Methods to dynamically establish overall national security or sensitivity classification for information contained in electronic documents; to provide control for electronic document/information access and cross domain document movement; to establish virtual security perimeters within or among computer networks for electronic documents/information; to enforce physical security perimeters for electronic documents between or among networks by means of a perimeter breach alert system

摘要

The invention is an a document classification and marking engine/method that functions in a real-time compatible mode with off-the-shelf word processors, e-mail programs and presentation or other document development software applications. The software engine is used for the security classification of sensitive or national security classified information in electronic format and is enhanced by methods and processes that ensure that the software classification engine considers all document informational elements regardless of attributes assigned to the text that may hide text from the user. The software engine provides a complete and reliable document classification determination interface method based on user selections and uniquely codes the full text classification determination in a persistent manner within the electronic shell of the document in real-time and dynamically displays the text based full classification determination in the banner of the host document development application. The unique codes of the full classification embedded in the electronic shell of the document enable effective and reliable software processes and methods that establish controls for access, movement, storage etc. for electronic documents, as well as virtual electronic security perimeters, on a computer, networks of computers and/or among computer networks and domains of networks. The full or complete and persistent classification codes embedded in the document shell also enables reliable software processes and methods that immediately warn or alert security personnel of a beach of a physical security perimeter between or among computers networks or domains of networks established to protect the information contained in electronic document format.
