Patent ID: 8453040

Claim:
A system for obscuring information in messages, comprising: a computer comprising a processor; and instructions which are executable, using the processor, to implement functions comprising: comparing, for an outbound message containing at least one address string that comprises at least a path segment of a Uniform Resource Locator, each of the at least one address string to a compression dictionary to thereby locate any substring within the at least one address string that corresponds to an entry in the compression dictionary; obscuring each of the at least one address string prior to transmission of the outbound message, comprising: replacing, in the each address string, any located substring with the corresponding entry from the compression dictionary, thereby creating a compressed version of the address string; computing an error detection code over the compressed version; concatenating an identifier of the compression dictionary, the error detection code, and the compressed version, thereby creating a concatenated string; and appending an encoding of the concatenated string to location information identifying an intended recipient for information contained within the outbound message, thereby creating an obscured version of the location information in which any replaced substring is recoverable upon subsequently receiving the outbound message as an inbound message; scanning content of the outbound message, prior to the transmission, to locate any form embedded therein as a markup language document; and responsive to locating at least one form by the scanning, obscuring form data within the located form, comprising: removing, from the located form, any hidden input field, each hidden input field specifying at least one parameter, and concatenating each of the at least one parameter to an embedded link of the located form; and performing the comparing and the obscuring for the located form, wherein the location information identifies an intended recipient for information contained in the located form.
