A Study of Robust Steganography on Red Component by Using DWTDCT Transform

Abstract

In this paper, we suggested a resilient approach for the steganography on the red section using the two different algorithm such as the discrete wavelet transformand discrete cosine transform algorithm (DWTDCT). Hybrid DCT-DWT Digital picture steganography method is presented by the proposed algorithm. We put much effort into the red component. We put a lot of effort into developing two mechanisms: the first one, called DWT, and the second one, called DCT. Studying the relevant research literature for a variety of evaluation parameters. For example, increasing capacity typically results in a decrease in the robustness or imperceptibility of the steganography. The practice of steganography is concealing sensitive data by encoding it in a cover file that may take the shape of text, images, audio, or video in such a way that it cannot be deciphered by anybody who is not privy to the information. The success of the suggested method is shown by the study of the results on the steganography's predetermined parameters, which validates the use of the method. The DWT and DCT procedures, when combined, provide benefits that are superior than those offered by either approach used alone. Research challenges in image steganography include increasing effectivenessrobust steganography on red component by using DWTDCT transform.
