ABSTRACT:
An electronic signature program to create an electronic signature for documents, filings, and transactions records effectuated between computers. A computer user is authenticated by a server computer. The computer user supplies certain information to the server computer, which extracts the information, and when a signature command is received, combines certain of the user submitted information with certain predetermined elements of the system information of the server, then digitally signs this combination of information along with the document, filing or transaction record which is being signed. The digitally signed combined information is returned to the user as the user's electronic signature of the information which was submitted for signature, together with the signed information, being the document, filing, or transaction record itself.
