US Patent Issued to UNIVERSITY OF GEORGIA RESEARCH FOUNDATION on March 17 for "RF steganography based on photonics" (Georgia Inventors)

ALEXANDRIA, Va., March 17 -- United States Patent no. 12,580,656, issued on March 17, was assigned to UNIVERSITY OF GEORGIA RESEARCH FOUNDATION INC. (Athens, Ga.).

"RF steganography based on photonics" was invented by Mable P. Fok (Bishop, Ga.) and Qidi Liu (Athens, Ga.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Various examples are provided related to single channel and multi-channel radio frequency (RF) steganography. In one example, a method includes generating an amplified spontaneous emission (ASE) broadband signal; spectrally slicing the ASE broadband light to achieve taps for generating a dynamic photonic finite impulse response in an RF domain; generating a stealth-modulated broadband optical car...
