An election system provides, in one example, each voter with multiple
physical "layers" that the voter is able to choose between. The voter
takes part of the layers as a kind of receipt and the other layers are
retained and/or destroyed by the system. The actual vote is not readily
revealed by the layers taken by the voter, thus protecting against
improper influence. In the voting booth, when all the layers are
combined, however, the voter is readily able to verify the vote.
Moreover, posted images of the layers not taken by the voter can be used
to compute the election results in a way that is verifiable by interested
parties. The results cannot be changed without substantial probability of
detection and privacy of votes can be maintained unless a number of
parties are compromised or collude.
