Voting in the Age of Technology

William A. Edelstein, Ph.D.


     The contentious presidential election in 2000, with its infamous "hanging chads," motivated Congress to pass the 2002 Help America Vote Act (HAVA) that supplied substantial funds to upgrade America's voting technology. In practice, this opened a giant can of worms creating questions about all means of voting. The fundamental problem is that voting must be anonymous. In contrast, bank activity or financial transactions over the internet have identifiable records visible in multiple ways to bank/company staff and to users. The two most common voting systems now in use in the US are touchscreen voting machines, aka Direct Recording Electronic devices (DREs) and paper ballot optical scan (PBOS). DREs do not have permanent records of individual votes that can be independently checked, and DREs cannot be audited or recounted. DREs have caused very long lines and consequent waits (in Maryland, for example) because they are expensive and there are never enough. Multiple investigations by computer security experts have demonstrated that DREs can be hacked, and there is always the worry of malware infection. Although no examples of hacking have yet been conclusively demonstrated in actual elections, the possibility remains that this could be done in future, for example, by the government owners of the voting system, i.e. an insider attack. DREs have, in numerous cases, simply failed and irretrievably lost votes. PBOS systems are now in the majority. These are more cost effective than DREs and can be audited or recounted, as was done effectively in the 2008 Minnesota senatorial contest. The security of PBOS is much improved over the ballot stuffing days of Mayor Daley in Chicago, but there is much room for further work, particularly in carrying out random audits to confirm results. There is now a push for internet voting. This is almost universally condemned by computer security experts but their objections have been brushed aside by many election officials for whom convenience trumps all. There have been serious election technology disputes or problems around the world, such as in the UK and India. Voting technology is a fascinating and important subject which will garner a lot of activity for the foreseeable future.
