Image Steganography: Current Landscape and Critical Challenges

The practice of hiding secret information in digital images is known as steganography. In the course of time, this practice has grown immensely. Our paper looks closely at what is going on at present in image steganography. We are detailing old and new tools. We will discuss big issues related to this field, making such a practice hard to attack, tough to spot, and able to hold more data. We will also explain herein how steganography can be enhanced by machine learning. Finally, we suggest some new areas to be researched, these suggestions aims to solve the main problems and reach to a practical image steganography system.
