ZenGo's biometric security combines privacy and security. Our recovery system scans for both signs of likeness and liveness so that it is it cannot be spoofed by either a picture or a video and is even secure against 3D masks. ZenGo also only stores their customer's biometric information as an encrypted 3D facemap that is both unidentifiable and unusable, except to the customer. That way, only our customers can restore their accounts and their information always remains private.
