PRIVACY AND COMPUTER
TECHNOLOGY
Key Aspects of Privacy:
• Freedom from intrusion (being left alone)
• Control of information about oneself
• Freedom from surveillance (being
tracked, followed, watched)
3

PRIVACY RISKS AND
PRINCIPLES
Privacy threats come in several categories:
 Intentional, institutional uses of personal
information
 Unauthorized use or release by “insiders”
 Theft of information
 Inadvertent leakage of information
 Our own actions
4

TECHNOLOGY
New Technology, New Risks:
• Government and private databases
- Thousands of databases containing personal
information about us.
- Profiles of our personal information could be created
easily.
• Sophisticated tools for surveillance and
data analysis
- Cameras, GPS, cell phones
5

• Vulnerability of data
- Leaks of data happens, existence of data presents a
risk.

New Technology, New Risks – Summary of Risks
(cont.):
 Information on the Internet seems to last forever.
 Data collected for one purpose will find other
uses.
 Government can request sensitive personal data
held by businesses or organizations.

TECHNOLOGY (CONT.)
Terminology and principles for data
collection and use:
• Invisible information gathering
- Collection of personal information about someone
without the person’s knowledge
- Unauthorized software, Cookies, ISP providers
• Secondary use
- Use of personal information for a purpose other than
the one it was provided for .

Q:
RECALL AN EXAMPLE OF
INVISIBLE INFORMATION
GATHERING ABOUT YOU…

TECHNOLOGY (CONT.)
Terminology (cont.):
Secondary use:
1- Data mining
Searching and analyzing masses of data to find
patterns and develop new information or knowledge
2- Computer matching
Combining and comparing information from different
databases (using social security number, for example,
to match records)
14

Privacy and Computer
Technology (cont.)
• Data mining - searching and analyzing
masses of data to find patterns and
develop new information or knowledge
• Computer matching - combining and
comparing information from different
databases (using social security
number, for example, to match records)
– D&D Matching
– VA Benefits
– Debate

Computer Matching
• Combining and comparing information
from more than one database. Some
examples:
–Sharing of government agencies’
databases to detect fraud by
recipients of government programs.
–Creating consumer dossiers from
various business databases.

TECHNOLOGY (CONT.)
3- Computer profiling
- Analyzing data in computer files to determine
characteristics of people most likely to engage in
certain behavior
- Businesses find new consumers
- Government detects fraud and crime activities
19

Technology (cont.)
• Profiling
– Using data in computer files to predict
likely behaviors of people. Some
examples:
• Businesses engage in profiling to
determine consumer propensity toward
a product or service.
• Government agencies use profiling to
create descriptions of possible terrorists.

TECHNOLOGY (CONT.)
Principles for Data Collection and Use:
• Informed consent
• Opt-in and opt-out policies
• Fair Information Principles (or Practices)
• Data retention
22

TECHNOLOGY (CONT.)
• Informed consent
- People should be informed about the data
collection and use policies of a business or
organization,
- They can then decide whether or not to interact
with that business or organization.
23

TECHNOLOGY (CONT.)
• Opt-in and opt-out policies
- To give people some control over secondary uses
- Under opt-out policy, the organization can use one’s
information for other purposes only if he explicitly inform
the organization (ex. Signs a form) permitting the use.
- Under opt-in policy, the collector of information may not
use it for other purposes unless the consumer explicitly
permits the use.
24

TECHNOLOGY
DISCUSSION QUESTIONS
Have you seen opt-in and opt-out choices?
Where? How were they worded?
Were any of them deceptive?
What are some common elements of privacy
policies you have read?
25

TECHNOLOGY (CONT.)
• Fair Information Principles (or Practices)
–Inform about personally identifiable information
–Collect only data needed
–Offer opt-out from email, advertising, etc
–Stronger protection of sensitive data
–Keep data only as long as needed
–Maintain accuracy of data
–Policies for responding to law enforcement
–Protect security of data.

