Privacy What Is It

1
Privacy What Is It?

• The rights and responsibilities that govern the
  acquisition, disclosure, and use of personal
  information.
• Acquisition - from the individual, third party,
  legally or illegally, with or without the
  individuals awareness
• Disclosure - to other people or entities
• Use - storing, manipulating or evaluating
  personal information

2
Personal Information

• Any type of information that is related to a
  persons private life or concerns, recorded in
  any form.
• Can also be personally identifiable information
  (PII), which can be used to uniquely identify,
  locate or contact a person.
• Not just content - but also events (a
  transaction) that may implicate a persons
  privacy.

3
Privacy-implicating Activities An Incomplete
List

• Health Records and Medical Records
• Financial transactions of all types - tax,
  banking, etc.
• Subscriber Information -Telephones, Cable TV,
  Video Rentals, etc.
• Communications of all kinds - Telephone Calls,
  emails, etc.
• Credit History

• Purchasing History - Direct, Phone, Internet
• Student Records
• Insurance Records
• Employment Records
• Judicial History - Driving record, civil and
  criminal cases, etc.
• Internet Activities

We the Network

• If our identity is simply reduced to a magstripe,
  what is the real me or the card?
• The Net (1995) starring Sandra Bullock
• We are all living under the big net!

5
The right of the people to be secure in their
persons, houses, papers, and effects, against
unreasonable searches and seizures, shall not be
violated, and no Warrants shall issue, but upon
probable cause, supported by Oath or affirmation,
and particularly describing the place to be
searched, and the persons or things to be seized.
- Fourth Amendment to the United States
Constitution

Privacy The Two-Part Test

• ...the Fourth Amendment protects people, not
  places... Katz v. United States, 389 U.S. 347
• Courts have used a two-part test to determine
  whether, at the time of the search, a defendant
  had a legitimate expectation of privacy in the
  place or things searched
• Did the person actually expect some degree of
  privacy?
• Is the person's expectation objectively
  reasonable -- that is, one that society is
  willing to recognize?
• Katz v. United States, 389 U.S. 347 (1967)
  (Harlan, J., concurring)

7
Reasonable Expectation of Privacy

• Over the years, court rulings has set the
  precedent that the key to understanding privacy
  issues is reasonable Expectation of Privacy.
• These are the general criteria
• General legal principles no privacy if behaviors
  or communications are knowingly exposed to public
  view.
• Vantage point a point where anyone can see or
  hear what is going on
• Certain buildings or pieces of land so most
  public places come with no expectation of privacy
  (some exceptions are public phone booths and
  restrooms)
• Technological sophistication laws are constantly
  updated to adapt to new technological
  innovations.

8
Informed Consent

• A process in which an individual agrees to
  participate after being given detailed
  information about the benefits and potential
  risks of his or her action.
• The person must be advised about
• Nature (and type) of information collected
• Why and how it is going to be used
• Risks
• Freedom to withdraw

9
Opt-in vs. Opt-out

• An opt-in policy requires a potential customer to
  self-select the information (services) they wish
  to subscribe to, and how the information can be
  used.
• An opt-out policy specifies that information can
  be sent to customers without prior permission.
  But customers must be provided with the option to
  ask to be removed from the list.
• In actual designing, an opt-in approach allows
  the users to select some empty boxes of actions
  to decide which type of information they want to
  receive, while an opt-out approach leaves all the
  boxes checked by default, and the users have to
  de-select them if they do not want to receive
  that particular type of communication.
• The European Union is more inclined toward opt-in
  in its policy initiatives, while the United
  States is more toward opt-out.

10
Aspects of Privacy

• Three Key Components
• Autonomy/dignity
• Ability to exercise control
• Absence of surveillance
• Different aspects
• Information privacy collection, use and
  disclosure of identifiable personal information.
• Communications privacy private information
  should be safely delivered to the intended party.
• Privacy in public (and work) places electronic
  profiling (i.e., collecting a variety of in-depth
  information about an individual electronically)
• Home/work distinction public space/private
  space distinction

  programs are required to
• Negotiate written agreements with the other

  to Congress and OMB (Office of Management and
  Budget)

14
Online Privacy Breaches

• Online privacy can be compromised in three ways
• When personal data is saved on a local computer
• When the data is transported over the network
• When the data is stored by a third party.

15
Web Browsing Privacy

• Cookies
• Many Web pages use cookiessmall text files that
  are stored on your hard drive by the Web server,
  typically the one hosting the Web page being
  viewedto identify return visitors and their
  preferences.
• Web bugs
• A Web bug is a very small (often 1 pixel by 1
  pixel) image on a Web page that transmits data
  about a Web page visitor back to the Web pages
  server. Web bugs are used extensively by
  DoubleClick and other Internet advertising
  companies.
• Spyware
• Any software installed without the users
  knowledge that secretly gathers information about
  the user and transmits it to advertisers.

16
Other Privacy Concerns

• E-mail
• Many people mistakenly believe that the e-mail
  they send and receive is private. Since it is
  transmitted over public networks, however,
  non-encrypted e-mail can be intercepted and read
  by someone else - easily.
• Spams and Other Online Marketing Activities
• More in later lectures.
• Electronic Surveillance and Monitoring
• This can happen in public places or the work
  place. We will come back to this later.

17
More Privacy Concerns

• Invisible information gathering
• Collection of personal information without the
  subjects knowledge
• Data spillage
• Inadvertent disclosure of personal information
  because of software design glitches or accidental
  operations.
• Secondary use of personal information
• Use of personal information for purposes other
  than that was originally intended.
• Computer matching computer profiling.

18
Network Insecurity and Privacy Implications

• There are programs that can track the keyboard
  movements at a remote PC.
• Other programs can keep track of every type of
  log-on activity over the network.
• A UC Berkeley study in 2005 found that an
  algorithm can successfully decipher up to 96
  percent of the characters typed by feeding the
  audio recording of key board typing. This can be
  a form of acoustical spying over the network.

19
Cell Phones Are Ubiquitous

• More and more cell phone models have built-in
  Global Positioning System (GPS) capabilities.
• So this makes tracking in real time a cell phone
  as easy as point and click.
• ULocate is one of the commercial providers to
  offer tracking services.
• The Federal Communications Commission (FCC) has
  released its E911 (Enhanced 911) standard to
  require that emergency callers be located within
  50 meters.
• The National Emergency Number Association (NENA)
  recently approved the technical standard for VoIP
  E911 specifically targeting Internet phones.
