Checking whether a file is a genuine PDF file

[Michele (Mike) Hjorleifsson]

what about using a digital signature ? the current PDF standards and even ODF standards support a digital signature that would ensure the file hasnt been tampered with since it was signed. Though i guess you could create a garbage PDF and sign it if you wanted.
