At Unissey, we are developing a biometric authentication solution. Our solution verifies an identity instantly while detecting fraud attempts: photos, videos or masks intended to fool conventional facial recognition systems. It only takes one second to authenticate oneself. To improve the user experience, we have designed the first completely passive facial authentication solution. No more need to interact with your phone to prove your existence. Thanks to our Computer Vision and Deep Learning algorithms, we offer a robust and seamless identity verification.
