With the development of information technology, digital works are copied illegally without the consent of copyright owners. The copied works are then spread rapidly across the world by online service providers (OSPs). Some OSPs ignore unlawful acts to create profits and commit additional criminal acts to hide their unlawful acts, such as changing or deleting log files. Consequently, there has been research on digital forensic technology to protect the intellectual copyrights of digital works and ensure integrity. In this paper, we propose a log data integrity support scheme for the reliable log analysis of OSP (LISS). The proposed scheme is used to monitor OSP events on the basis of reliable logs, thereby preventing unlawful acts such as filtering detour, and the omission, forgery, and alteration of log records; it also supports the integrity of log files essential for digital forensic investigations.
