Check that a sealed condition report hasn't been changed since it was signed. Everything happens in this browser; your file is never uploaded.
Verification uses your browser's built-in cryptography. Nothing is sent to Meyer App Studio or anyone else.
Each fingerprint is the SHA-256 of the original photo file at the moment it was taken. If you have an original photo, its SHA-256 must match.
| # | Room | Item | Condition | Taken | Location | Source | Fingerprint |

When a WalkProof report is sealed, the app records a SHA-256 fingerprint of every photo, then signs a manifest with the device's private key. The manifest lists the photos, their times, locations, conditions and notes, plus the signatures. A valid result means none of that has changed since sealing.
Compare the signing key shown here with the "Seal" number printed in the PDF footer. Compare the manifest hash with the one in the PDF's Integrity seal section. If both match, the PDF and this file describe the same sealed report.
What it doesn't prove: who was holding the phone, or that a scene wasn't staged before it was photographed. Photo times come from the device. Newer reports also say whether those times were checked against network time when they were taken.
