Verify a chain of custody record
Enter the verification code from an Authenticated Chain of Custody Form to confirm its tamper-evident seal is intact. Verification is free, requires no account, and never reveals the contents of the form.
How verification works
When a form is created, CustodyTrack seals it with a hash value — a digital fingerprint of its contents. Every custody event that follows (creation, each transfer) is sealed with its own hash value that incorporates the previous one, forming an immutable chain.
When you verify, we recompute the entire chain and compare it to the sealed record. It works like a tamper-evident seal: if anything changes — a date, a name, a custody event — verification fails.
Only hash values and minimal metadata are checked. The evidence details on the form are never shared through this page.
