Content control scheme to realize right succession and edit control

We propose a copyright protection technology suitable for consumer generated media such as You Tube and CLIP. This technology realizes right succession of and edit control by the previous work's authors. In this technology, we use a digital signature to confirm the relation between the primary and secondary authors and to determine whether the contents may be edited. We propose to apply this technology to CLIP, which is a software used to operate a pre-set character three-dimensional (3D) model of a three-dimensional computer graphics (3DCG) for creating computer animation. In addition, we provide three security methods for the proposed technologies.
