Veridose · Home Care & Medical
A visit record nobody
could rewrite afterwards.
Veridose seals a home-care or hospice record the moment it is written — signed with the caregiver's own key, hash-linked to the record before it, and timestamped on a public record Authyr does not control. An auditor checks it by mathematics, not by taking the agency's word. It proves what was recorded, and when; it does not watch the visit.
The mandate
EVV is federal law. The tooling is stuck in 2016.
The 21st Century Cures Act requires Medicaid-funded personal-care and home-health visits to be electronically verified — date, location, type of service, the individual served, the caregiver, and the begin and end times.
Today that's served by clunky, GPS-only apps that caregivers learn to game and auditors can't independently trust. A single spoofable location ping is the whole proof.
Veridose does not replace the state's EVV system.It makes the agency's own record provable: each visit and note is sealed as written, chained per patient, and checkable by an auditor without trusting the agency — or Authyr.
How it works
One seal per event, chained per patient.
Signed at writing
The caregiver signs the record with their own key — a passkey on their device, or a key the platform holds for them and labels as such. The label is checkable in the record itself, never silently upgraded.
Chained per patient
Visit start and end, the signed note, certification, face-to-face, addenda and the records request itself — each one hash-linked to the one before. Alter, remove or insert a record and the chain shows exactly where.
Checkable by anyone
Paste a record into the public verifier — no login, no Authyr account. Its SHA-256 fingerprint is folded into an hourly batch timestamped on Bitcoin, so the record can be proven to have existed by that hour and not been rewritten since.
Protects everyone, equally
The same record, whoever is asking.
Agencies
When the records request arrives, the record you hand over can be shown to have existed, as signed, before the letter did — not reconstructed afterwards.
Auditors & payers
A chain they can check themselves, end to end, against a public timestamp — without a site visit and without trusting the agency or Authyr.
Caregivers
A note sealed under their own key is a far better answer in a review than a signature and a recollection.
Where this actually stands
A pilot conversation, not a product you can buy this afternoon.
Built and running
- The seal itself: per-signer keys, two-signer records, self-witness refused in code
- Hospice and home-health record types (visit start/end, signed note, certification, face-to-face, addendum, records request)
- The public verifier at /witness/verify — no account
- Hourly independent timestamp of every stored seal
Not built yet
- A caregiver-facing capture app of our own — today the seal runs inside a partner's charting flow
- Any location or presence measurement beyond what the signing device reports
- State EVV aggregator or payer integrations
- A HIPAA business associate agreement — payloads carry fingerprints and ids, never note text or names
If the problem is real where you work, that is exactly who we want to build the first one with.
