Technological Audits of Optical Scan Voting Systems: Summary for 2007 to 2010 Connecticut Elections

Posted: October 20th, 2011 | Author: | Filed under: Audit Reports, Post Election, Pre Election | Tags: , , , , , , ,

Security and integrity concerns regarding the use of electronic voting technologies in elections necessitate comprehensive election audits. Two types of audits are routinely performed in all state-wide elections in Connecticut: random post-election hand-counted audits and technological audits. This report presents the summary of the technological audit results in Connecticut from 2007 to 2010. The technological audits were designed on the request of the Secretary of the State (SOTS) of Connecticut by VoTeR Center and are conducted by the Center before (pre-election) and after (post-election) each state-wide election and selected primaries. The technological audits focus on the information contained on the memory cards used with the AccuVote Optical Scan (AV-OS) tabulators. This report presents the cumulative results of the pre-election and post-election technological audits. The audits examine the correctness of the programming of the memory cards with respect to the specific elections and the usage patterns at the districts in light of the election procedures established by the SOTS Office. The audits also assess the reliability of the memory cards. The conclusions are that districts do not always adhere to the established pre-election procedures. Most notably, in recent elections over 6% of the memory cards are duplicated by the districts, a practice that is not permitted by the SOTS Office; additionally, the number of cards submitted for audits has been substantially lower since 2008. The audits also established that more than 10% of the memory cards may experience data loss between the time they are programmed and the day of the election; this is apparently the reason for card duplication done by the districts. This data loss is most likely caused by the weak batteries on the cards (however, as of this writing it is not clear how long a fresh battery lasts in a memory card as some cards are known to consume substantially more power than others). To provide a better statistical basis for the overall elections landscape in Connecticut, it is recommended that the number of cards examined by the audits is substantially increased.

Statistical Analysis of the Post Election Audit Data 2008 November Elections

Posted: May 13th, 2009 | Author: | Filed under: Statistical Analysis | Tags: , , , , , , ,

The Center for Voting Technology Research (VoTeR Center) at the School of Engineering of the University of Connecticut received the data gathered in the post-election audit performed in the State of Connecticut following the November 2008 election. The audits involved the randomly selected 10% of the districts and the audit returns were conveyed by the Office of the Secretary of the State (SOTS) to the VoTeR Center on December 3rd, 4th and 18th of 2008. The original audit data contained 1311 records, where each record represents information about a given candidate: date, district, machine seal number, office, candidate, machine counted total, hand counted total of the votes considered unquestionable by the auditors, hand counted total of the votes considered questionable by the auditors, and the hand counted total, that is, the sum of undisputed and questionable ballots.

Post-Election Audit of Memory Cards for the November 2008 Presidential Elections

Posted: May 13th, 2009 | Author: | Filed under: Post Election | Tags: , , , , ,

The Center for Voting Technology Research (VoTeR Center) at the School of Engineering of the University of Connecticut performed a post-election audit of the memory cards for the Accu-Vote Optical Scan tabulators that were used and to be used in the November 2008 Elections. The cards were programmed by LHS Associates of Methuen, Massachusetts, and shipped to Connecticut districts for use in the elections. The VoTeR Center received in total 462 memory cards from a number of districts after the elections. This document reports on the findings obtained during the audit. Among these cards, 279 were used in the elections, the rest remained unused, serving as back-up cards. The 279 cards represent over 30% of all districts, thus the audit is broad enough to draw meaningful conclusions. We note that in a few cases, districts apparently had problems with one tabulator and had to complete the election using another tabulator.

Pre-Election Audit of Memory Cards for the November 2008 Presidential Elections

Posted: November 10th, 2008 | Author: | Filed under: Pre Election | Tags: , , , , ,

The Center for Voting Technology Research (VoTeR Center) at the School of Engineering of the University of Connecticut performed a pre-election audit of the memory cards for the Accu-Vote Optical Scan tabulators that are to be used in the November 2008 Elections in Connecticut. The cards are programmed by LHS Associates of Methuen, Massachusetts, and shipped to Connecticut districts for use in the elections. For the pre-election audit the VoTeR Center received and examined 620 memory cards as of November 3, 2008. These cards correspond to 620 distinct districts in Connecticut. About 2/3 of these memory cards were randomly chosen by the VoTeR Center personnel during the visits to LHS and before the cards were packed and shipped to the towns. Another 1/3 of the memory cards came from the towns directly, where the cards were randomly chosen for pre-election audit (this procedure applied to the town for which the cards were not selected at LHS). The towns that shipped the cards to be audited were not asked to perform the local pre-election testing before shipping, thus the majority of the cards received from the towns did not contain the pre-election testing events in their audit logs.
