摘要：In this paper, we present a novel Steganography method for embedding of secret data in still grayscaleimage. In order to provide large capacity of the secret data while maintaining good visual quality of stego-image, theembedding process is performed in transform domain of Discrete Wavelet transform (DWT) by modifying of transformcoefficients in an appropriate manner. In addition, the proposed method do not require original image for successfulextraction of the secret information. The experimental results show that the proposed method provides good capacityand excellent image quality.
