Two Related IdeasPrivacy: controlling who has access to specific informationSecurity: ensuring availability and privacy of access to specific information This is all about data management
What is the data? Where is it stored? Who can access it? How can you access it?
2012-05-11 Katherine Deibel, Fluency in Information Technology 2
Security in Brief Two aspects to security
Controlling who has access Ensuring that they have access
Ensuring access is often overlooked What would you do if you lost your
cellphone and its phonebook? What if your hard drive crashes?

Backing Up It is always a good idea to make backups
of important data Rules for backing up:
Do it frequently Back up only recent changes (saves more
space than copying everything) Keep the backups physically separate from the
originals Choose mediums that you will continue to have
technology access for

The Cloud The idea of the cloud
Move computation off of local machines to the Internet
Applications provided as web services by cloud providers
Provides access wherever and whenever one can get online
2012-05-11 Katherine Deibel, Fluency in Information Technology 5
Security, Privacy, and the Cloud
Is the cloud a good place to store your personal data? Is it secure? Does it guarantee your privacy? Is it reliable?
2012-05-11 Katherine Deibel, Fluency in Information Technology 6
We will come back to these questions later
Information and PrivacyShocking stories of Victorian intrigue!

Mother is secretly half-
Welsh?!?
Information Society We live in an information society
Easy to collect, store, search, and manipulate data on record scales
Every action we do generates information Using a library Purchasing from a store Flying on a plane Doing homework Paying taxes
2012-05-11 Katherine Deibel, Fluency in Information Technology 8
The BIG QUESTIONS Who owns the information? What can you/they do with it? How do you manage and protect your
information? Who and what are you protecting it from? What needs to be protected? What needs to be managed?

The Bookstore Example You buy a book:
Cooking with Red Meat, Cheese, Lard & Beer The store has a record of the purchase How they may use it:
Ignore it Recommend books to you Target advertising Give this information to others (your health
insurance company)
2012-05-11 Katherine Deibel, Fluency in Information Technology 10
Implications What if the book was a gift?
Recommendations become poorer Advertising will reach the wrong market
Interpretation of the book's meaning Do I want to eat fatty foods? Am I studying high fat-cuisines?

2012-05-11 Katherine Deibel, Fluency in Information Technology 12
Ask yourself… Did that video bother you? Is it a realistic future?
If yes, do you want that future? If no, how much do you think could
become a reality and do you want it? Most importantly, what do we mean
when say we want some information to remain private?

What Is Privacy?S. D. Warren & L. D. Brandeis (1890). The Right to Privacy. Harvard Law Review, 4(5), pp. 193-220.
"The common law secures to each individual the right of determining, ordinarily, to what extent his thoughts, sentiments and emotions shall be communicated to others. Under our system of government he can never be compelled to express them (except upon the witness stand); and even if he has chosen to give them expression, he generally retains the power to fix the limits of the publicity that shall be given them."

What Is Privacy?
S. D. Warren & L. D. Brandeis (1890). The Right to Privacy. Harvard Law Review, 4(5), pp. 193-220.
"The narrower doctrine [of privacy] may have satisfied the demands of society at a time when the abuse to be guarded against could barely have arisen without violating a contract or a special confidence; but modern devices afford abundant opportunities for the perpetration of wrongs without the participation of the injured party."
2012-05-11 Katherine Deibel, Fluency in Information Technology 16
Implications Warren & Brandeis's argument is a
critical observation about society and new technologies: The adoption of new technologies affects
the interactions of people in society and therefore necessitates reviewing laws and rights in regards to the new technologies.

Point of Historical Sidetrack Technology usage shapes people’s
perceptions of the users Culture and society shapes how,
when, and if a technology is used
2012-05-11 Katherine Deibel, Fluency in Information Technology 24
Defining PrivacyI want to tell you but…
2012-05-11 Katherine Deibel, Fluency in Information Technology 25
A Definition What does “privacy” mean in the
modern world? The right of people to choose freely under
what circumstances and to what extent they will reveal themselves, their attitude, and their behavior to others
Privacy is a right You control when & how much is revealed Point of this lecture: You can and should
have a lot of privacy by using this control2012-05-11 Katherine Deibel, Fluency in Information Technology 26
Using Collected Information The collector can’t use after business
purpose over The collector can use it, if you
approve (OPT-IN) The collector can use it, unless you
object (OPT-OUT) The collector can use information no
matter what

