Auditing Use Case

Title: Auditing Diagram - Description: Auditing Diagram. This diagram highlights post-election auditing in the election process between vote tallying and election reporting.It also shows the auditing relationship between ballot casting and election verification.

The most essential purpose of post-election auditing technology is to verify election outcomes as well as how those outcomes were produced. Typically, this may be done in a completely offline manner. A full recount occurs in the case when every voter-verified ballot that was cast, counted, and reported upon is recounted for a given election. Such a process may be employed as a means for checking whether or not originally reported outcomes and recounted outcomes are the same. To perform full recounts is a lengthy, manual, and potentially error-prone process. To minimize possible causes of error, one may perform various kinds of audits, such as risk-limiting audits, which do not necessarily require a full recount, but are designed to have equivalent power to verify election outcomes when given an appropriate (representative, random) sample of an election’s voter-verified/cast ballots. Typically, a risk-limiting audit may be performed by examining single-ballots. However, multiple-ballot (batch)auditing may also be performed. Finally, this use case may also provide the opportunity for discussion of additional auditing types or approaches as well. Different auditing approaches may make use of different kinds of election process information and utilize different strategies in order to establish their conclusions.

Title: Auditing Scenarios - Description: Image showing Auditing Scenarios.
WHAT? Verify election results.
HOW? Scenarios:
1. Typical-offline, manual: Fully, manually all voter-verified and cast ballots.
2. Risk-limiting.
Case 1: Single-ballot auditing.
Case 2: Multiple-ballot (batch) auditing.
3. Other auditing types…

Image also shows the relationship between auditing and voters, election officials, and vote tallying.

Request for Feedback

For each use case scenario, please address these questions:
  1. Is the use case scenario in scope for the Next Generation VVSG for development of requirements that will undergo testing and certification? or
  2. Is the use case scenario in scope to develop as guidelines for election officials and voting system manufacturers? or
  3. Is the use case scenario not in scope for this work?
  4. If different parts of the use case scenario fall in 1., 2., and/or 3. Please identify as such.
  5. Is anything missing?
