A Comprehensive Review of Digital Data Hiding Techniques

This paper makes a study and overview of the currently existing data hiding schemes, from its primitive stages through the potential application. In the modern times with the advent of web technology information masking in digital imagery plays a main task of guaranteed protection and peer to peer data transfer between the intended users. Multitude schemes had predicted and employed on covering up secrecy from hackers. Initially availing signal concealment can be categorized into watermark, steganography cryptography, and so each has its unique benefits as well as demerits, fundamentally the insertion strategies have to follow certain features such as high capacity, robustness, security, payload and reliability. This paper gives a brief explanation of the multidisciplinary hiding strategies and their features in a comprised form using the tabular representation, such as watermarking, cryptography, and steganography.
