Tampering of Electronic Voting Machines (EVMs)
By Satinath ChoudharyProducing doctored EVMs is child’s play:
Control-units keep track of votes by recognising them only by their serial number on the list of candidates on the poll-units on which people vote. So any tampering of the control-unit chip has to be done only after the serial number of various candidates in the list of candidates appearing on poll-units have been assigned.
Normally returning officers declare the serial number assignments after the last day of withdrawal of nominations, which happens about two weeks before polling. ROM chips with mischievous codes can be readied within hours after the candidates’ serial numbers are known. During the two weeks before polling, the malicious ROM chips, or the motherboard, or possibly the whole control-unit, whatever appears easier, may be caused to replace the original ones.
Luckily, this kind of possibility of a fraud before voting can be easily remedied. Instead of declaring the serial number of candidates two weeks in advance of polling, the serial numbers may be decided at each polling booth by random draws by the presiding officers in the presence of the polling agents of various parties just an hour or so before the poll opening. Thereafter their names may be affixed on the poll-units in appropriate order in the presence of the poll-agents. All that will need to be done by the POs is, paste them on the poll-units in proper order by the time the poll opens. This entails different serial orders for candidates in different booths. But that only improves fairness towards the candidates, distributing the chance to be at the top or bottom of the list more evenly.
