Abstract
The present invention provides an apparatus and method for confirming, timestamping, and archiving documents using telecopiers (e.g., facsimile machines). A user sends a document to a timestamping service via facsimile, which archives the transmission with a timestamp. A submission receipt, containing size-reduced images of the submission and a document identification value (DIV), is prepared and sent to the sender. The DIV can later be submitted to the timestamping service to obtain verification that the document was received at the indicated time. In addition, the invention allows for various other forms of document transmission, document identification, and timestamp verification. The invention is thus useful in any situation where it is desired to prove that a document was in existence at a given time. Other embodiments of the invention provide senders of facsimile and telecopier transmissions with confirmation that their transmissions were received successfully.
