The technique of information hiding is booming in recent decades. There have been considerably explored in the spatial domain and frequency domain of information hiding researches. In this paper, we propose a information hiding scheme in frequency domain for color images, where the image quality is obviously enhanced as well as the higher capacity is still guaranteed. In our scheme, we use the color images as cover images. Due to the color space conversion, the secret data will be embedded into the subspace v2 of the cover images and the performance of our system will be verified. We can reconstruct the original images by disguised v2 cover media. When the receiver receives the images, they can adopt the opposite way of embedding to extract the secret data and also reconstruct the original color images without distortion. The experimental results show that, comparing the current color image hiding technology, our proposed scheme provides higher hiding capacity and better quality of the image for another research or application.
