swIDch FIDO is a biometric authentication solution based on the FIDO (Fast Identity Online) international standard. The product enables passwordless authentication using biometric information such as fingerprints, faces, and voices stored locally on users' mobile devices rather than on external servers. The solution stores biometric data in hardware security components allocated to each user's mobile device, including TrustZone, USIM chips, IC chips, and HSM chips. Only authenticated data is transmitted to external servers, while the actual biometric information remains on the device. The product supports multiple authentication methods including fingerprint, face, voice, and security key authentication. It implements public key cryptography and digital signatures for authentication processes. The solution is designed to replace traditional ID and password authentication systems. SSenStone, the parent company of swIDch, holds FIDO Alliance certification for multiple components including FIDO 1.0 Universal Authentication Framework (UAF) and FIDO2 standards. The certified components include FIDO Server, FIDO Client for iOS and Android, and FIDO Authentication modules. The solution addresses password-related security issues such as password leakage, password reuse across multiple accounts, and the burden of managing complex passwords. It provides authentication capabilities for various use cases including fintech, online finance, digital signatures, non-face-to-face transactions, and electronic contracts.
