It is and was a big theme in politics: e-Voting. Even though I was confronted with the first projects early 2000 I do not like them more 14 years later…
There are different reasons for that:
At least in Switzerland, I do not see any value. We can vote personally as well as by postal services as well as going personally in earlier days. I do not believe at all that we get a higher participation.
If there is a DDOS attack before the closure of the ballots we have a democratic problem as I could not execute my rights.
