PDF Authenticity Check
Runs the same category of forensic checks as a PDF reader's document-integrity panel: how many times the file has been incrementally saved since its first version, whether it carries a real cryptographic digital signature field, and its embedded metadata (author, producer, creation/modification dates). Also checks for a The Paper Room signature certificate if present. This does not perform full PKI certificate-chain validation — for legal certainty on a digitally-signed document, verify it in Adobe Acrobat or a dedicated signature validator.

Frequently asked questions
What does the PDF authenticity check look for?▼
It examines the document's internal structure: incremental save count (how many times it was modified), embedded digital signature fields, metadata (author, producer, creation and modification dates), and whether a Paper Room signature certificate is present.
Can it detect if a PDF has been tampered with?▼
It can identify signs consistent with modification — such as multiple incremental saves or mismatched creation/modification dates — but it cannot definitively prove tampering. For legal certainty, verify in Adobe Acrobat or a certified validator.
Does this replace a full digital signature verification?▼
No. This is a structural inspection tool. It tells you what the file claims about itself. Full PKI certificate-chain validation requires a dedicated signature validator like Adobe Acrobat or a qualified trust service.
