Design and evaluation of a diffusion tracing function for classified information among multiple computers

Abstract

In recent years, the opportunity to deal with classified information in a computer has increased, so the cases of classified information leakage have also increased. We have developed a function called "diffusion tracing function for classified information" (tracing function), which has the ability to trace the diffusion of classified information in a computer and to manage which resources might contain classified information. The classified information exchanged among the processes in multiple computers should be traced. This paper proposes a method which traces the diffusion for classified information among multiple computers. Evaluation results show the effectiveness of the proposed methods. © 2013 Springer Science+Business Media Dordrecht(Outside the USA).
