English Abstract
The secure data transmission over internet is achieved using steganography.
It is the art and science of concealing information in unremarkable cover media so as not to arouse an observer's suspicion.
In this research the proposed system is designed to hide video (image, audio) by using discrete cosine transform (DCT) method and discrete wavelet transform (DWT) method and Also, the Principal Components Analysis (PCA) and (DWT) methods were used to hide the data.
After cutting up the video to frames by using Ulead video studio 9 program.
This program have been cutting up video to 20 frame in one second.
The system will embed the (input) secret data (image color ,audio) inside a cover frame, the secret data apply it discrete cosine transformation (DCT) method and the cover frame is decomposing into four parts Horizontally and vertically low pass( LL), Horizontally low pass and vertically high pass(LH), Horizontally high pass and vertically low pass (HL),and Horizontally and vertically high pass (HH ) by using discrete wavelet transformation (DWT) method and the secret data hidden in the part (HH) in segment Least Significant Bit (LSB) of cover image.
and produce (output) stego-image.
The stego key uses for extraction the data hidden (secret data) from stego cover through use the process embedding inverse.
Apply the equation of each Peak Signal to Noise Ratio (PSNR), Mean square error (MSE) and Bit Error Ratio (BER) on image used as a cover before and after the data hiding so that evaluated quality of the image and the quality of effect.
Our proposed system are implement using by MATLAB ver.
7.6 program.
