Digitales Unterzeichnen von Vereinbarungen von fernen Knoten aus

摘要

A digital arbitration system comprising a server node and at least one signatory node coupled together through a communication link. Each of the signatory node(s) may be configured with a unique private key which is used to digitally sign a message, a hash value of an electronic document for example, and transmits the digitally signed message being a digital signature to the server node via the communication link. The server node determines whether the digital signatures have been received from at least one of the signatory node(s) and whether each of the digital signatures is valid. The server node then transmits all of the digital signatures to each of the signatory node(s), provided both conditions described have been met.
