Data hiding has drawn increasingly extensive attention recently. Most multimedia data hiding techniques modify and, hence, distort the cover media in order to insert the additional information. Even though the distortion is often small and impe

technique is quite small owing to the low compression ratio. Based on this, a general least significant bit-plane (LSB) embedding technique in the spatial domain was proposed by Celik et al. [6]. The payload and imperceptibility of embedded dat

Nowadays, with the rapid growth in formation technology more and more images and data are available on the internet. So there is a need to provide some kind of authentication to such important data. When the sender transmits the image to the receiver
