This subject has led to design some effective algorithms for the processing of colored images such as coloring, changing the color, compressing and Steganography. LSB is considered one of the oldest methods in secret information Steganography in images. There have been some various designs for this method. Using a compound method can lead to some new algorithms. This paper presents a new method for secret information Steganography.
