– Today Data security is major concern. In this paper, is proposed data hiding (DH) algorithmic rule is projected for digital images. Rather than attempting to keep the PSNR value high, the projected algorithmic rule enhances the contrast of a host image to boost its visual quality. The side info is embedded in conjunction with the message bits into the host image so the initial image is totally retrievable. The proposed the discrete wavelet transforms and discrete cosine transform techniques are used. To our greatest knowledge, it's the primary algorithmic rule that achieves image contrast enhancement by DH(). Moreover, the analysis results show that the visual quality is preserved once a considerable amount of message bits have been embedded into the contrast-enhanced images, even higher than 3 specific MATLAB functions used for image contrast enhancement.
