Information hiding and watermarking is a important issue in information security field., it has become a vigorously growing research area since the middle of the last decade. The early work on watermarking was characterized by the development of a plethora of watermarking algorithms and attacks against them. The theoretical foundations of watermarking have since then been advanced rapidly, resulting in improved watermarking algorithms as well as more accurate models of the channel capacity and error rates. However, digital watermarking research still faces many challenges. In addition, new research directions such as data forensics and authentication enable new types of application scenarios.The workshop aims to provide a high quality forum for dissemination of research results.
