Use Cases

1.      A registered voter logs onto the system to vote in an
election.  after authenticating the voter's identity, the system
displays a set of candidates and issues upon which the user can vote.
The user specifies his vote for some or all of the issues and then
concludes the session.  The system records these votes for later
tabulation.

2.      An unregistered voter logs onto the system to register to
vote.  The system authenticates her identity, confirms that she is
eligible to register, and requests registration information.  The user
provides the requested information and confirms her registration.  The
system records her registration and updates her status to indicate that
she is a registered voter.

3.      A registered voter logs onto the system to cast his vote in a
ballot referendum.  The system authenticates his identity and displays
information about the ballot referendum.  The user reads through
several documents related to the referendum and also views related
parts of the current state and federal laws.  The user specifies his
vote in the referendum and concludes the session.  The system records
this vote for later tabulation.

4.      A registered voter who had previously voted in an ongoing
election logs onto the system.  After authentication, the user reviews
her previous votes and changes some of her votes.  She concludes the
session.  The system records her changes for later tabulation.

5.      A citizen logs onto the system to gather information about an
upcoming election.  The user reads candidate statements, information on
ballot referenda, and aspects of the election laws.  The user then
concludes the session.

6.      A user attempts to log onto the system, but is unable to
authenticate correctly after three attempts.  The system records this
event and notifies election officials.

7.      A registered voter casts a set of votes in a single-day, closed
election that does not allow vote changes.  The voter then goes to a
different polling station and attempts to log on to vote again.  After
authentication, the system informs the voter that she cannot change her
vote or vote twice in this election.  The system records the event as
an irregularity and concludes the session.

8.      A registered voter logs onto the system to cast a vote in a
primary election.  The system authenticates the voter and shows a list
of the primaries available to him based upon his party registration.
The user selects a primary and reviews the ballot.  The user specifies
his votes, and then concludes the session.  The system records his
votes for later tabulation.

9.      A voter logs onto the system to change his personal
information.  The system determines that the requested changes do not
violate applicable laws.  The changes are then recorded into the
system.

10.     An election officer logs onto the system to initiate an
election by specifying general information about the desired election;
type, duration and voting constraints.  The system then generates a new
election and records this action.

11.     An election officer logs onto the system to add information
about ballots, ballot entries, and ballot entry choices.   The system
records this information.

12.     An election officer logs onto the system to add information
about candidates, referenda and applicable laws concerning a given
election.  The system records this information.

13.     An election officer logs onto the system to produce summary
information about an election.  The system presents the election
officer with a mechanism for selecting the desired tabulation.  The
system records this information for later access.

14.     An election officer logs onto the system to request information
about an election.  The system then presents the election office with a
mechanism for selecting the desired information.  The system then
presents the desired information.
