摘要：Wet paper coding is a technique that can be used to embed secrets into some specific pixels, called dry pixels, of a digital image. The fully exploiting modifications method (FEM) is a method applied to convey secrets securely from senders to receivers using a stego-image that is slightly modified from the original digital image. Based on FEM, before embedding, we randomly choose pixels in the image to define as wet or dry and treat every pair of two consecutive pixels as a token. If the token consists of at least one dry pixel, it is judged as embeddable; otherwise, it is unembeddable. Experimental results show that our proposed method can achieve very good visual quality and high embedding payload.
