Reg,

This is a common question. It's also a good question that should be in the
FAQ. Please mention it to Karl Auerbach (karl@openvoting.org ), keeper of
the FAQ.

When the ballots are reconciled, the barcode is read and a Reconstructed
Electronic Ballot Image (REBI) is written (I saw the term REBI for the first
time in print in an Oreilly article last Monday:

http://www.oreillynet.com/pub/a/policy/2004/04/26/ovc.html

There are a number of reasons voters will have confidence that it's correct.
1) The contents of the REBI are checked against the contents of the
corresponding EBI that was copied from the voting machine.

2) The source code is all open source. While this doesn't prove it's right,
it make tricks much less likely.

3) While 1 and 2 above may not be something voters can directly verify, if
they are still skeptical they can go to a verification station to have the
barcode read while they listen through headphones as the selections are
spoken.

4) Manual checks will be done during the canvass period.

5) Other automated and/or semi-automated checks will be available such as
OCR scanning the paper and checking against the corresponding EBI.
