On-device hashing
Chunk hashes and Merkle roots cover the captured bytes to make tampering detectable.
Epistemic Recorder
Capture that proves itself.
Recorder is designed for high-trust capture across rigs: Android and iOS apps, plus the Epistemic Universal Box (EUB) for external camera workflows. It computes hashes and Merkle roots, signs canonical manifests with hardware-backed keys, and embeds provenance directly in the file for downstream verification.
EUB works like a standard touchscreen external recorder (think Atomos Ninja), but generates the same proofs as the apps and can connect directly to the Epistemic Vault.
iOS — Coming soon
Recorder signals
Hash → Manifest → Attestation
Integrity and provenance are created at the source, not added later.
Built for verification from day one.
Lightweight capture UX with heavy-weight guarantees.
Signed manifests
Canonical CBOR payloads wrapped in COSE signatures for portable verification.
Randomized sensor challenges
During capture, Recorder issues randomized challenges that can be corroborated in verification and forensics.
Trust tiers
Attestation + host integrity signals summarize capture conditions (e.g., device integrity).
Choose your capture rig.
Same proof model, different form factors.
Mobile
Android & iOS apps
Capture in the field with device-backed keys and embedded provenance.
Hardware
Epistemic Universal Box (EUB)
A dedicated touchscreen recorder for external cameras—same proofs as the apps.
Workflow
Direct Vault connection
Upload to Vault with proofs intact for zero-trust ingestion and receipts.
Recorder in the field.
Designed to move with your team without breaking flow.
01
Capture
Record on Android/iOS, or via EUB with external cameras and pro monitoring workflows.
02
Embed
Manifests are signed and embedded inline (no fragile sidecars required).
03
Hand off
Connect directly to Vault (or any verifier) to independently recompute and validate proofs.
Trust layer
Proof carries into the Vault.
Recorder is built so Vault can re-verify every byte at ingestion and issue a signed receipt.
Portable
Verification works wherever the file goes.
Explicit
Trust conditions are encoded, not implied.
Defensible
Preserve provenance across edits and distribution.
