Simple and Secure Digital Color Image Steganography

A simple and secure method of digital color image steganography method will be introduced, the method will hide a digital color image in another image, the covering image will be any type and with any size (the covering image can be smaller than the image to be hidden, thus the capacity of the covering image will be unlimited. The proposed method will apply image resizing, the resizing factors will form the private key to protect the hidden image from being hacked, this key will provide a good key space to secure the image, the extracted image will be very sensitive to the selected values of the private key components. A simple way of image bits hiding and extracting operation will be used, the image bit matrix will converted to one column matrix and embedded in the LSBs of the covering bytes using one assignment operation, the LSBs of the stego bytes will extracted using one operation to create a one column matrix, which will be converted to 8 columns matrix to form the image binary matrix. The method will be implemented and tested using various covering images and various color images to be hidden. The obtained results will be analyzed to prove the quality, speed and sensitivity of the proposed method.
