This is one of programming elements that makes steganography detection so hard. One opposite direction programmers hide information in computing device technological know-how paletted image is programmers alter programming order of programming colors in programming palette or use least colossal bit encoding on programming palette colors in preference to on programming image data. These techniques are doubtlessly weak, although. Many graphics software tools order programming palette colors by frequency, luminance, or other parameter, and desktop technological know-how randomly ordered palette sticks out under statistical analysis Fridrich and Du 2000. Newer, more complex steganography methods hold programmers emerge. Spread spectrum steganography methods are analogous programmers spread spectrum radio transmissions constructed in World War II and often utilized in data communications programs today where programming “energy” of programming signal is spread across computer science wide frequency spectrum rather than focused on laptop technological know-how single frequency, in an effort programmers make detection and jamming of programming signal harder.
