This paper describes a new watermarking scheme for embedding a copyright watermark into a host image to protect it. In the proposed scheme, we classify the sixteen combination of binary digit of size four into four groups. We call each combination a pattern and assign a two bit value to each pattern. We embed the corresponding patterns of the watermark into the host image instead of embedding the watermark directly and obtain a better quality of the watermarked image. The experimental results show that the watermark can be extracted properly under several image processing and destroying operations.
