In this paper, we transmit an encrypted secret image, where an image is used as medium to
hide the encrypted secret image, called cover image. So, we have first encrypted a secret image
by using Integer Wavelet Transform (IWT), then the secret image is scrambled by Arnold
transform and xored operation with a two-type of chaotic map key to protect a cipher image
and enhance the security. This proposed technique can achieve the perfect reversibility that is
image recovery and data extraction are free of any error. In steganography stage, we have used
the least significant bit (LSB) method to hide the three planes of the encrypted color image into
true image. A modified scanning ordering is used, and IWT in each block divides into the hiding
image.
