Why is timestamping important for PDFs?

Timestamping provides proof that a document existed at a specific time, helping with legal compliance, document integrity, and verification of authenticity.

How does a PDF timestamp differ from a digital signature?

A timestamp verifies when a document was created or modified, while a digital signature verifies the identity of the signer and ensures the document hasn’t been altered.

Is the timestamp legally recognized?

Yes, timestamps generated using trusted authorities comply with international standards, making them legally valid in many industries and regions.

Does timestamping prevent a document from being modified?

While it does not prevent modifications, it ensures that any changes made after the timestamp will invalidate the original verification, highlighting potential alterations.
