JPEG Image Information Hiding Algorithm Based on Intelligent Agent Adaptive Block

Abstract

After analyzing and exploring a variety of image information hiding algorithms, this paper proposes a method based on intelligent multi-agent system to segment wavelet blocks adaptively according to different textures. This method can automatically adjust the embedding intensity of hidden information according to the difference of visibility JND and ensure the original image. Chip quality, and the use of chaotic sequence algorithm to properly encrypt the hidden information, so that the hidden information has better security, the design of information embedding and extraction algorithm, and on the platform of MATLAB to achieve. Simulation results show that this method not only maintains the high visual quality of JPEG images, but also has a high capacity of information hiding, which provides security for real-time image communication in the Internet environment.
