Information privacy is the relationship between the collection and dissemination of data,
technology, the public expectation of privacy, legal and political issues surrounding them. It is also known as data privacy or data protection.
Data privacy is a challenging since it attempts to use data while protecting an individual's privacy preferences and personally identifiable information. The fields of computer security, data security, and information security all design and use software, hardware, and human resources to address this issue.

Information types
Various types of personal information often come under privacy concerns.
Cable television
This
describes the ability to control what information one reveals about
oneself over cable television, and who can access that information. For
example, third parties can track IP TV programs someone has watched at
any given time. "The addition of any information in a broadcasting
stream is not required for an audience rating survey, additional devices
are not requested to be installed in the houses of viewers or
listeners, and without the necessity of their cooperations, audience
ratings can be automatically performed in real-time."
Educational
In the United Kingdom in 2012, the Education Secretary Michael Gove described the National Pupil Database
as a "rich dataset" whose value could be "maximised" by making it more
openly accessible, including to private companies. Kelly Fiveash of The Register
said that this could mean "a child's school life including exam
results, attendance, teacher assessments and even characteristics" could
be available, with third-party organizations being responsible for
anonymizing any publications themselves, rather than the data being
anonymized by the government before being handed over. An example of a
data request that Gove indicated had been rejected in the past, but
might be possible under an improved version of privacy regulations, was
for "analysis on sexual exploitation".
Financial
Information about a person's financial transactions, including the
amount of assets, positions held in stocks or funds, outstanding debts,
and purchases can be sensitive. If criminals gain access to information
such as a person's accounts or credit card numbers, that person could
become the victim of fraud or identity theft.
Information about a person's purchases can reveal a great deal about
that person's history, such as places he/she has visited, whom he/she
has contacted with, products he/she has used, his/her activities and
habits, or medications he/she has used. In some cases, corporations may
use this information to target individuals with marketing customized towards those individual's personal preferences, which that person may or may not approve.
Internet
The ability to control the information one reveals about oneself over
the internet, and who can access that information, has become a growing
concern. These concerns include whether email
can be stored or read by third parties without consent, or whether
third parties can continue to track the websites that someone visited.
Another concern is if websites one visited can collect, store, and
possibly share personally identifiable information about users.
The advent of various search engines and the use of data mining created a capability for data about individuals to be collected and combined from a wide variety of sources very easily.
The FTC has provided a set of guidelines that represent widely accepted
concepts concerning fair information practices in an electronic
marketplace called the Fair Information Practice Principles.
To avoid giving away too much personal information, emails should
be encrypted. Browsing of web pages as well as other online activities
should be done trace-less via "anonymizers", in case those are not
trusted, by open-source distributed anonymizers, so called mix nets, such as I2P or Tor – The Onion Router. VPNs (Virtual Private Networks)
are another "anonymizer" that can be used to give someone more
protection while online. This includes obfuscating and encrypting web
traffic so that other groups cannot see or mine it.
Email isn't the only internet content with privacy concerns. In
an age where increasing amounts of information is online, social
networking sites pose additional privacy challenges. People may be
tagged in photos or have valuable information exposed about themselves
either by choice or unexpectedly by others. Data about location can also
be accidentally published, for example, when someone posts a picture
with a store as a background. Caution should be exercised when posting
information online, social networks vary in what they allow users to
make private and what remains publicly accessible.
Without strong security settings in place and careful attention to what
remains public, a person can be profiled by searching for and
collecting disparate pieces of information, worst case leading to cases
of cyberstalking or reputation damage.
Locational
As location tracking capabilities of mobile devices are advancing (location-based services), problems related to user privacy arise. Location data is among the most sensitive data currently being collected.
A list of potentially sensitive professional and personal information
that could be inferred about an individual knowing only his mobility
trace was published recently by the Electronic Frontier Foundation.
