Homework discussion

• Should people always be allowed to be anonymous
  on the Internet? If so, how can illegal,
  irresponsible, or anti-social behavior be
  prevented? If not, why not and when should
  anonymity be prohibited? What level of
  identification is appropriate for various types
  of Internet interactions? Use some of the class
  readings or other articles to support your
  argument.

Homework Discussion

• Suppose some researchers were interested in
  finding out whether there was any correlation
  between grades in this class and student college,
  department, or class.
• If I were to add grade information to this table
  and give it to the researchers, would you
  consider this to be an anonymous release of this
  data? Why or why not?
• Rewrite this table so that it is k-anonymous
  where k2 and so that its value to the
  researchers is maximized
• Do you believe k2 provides a sufficient level of
  anonymity for this type of data release? Why or
  why not?

Homework discussion

• Pick a biometric identifier and do some research
  on it
• Briefly describe how this biometric is used for
  identification and/or authentication
• Describe two specific applications for which this
  biometric is currently used. (Or if it is only in
  the research prototype stage, describe two
  applications for which it is being proposed.) For
  each one be sure to say whether the biometric is
  being used for identification or authentication
  (or both)
• What advantages do proponents claim this
  biometric has over other biometrics?
• What concerns have been raised about this
  biometric?
