We propose an effective data hiding method based on the emd embedding scheme proposed by Zhang et al. in order to enhance the embedding capacity. The main idea of our proposed scheme is to convert secret binary messages into a sequence of digits in an 8-ary notational system. Each secret digit is embedded into two cover pixels by modifying the least significant bits (LSBs). As the experimental results show, the embedding bit-rate of our scheme is 1.5 times better than the emd embedding scheme. In a word, we propose a high-quality and high-capacity data hiding method that can ensure the stego-image quality and security.
