A novel framework for object-based video multiple creatorship protection

Digital videos are being created jointly by many creators. It is then necessary to provide protection to the creatorship of each participating creator. This paper proposes a novel digital watermarking framework to address the problem of joint-creatorship protection for object-based video. The proposed framework makes use of digital watermarking techniques and cryptographic protocols to achieve the creatorship protection purpose. Video objects in the object-based video can be created by different creators. The framework embeds different watermarks in different video objects in such a way that each creator can show the joint-creatorship of the whole video: as well as each creator can prove his/her creatorship of video object he/she created. The complexity of the framework is analyzed by calculating the amount of data transmission and storage requirements.
