How does it work in Jpeg-domain? With which steganography algorithm?

I use Y′CBCR representation of the colors, and hide message with LSB on Y'. This 16 pixels by 16 pixels in order to keep information after JPEG compression.

why should use compact luminance? How does it work?(ycbcr->setY((double)(k + (ycbcr->y() * (128-k)/128.0) ));)
