  This paper is concerned with secret hiding in multiple image bitplanes for
increased security without undermining capacity. A secure steganographic
algorithm based on bitplanes index manipulation is proposed. The index
manipulation is confined to the first two Least Significant Bits of the cover
image. The proposed algorithm has the property of un-detectability with respect
to stego quality and payload capacity. Experimental results demonstrate that
the proposed technique is secure against statistical attacks such as pair of
value (PoV), Weighted Stego steganalyser (WS), and Multi Bitplane Weighted
Stego steganalyser (MLSB-WS).
