@strypey @Hamishcampbell @doryandgeoff That's precisely true but it does not make online voting a good idea. Large scale postal voting is already abused.
The other social issue is trust in the verification. This is very hard to achieve when non-technical people who are inclined to distrust the election process are asked to believe what engineers claim.
Remember #pencilgate in the UK? Or think about the claims of fraud around many recent elections.
