I have an encrypted loopback volume. I need to mount and umount manually the volume so I use cryptsetup luksOpen and cryptsetup luksClose .

However, When I invoke this command it pops up the /dev/mapper device under all the sessions under gnome/xfce/kde/unity ...

And then it let the user to mount (with password), expulse and unmount the volume.

It's quite annoying in a multi user server (you are working on your files and the volume is being unmounted).

How can I define ownership and permission on the device ?

I've tried chown and chmod approach witch gives nothing.
Cryptsetup doesn't have any options that let you do that.
crypttab auto mount the filesystem on boot witch is unwanted (only manual mount)
