Thank you. If that's what I gave you to understand, thank you for allowing me to correct myself.
I was pointing to one of the basic data protection principles, which says you don't use personal information except in proportion to the objective you're trying to reach. So the only way that you can correct a serious problem of electoral fraud is by using an identifier--and I certainly would not suggest the social insurance number, as it's a very strong one--then use it in proportion to the problem you think it's going to correct and only in proportion with that. But I do not know of any electoral system that uses something like the social insurance number. They usually use more public ones like the date of birth, which Mr. Kingsley suggested.
