Newly developed optical communication surveillance technologies provide both direct coupled and proximity tapping of fiber optic networks, without breaking or disrupting the optical characteristics of the media itself, resulting in virtually undetectable surveillance of the optical communication in progress. phoenix digital has developed new optical technologies capable of optical communication fault prediction and dimensional fault isolation. During the course of these developments, a new technique for providing on-line, continuous, real time optical data protection, with optical tap detection and on-line dimensional tap isolation, was uncovered. This technical data protection, and on-line backscatter signature analysis of the data transmissions for optical tap detection. Through on-line comparison of the optical data backscatter signature to a predefined signature reference (developed through mathematical modeling) low level signature discontinuities (FRESNEL) resulting from optical tap instrusions can be detected. During Phase I of this project a functional design methodology will be developed for a universal communication device (tempest design) capable of physical layer portability into existing communication systems for ultra-secure communication, with on-line optical data protection, surveillance monitoring, and real time intruder detection and location capability.
