GhostPass Inc. is a fully decentralized biometric authentication solution company that ensures users maintain sovereignty over their biometric information by securely storing it on their own smartphones. This technology is patented and is the first of its kind. Unlike conventional storage methods utilizing servers and/or the cloud, access to biometric information by third parties is structurally impossible and there are no concerns about monitoring and misusage. Furthermore, the risk of mass leakage of biometric information is fundamentally prevented.
