PROJECTS/EXERCISES
I. Discussion Questions
A. Discussion Question 1
What would you do if you looked up information about your best friend on the
Internet and found something bad?
B. Discussion Question 2
Should there be consumer data warehouses that compile masses of data about
civilians and then sell the information to companies or governments?
II. Web Projects
A. Web Project 1
Go to Google.com to find articles on ChoicePoint. ChoicePoint aggregates data
from hundreds of sources on millions of Americans. The reports are then sold to
thousands of companies and government agencies that want to know more about their
clients, customers, or employees. Find out what type of information they contain on you,
how they are protecting your privacy, and how you can correct errors that they may have
about you in the database. One place to start is the article at
http://www.msnbc.msn.com/id/7118767/ and their site at http://choicepoint.com/.
B. Web Project 2
There are many other sources of information about people on the Internet. If you
can determine what network systems other people may have IDs on, you can look up a lot
of information from the LAN domain directory using LDAP (Lightweight Directory
Application Protocol). Go to http://www.emailman.com/ldap/public.html and search for a
Smith” in a college near you. Or find out your colleges LDAP server to see whether
you can find your own entry. Note: You cannot request this resource more than 10 times
in 120 minutes.
C. Web Project 3
It has been noted that many sex offender lists contain numerous errors and are
outdated. Have each student find a sex offender in one of the local government sites and
then check the address on Yahoo. How many of the names match? Do you think sex
offenders will go out of their way to keep this data up to date? Is the data verified by
local governments? What can happen if your address shows up in the offender list?
D. Web Project 4
Access Usenet and find all the groups that someone might post to that pertain to
attending your college or this class. How many did you come up with? How many total
posts were contained in all the groups? What is the best way to filter all of these posts to
find those that would pertain to one person?
