    <font face="Helvetica, Arial, sans-serif">The VVPAT on a continuous
      roll was NEVER what I and others had intended as an implementation
      of Voter Verified Paper Ballots (VVPB). The continuous roll leaves
      open the possibility of vote-selling and exposure of the ballot
      contents because the order of the voters as they enter the polling
      booth can be recorded and later synchronized to be revealed. There
      have also been problems with the paper rolls jamming and ripping,
      and there is also an electronic tally that can be used in lieu of
      the paper. This is the same with the paper sheets. Typically the
      paper is NEVER counted nor used for recounts.<br>
      <br>
      My concept of the VVPB uses the paper as the ACTUAL ballot.
      Namely, the ballot that the voter sees and VERIFIES with an
      affirmative action, is the TRUE ballot to be used for vote
      tabulation and also for purposes of recounts. For example,
      hand-prepared ballots that are publicly hand-tabulated, such as in
      the UK, would qualify as VVPBs. Hand marked paper ballots that are
      optically scanned are typically never hand-tabulated, and in some
      regions (such as Florida) their hand-tabulation is PROHIBITED by
      law. Some states, though, do provide for a hand recount of paper
      ballots that the voters prepared or verified at the time of
      voting, and that would be OK in my opinion.<br>
      <br>
      The positions of various academic proponents of different
      balloting systems has tended to change over the years. Some also
      allow for cryptographic voting, which they refer to as voter
      "verifiable" which I also find unacceptable, since the voter
      really cannot verify the mathematical implementations directly.<br>
      <br>
      For additional information about electronic voting, its inherent
      problems, and my positions and writing, see the many papers and
      articles on my website at <a class="moz-txt-link-abbreviated" href="http://www.notablesoftware.com/evote.html">www.notablesoftware.com/evote.html</a><br>

      Good luck trying to sort it all out,<br>

                      Brent, you said,<br>
                      <br>
                      Currently the " secret software  " systems coupled
                      with VVPAT's are<br>
                      condemned as insecure by government study, so we
                      don't have to consider<br>
                      the internet to sound those alarms. Ed Felton from
                      OSTP confirms.<br>
                      <br>
                      <br>
                      Can you point me to those articles? I agree
                      VVPAT's have issues. Just to<br>
                      be clear, VVPATs are ballots printed on a
                      continuous thermal paper roll.<br>
                      However, ES&S ExpressVote and the work we have
                      done for years with Prime<br>
                      III, prints a voter-verifiable paper ballot on a
                      single sheet of paper<br>
                      versus the VVPAT on a continuous roll behind a
                      glass screen. To my<br>
                      knowledge, no one has condemned this approach as
                      insecure in any way.<br>
                      Has anyone heard anything different?<br>
