You can create a group with only one user as the member, then create an ibay that belongs to that group. Only that user will be able to get in.
Note though that while admin won't get in unless you make admin a member of the group, by other means the admin/root user has access to everything on the server.
Alternatively just password protect the file eg using Word or Excel password feature.
If you loose the password though, you have lost the file for forever.
