HelloSign creates a comprehensive transaction trail between signing parties. To provide you with a transaction history, we track and timestamp various information from the moment the document is submitted for signature to when it is completely signed and secured, such as IP address.
To ensure that any tampering of your transaction log is detectable, we process the transactions log with hashing technology. Should you ever need to rely on a transaction log, we are right by your side to assist you.
The audit trail that is appended to all executed signature requests includes an identifier that we can use to look up the corresponding transaction log in our database. If you are a HelloSign Business sender, you may separate the audit trail so that it comes back to you as its own file instead of being appended to the signed document.
These records include a hash of the PDF document that we can compare to the hash of a questionable PDF document to determine whether or not it has been modified or tampered with.
Note: self-signed documents (i.e. documents signed using the “Just me” signing option) do not include an audit trail because you are the only signer on the document.
