An image Encryption Method Based on Bit Plane hiding Technology

引用

Wuhan University Journal of Natural Sciences 2006年第5期11卷 1283-1286页

作者： LIU Bin LI Zhitang TU Hao Network and Computing Center Huazhong Universityof Science and Technology Wuhan 430074 Hubei China

A novel image hiding method based on the correlation analysis of bit plane is described in this paper. Firstly, based on the correlation analysis, different bit plane of a secret image is hided in different bit plane of several different open images. And then a new hiding image is acquired by a nesting ＂Exclusive-OR＂ operation on those images obtained from the first step. At last, by employing image fusion technique, the final hiding result is achieved. The experimental result shows that the method proposed in this paper is effec rive.

In the real-time control of Networked Inverted Pendulum Visual Servo Control Systems（NIPVSCSs）,how to achieve safe and efficient image transmission is an important and challenging ***,the inverted pendulum image is directly transmitted so that the security of images during the network transmission can not be guaranteed in the *** solve this problem,our contributions of the paper include:1) A Chaos-based image hiding（CIH） algorithm to hide the inverted pendulum image is used to improve the security of the image during the network transmission;2)The effectiveness and feasibility of the proposed method is confirmed by simulations and real-time control experiments.
