A spatial domain steganographic scheme for reducing embedding noise

In this paper, a new spatial domain block based encoding method is proposed which adds less noise during embedding. Proposed block based encoding scheme uses Single Digit Sum Encoding and Matrix Encoding to improve the embedding efficiency. We show analytically that the amount of additive noise due to embedding for the proposed scheme is less than both LSB matching in single bitplane and LSB replacement in multiple bit planes. Experimental results reveal that the proposed scheme shows better performance against Wavelet Absolute Moment Steganalyzer than LSB with single plane and LSB with multiple planes.
