A hybrid watermarking scheme for CCL-applied video contents

With widely spread user-generated video contents through the Internet, copyright protection issues have been arising. In this situation, creative commons license(CCL) has been introduced to make convenient sharing environment and reflect intention of content creators. However, the CCL is prone to be ignored by users because it is not protected by law or technical methods. In order for technical help, digital watermarking scheme would be applied. Conventional watermarking system, unfortunately, has many problems to support CCL-applied video contents. This paper proposes a hybrid video watermarking scheme devised for the various purposes including CCL-applied video. Experimental results show that robust watermarks are detected after scaling, cropping, clipping, and frame rate changing while fragile watermarks inform whether manipulation has been occurred on those attacks.
