Illustrative scenario, not a customer account.

What a match supports

Your copy matches the recorded file, byte for byte.

Why that matters

A match lets you confirm you’re reading the same version tied to that record. Compare it with proof from the publisher’s official page or another source you trust.

What it doesn’t establish

A match does not prove the research is true or identify its publisher. An edited or re-exported file may not match; no match alone does not prove tampering. A match is still strong, checkable evidence that your copy is the exact recorded version, useful when a report’s contents are disputed.

Check it. Compare it. Keep it.

  1. Check your copy

    Open free Verify and select the report you received. Checking needs no account or credit, and the file stays on your device.

  2. Compare the publisher’s reference

    Compare any matching record with the publisher’s proof from a trusted source. Ask the publisher for the recorded original if you cannot connect the two.

  3. Keep the copy and reference

    Save your copy, the publisher’s proof and the source link together so another reader can repeat the same check.

Keep the rest of the story, too.

Keep the publisher’s source page, version notes, citations and supporting data. A matching file still needs sound methods and evidence behind its claims.

Publishing a report? Record the report itself so readers can check their copies. You can also record a ZIP of supporting data and methods; its proof checks that exact archive, not extracted files.
