Patent ID: 7142672

Claim:
A method of transmitting sensitive information over a network including the steps of: splitting sensitive information into a plurality of basic elements; generating control information indicative of how to use the basic elements for reconstructing the sensitive information; sending each basic element and the control information from a source computer to at least one corresponding interface computer through an insecure network, forwarding each basic element and the control information from the corresponding at least one interface computer to a target computer through a secure network, and reconstructing the sensitive information in the target computer using the basic elements according to the control information; generating a masked block of information for a basic element of the plurality of basic elements, wherein the step of generating a masked block includes the step of assigning the basic element to a position within a corresponding data frame; inserting noise into the data frame except for the basic element, the noise inserted according to a predetermined algorithm; and inserting the masked block of information and the control information into a corresponding transmission structure for sending the corresponding transmission structure through the insecure network and the secure network, the control information being further indicative of how to extract the basic element from the corresponding masked block of information.
