Abstract
These days enormous amounts of information is at almost everyone's disposal with a single click of a button, and that too on a hand held device. Data can be present in various forms like still images, and slides of pictures like a video of GIF, over various websites present on the Internet. Because of the excessive use of this data, it also becomes important to secure it as it can be duplicated, transformed, stolen, tampered, or misused pretty easily. Recently, there has been a spike increase in the use of medical images in various E-health applications. In order to counter these potential threats, a number of watermarking techniques are being developed. A watermark is embedded in an image or document in the form of an image or pattern that can be used to authenticate the integrity of the image in question. As time goes by, the complexity of the problems that we are dealing with also keeps on increasing.
