In the digital world, one of the crucial issues is protecting information transmitted over a public network; therefore, encryption and steganography methods must be used to raise the level of data security. This paper invests scrambling and encryption techniques to protect data and compress it to reduce its size, thus increasing system performance. The system is built on protecting gray images after passing a set of steps. The first step denotes the scrambling stage that scatters the locations of gray images by adopting a logistic map method to make it difficult for intruders. The second step contains scattering the image again using the same method but with a different equation and then performing encryption based on the xor operation. The third step represents embedding the data and includes dividing the RGB cover image into three bands where each band is divided into (4×4) blocks, and the bits are stored in the location (2,2) from each band. It tested the system's efficiency by conducting experiments on a set of grayscale images and then using PSNR as a measurement function, where the result was 67.9705.

“…This metric used in some watermark techniques to determine the appropriate location to embedding a watermark in an image. The points edge not suitable for embedding and can cause destroying the host image, so using this metric used to determine which block of the image is good for the embedding process, in other words, this metric preserve provides a good level of imperceptibility [22]. Edge entropy is calculated according to the equation (8) .…”

In this paper, a non-blind watermarking method for protecting the copyright of digital color images is introduced. This method based on the combination of digital transforms (DWT, DCT) in the frequency domain. The embedding process in this method depends on the partition of the host image into 16×16 non-overlapped blocks and the use of edge entropy metric to choose the appropriate blocks for the insertion process for the purpose of increasing the imperceptibility of the proposed system. As for the extraction process, it is carried out in a way that requires the presence of the original image but rather follows the same embedding protocol to extract the embedded encrypted watermark. To raise the security level, a hybrid encryption method using the chaotic map and DNA coding has been applied for encrypting the watermark before embedding it. Experimental results demonstrate that the differences between the watermarked image and the original image are indistinguishable. The proposed method is effectively resisted common image processing attacks.

Digital image authentication is an extremely significant concern for the digital revolution, as it is easy to tamper with any image. In the last few decades, it has been an urgent concern for researchers to ensure the authenticity of digital images. Based on the desired applications, several suitable watermarking techniques have been developed to mitigate this concern. However, it is tough to achieve a watermarking system that is simultaneously robust and secure. This paper gives details of standard watermarking system frameworks and lists some standard requirements that are used in designing watermarking techniques for several distinct applications. The current trends of digital image watermarking techniques are also reviewed in order to find the state-of-the-art methods and their limitations. Some conventional attacks are discussed, and future research directions are given.
