user can utter a passphrase in any language.

In a third party database evaluation of over 100 subjects, the software achieved near 100% accuracy. Both false rejection and false acceptance rates were nearly 0% in different noise environments

Sales and Licensing

The software is ready for licensing to mobile device manufacturers, financial institutions, solution providers, and mobile chip manufacturers. LcT can deliver cloud servers to financial institutions with pre-installed software. The software can provide a biometric solution for any application that requires strong user authentication. The software can be packaged as an app or cloud engine. One working app is to use voice to luck/unlock an smartphone.
