What is a Digital Receipt?
A digital receipt is a block of data bound together and signed by VeriSign’s timestamping Certification Authority (CS). It includes a fingerprint (hash) of the document file along with the date and time derived from a trusted time source. A digital receipt acts as evidence that a document existed at a particular point in time. It forms the receipt returned to a requesting party to prove the transaction occurred. With VeriSign’s Authentic Document Service, VeriSign acts as witness, standing behind the assertion that the transaction took place at a specific moment in time. Because each receipt is a persistent data object, it can serve as non-repudiable proof of the document’s existence at the time of digital notarization, and of the organization that digitally signed the document.
