Stenography is the science that ensures secret communication through multimedia carriers such as image, audio, and video files. The ultimate end of stenography is to hide the secret data in the carrier file so that they are not detected. To that end, stenography applications should have such features as undetectability; robustness; resistance to various images process, sing methods, and compression; and capacity of the hidden data. At the same time, those features distinguish stenography applications from watermarking and cryptography applications. This study is different from other studies in the literature in that the undetectability parameter has been achieved through hiding data in line with the human sight system. In that sense, it has been determined through using the visible light wavelength limits of the pixel-carrying file in which the data are to be hidden. The peak signal-to-noise ratio has been used to evaluate the detectability and quality of the stego-image in which the secret information is embedded as a result of the data embedding process.
