Every photo and video captured through FieldReel is SHA-256 hashed and Ed25519-signed at the moment of upload, RFC 3161 timestamped, and packaged into a downloadable Certificate of Authenticity.
FieldReel keeps the receipt. You keep the document. Anyone can verify it here.

TOS §6B
Drop a certificate PDF, a photo, or paste a SHA-256. We compute the hash in your browser, then check the public registry. No account. No telemetry. No bytes leave your device.
No account required. We hash the file in your browser before lookup — your file never leaves your device unprocessed.

Every primitive is a published, open standard. No proprietary cryptography, no black boxes. A holder can verify any FieldReel certificate using OpenSSL alone.
Technician shoots through FieldReel. Device timestamp, GPS, camera make/model travel inside the file.
Server computes SHA-256 of the original bytes BEFORE compression and again of the stored WebP. Both digests written to an append-only photo_evidence row.
On submit, every evidentiary field is canonicalized into JSON and each photo digest is embedded. The snapshot becomes the chain-of-custody anchor.
Snapshot is signed with FieldReel's Ed25519 evidence key. The public key is published on this page so any third party can verify offline.
Manifest hash is sent to a public RFC 3161 trusted timestamp authority. Token proves the manifest existed at a specific UTC time, independent of FieldReel.
Multi-page PDF containing manifest, signature, public-key SPKI PEM, TSA token, and a QR code linking back here for verification.
Sent to the recipients you choose (owner / tech / customer) and downloaded to your device. FieldReel does not retain the PDF — only the receipt.
Drop the file or paste its hash. Browser hashes locally, calls our public registry, reports whether the document matches a record FieldReel issued.
Most platforms hoard your data. That makes them the custodian of every dispute, every subpoena, every breach. FieldReel inverts the model: we issue a tamper-evident record at capture, hand the document to you, and keep only the cryptographic receipt.
Yours forever, regardless of what happens to FieldReel.

Admissibility is a judicial determination, not something any platform can guarantee. FieldReel is engineered to support self-authentication standards under U.S. Federal Rules of Evidence 902(13) and 902(14) (electronic-record certification, hash-authenticated digital data) and the integrity-presumption framework in section 31.3 of the Canada Evidence Act. Whether a specific judge admits a specific certificate depends on the matter; ask qualified counsel.
Nothing on this page is legal advice. Final TOS, marketing copy, and litigation positions should be cleared by counsel admitted in your operating jurisdictions.
FieldReel turns the daily field-service workflow into a pipeline of tamper-evident evidence — without changing how your techs work.
