Abstract:To ensure the security and anti-disturbing of hiding image information under the conditions of visibility, An image hiding technology based on chaos systems was presented. Firstly, with the Arnold transform and the sequences generated by the chaos system, a hiding image was encrypted; then using Logistic chaos system and image sharing technique to hide the pre-encrypted image. The effect of hiding is also analyzed by using the method of accessing. Simulation results show that the algorithm has good safety and hidden effect.
