Record Integrity Verification
Verify the cryptographic integrity of any AcreSeal record. No login required.
AcreSeal forensic verification lets anyone independently confirm that a complaint, inspection, or remedial-action record has not been modified since it was sealed. Every record is bound to a SHA-256 hash chain incorporating GPS coordinates, timestamps, photo evidence, and environmental conditions. If any element changes after sealing, the chain breaks — detectable without access to AcreSeal's internal systems.
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.
No blockchain, no proprietary tooling, no account required. 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.
