Digital Watermarking: Concept, Current Status, and Challenges

主讲人 : Prof.∵Yong∵Xiang

报告摘要:

Digital watermarking aims to hide watermark data (such as publisher information, user identity, file transaction/downloading records, etc.) into multimedia  s (such as audio, image, and video) without affecting their normal usage. When necessary, the watermark data can be extracted from the watermarked multimedia  s by using a secret key.  The extracted watermark data can be used for different purposes, depending on the application scenarios. For example, digital watermarking can be used for tracing multimedia piracy, secure storage and transmission of confidential data, content filtering, authentication of content and  s, and so on. In this talk, I will introduce the concept and requirements of digital watermarking, review some existing watermarking methods, and outline the challenges in digital watermarking research, which show new research directions in this area.
