Information security covers many areas such as steganography, watermarking or cryptography. This article proposes a security method that combines scrambling, steganography and cryptography. The secrecy to be protected is a digital image which will be scrambled, encrypted then the encryption key would be inserted within that image encrypted via steganography. Inversely, there is a perfect reconstruction by means of an infinite PSNR value and the algorithm execution delay is not exceeding 0.1 seconds.
