Reversible data hiding methods can embed secret data into multimedia to prevent attacks from hackers. Reversible data hiding methods based on multiple stego-images have been proposed extensively in recent years. This type of method can embed large amounts of secret bits into several stego-images. However, data embedding may cause serious distortion of(More)
In recent years, the dual stego-image reversible data embedding methods have been developed rapidly, e.g., exploiting modification direction, magic matrix, least significant bit matching, and center folding strategy. The kind of method can effectively embed secret data into two stego-images and maintain excellent image quality and enhance the security. In(More)
