copyright protection of digital media has become a major concern for owners of digital media such as images, videos, and audios. Digital watermarking is a process of hiding an image or text on an image to provide evidence of its authenticity. In this paper, we developed five different methods. We considered the transform of an image using DCT, DWT and DCT with DWT formats could affect the hidden watermark in a way or another. In addition, we considered adding additional attacks like crop image, salt and pepper noise, Gaussian noise and filter. The schemes we are providing here are resilient to these types of attacks and is novel in this scenario.
