The prescription. The dispensing. The chart. The patient. Proven at every hand.
The order does not transmit, the dispense does not complete, and the chart does not open unless the accountable human signed for it, or signed the boundary it falls inside. Not the prescribing identity alone, every acting party: the clinician ordering, the pharmacist dispensing, the patient consenting. Each signs on their own device.
The Problem
Hospital workflows still run on shared authentication. Computer-on-wheels carts pass between clinicians with cached sessions. The hospital owns the hardware and the credential cache. It does not own a record of who was in the chair at the exact moment a controlled-substance order left the EHR.
The pharmacy counter is a second, quieter gap. A prescription is picked up by whoever presents the card and knows the address. The DEA receives an audit trail that says a prescription was dispensed, not cryptographic evidence that the pharmacist of record was present, that the patient of record received, or that the two sides agreed.
After-hours chart access is the third gap, increasingly urgent under modern privacy frameworks. A clinician at home at 2am opens a patient chart from a personal device. HIPAA minimum-necessary is a regulatory intent, the evidence that the doctrine was upheld does not exist in the audit trail.
What Yuthent Provides
Three places authentication does not reach. Three places Yuthent does.
The mobile-first clinician. Replace the shared keyboard with the device already in the clinician's pocket. The EHR surfaces the order on the clinician's enrolled phone; the parameters are visible; the clinician presses.
The cryptographic handshake at the pharmacy counter. Two sides, two devices, one agreement. The pharmacist confirms dispensing on their enrolled device; the patient confirms receipt on theirs.
Patient-centric consent for remote chart access. A clinician attempts to open a chart from outside the network, outside standing care-team relationships, outside approved hours, and the access does not proceed. The control plane routes an Explicit-tier push to the patient's own enrolled device: who is requesting, which chart, which clinical context. The chart opens if, and only if, the patient has cryptographically consented, with immediate patient-side revocation and an outbound webhook event.
For AI Agents
The clinical agent can draft. Only the clinician can sign.
Clinical AI is moving from documentation into ordering, and EU AI Act Article 14 makes human oversight of high-risk medical AI a legal requirement, not a policy preference. A logged click is not oversight. A signature is.
The prescriber signs the clinical bounds once
Inside those bounds template-compliant documentation and routine lab orders proceed without paging the clinician.
Outside it, the named prescriber signs
A controlled substance, a high-risk intervention, a record release outside the standing scope: the order stops and surfaces on the licensed clinician's enrolled device with the exact parameters. The agent can prepare and request, only the enrolled human can authorize.
No mandate, no order
If no mandate covers the agent, or the one it names has expired or been revoked, the order does not transmit, and revocation takes effect on the next attempt rather than at the end of a session.
Capability Surface
The primitives under every clinical use case above.
Hash-chained per-actor audit trail
Per actor, through the control plane and the audit export.
Offline-capable signing at the point of care
Once a clinician's device is enrolled, biometric verification and Explicit-tier signing require no network, proofs hold in a durable on-device queue and sync on reconnection. Authoritative-tier orders, including controlled substances, require the synchronous server co-signature by design and are refused rather than queued when the device is offline.
Long-term audit retention
Seven-year cold audit retention is contracted separately, which is the horizon a health system's own record-retention obligations run to.
Regulatory Alignment
What each framework will not let you run without.
DEA EPCS
Two factors of independent categories, biometric enforced at the device secure element. Hash-chained audit trail per prescriber.
HIPAA Security and Privacy Rules
Per-action non-repudiation. Minimum-necessary access supported by patient-consented Explicit-tier gating on remote chart openings.
21 CFR Part 11
Electronic signatures with unique identification, non-repudiation, and trustworthy audit trails.
Alongside Your Stack
Yuthent does not replace your EHR, your internal build, or the pharmacy dispensing system. It is the cryptographic evidence layer beneath all of them: your clinical system continues to own the record, and Yuthent owns the proof.
Deployment Readiness
The deployment ships on one flow: controlled-substance prescribing, two-sided pharmacy dispensing, or patient-consent-gated chart access.
Questions
Answered plainly.
Does Yuthent see patient data or PHI?
No. Biometric matching executes on the acting person's device and never leaves it. The control plane receives action metadata, an order identifier and payload hash, a counter, a device attestation, and the proof, never the chart, the prescription contents, or any PHI beyond what you choose to hash into the signature.
Does Yuthent deploy in the cloud or on-prem?
Hosted multi-tenant on Yuthent's Google Cloud. Because only metadata leaves the device, hosted is sufficient for most health systems. Dedicated cloud and on-prem are available on request and scoped during a deployment.
