healthKERI is advancing the future of secure healthcare data exchange through a groundbreaking cryptographic framework known as the Key Event Receipt Infrastructure (KERI). Built for zero-trust, peer-to-peer communication, healthKERI enables self-certifying, authentic data exchange without relying on third-party certifiers or shared governance models. With proven deployment in other industries, this innovative approach to PKI key management and data provenance is now being applied to healthcare—reducing attack surfaces and redefining what secure, verifiable data sharing looks like. At healthKERI, the principle is simple: Sign everything, trust nothing.
