Abstract
High quality, robust and effective watermarking techniques are presently required due to rapid utilization and growth of digital data on the internet. Watermarking can be defined as a technique that provides security to digital data, such as videos, audios and images. Digital watermarking plays a vital role in safeguarding against illegally multimedia copying. The watermark comprises secret information related to ownership, origin and copy control. The information is embedded in the multimedia content, responsible for issues related to imperceptibility and robustness.
