| Abstract(in English) | In recent years, vast amounts of personal information, stored electronically on servers, are accessed by various personnel within an organization. They are authorized through verification processes, but the problem of information leaks exists in such systems. With the advancement of cryptography, we can strengthen certification processes and prevent the tapping of personal information on a network. However, when persons in an organization leak information intentionally, it is impossible to prevent their actions with technology. Therefore, it is necessary to protect such information by making it possible to identify exactly the persons involved when information is leaked so that they can be punished. Until now, the methods of identifying a person leaking information usually involved analyzing access logs, but once it is clear that a particular piece of information has been leaked, in many cases it will have had a large number of accesses and determining the source of the leak from access logs alone becomes very difficult. In this paper, we propose a new log management system which will ensure that a person leaking information can be specifically identified by embedding logs into each piece of information. Digital watermark technology is important in the realization of this system and we describe in this paper a new type of digital watermark technology used for implementing our proposed system. |
