Performance analysis of various image steganography techniques

Information hiding is the most interesting and prominent field of data security. With the evolution of computational infrastructure, covert communication techniques have received an inclusive acknowledgment among researchers as well as common participants of data communication. Among all, an image steganography technique which is a field of data hiding is one of the foremost choices among experts. The foremost defiance in scheming a steganographic system is to preserve an adequate equilibrium among the measures. The objective of this study is to present a all-inclusive survey of disparate existing images steganography techniques (ISTs) with regard to different performance assessment standards, such as (1) camouflage image (CI) quality, (2) capacity, and (3) robustness to different attacks. Further, the underlying challenges and future directions are also highlighted.
