A steganography project using the least significant bit method.
This method encodes the message in the least siginificant bit of each “word” of the file. In the case of images, this “word” is each R,G and B value of each pixel. Therefore, the capacity of a photo is more or less (3*M*N)/8, being N and M the pixels per row and per column of the photo.
In order to make the steganographied image indistinguishible from an original one (without having access to the original), the hidden message is encrypted using AES-256 and a given password. Thus, the analysis of the least significant bits of each word may not yield any result on whether it contains a secret message or not.
