you can count the paper votes only in your voting point/building. If there are abnormalities you can alert other people to trigger the global recounting
Yes, it's not foolproof, attacker can just modify the electronic voting data in places where he knows people don't usually do recounting. But it makes his job harder
Just want to say something in defence of cloud providers
- sometimes you need to limit the list of available CPU features to allow live migration between different hypervisors
- even if you migrate the virtual machine to the latest state of the art CPU, /proc/cpuinfo won't reflect it (linux would go crazy if you tried to switch the CPU information on the fly) (the frequency boost would be measurable though, just not via /proc/cpuinfo )
