Therefore, the aim of this contribution is to illustrate recent results of robust and secure watermarking to the signal processing community, and highlight both benefits and still open issues. Specifically, this paper is intended to introduce the concept of secure and robust digital watermarking system, and provide with problems and their countermeasures. First of all, the classic watermark model and cryptosystem will be reviewed and then, the concept of secure and robust digital watermarking system will be described. Next, the watermark attack will be classified and described. Finally, some countermeasures that can help to improve secure and robustness are considered.展开更多
