Analysis of Diverse Reversible Watermarking Methods in Image Processing.

Watermarking is the current area of research in Image Processing. Since, there would be need that the data may be image, text, video and so on transferred via internet to be more secure and helps to hide something within the data. To make them secure and extract the hidden information as much as possible the watermarking is used. General watermarking only authenticates and extracts the data but not recognize the data similar to original for that purpose Reversible Watermarking is used it not only authenticates the data but also Checks the extracted data similar to the real/original data bit by bit and pixel by pixel. This paper gives the analysis of different watermarking methods used in various fields.