These include the movements of a competitor sales force, attendance of a
particular church or an individual's presence in a motel, or at an
abortion clinic. A recent MIT study
by de Montjoye et al. showed that four spatio-temporal points,
approximate places and times, are enough to uniquely identify 95% of
1.5 million people in a mobility database. The study further shows that
these constraints hold even when the resolution of the dataset is low.
Therefore, even coarse or blurred datasets provide little anonymity.
Medical
People may not wish for their medical records to be revealed to
others. This may be because they have concern that it might affect their
insurance coverage or employment. Or, it may be because they would not
wish for others to know about any medical or psychological conditions or
treatments that would bring embarrassment upon themselves. Revealing
medical data could also reveal other details about one's personal life.
There are three major categories of medical privacy: informational (the
degree of control over personal information), physical (the degree of
physical inaccessibility to others), and psychological (the extent to
which the doctor respects patients’ cultural beliefs, inner thoughts,
values, feelings, and religious practices and allows them to make
personal decisions).
Physicians and psychiatrists in many cultures and countries have standards for doctor–patient relationships, which include maintaining confidentiality. In some cases, the physician–patient privilege
is legally protected. These practices are in place to protect the
dignity of patients, and to ensure that patients feel free to reveal
complete and accurate information required for them to receive the
correct treatment.
To view the United States' laws on governing privacy of private health information, see HIPAA and the HITECH Act. The Australian law is the Privacy Act 1988 Australia as well as state-based health records legislation.
Political
Political privacy has been a concern since voting systems emerged in ancient times. The secret ballot
is the simplest and most widespread measure to ensure that political
views are not known to anyone other than the voters themselves—it is
nearly universal in modern democracy, and considered to be a basic right of citizenship. In fact, even where other rights of privacy
do not exist, this type of privacy very often does. Unfortunately,
there are several forms of voting fraud or privacy violations possible
with the use of digital voting machines.
Legality
The legal protection of the right to privacy in general – and of data privacy in particular – varies greatly around the world.
Laws and regulations related to Privacy and Data Protection are
constantly changing, it is seen as important to keep abreast of any
changes in the law and to continually reassess compliance with data
privacy and security regulations. Within academia, Institutional Review Boards
function to assure that adequate measures are taken to ensure both the
privacy and confidentiality of human subjects in research.
Privacy concerns exist wherever personally identifiable information or other sensitive information is collected, stored, used, and finally destroyed or deleted – in digital form or otherwise. Improper or non-existent disclosure control can be the root cause for privacy issues. Informed consent mechanisms including dynamic consent
are important in communicating to data subjects the different uses of
their personally identifiable information. Data privacy issues may
arise in response to information from a wide range of sources, such as:
- Healthcare records
- Criminal justice investigations and proceedings
- Financial institutions and transactions
- Biological traits, such as genetic material
- Residence and geographic records
- Privacy breach
- Location-based service and geolocation
- Web surfing behavior or user preferences using persistent cookies
- Academic research
Protection of privacy in information systems
As heterogeneous information systems with differing privacy rules are interconnected and information is shared, policy appliances
will be required to reconcile, enforce, and monitor an increasing
amount of privacy policy rules (and laws). There are two categories of
technology to address privacy protection in commercial IT systems: communication and enforcement.
- Policy communication
- P3P – The Platform for Privacy Preferences. P3P is a standard for communicating privacy practices and comparing them to the preferences of individuals.
- Policy enforcement
- XACML – The Extensible Access Control Markup Language together with its Privacy Profile is a standard for expressing privacy policies in a machine-readable language which a software system can use to enforce the policy in enterprise IT systems.
- EPAL – The Enterprise Privacy Authorization Language is very similar to XACML, but is not yet a standard.
- WS-Privacy - "Web Service Privacy" will be a specification for communicating privacy policy in web services. For example, it may specify how privacy policy information can be embedded in the SOAP envelope of a web service message.
- Protecting privacy on the internet
On the internet many users give away a lot of information about
themselves: unencrypted e-mails can be read by the administrators of an e-mail server, if the connection is not encrypted (no HTTPS), and also the internet service provider and other parties sniffing the network traffic of that connection are able to know the contents.
