A PROPOSED SYSTEM TO HIDE INFORMATION BASED FOUR ALGORITHMS FOR IMAGE STEGANOGRAPHY

Abstract

Nowadays, protecting important information, such as images, audio and video files, has become a matter
and must be protected from hacking because the circulation of this information takes place through
unsecured communication channels. Scientists have discovered many of these techniques to protect
information, such as: cryptography and steganography. In this research, a proposed system to hide
information based four algorithms for image steganography. The first step using AES modified
algorithm, while in the second step using RSA modified algorithm to increase the complexity and high
security. The third step fuzzy stream algorithm was used to increase the complexity and eliminate on the
non-linearity of the encrypted information. Third step apply LSB technique was used, which is the
technique of hiding the information. This system provides a high ability to include information and an
inability to perceive hidden information through the use of a many of indicators and PSNR, MSE and
SSIM and that were characterized by high and good rates with modern hiding techniques.
