Abstract: A computer-implemented method for digitally signing an electronic document by a plurality of signers includes determining a signing role of each signer; identifying a to-be-signed portion of the document corresponding to the signing role of each signer; receiving an indication from each signer to digitally sign the document; and applying the digital signature of each signer to the corresponding to-be-signed portion in response to the indication from each signer.

Abstract: A computer-implemented method for digitally signing an electronic document by a plurality of signers includes determining a signing role of each signer; identifying a to-be-signed portion of the document corresponding to the signing role of each signer; receiving an indication from each signer to digitally sign the document; and applying the digital signature of each signer to the corresponding to-be-signed portion in response to the indication from each signer. A computer-implemented method for processing electronic documents includes receiving a document at a document processing station; reading a processing instruction from a processing portion of the document; identifying a processing service within the document processing station for executing the processing instruction; executing the processing instruction at the document processing station using the identified processing service; and applying a digital signature of the document processing station to the document after the processing is executed.

Abstract: Systems and Methods for secured content delivery between a sender and a recipient in an electronic network using PKI-based encryption. The system includes a sender local agent associated with a sender electronic device and a recipient two-factor authentication associated with a recipient wireless device wherein both the devices are capable of connecting to a control server via the Internet. The sender local agent is operable to (i) receive content generated on the sender electronic device, (ii) generate a package of encrypted content using PKI-based encryption by obtaining at least one public key from the control server, and (iii) send the package to the control server. The control server is operable to receive the package from the sender local agent and transmit the package to the recipient local agent.
