This paper proposes a quantization-based steganography method of extracting hidden data without any reference images or memorization of positions, into which data are embedded. Since the proposed method offers the user the flexibility of choosing data hiding positions, it enables the user to select positions for embedding data on an individual image basis and/or the basis of the coding scheme being applied to the images. Simulation results show the effectiveness of this method.
