Phase 2 update
Phase 2 announced for Oct 2026: see what changes.
How this works
When an evidence pack is exported, the service records an audit entry with the pack's fingerprint, template, and generation time. This page checks a fingerprint against those generation records. If a pack you hold has been altered since export, its recomputed fingerprint will no longer match a recorded generation.
A match confirms only that this fingerprint corresponds to a pack generation recorded by this service. It does not verify who holds the pack, the accuracy of its contents, or any legal, regulatory, or compliance outcome.
