| Abstract The research deals with the concept of hiding information in one of the media where the 'Least Significant bit' which is one of the methods of steganography is used. Satellite images were chosen as a means of hiding because they have certain features and characteristics which make them an effective method for hiding. The satellite data have more than one taken image of the same land with different spectra, and each image is called 'band'. Distributing the text on these bands and combining them to form the false colour composite image make the possibility of getting a sequential complete text complex. If hackers could get such images, it would raise suspicion about the area captured by the satellite while this area has nothing to do with required hidden information and transforming them to the second part. The research aims at developing the hiding process by using satellite image features which depend on the method of distributing texts on spectral bands of the satellite image rather than hiding it in one image. | ||
