Terminologies and Techniques based Image Encryption A Survey

Abstract

In this day and age of social media and smartphones, when practically all smartphone users are clicking and publishing their pictures on social media, it is of the utmost significance that the images that are transferred remain secure. Image encryption algorithms are an important part of the multimedia application landscape, playing an important part in both the security and authenticity of images. The purpose of this work is to provide an in-depth analysis of a variety of image encryption methods. In comparison to grayscale images, colored images are more affordable technologically, thus more people use them. Additionally, colored images have more information packed into them, so they are more useful. In this paper, a state-of-the-art survey of various techniques developed by various researchers in the field of image encryption is presented, and a detailed comparison of various available techniques and algorithms in the field of image encryption is carried out. Both of these aspects are addressed in the context of this particular paper.
