To resolve the common problems that the hierarchy management and control of files is weak and coarse-grained by using traditional technology in file protection,combining the multi-dimensional and multistage application environments of files,a file classified protection model based on multi-dimensional label is proposed.It combines the static characteristics label with the dynamic confidentiality label organically and introduces the concept of domain label.The security of the model is proved.Analysis and application results show that access to files in different environments can be effectively controlled without influence of normal use,thus this model can ensure the security of files.