The same applies to any kind of traffic generated on the Internet, including web browsing, instant messaging,
and others.
In order not to give away too much personal information, e-mails can be
encrypted and browsing of webpages as well as other online activities
can be done traceless via anonymizers, or by open source distributed anonymizers, so-called mix networks.
Well known open-source mix nets include I2P – The Anonymous Network and Tor.
- Improving privacy through individualization
Computer privacy can be improved through individualization.
Currently security messages are designed for the "average user", i.e.
the same message for everyone. Researchers have posited that
individualized messages and security "nudges", crafted based on users'
individual differences and personality traits, can be used for further
improvements for each person's compliance with computer security and
privacy.
United States Safe Harbor program and passenger name record issues
The United States Department of Commerce created the International Safe Harbor Privacy Principles certification program in response to the 1995 Directive on Data Protection (Directive 95/46/EC) of the European Commission. Directive 95/46/EC declares in Chapter IV Article 25 that personal data may only be transferred from the countries in the European Economic Area to countries which provide adequate
privacy protection. Historically, establishing adequacy required the
creation of national laws broadly equivalent to those implemented by
Directive 95/46/EU. Although there are exceptions to this blanket
prohibition – for example where the disclosure to a country outside the
EEA is made with the consent of the relevant individual (Article
26(1)(a)) – they are limited in practical scope. As a result, Article 25
created a legal risk to organisations which transfer personal data from
Europe to the United States.
The program regulates the exchange of passenger name record
information between the EU and the US. According to the EU directive,
personal data may only be transferred to third countries if that country
provides an adequate level of protection. Some exceptions to this rule
are provided, for instance when the controller himself can guarantee
that the recipient will comply with the data protection rules.
The European Commission
has set up the "Working party on the Protection of Individuals with
regard to the Processing of Personal Data," commonly known as the
"Article 29 Working Party". The Working Party gives advice about the
level of protection in the European Union and third countries.
The Working Party negotiated with U.S. representatives about the protection of personal data, the Safe Harbor Principles
were the result. Notwithstanding that approval, the self-assessment
approach of the Safe Harbor remains controversial with a number of
European privacy regulators and commentators.
The Safe Harbor program addresses this issue in the following
way: rather than a blanket law imposed on all organisations in the United States, a voluntary program is enforced by the Federal Trade Commission.
U.S. organisations which register with this program, having
self-assessed their compliance with a number of standards, are "deemed
adequate" for the purposes of Article 25. Personal information can be
sent to such organisations from the EEA without the sender being in
breach of Article 25 or its EU national equivalents. The Safe Harbor was
approved as providing adequate protection for personal data, for the
purposes of Article 25(6), by the European Commission on 26 July 2000.
Under the Safe Harbor, adoptee organisations need to carefully consider their compliance with the onward transfer obligations,
where personal data originating in the EU is transferred to the US Safe
Harbor, and then onward to a third country. The alternative compliance
approach of "binding corporate rules",
recommended by many EU privacy regulators, resolves this issue. In
addition, any dispute arising in relation to the transfer of HR data to
the US Safe Harbor must be heard by a panel of EU privacy regulators.
In July 2007, a new, controversial, Passenger Name Record agreement between the US and the EU was made. A short time afterwards, the Bush administration gave exemption for the Department of Homeland Security, for the Arrival and Departure Information System (ADIS) and for the Automated Target System from the 1974 Privacy Act.
In February 2008, Jonathan Faull, the head of the EU's Commission of Home Affairs, complained about the US bilateral policy concerning PNR. The US had signed in February 2008 a memorandum of understanding (MOU) with the Czech Republic in exchange of a visa waiver scheme, without concerting before with Brussels. The tensions between Washington and Brussels are mainly caused by a lesser level of data protection in the US, especially since foreigners do not benefit from the US Privacy Act of 1974. Other countries approached for bilateral MOU included the United Kingdom, Estonia, Germany and Greece.
