Abstract
The objective of this paper is steganography of data in images, after transform this image in any manner. Because in present to increases of social media, and internet and web networks. Therefore, it can need data security during transmit between sender and receiver. It will be proposed system for more security consisted of many phases. The first is compression image in two dimension Haar wavelet transform 2D-HWT to reduce size of image, in next is converts image to conformal mapping, and final hide secret message in image conformal mapping. The outcomes were obtained from a set of tests PSNR, MSE, Correlation Coefficient and entropy. The suggested system has excellent and efficiency, robustness, transparency, high security, and good capacity.
