The idea, proposed by Ronald L. Rivest of MIT and Warren D. Smith, is
that votes are cast on paper and tallied by scanner or by hand.  After
casting their vote, each voter is given a photocopy of a randomly
selected ballot **cast by another voter**.  (A serial number, but no
name, is on each
ballot.)

At the end of the day, all votes cast are entered on a web site.  The
holder of each copy connects to the site and confirms that the ballot
whose copy they hold is present and correct, or not.  The theory is
that, even with a low proportion of web confirmations, any electoral
malpractice will be revealed with a high degree of confidence, and that
the knowledge that the scheme is in force will, in any case, deter any
attempt to rig the ballot.

Comments on the article put forward most of the obvious objections,
which are answered by the author or by Smith.  There are links to the
papers in which Rivest and Smith describe their method in detail.
