Title: Comp 380 Computers and Society


1
Comp 380Computers and Society
  • Political and Government Issues
  • June 8, 2007
  • Russell Gayle
  • Summer Session I - 2007

2
Net Neutrality
  • Anyone know what this means?
  • Definitions vary
  • Think of it this way
  • A broadband network free of restrictions on the
    kinds of equipment attached and the modes of
    communication allowed would be considered neutral
  • Huh? Lets Ask a Ninja!

3
Net Neutrality
  • I mainly wanted to show the Ask a Ninja clip, but
    while were on this topic
  • ISPs can
  • Block applications they do not like
  • Discriminate between content providers
  • Can some discrimination help?

4
E-Voting
  • Range of Systems
  • Optically scanned paper
  • Touch screen systems
  • Internet voting
  • All Processes (what is the weakest link?)
  • Registration
  • Ballot design
  • Voting
  • Counting of votes
  • Recounts

5
Major concerns
  • Correctness
  • Certification process
  • Digital divide
  • System set up
  • Auditing (recounts)
  • Accessibility
  • Internet vulnerability

6
Correctness
  • Should code be open source?
  • What is open source?
  • Belief that more eyes are valuable
  • Easier to hack
  • Corruption
  • Vulnerability improved by open source
  • Checking for errors that hackers can exploit
  • Malicious changes primarily a concern of which
    version is running

7
Certification
  • More than 40 states require certification
  • But what does it mean?
  • Need to guarantee certification of last minute
    fixes or changes not always possible
  • Both California and Indiana found themselves
    using uncertified code

8
Digital Divide
  • A new literacy test?
  • Intimidation
  • Difficulty executing

9
System Setup
  • Lack of local technical skills
  • Large number of local polling stations
  • Short set up time

10
Auditability vs. Privacy
  • Storing the full record means that someone could
    get at the information
  • Acceptable in England
  • Secret Ballot Act of 1872
  • Requires that each ballot be tied to the voter
  • Records held as a state secret

11
Auditing (recounts)
  • Voter Verified Audit Trail
  • Print a copy
  • Voter verifies
  • Puts it into a ballot box
  • Used for
  • Routine audits (random)
  • Recounts
  • Problems
  • Cost Australia opted out
  • Training

12
Why do an audit?
  • If you can only identify a problem, what is the
    remedy?
  • If audit can also produce the corrected results,
    more valuable

13
Broward County, Florida
  • special election to fill a state House seat
  • victor won by only 12 votes
  • 137 of the electronic ballots were blank
  • Florida law requires a manual recount
  • but no paper ballots
  • recount isn't possible

14
Other options?
  • Code can be verified against manipulating
  • Example encryption within the system
  • But, needs to get into the system
  • User interface is the vulnerable spot
  • Assuming no program errors, can we be sure that
    people will read a screen version correctly if
    they made a voting mistake?
  • Depends
  • Primarily on the quality of the ballot design

15
Partial Solutions
  • Turnout separate track of how many people voted
  • Number of votes cast should match
  • Need to count abstentions
  • Need to track people who quit in the middle
  • Does not help to determine if the vote went to
    the right person

16
Accessibility
  • Florida ban on plastic templates with holes for
    use by the visually impaired because NOT
    CERTIFIED
  • How do you address this problem without
    compromising privacy?
  • How is it done today?
  • Generally, advocates for the visually impaired
    prefer electronic voting
  • Techniques to support them, primarily audio
  • What about the paper audit trail?

17
New Mexico (last year)
  • Only two voting machines certified by the federal
    government for disabled and non-English speaking
  • Neither measures up to state law that requires
    voter-verified paper record
  • Upgrade would require 1000/machine
