In modern healthcare, clinical information is increasingly exchanged as structured data, such as FHIR or JSON, between independent systems like hospitals, pharmacies, and regulatory bodies. In this distributed ecosystem, guaranteeing the integrity of the clinical content—proving that it has not been altered since it was signed—is as critical as verifying the identity of the signer.

The core problem this document addresses is the failure of traditional digital signing models to provide durable, cryptographic proof of content integrity for structured data over the long term. Many conventional systems can prove who signed a transaction but cannot cryptographically prove what exactly was signed, leaving a critical security gap in workflows for prescriptions, medical orders, and regulatory submissions.
