The main objective of digital watermarking is copyright protection of multimedia documents. A simple and fast blind watermarking algorithm applicable to any grayscale image is proposed in this paper. The watermark is embedded in the least significant bits of the original image. The algorithm is robust to watermark removal attacks due to secure selection of criteria for watermark insertion and bit position in a pixel. The method guarantees low noise insertion while embedding the watermark. The original image undergoes no visible degradations. Hence the watermarked image is also appealing to HVS.
