Nice short talk on TED about a simple system for voting (Computer-Assisted VOting = CAVO? 😉 ):

David Bismark: E-voting without fraud

What I like about the idea is that:

  1. Everybody can check whether their vote was counted, and counted correctly.
  2. The data are immediately digitized, anonymized etc., so can be made immediately public. Especially for all the data geeks out there who can analyse it.
