How to prevent all usb mass storages from mounting?

I want to prevent every kind of usb mass storage from mounting using udev rules. Already i can detect all of usb mass storages connected to my system using following rule:

SUBSYSTEMS=="scsi", SUBSYSTEM=="block" KERNEL=="sd[b-h]1"

But i don't know how can i prevent them from mounting!

I know i have to set the authorized file of its relevant usb device to zero! but how can i find the usb device path? the $DEVPATH gives me the path of storage device block for example sdb1!

thanks in advance.

Only root can mount. If other users also have that capability then you have installed some program which do it, for example pmount, usbmount, udisks. Just search which program do it and uninstall it or configure properly. I do not think that you can do that using udev.

Please clarify, do you want to prevent USB storage devices from mounting at all or just not automatically?

My purpose is that the normal users cannot access to the content of their usb mass storages! i mean every kind f usb mass storages should be blocked before mounting! then my own written application should give the permission to usb mass storages to mount.
