Content Protection Scheme to Realize Edit Control Including Diversion Control and Composition Control

We have proposed a copyright protection technology suitable for editable contents, which can control the change, deletion, and addition of partial contents. In this paper, we propose a new scheme that can control the diversion of partial contents to other contents and composition of contents, in addition to control of the change, deletion, and addition of partial contents using digital signatures based on the author’s intention. This scheme realizes edit control between two or more contents, and is effective with Internet contents such as consumer generated media represented by YouTube. We also evaluate the security of our proposed scheme against various attacks.
