An image watermarking having robustness for compression and clipping

Abstract

Digital watermarking attract the attention for protection method of digital content. In this work, We propose a new image watermarking which have robustness for compression and clipping. Proposed embedding method using DCT and quantization achieves robustness for compression. The proposed method divides an input image into small blocks and then embeds watermark into all the blocks, which brings robustness for a clipping attack.
