Based on scrambling and integration of DCT information hiding algorithm

The essay proposes a computing method for information hiding, which is based on the scrambling and blending DCT field digital images. By employing the newly scrambled secret images, this method combines the carrier images with the coefficient matrix of the secret images in the DCT field. In doing so, it can improve the fine unperceptiblity of hiding information as well as increasing the amount of the embedded information.
