Post-Election Audit of Memory Cards for the November 6, 2012 Connecticut Elections

Posted: June 23rd, 2014 | 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 post-election audit of the memory cards for the Accu-Vote Optical Scan (AV-OS) tabulators that were used in the November 6, 2012 elections. The cards were programmed by LHS Associates of Salem, New Hampshire, and shipped to Connecticut districts.

Cards were submitted for two reasons per instructions from the SOTS Office (a) the 10% of the districts that were randomly selected for the post-election hand-counted audit as well as any districts that were interested in participating in the audit were asked to send their cards for the post-election technological audit, and (b) any card was to be submitted if it appeared to be unusable. Given that the cards were submitted without consistent categorization of the reason, this report considers all unusable cards to fall into category (b).

The Center received 578 memory cards from 286 districts (as of March 15, 2013). This is the largest number of cards submitted since 2008. Among these cards, 375 (64.9%) fall into category (a). All of these 375 cards were correctly programmed. Out of 375 cards, 174 contain completed elections (the rest were not used in the elections). There remaining 203 cards (35.1% of all cards) were found to be unusable by the AV-OS, thus falling into category (b). Among those, 192 cards contained apparently random (or ‘junk’) data, 7 cards were unusable by AV-OS, but did not contain random data (this requires further investigation), 4 cards were formatted using AV-OS utility, however, they were not programmed. None of these cards are usable by the AV-OS for the purpose the election. Given that such cards were not selected randomly, we estimate that the percentage of unusable cards is between 6.7% and 17.7% in this audit, and this is consistent with prior audit results.

Post-Election Audit of Memory Cards for the August 14, 2012 Connecticut Primary Elections

Posted: October 16th, 2012 | 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 post-election audit of the memory cards for the Accu-Vote Optical Scan (AV-OS) tabulators that were used in the August 14, 2012 elections. The cards were programmed by LHS Associates of Salem, New Hampshire, and shipped to Connecticut districts.

Cards were submitted for two reasons per instructions from the SOTS Office (a) the 10% of the districts that are the subject of post-election hand-counted audit are randomly selected by the SOTS Office and asked to send their cards for the post-election technological audit, and (b) any card was to be submitted if it appeared to be unusable. Given that cards in category (a) belong to randomly selected districts and were used in the election, while all cards in category (b) were supposed to be submitted, and that the cards were submitted without consistent categorization of the reason, this report considers all unusable cards to fall into category (b).

The Center received 86 memory cards from 66 districts. Among these cards, 44 (51.2%) fall into category (a). All of these 44 cards were correct. Out of these cards, 16 cards show elections, with 15 cards that were actually used on Election Day (one card shows an election on a different date). There are 42 cards (48.8% of all cards) that were found to be unusable by the AV-OS, thus falling into category (b). All of these cards contained apparently random (or ‘junk’) data. These cards were unreadable by the tabulators and could not have been used in an election. Given that such cards were not selected randomly, we estimate that the percentage of unusable cards is between 1.4% and 15.9% in this audit, and this is consistent with prior audit results.

Technological Audit of Memory Cards for the April 24, 2012 Connecticut Primary Elections

Posted: August 29th, 2012 | Author: | Filed under: Post Election, Pre Election | Tags: , , , ,

The Center for Voting Technology Research (VoTeR Center) at the School of Engineering of the University of Connecticut performed pre-election and post-election audit of the memory cards for the Accu-Vote Optical Scan (AV-OS) tabulators that were used in the April 24, 2012 elections. The cards were programmed by LHS Associates of Salem, New Hampshire, and shipped to Connecticut districts.

Cards were submitted for two reasons per instructions from the SOTS Office (a) one of the four cards per district was to be selected randomly and submitted directly for the purpose of the audit, and (b) any card was to be submitted if it appeared to be unusable. Given that cards in category (a) were to be randomly selected, while all cards in category (b) were supposed to be submitted, and that the cards were submitted without consistent categorization of the reason, this report considers all unusable cards to fall into category (b).

For the pre-election audit, the Center received 124 memory cards from 110 districts. Among these 124 cards, 81 (65.3%) fall into category (a). All of these 81 cards were correct. There are 43 cards (34.7% of all cards) that were found to be unusable by the AV-OS, thus falling into category (b). In particular, 42 cards contained apparently random (or ‘junk’) data, 1 card was unusable by AV-OS, but did not contain random data (this requires further investigation). All these cards were unreadable by the tabulators and could not have been used in an election. Given that such cards were not selected randomly, we estimate that for pre-election audit the percentage of unusable cards is between 1.6% and 9.8% and this is consistent with prior audits.

Technological Audit of Memory Cards for the November 8, 2011 Connecticut Elections

Posted: April 5th, 2012 | Author: | Filed under: Post Election, Pre Election | Tags: , , , ,

The Center for Voting Technology Research (VoTeR Center) at the School of Engineering of the University of Connecticut performed pre-election and post-election audits of the memory cards for the Accu-Vote Optical Scan (AV-OS) tabulators used in the November 8, 2011 elections. The cards were programmed by LHS Associates of Salem, New Hampshire, and shipped to Connecticut districts.

For the pre-election audit, the Center received 453 memory cards from 331 districts. Cards were submitted for two reasons per instructions from the SOTS Office (a) one of the four cards per district was to be selected randomly and submitted directly for the purpose of the audit, and (b) any card was to be submitted if it appeared to be unusable. Given that cards in category (a) were to be randomly selected, while all cards in category (b) were supposed to be submitted, and that the cards were submitted without consistent categorization of the reason, this report considers all unusable cards to fall into category (b).

Among these 453 cards, 223 (49.2%) fall into category (a). 100% these cards were correct. These cards contained valid ballot data and the executable code on these cards was the expected code, with no extraneous data or code on the cards. We note that the adherence to the election procedures by the districts is improving, however the analysis indicates that the established procedures are not always followed; it would be helpful if reasons for these extra-procedural actions were documented and communicated to the SOTS Office in future elections.
