Chen Yuefen, Junhuan Lin, Zhang Shiqing, Caiming Chen · 2010
This paper introduces the principle of image scrambling and information hiding, and proposes a double random scrambling based on image blocks. The image information hiding and extraction system is implemented using Matlab, and its resistance to cropping and scribbling is analyzed. The proposed algorithm has the advantages of high efficiency and simple implementation.
