BlockID is a digital identity platform that combines identity proofing, biometric authentication, and passwordless access control. The platform verifies user identities through document validation and biometric verification, then stores encrypted user data on a private blockchain. BlockID performs identity proofing by capturing and validating information from government-issued identification documents including driver's licenses, passports, and national ID cards from multiple countries. The system reads RFID chips and detects photocopies during document verification. For biometric verification, the platform uses facial recognition technology that requires users to perform randomized facial movements during a selfie video to confirm liveness. Authentication methods include facial biometrics, device-based biometrics, and hardware security keys. The platform uses FIDO2 certified private-public key pairs stored in device security modules for data access control. BlockID supports continuous identity verification for organizations managing access to systems, applications, and data.
