[steve jenkin]

The ABC Science Show had an interesting piece on secure electronic
voting today.

Dr James Heather of Surrey.
(PhD 2000. "Oh! Is it really you?--Using rank functions to verify
authentication protocols."

They've built a working "Prêt à Voter" system.
Printed forms, marked in 'pencil' and torn in half after voting.
Randomised candidate list of the left, vote on the right - which is torn
off and scanned (franked & returned to voter), while candidate list is
shredded.

The trick is a crypto-encoded number printed on the part kept.

Needs a number of co-operating 'tellers' to recover the unencrypted value.
Voters can verify on-line their vote against their printed copy.
