Biometric Derived Keys introduced by Tech5 enable encrypted sharing of identity data through selective disclosure while addressing legacy vulnerabilities. The new T5-AirKey generates an ephemeral key from the biometric capture of a user’s face, fingerprint, or any other biometric modality. The key is unique, random and irreversible, according to the announcement, and generated in real-time. Tech5 also suggests it will enable better biometric approaches to identity and access management (IAM) and solutions based on or similar to passkeys.
