ZeroBiometrics proposes linking AI agents to the identities of real humans using its biometric cryptographic technology. Frontegg.ai gives developers an identity layer with a multi-tenant onboarding flow, enterprise-grade policy controls, token rotation and security controls to support both B2B and B2C agent applications. Silicon Valley-based Anetac has launched the new Human Link Pro software to provide real-time visibility into human and non-human identities across chains.
