Abstract
A system and apparatus facilitates digital signing of data communicated between a first unit and a second unit through an interface independent proxy, or multiple independent proxies, interposed between the first and second units. The independent proxy has a digital signature initiation data detector to detect embedded signature initiation data in data to be signed. The independent proxy contains a signature generator through which the form based communication data flows. Initiation data is used in the communication data to automatically trigger the intermediary or independent proxy to sign the communication data. The signature generated by the intermediary is a persistent signature which is preserved in memory so that later verification can be performed once a transaction has been completed.
