Digital image scrambling is one of the most important methods of imageinformation hiding and camouflage. A new digital image scrambling algorithmbased on chaos in low intensity laser-DNA molecule systems is presented in thispaper for image encryption. Firstly, the chaotic sequence is generated by lowintensity laser-DNA molecule system,. Not only is the generated, chaoticsequence extremely sensitive for initial value, ergodic and aperiodic, but alsoit has higher security than the one generated by Logistic Mapping. Based, on thechaotic sequence(s), the image is confused by all pixels encryption and theimage ranks com, pound, encryption. Simulation experimental result shows thatthis method has good scrambling performance, security and robustness. ICIC International ? 2009.
