Teachers’ Resources, Module 3:

Information about you on the Internet will be used by somebody in their interest — including against you

About This Lesson Module:

The lesson elements in this module teach students about the privacy principle “Information about you on the Internet will be used by somebody in their interest — including against you”. They are designed to be independent and flexible, so you can incorporate them into any size lesson plan.

Summary of Learning Objectives: Students can give examples of how their data may be used to benefit others; students can investigate and evaluate how different online services use data, in order to make informed choices.

Target Age: High school, college undergraduate.

Learning Objectives
  1. Students can give examples of personal data that services or sites may share with other services or companies, and examples of how those “third parties” may use that data. Examples should include both information they explicitly post and supposedly hidden information.
  2. Students can give examples of how having their personal data might benefit any of the following: friends/family, acquaintances, businesses, institutions, governments, and cybercriminals.
  3. Students can explain the business model that allows companies that provide free or cheap online services to make money by selling consumer data to advertisers and/or data brokers.
  4. Students can explain the difference between “opt in” and “opt out” models for information sharing, and relate those models to the lack of comprehensive laws regulating data sharing by companies, institutions, or governments.
  5. Student can investigate how online services use data and who they share it with, and explain how they would use this information in choosing which services to use and which data to give those services access to.
  6. Students can identify potential consequences of choosing particular privacy settings on apps, sites, and devices, in terms of how their data could be used by the parties who can see it — and whether those uses would likely be beneficial, neutral, or detrimental to themselves.

“Engage” Activities:

Use one or more of these lesson elements to introduce the topic and ignite students’ interest.

In-Class Whole-Group Activity: Dollars vs. Data

Estimated Time: 1-2 minutes.
What You’ll Need: A dollar and a piece of paper with information about you.

This activity catches students’ attention by directly comparing money and information.

  • Prepare a small slip of paper with a few pieces of information about you (e.g., name, age, school, position, favorite sports team, hobbies, etc.).
  • To open this lesson, hand one student a dollar and hand another student the slip of paper. Ask the student with the information to read it aloud. Then ask the class who got the better deal.

Target Answer: The student with the dollar got the better deal.

Details/Background for Teachers: The student with the information most likely doesn’t have a database to put it in nor a business in which that information would be relevant. But if the student with the information had other information to put it together with and customers to sell it to, it would be worth more. (See the Financial Times data calculator at http://tinyurl.com/q2joy35 for ideas on which characteristics you can list that would be worth the most.)

Optional Extension

Estimated Additional Time: 3-5 minutes.

Ask these follow-up questions:

  • Why is the dollar more valuable?
  • What circumstances would have to be different for the information to be worth more than a dollar? (In other words, how could the information be monetized effectively?)
Quick Opening Questions (Whole-Class Mini-Discussion)

Estimated Time: 10-15 minutes.
What You’ll Need: Blackboard/whiteboard (optional).

Quick Knowledge Check

How much is your personal information worth?

Follow-up Prompts:

  • Can your information be sold for money? How much?
  • Who would want to pay for it?
  • Which types of information do you think are most valuable?
  • Does your information have non-monetary value?

High-Level Answer: Information is very valuable, though the ways it can be used depend on the purposes and resources of the person or entity using it.

Details/Background for Teachers: We might not think that our information is valuable, because we don’t know how to monetize it. But online businesses compile lots of information about people, and make a profit from that combined information. In many cases, businesses will sell your information to each other, to advertisers, and to data aggregators who in turn sell it to advertisers and other businesses. In addition, data may have non-monetary value, to those who have some other interest in keeping tabs on your activities (from benign interests like friends wanting to know where you’re at to malicious interests like spying and stalking).

News Stories You Can Use
The Quick Hook

Estimated Time: 1.5 minutes per story.
What You’ll Need: Computer and projector (optional).

These news items can be used to illustrate the real-life consequences of privacy breaches. If you have a computer and projector, you can show the stories on a screen as you talk about them. If not, you can simply summarize them verbally.

  • Summary: The New York City police create a team to investigate and research rap-music videos that mention gang activity and violence; team uses lyrics as evidence in criminal investigations; artists protest that lyrics are often fictional.
Facebook Friday: Plan a Party, Good. Plan a Murder, Bad
  • Summary: A woman posts a status message on Facebook requesting that someone (anyone) assassinate the father of her child; the intended victim sees it on Facebook before the attempt and calls the police.
Optional Extension

Estimated Additional Time: 1.5 minutes per story.

For each news item, ask the students:

  • How was people’s information obtained?
  • How was the information originally meant to be used?
  • How was the information actually used?
  • Was that use beneficial, harmful, or neutral from the point of view of the person whose information it was?
  • How could the situation have been avoided?
Other Media Resources for "Engage"

Estimated Time: 5 minutes each (including questions).
What You’ll Need: Computer, projector, and speakers.

Either of these media resources can be used to open the lesson and engage students’ attention through humor.

  1. If you’re in a computer lab or students are allowed to have mobile devices in class, have them go through the calculator and answer the worksheet questions individually or in pairs.
  2. If students don’t each have their own computers/devices: Using a projector, go through the calculator as a class, calling on different students to answer each question any way they wish. Then discuss what made the biggest difference and why.
Whole-Class Brainstorm & Discussion: What Data Could They Use?

Estimated Time: 10-15 minutes.
What You’ll Need: Blackboard/whiteboard (optional).

Ask students to give examples of pieces of personal data about them that might be online. Examples can be written on the board.

Pick two or three interesting examples and ask:

  • Could this piece of information be valuable to others?
  • Who do you think could use that information?
    • Follow-Up Prompts: Institutions? Companies? The government? Your friends and family? Cybercriminals?
  • What could they use it for?
  • Would those ways of using your data help you? Hurt you? Neither?
    • Note: Students may disagree about this question, for example whether targeted advertising is beneficial; there is no right answer.

Some examples you can start them off with:

  • Example Uses for Institutions (schools, churches…):
    • Data mining/statistics, location, keeping tabs on what you do, screening candidates for admission or employment
  • Example Uses for Companies:
    • Advertising, selling it to other companies, data mining/statistics, screening candidates for employment, determining risk for credit/insurance
  • Example Uses for the Government:
    • Investigating crimes/enforcing laws, spying (foreign and domestic), security, using data to improve programs, analyzing use of services, collecting taxes