"Big Brother is Watching You"
(cont.)
The Fourth Amendment, Expectation of Privacy
and Surveillance Technologies(p66) :
• Has technology strengthened or weakened
the Fourth Amendment???
• Weakening the Fourth Amendment
• Supreme Court decisions and expectation of
privacy
– Modern surveillance techniques are
redefining expectation of privacy

(cont.)
• The Fourth Amendment, Expectation of
Privacy and Surveillance Technologies
(cont.):
• The USA Patriot Act and national security
letters
– No court order or court oversight needed
– 2003-2005 report found "widespread and
serious misuse" of the FBIs national
security letter authorities

"BIG BROTHER IS WATCHING
YOU"
Databases:
•Government agencies collect many types
of information
•Ask business to report about consumers
•Buy personal information from sellers
•Main publicized reason: data mining and
computer matching to fight terrorism
29

YOU"
Databases:
Private information can be used to:
Arrest people
Jail people
Seize assets
30

YOU"
Databases:
• Millions of crime suspects are searched
in government databases
• Shift from presumption of innocence to
presumption of guilt
• Computer software characterizes
suspects
- Innocent people are sometimes subject to
embarrassing searches and expensive investigations
and to arrest and jail.
31

Small Sampling of
Government Databases with Personal Information
What data does the government have about you?
• Tax records
• Medical records
• Marriage and divorce records
• Property ownership
• Welfare records
• School records
• Motor vehicle records
• Voter registration records
• Books checked out of public libraries
• People with permits to carry firearms
• Applications for government grant and loan programs
• Professional and trade licenses
• Bankruptcy records
• Arrest records

YOU" (CONT.)
- Some constitution articles (laws) protect
privacy.
- Modern surveillance techniques are
redefining expectation of privacy.
- What privacy is included in those laws ?
33

YOU" (CONT.)
In some countries:
• No court order or court oversight needed to
get one’s private information.
• 2003-2005 report found "widespread and
serious misuse" of the FBIs national
security letter authorities.
34

YOU"
Two key problems arise from new technologies:
• Much of our personal information is no longer safe
in our homes; it resides in huge databases outside
our control.
• New technologies allow the government to search
our homes without entering them and search our
persons from a distance without our knowledge.
35

YOU" (CONT.)
Video Surveillance:
- Security cameras in Shopping centers, malls,
banks, etc.
- Cameras alone raise some privacy issues.
- When being combined with face recognition
systems, they raise more privacy issues.
• Increased security
• Decreased privacy

PROTECTING PRIVACY
Technology and Markets:
 Awareness:
Most people have figured out now you can’t do
anything on the web without leaving a record.
 We can decide to what extent we wish to use
privacy-protecting tools.
 We can be more careful about the information we
give out, and the privacy policies of sites we use or
visit.
57

PROTECTING PRIVACY
 Privacy-enhancing technologies for
consumers
 New applications of technology often can solve
problems that arise as side effects of technology.
 Example: cookie disablers, blocking pop-up ads,
scanning PCs for spyware, etc.
 Using usernames and passwords for Blogs visitors
(family , friends, etc.).
58

PROTECTING PRIVACY
 Encryption
 Information sent to and from websites can be
intercepted.
 Someone who steals a computer or hacks into it can
view files on it .
 Encryption is a technology that transforms data into a
form that that is meaningless to anyone who might
intercept or view it.
59

PROTECTING PRIVACY
 Encryption
 Encryption generally includes a coding scheme, or
cryptography algorithm, and specific sequences of
characters (digits or letters).
 Public-key cryptography: An encryption scheme,
where two related keys are used.
- A key to encrypt messages.
- A key to decrypt messages.
60

PROTECTING PRIVACY
 Business tools and policies for
protecting privacy
 Well- designed database.
 Using privacy audits to check for leaks of information,
review the company's privacy policy , etc.
 Some large companies like IBM and Microsoft, use their
economic influence to improve consumer privacy on the
web, by removing ads from their web sites.
