iCrypto Trusted Digital ID / Attestation technology is comprised of multi-tenanted Single Sign On (SSO) coupled with a cloud-based distributed LDAP Directory containing user records from USAF Global network. iCrypto eliminates the need for username and password by enabling secure credential-less access while leveraging biometrics of the user, thus enabling single sign-on for all applications. Designed to be used with the entire suite of iCrypto cloud-based services, the iCrypto SDK can integrate into existing Enterprise Apps or when deployed as iCrypto App be used as a standalone one step password-less verification solution. By employing the latest cryptography technologies in combination with device level security and management, the iCrypto SDK is a secure software token that can be used as mobile biometric ID in a wide variety of industries. iCrypto SDK provides authenticator PKI signatures, range of cryptographic protocols such as TOTP/HOTP/OCRA/MTP, push based authentication, on-device as well as network based biometrics such as fingerprint, iris scan, face/voice/eyeball recognition, third-party authorization, secure storage, and context collection together with security features such certificate pinning, encrypted storage, multi-channel .security and deep network operator integration.
