Every claim photo, provably real.
Attest signs media on the capture device, scores each asset’s provenance risk with named factors, and routes suspect claims to SIU before they pay out.
Three claims, live in the sandbox
Two attested photos. Signatures valid, device enrolled, GPS present. Risk 0, auto-approved.
Two un-attested web uploads (device_not_enrolled + gps_absent) plus one attested asset. Routed to adjuster review.
Tampered manifests: signature_invalid +70 and sensor_hash_mismatch +50. Risk 100, escalated to SIU.
Live video inspection sessions
For real-time inspections, each chunk of the recording is hashed into a chain seeded by a nonce the server issues when the session opens, so a pre-recorded feed can’t pass. Altering, dropping or reordering a chunk breaks every hash after it.

}Screen media captured outside the SDK
Legacy uploads can be screened by an external AI-image detector (Sightengine). The screening score is reported next to the cryptographic risk score and kept separate from it.
SIU escalation & evidentiary PDF
One click generates a single-page evidentiary report with claim metadata, the risk-factor breakdown, the chain-of-custody timeline and device details. The adjuster makes the call.
