Content Control Scheme to Realize Right Succession and Edit Control

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

“…The scheme proposed in (Koga et al, 2015) simultaneously realizes edit control and right succession and. The right succession shows the hierarchical relation between authors.…”

“…Therefore, in the proposed scheme the attacker cannot falsify the author of the partial content, if the CAC is trusted. CAC and the administration signature are not proposed in (Inamura et al, 2013) and (Koga et al, 2015). In other words, (Inamura et al, 2013) and (Koga et al, 2015) have the premise that the key for every partial content has is known for some means.…”

“…CAC and the administration signature are not proposed in (Inamura et al, 2013) and (Koga et al, 2015). In other words, (Inamura et al, 2013) and (Koga et al, 2015) have the premise that the key for every partial content has is known for some means. This paper shows the means and the structure of partial content required to verify concretely.…”

“…Previously, we proposed a copyright protection technology (Inamura et al, 2013) and (Koga et al, 2015), that divided content into partial contents, and controlled edits with respect to the change, deletion, and addition of the partial contents using digital signatures. However, the technology could not control the diversion of partial contents and the composition of contents.…”

“…However, the technology could not control the diversion of partial contents and the composition of contents. This means that the technology reported in (Inamura et al, 2013) and (Koga et al, 2015) considers only the edit control in a content. Therefore, the edit control between two or more contents became unrealizable, and the partial contents could be used contrary to the author's intention in other contents.…”
