The ever-increasing development of telecommunications has made secure transmission one of the most important issues today. Using steganography keeps information away from unauthorized people, and the information is hidden inside the original file without harming the marks. Since there is a high hiding capacity in the image, the use of image steganography is much more common than other steganography methods. In this article, the wavelet transform steganography technique is used, and the comparison results of the images before and after applying steganography, as well as the histogram output, show that this method benefits from high resistance, as well as the SNR of this method compared to other methods. The reviewed results show the superiority of this steganography method.. . . . . . . . . . . . . . . .. . . . . . . .. . . . . . . . . . . . . Manuscript profile
