How can I prove the validity of a document timestamped by Universign?

Universign uses the timestamp protocol defined by the IETF RFC 3161 standard. You can use any software compliant with this standard to check your timestamp seal. Of course, you can also use our service by loading a document that has already been timestamped using the timestamping web interface. If the document was correctly timestamped, the status bar will display the message “Intact” along with the date and time of the timestamp.
