lgorithm (2) The Proposed Hiding Algorithm. Inputs: RGB image, secret message and the password. Output: Stego image.
Begin
scan the image row by row and encode it in binary.
encode the secret message in binary.
check the size of the image and the size of the secret message. start sub-iteration 1:
choose one pixel of the image randomly
divide the image into three parts (Red, Green and Blue parts)
hide two by two bits of the secret message in each part of the pixel
by searching about the identical.
if the identical is satisfied then set the image with the new values.
otherwise hide in the two least significant bits and set the image with the new values
save the location of the hiding bits in binary table. end sub-iteration 1.
set the image with the new values and save it. End
