Steganography is the art of the dissimulation of a secret message in a cover medium such that the resultant medium (stego) is almost identical to the cover medium. Nowadays, with the globalization of the exchanges (Internet, messaging and e-commerce), using diverse mediums (sound, embellish with images, video), modern steganography is widely expanded. In this manuscript, we studied adaptive LSB methods of stéganography in spatial domain and frequency domain (DCT, and DWT), allowing of hiding the maximum of useful information in a cover image, such that the existence of the secret message in the stégo image is imperceptible and practically undetectable. Security of the message contents, in the case of its detection by an opponent, is not rea...
