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


The BIG QUESTIONS Who owns the information? What can you/they do with it? How do you manage and protect

your information?


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)


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?


One scenario…. Pizza Palace

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."


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.


Eyeglasses and NerdsA historical diversion


History of Eyeglasses China, ≈1 CE: As eye protection Italy, 1260s: For farsightedness Europe, 1500s: For nearsightedness Britain, 1725: Modern frame invented U.S.A, 1780s: Bifocals invented Britain, 1825: For astigmatisms



Historical Eyeglasses“Glasses are very disfiguring to women and girls.” From a 1901 optician journal

Glasses not for public use Used only for brief moments Led to quick use optics

Defining PrivacyI want to tell you but…


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 control2012-02-17 Katherine Deibel, Fluency in Information Technology 20

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

2012-02-17

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



Quality Principle Personal data gathered should be

Relevant to the purposes for which it is used Should be accurate, complete, and up-to-date

2012-02-17


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

2012-02-17

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


Security Principle Personal data should be protected by

reasonable security measures against Risks of disclosure Unauthorized access Misuse Modification Destruction Loss


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



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

2012-02-17

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


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


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 20052012-02-17 Katherine Deibel, Fluency in Information Technology 32

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


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


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.


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"


Digital Privacy Unfortunately, there is

Little if any government policing Lack of resources for filing complaints Few penalties for violations



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

2012-02-17

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

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?


Grocery Cards QFC Privacy Statement:

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.

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


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?
