Quick Reminder

notebook computers during class for any

Notes on Grading Review Policy
• As sometimes there are cases where people feel
that papers have been misgraded, you are welcome
to bring them to the TA or to me so that we can
take a look.
• It’s like the NFL instant replay review system.
Unless there is obvious evidence that an error has
been made, the call made on the field stands.
• The entire exam will be regraded, including both
positive and negative corrections.
• Grades become final two weeks after they are
returned to you.
Credit Reports
• Did anyone request one?
Key Ideas
• Technology creates additional personal
content that one might wish to keep private,
creates additional ways to keep information
private, and creates additional ways for
other people to invade one’s privacy.

Data Mining
•
•
•
•
What things can they gather about you?
Who are “they”?
What good can “they” do you?
What harm can “they” do you?
People give up personal data for
relatively little return
• How many people have one of those
supermarket discount cards?
• Raise your hand if you’d give someone your
address for free. $1. $10. $20. $100.
• How much is your other information worth?
Beatriz da Costa - Swipe
• Information from driver’s license
• Data calculator
What is the value of…
• The data you have given away in the last

Kyllo vs. United States
• “In an important declaration of the constitutional
limits on new privacy-threatening technology, the
Supreme Court ruled today that the use by the
police of a thermal imaging device to detect
patterns of heat coming from a private home is a
search that requires a warrant.” -Linda
Greenhouse, NYTimes, 6/12/01
• "reasonable expectation of privacy” - 4th
amendment test
• devices that are "not in general public use"
News article yesterday 2/22/06
• Personal Data of 26.5M Veterans Stolen
• By HOPE YEN (AP)
• Personal data, including Social Security numbers
of 26.5 million U.S. veterans, was stolen from a
Veterans Affairs employee this month after he took
the information home without authorization, the
department said Monday.
A Challenge
• Pick someone famous.
• Without breaking the law, how much can we find
out about them?
• Enlist the aid of everyone with laptops.
• If you don’t have a laptop, please discuss how
you’d find out information about someone, while
your classmates with laptops work.
• 5 minutes
Front Screen
• What happened up on screen?
Etherpeg
• What is it?
• Who had heard of it?
Etherpeg
• Demoing Etherpeg in class (and next time I teach
this class)…
• Questions:
– Should I use Etherpeg without announcing it first?
– If something inappropriate appeared, who is at fault,
and who could potentially be considered to be at fault?
– What advance steps did I take (and could I take) to
protect myself without ruining the surprise?
Results
• What did we find on our famous person?
Discussion for the Day
• There has been quite a bit of discussion in the
news about warrantless surveillance activities by
the Bush administration.
• If there were a technology by which any person
could listen in undetectably to any other person’s
phone conversation, what privacy issues would
arise? Should it be legal for everyone to use?
Should it be legal for governmental use? (You
may be asked to defend either side of the last two
questions.)
• Discuss for 5 minutes.
To discuss the topic of the day,
please welcome...
