Record Integrity Verification
Verify the cryptographic integrity of any AcreSeal record. No login required.
AcreSeal forensic verification lets anyone check a complaint, inspection, or remedial-action record against the digest stored when it was filed. That digest binds the photo, the GPS point, the weather conditions at that moment, and AcreSeal's own server clock, and you can recompute it yourself without access to our internal systems. What the digest does not establish is the time: an independent third-party timestamp covers only those reports a utility has sealed into a work order. Records that have not been sealed say so on their own verification page.
How Verification Works
SHA-256 Environmental Hash
Timestamp, GPS, weather, and photo hash are pipe-delimited and SHA-256 hashed. The raw components are stored so you can recompute independently.
Append-Only Hash Chain
Each audit entry links to the previous via hash. Any modification breaks the chain. Immutability is enforced at the database trigger level.
Photo Integrity
Download the stored evidence photo and run shasum -a 256 on it — the result reproduces the stored-bytes hash published for that record. A camera original will not match: AcreSeal writes provenance EXIF before storing.
AcreSeal does not use a blockchain and does not require proprietary tooling or an account. Every claim on this page is checkable with standard utilities — shasum, exiftool, openssl — and trusted timestamps come from an independent authority we do not control. Step-by-step verification guide.
AcreSeal is an add-on evidence layer: a GPS-tagged photo becomes a sealed record with a tracking link. It complements the work-order, GIS and outage systems a utility already runs, and does not replace them.
