Abstract

In the present era, along with the spread of technology in different fields and the possibility of remotely accomplishing different tasks and using internal networks and the Internet, related problems and challenges have occurred. One of these problems is maintaining the security of information while sending and receiving, to prevent unauthorized access. Watermarking is the science of hiding and covering the information with the highest degree of accuracy in security, in order to securely transfer information between the points of interest, so that even when an unauthorized access happens, there is no access to the watermarked data. There are two important features in watermarking. First, the information embedding should not make significant changes in the host environment, and second, the statistical properties of the cover image and the message should be as close as possible in order to have better cryptography. The main purpose of this paper is to provide a new method based on discrete wavelet transform to achieve a suitable cryptographic method. In this method, based on wavelet transforms, color images are watermarked so that they are not normally visible and their key is needed to view them. Simulation results indicate the efficiency of the proposed method.
