In the daily life, secret data delivery is an important application for privately communicated to each other over computer networks. Data hiding technique is a good way to achieve the secret data delivery, thus the color image is a popular cover media used to send the secret. Block truncation coding (BTC) is a lossy image compression technique, which can significantly reduce the size of image. In this paper, a novel data hiding method is proposed to conceal secret data into color BTC compression code. To compare with Chang et al.'s method, the proposed method can effectively generate common bitmap for save the size of compressed image. Furthermore, the proposed method can conceal more than four secret bits into a block in average. From experimental results, the proposed method not only successful achieves the goal of secret data delivery but also significantly reduce the computation cost of common bitmap generation.
