Your health record is the most sensitive data you own. Livaramed's architecture assumes that, at every layer — encryption at the field level, keys derived per patient, and de-identification before any data crosses a provider boundary.
Protected health information is encrypted at the individual field level — roughly forty fields across seventeen data models, from chat messages to medication names to analysis results. Not just "encrypted at rest" as a disk checkbox: each sensitive value is individually sealed with authenticated encryption.
Every patient's data is encrypted with a unique key derived via HKDF-SHA256 from a master key that never leaves the server. Compromising one record cannot unlock another patient's data. The master-key layer supports hardware KMS providers (AWS KMS, Google Cloud KMS).
Before any case data is sent to a second AI provider for adversarial review, all 18 HIPAA Safe Harbor identifier categories are stripped: names anonymized, dates shifted while preserving relative timelines, contacts redacted. The re-identification map exists only on our server and is destroyed — with cryptographic memory zeroing — the moment the pipeline completes.
Access to records, administrative actions, emergency events, and safety interventions are written to an audit log with an independent filesystem fallback — so the trail survives even a database outage.
Emergency access to an incapacitated patient's data requires five sequential gates: administrator authentication, password re-confirmation, a written justification, an active-session uniqueness check, and a strictly time-bounded session — with per-record access counting, automatic expiration, patient notification, and an immutable audit trail.
Nightly automated backups of both the database and patient knowledge stores to offsite storage, plus an independently escrowed encryption key — because data protection includes surviving disasters, not just attackers.
Your data is never sold. It is never shared with third parties for marketing. It is never used to train AI models. Patient-facing AI calls run under enterprise API terms, and every cross-provider transmission is de-identified first. You can export your record, share it with your doctor through expiring, password-protectable links you control — and it remains yours.
Livaramed's architecture is built to HIPAA-grade standards — field-level encryption, Safe Harbor de-identification, audit trails, and access controls. Formal compliance attestations and business-associate agreements are part of our commercial rollout for healthcare organizations; enterprise buyers can request our current compliance documentation at support@livaramed.com.
