Abstract

Recently, leakage of classified information such as personal information has become serious problem. To prevent the leakage, it is important to know how the information diffuses in a computer system. In this paper, we propose a method for tracing the diffusion of the classified information. We assumed that the classified information exists in a set of files on a file system. These files will be diffused by processes (programs). Once a process touched any classified file, it becomes a suspicious carrier process. The carrier process will make other classified files. Therefore, to keep track of the diffusion, we have to watch all processes to see if they touch any classified files. That is, we have to insert some probes into an operating system to watch file manipulation system-calls of processes such as OPEN and CLOSE. We describe the algorithm of the method and an implementation of the method on the Linux kernel. We also show that the performance of our implementation is efficient.
