Abstract

The principle of hybrid information hiding represented by process of information hiding  message (multimedia files) embedded inside another message which is depended on hiding a certain media in another media using different domains (special domain, frequency domain) to provide protection and security for transformed data,  this paper  suggest an algorithm by using two different files first one compressed binary image, the compression method is run-length and hided this file inside the hostage media by use frequency domain which is represented by Discrete cosine transform (DCT), the second is text ciphered by Caesar method which is depended one secret key by using spatial domain.
The data has been retrieved with no error for both text and binary image after deciphering and decompress process completed; the value of normalization correlation factor for both of them is equal to one.
