| Abstract(in English) | We report that the Partial Integrity Assurance Technology (PIAT), proposed in FIT2004 by us, can be applied to compressed image files such as JPEG. In this paper, we propose the technology for the assurance of partial integrity of the image data. And even if the part of the image is changed or is sanitized, the integrity of the other parts can be assured. In addition, we implement a prototype of this technology. Images that are put on a paper scanner are signed with our prototype, and a part of the image is sanitized. Therefore, we can detect and indicate the changed part and can confirm constancy in other parts. |
