Abstract

A novel method for multi-bit image watermarking robust to geometric distortions is proposed. A binary watermark is embedded in a grayscale or a color host image. The ability of progressive watermark detection enables fast and robust watermark detection even after several geometric distortions of the watermarked image. The embedding of a multi-bit message and its robust decoding after the watermark detection is also discussed. Simulation results indicate the ability of the proposed method to deal with the aforementioned attacks