Fair Information Practices
Limited Collection Quality Purpose Use Limitation
Security Openness Participation Accountability
2012-05-11
Organization for Economic Cooperation and Development (OECD) defined the “gold standard” for fair information practices
Principles
Limited Collection Principle There should be limits to the personal
data collected about anyone Collect data by fair and lawful means; Collect data with the knowledge and
consent of the person whenever appropriate and possible
2012-05-11 Katherine Deibel, Fluency in Information Technology 29
Katherine Deibel, Fluency in Information Technology 30
Quality Principle Personal data gathered should be
Relevant to the purposes for which it is used Should be accurate, complete, and up-to-date
2012-05-11
Katherine Deibel, Fluency in Information Technology 31
Purpose Principle The purposes for collecting personal data
should be stated at the time it is collected The uses should be limited to only those
purposes
2012-05-11
Use Limitation Principle Personal data should not be disclosed or
used for purposes other than stated in the Purpose Principle
Exceptions: With the consent of the individual By the authority of law
2012-05-11 Katherine Deibel, Fluency in Information Technology 32
Security Principle Personal data should be protected by
reasonable security measures against Risks of disclosure Unauthorized access Misuse Modification Destruction Loss
2012-05-11 Katherine Deibel, Fluency in Information Technology 33
Openness Principle There should be a general openness of the
policies and practices about personal data collection Should be possible to know of its existence,
kind, and purpose of use, Should be able to identity and contact
information for the data controller
2012-05-11 Katherine Deibel, Fluency in Information Technology 34
Katherine Deibel, Fluency in Information Technology 35
Participation Principle An individual should be able to
Determine whether the data controller has information about him or her,
Discover what it is in an understandable form, in a timely manner, and at a reasonable charge
Request data to erased, completed, or changed If any of the inquiries above are denied, the
individual should be able to Learn about the reasons for the denial Challenge the denial if so desired
2012-05-11
Accountability Principle The data controller should be accountable
for complying with these principles Policies, legislation, and laws to back up
the need to be held accountable
2012-05-11 Katherine Deibel, Fluency in Information Technology 36
Europe vs America EU, much of non-EU Europe, NZ, Hong
Kong, Australia, and Canada use OECD Both government and private purposes
U.S. privacy law does not use the OECD U.S. privacy law for government
information is generally strong U.S. privacy law for business is “sectoral”,
meaning it is limited to sectors and specific business practices
2012-05-11 Katherine Deibel, Fluency in Information Technology 37
U.S. Businesses and Privacy Very few industries/practices have
explicit privacy rules Almost anything goes Opting-out is the general approach
Recent federal law for medical data HIPPA: Health Insurance Portability and
Accountability Act of 1996 PSQIA: The Patient Safety and Quality
Improvement Act of 20052012-05-11 Katherine Deibel, Fluency in Information Technology 38
Think About It EU law says, “Info on EU citizens must
comply with OECD on leaving EU” U.S. privacy is so bad, EU information
cannot come here U.S.-EU are in constant negotiations
2012-05-11 Katherine Deibel, Fluency in Information Technology 39
Some Info is Protected
Family Educational Rights & Privacy Act As a general rule the University will not
release a student’s educational records to a third party without written consent of the student. This includes tuition account information.
Even includes practices of returning homework and reporting grades
2012-05-11 Katherine Deibel, Fluency in Information Technology 40
Some Info is Protected UW Libraries Privacy Policy
The University of Washington Libraries values the privacy of library users. The Libraries seeks to minimize the collection and retention of personally identifiable information.
When information is not kept, it cannot be abused.
2012-05-11 Katherine Deibel, Fluency in Information Technology 41
Digital Privacy Most reputable online business post privacy
statements on their sites Should be understandable to you Say what info they collect, Say what they will do with it How to "opt-out" or "opt-in"
2012-05-11 Katherine Deibel, Fluency in Information Technology 42
Digital Privacy Unfortunately, there is
Little if any government policing Lack of resources for filing complaints Few penalties for violations
2012-05-11 Katherine Deibel, Fluency in Information Technology 43
Katherine Deibel, Fluency in Information Technology 44
Independent Auditors Private firms organizations monitor and
report privacy violations TRU.S.Te Better Business Bureau
Social networking and public opinion can force companies to comply
2012-05-11
Real Networks in 1999 What they did:
Secretly gathered data on people’s personal music tastes
Encrypted the info so no one would know Didn’t mention it in their privacy statement
They were caught Changed privacy statement Major loss in usage Permanent marring of public trust

Cookies are Good (and Yummy)
Cookies are used by many sites and they make Web usage much better Many sites use cookies for history and logins Banking and credit card applications cannot be
secure enough without cookies If all privacy laws met OECD standards
Cookies would be all good No one but computer scientists would know about
them

Grocery Cards Easy to collect information about a
customer's eating habits Identity can be validated by credit card
Some privacy experts fear that this knowledge will be passed to health insurance companies Debatable if useful for actuarial purposes
What does the privacy statement say?
2012-05-11 Katherine Deibel, Fluency in Information Technology 52
Grocery Cards QFC Privacy Statement:
The information gathered by QFC will be used to give you, our valued customer, our very best. You have our word on that! We pledge that QFC will not release your name to any list service or manufacturer, and that such information will be held in the strictest of confidence–even within our company.
2012-05-11 Katherine Deibel, Fluency in Information Technology 53
But QFC is an affiliate of Kroger Kroger's Privacy Statement:
Kroger and its affiliates may use personal customer information to create merchandising and promotional programs tailored around specific purchases, the frequency of store visits, volume of purchases, and other data…We may share personal customer information with our subsidiaries, affiliates, agents, representatives and trusted partners for the limited purpose of providing services or information to Kroger or our customers at our direction.
2012-05-11 Katherine Deibel, Fluency in Information Technology 54
Conflicting statements? Yes But…
It is all legal in the United States We have grown accustomed to the idea
that our information is being used The U.S. is an opt-out society

Answers and the CloudAre you there, Google?It's me, Kate
2012-05-11 Katherine Deibel, Fluency in Information Technology 56
Security, Privacy, and the Cloud
Is the cloud a good place to store your personal data? The answer depends on the privacy and
security policies of the cloud service Keep this in mind:
Privacy policies may and do change Some services go away (e.g., MobileMe) Will you have network access
2012-05-11 Katherine Deibel, Fluency in Information Technology 57
Summary You may not think about privacy much,
but maybe you should … You should have a say in whether or not
records of your information can be linked to you The U.S. needs better laws, and why not?
Do you care whether Google or Facebook can deliver an ad to you based on your private information?
