Access Handling and Security
       By  default,  files and directories are owned by the effective user and
       group of the mounting process and everybody has full read, write,  exe‐
       cution  and directory browsing permissions.  If you want to use permis‐
       sions handling then use the uid and/or the gid  options  together  with
       the umask, or fmask and dmask options.

       Windows users have full access to the files created by ntfs-3g.

       If  ntfs-3g is set setuid-root then non-root users will be also able to
       mount block devices or via /etc/fstab if the ’user’ or ’users’ mount(8)
       option is specified. The ntfs-3g process drops the root privilege after
       successful mount and runs unprivileged afterwards.

       uid=value and gid=value
              Set the owner and the group of files and directories. The values
              are  numerical.  The defaults are the uid and gid of the current
              process.
