%X Watermark robustness to geometric attacks is still an open problem. This paper presents a new multi-bit image watermarking scheme that can resist Rotation, Scaling, Translation (RST), cropping as well as common signal processing attacks. The proposed scheme achieves watermark synchronization using Scale-Invariant Feature Transform (SIFT). The watermark is designed in a cirque pattern and it is embedded in spatial domain using odd-even quantization. An odd-even detector is designed to extract the watermark. Simulation results show that the proposed scheme achieves good image quality and it is robust to geometric attacks as well as traditional image compression, filtering operations.
