Detecting LSB Steganography in Color and Gray-Scale Images
Fridrich J., Goljan M., Du R.
We describe a reliable and accurate method for detecting least significant bit (LSB) nonsequential embedding in digital images. The secret message length is derived by inspecting the lossless capacity in the LSB and shifted LSB plane. An upper bound of 0.005 bits per pixelwas experimentally determined for safe LSB embedding.
