A SDS Based Steganographic Scheme for Reducing Embedding Noise

In this paper, a new spatial domain encoding method is proposed to reduce the amount of noise added during embedding. Proposed block based scheme uses single digit sum encoding to improve the embedding efficiency. The method is especially suitable when more than two bit planes are used for embedding. Experimental results reveal that the proposed scheme gives better performance against wavelet absolute moment steganalyzer than existing spatial domain schemes like multiple bit plane LSB embedding.
