Some embodiments include a privacy/security apparatus for a portable communication device that includes a housing assembly configured to at least partially attenuate at least one of sound energy, acoustic energy, and electromagnetic energy including light, optical, and IR energy and RF radiation from passing through the housing assembly. The housing assembly includes a Faraday cage with two or more portions, and at least one protective shell coupled to or forming at least one aperture. The at least one aperture is configured and arranged to at least partially enclose the portable communication device so that at least a portion of the portable communication device is positioned within at least one portion of the Faraday cage, and the at least one seal coupled or integrated with the protective shell. The housing assembly can be an articulating assembly, a sliding assembly, and can include an active acoustic jamming or passive acoustic attenuation element.

The invention claimed is: 1. A privacy/security apparatus for a portable communication device comprising: a housing assembly configured to at least partially attenuate at least one of sound energy, acoustic energy, and electromagnetic energy including light, optical, and IR energy and RF radiation from passing through the housing assembly, the housing assembly including: a Faraday cage comprising two or more portions, and at least one protective shell coupled to or forming at least one aperture, the at least one aperture configured and arranged to at least partially enclose the portable communication device, wherein the at least one protective shell comprises at least a portion of the Faraday cage enabling at least a portion of the portable communication device to be positioned on or adjacent the Faraday cage; at least one seal coupled or integrated with the protective shell; a seed source or seed generator, the seed source or seed generator configured to generate at least one random seed; at least one speaker or noise generator configured and arranged to generate acoustic jamming noise, the acoustic jamming noise comprising at least one audio jamming signal; a controller circuit coupled to the at least one speaker or noise generator, the controller circuit configured and arranged to generate the acoustic lamming noise sound from the at least one speaker or noise generator based at least in part on at least one user selectable privacy setting and the at least one random seed. 2. The privacy/security apparatus of claim 1 , wherein the housing assembly includes an articulating assembly configured and arranged to articulate a portion of the housing assembly to one or more positions to enable a user to insert or enclose and remove the portable communication device. 3. The privacy/security apparatus of claim 1 , wherein the housing assembly includes a sliding assembly configured and arranged to slide a portion of the housing assembly to one or more positions to enable a user to insert, enclose or remove the portable communication device. 4. The privacy/security apparatus of claim 1 , wherein the at least one speaker or noise generator is coupled to the at least one seal and an active acoustic jamming system, and the active acoustic system is activated by the controller circuit. 5. The privacy/security apparatus of claim 1 , wherein the housing assembly is configured and arranged to be movable between an open and a closed position to enable a user to insert or enclose and remove the portable communication device. 6. The privacy/security apparatus of claim 1 , wherein the housing assembly comprises a sheath. 7. The privacy/security apparatus of claim 1 , wherein the housing assembly comprises a hood assembly and a base assembly, the base assembly including a Faraday base assembly forming at least one of the portions of the Faraday cage. 8. The privacy/security apparatus of claim 7 , wherein the hood assembly is configured and arranged to enable and disable a plurality of the portable communication device's microphones and/or cameras from receiving unjammed or unblocked audio and light energy in a single motion. 9. The privacy/security apparatus of claim 7 , wherein the hood assembly is configured and arranged to reversibly apply at least one audio jammer to reversibly enable and disable at least one microphone of the portable communication device from receiving unjammed audio energy. 10. The privacy/security apparatus of claim 7 , wherein the hood assembly is configured and arranged to reversibly apply at least one element to reversibly cover and uncover at least one camera of the portable communication device. 11. The privacy/security apparatus of claim 7 , wherein the at least one seal comprises a seal configured and arranged to cover at least one microphone of the portable communication device irrespective of the position or movement of the hood assembly on the housing assembly. 12. The privacy/security apparatus of claim 1 , wherein the at least one seal comprises an environmental seal. 13. The privacy/security apparatus of claim 1 , wherein the at least one seal comprises an RF attenuation or absorbing seal. 14. The privacy/security apparatus of claim 1 , wherein the at least one seal comprises at least one of a magnetic seal, an electromagnetic seal, an acoustic attenuation seal, and an optical seal. 15. The privacy/security apparatus of claim 1 , wherein the at least one seal comprises a fingerstock element. 16. The privacy/security apparatus of claim 15 , wherein the seal includes at least one elastomeric element positioned adjacent to the fingerstock. 17. The privacy/security apparatus of claim 16 , wherein the at least one elastomeric element is positioned within at least a portion of the fingerstock. 18. The privacy/security apparatus of claim 1 , wherein the housing assembly includes at least one port configured to couple with the portable communication device. 19. The privacy/security apparatus of claim 18 , wherein the at least one port comprises at least one of a sound transfer port, an RF transfer port, a data transfer port, a power transfer port, and an optical port. 20. The privacy/security apparatus of claim 1 , wherein the at least one protective shell includes a decorative layer or region. 21. The privacy/security apparatus of claim 20 , wherein the decorative layer or region comprises at least one of a patterned surface, a window, a display, an emblem, and a logo. 22. The privacy/security apparatus of claim 1 , wherein the controller circuit is configured and arranged to modulate at least one privacy/security setting selected by a user. 23. The privacy/security apparatus of claim 22 , wherein the at least one privacy/security setting includes a setting that is configured and arranged to alter the magnitude of energy reaching the portable communication device through the housing assembly. 24. The privacy/security apparatus of claim 23 , wherein the energy comprises at least one of sound energy, RF energy, electrical energy, electromagnetic energy, and optical and/or IR energy. 25. The privacy/security apparatus of claim 1 , wherein the housing assembly includes at least one microphone. 26.
