  • Patent number: 6796489
    Abstract: Systems and methods for processing or recording electronic documents that have embedded digital signatures. In an electronic document, signature blocks are used to embed the digital signatures. When an electronic document is received for recordation, the schema and profile of the document are checked. The electronic document or digital signatures are validated by reconstructing the document to a previous state such that the digital signature may be validated. The electronic document is processed and endorsed by inserting endorsement data. The electronic document is digitally signed by the recorder and a receipt is also digitally signed by the recorder. The electronic document is then imaged and indexed. The recorded electronic document and the receipt are returned to the sender using routing information that was included in the electronic document.

  • Publication number: 20020019937
    Abstract: Transport software is provided which facilitates secure transfer of legally enforceable electronic documents between servers in a computer network. The transport software includes four scripts. A doc.send script at the originating server causes preparation of a package having an electronic document and routing information, and transfers the package to the destination server. Consistent with a doc.receive script, the destination server performs an initial validation of the package and, if validation is successful, processes the electronic document. The electronic document is then returned to the originating server in accordance with a doc.return script, and received and processed at the originating server consistent with another doc.receive script. If the electronic document does not pass the initial validation, it is returned to the originating server in accordance with the doc.receive script at the destination server and received and processed at the originating server consistent with the doc.
