System and user interface supporting URL processing and concurrent application operation

A system employed by an application for encoding URL link data for use in detecting unauthorized URL modification, comprising:

• a link processor for processing URL data by
• identifying an address portion of said URL
• encrypting said address portion of said URL,
• incorporating said encrypted address portion of said URL, together with said address portion of said URL in non-encrypted form and a session identifier identifying a user session of computer operation, into a single processed URL data string;
• and
• a communication processor for incorporating said processed URL data string into formatted data for communication to a request device.

A system employed by an application for decoding URL link data encoded for use in detecting unauthorized URL modification, comprising:

• an input processor for receiving an encoded URL;
• a link processor for processing said encoded URL by
• identifying an encrypted address portion of said received encoded URL and a corresponding non-encrypted address portion of said received encoded URL,
• decrypting said encrypted address portion of said URL to provide a decrypted URL address portion,
• a validation processor for determining if said decrypted URL address portion has been subject to unauthorized modification by determining if said decrypted URL address portion is different to said corresponding non-encrypted address portion of said received encoded URL.

A method employed by an application for encoding URL link data for use in detecting unauthorized URL modification, comprising the steps of:

• identifying an address portion of a URL;
• encrypting said address portion of said URL;
• incorporating, said encrypted address portion of said URL, together with said address portion of said URL in non-encrypted form, into a single processed URL data string;
• providing a key supporting decryption of said encrypted address portion to a destination system;
• and
• incorporating said processed URL data string into formatted data for communication to said destination system.
