Abstract : Due to today's availability of internet technology, there is much need for data security methods. With the growing usage of communication through the internet, it has become necessary to maintain the confidentiality of the data being used and transmitted. One such technique is steganography, whereby data or information is hidden in the form of an image. Image steganography refers to the method of hiding the existence of the communicated data in such a manner that the confidentiality of the message can be maintained in a digital image. Information can be concealed using this method in the form of text, image, or video inside the cover image in an invisible form. In this paper, a review and comparison of recent advancements in image steganography are discussed. Different methods, such as spatial domain, transform domain, encryption-based, and deep learning-based methods, have been studied. Performance parameters, including PSNR, MSE, embedding capacity, and robustness, have been compared. It has been found that the use of modern methods, especially those based on encryption and deep learning, offer better security and concealment of data.
