A study and analysis of image security algorithms and the current challenges

In any era, communication is very important. In today's era effective data communication is important in all the fields. Here effectiveness was used in terms of secure communication. So, communication in the way that it is secure from any unauthorized access is important. In this paper a study and analysis were performed in the direction of image data security. This paper explores the current trends in the direction of image data security. It covers methods for image data security, tools and techniques, current challenges along with suggestive measures. It also explores the mitigating ways and directions to achieve high level image data security in the means of data communication. Cryptography and steganography methods were also being discussed, so that better methods can be selected for achieving high level data security.
