Abstract EN
This research includes building a system to hide an image file within the image file (cover) to produce material hidden file, which does not contain misrepresentation or distortion ,can human vision system palpation or note any difference between the cover and the article hidden file output.
Where the system consists of two main phases:- In the first stage was compression secret color image is using a technique of compression so as to reduce the size of the image data to wanted hiding and which features large , compression technology consists of three basic components: - The application of the discrete wavelet transform.
The scalar quantization, means to reduce the number of bits in the one-pixel.
Use at this stage to Run-Length Encoding (RLE).
Where the use of hybridization in the compression process the hybrid technology merged between discrete wavelet transform and scalar quantization, entropy encoding to obtain the proportion of high compression of the image and this is proven by experiments.
In the second phase of the system method was used to hide compression image, which we get from the first phase, where method of information hide in the spatial domain.
Main idea the use of threshold mechanism to determine important information in the secret image of and that is hidden within the color image used as a cover so that the change is performed on the image used cover can not be to the human eye detect any choose the threshold so that the appropriate system with the human eye, where they are converted first a ll information compression and is used as a cover to bits, then do the process of replacing the information that was determined using the threshold and which are the sites most important (Most significant bits (MSBs)) of the secret image to be concealed in the less important Least significant bits(LSBs) of stego image the proposed system provides high security so that it is difficult to detect the presence of the hidden image
