About the National Science and Technology Council
The National Science and Technology Council (NSTC) is the principal means by which the Executive Branchcoordinates science and technology policy across the diverse entities that make up the Federal researchand development (R&D) enterprise. One of the NSTC’s primary objectives is establishing clear national
goals for Federal science and technology investments. The NSTC prepares R&D packages aimed ataccomplishing multiple national goals. The NSTC’s work is organized under five committees: Environment,
Natural Resources, and Sustainability; Homeland and National Security; Science, Technology, Engineering,and Mathematics (STEM) Education; Science; and Technology. Each of these committees oversees
subcommittees and working groups that are focused on different aspects of science and technology. Moreinformation is available at www.whitehouse.gov/ostp/nstc.

About the Office of Science and Technology Policy
The Office of Science and Technology Policy (OSTP) was established by the National Science and Technology
Policy, Organization, and Priorities Act of 1976. OSTP’s responsibilities include advising the President inpolicy formulation and budget development on questions in which science and technology are importantelements; articulating the President’s science and technology policy and programs; and fostering strong
partnerships among Federal, state, and local governments, and the scientific communities in industry andacademia. The Director of OSTP also serves as Assistant to the President for Science and Technology andmanages the NSTC. More information is available at www.whitehouse.gov/ostp.

About the Subcommittee on Networking and Information Technology Research andDevelopment
The Subcommittee on Networking and Information Technology Research and Development (NITRD), also
known as the NITRD Program, is a body under the Committee on Technology (CoT) of the NSTC. The
NITRD Subcommittee coordinates multiagency research and development programs to help assure
continued U.S. leadership in networking and information technology, satisfy the needs of the Federal
Government for advanced networking and information technology, and accelerate development anddeployment of advanced networking and information technology. It also implements relevant provisionsof the High-Performance Computing Act of 1991 (P.L. 102-194), as amended by the Next Generation
Internet Research Act of 1998 (P.L. 105-305), and the America Creating Opportunities to Meaningfully
Promote Excellence in Technology, Education and Science (COMPETES) Act of 2007 (P.L. 110-69). For

Dear Colleagues:
Advances in networking and information technologies are among key elements for U.S.
economic growth and are essential to progress in many domains. Underpinning this progress areoften large-scale collection, processing, and archiving of information. However, the vast increasein the quantity of personal information that is being collected and retained, combined with theincreased ability to analyze it and fuse it with other information, is creating valid concerns about
privacy. Given these concerns, the Federal Government supports the need to increase research anddevelopment in privacy-enhancing technologies and related science.
We are pleased to transmit with this letter the National Science and Technology Council’s(NSTC) National Privacy Research Strategy (NPRS), developed by the Networking andInformation Technology Research and Development (NITRD) Program. It was developed in lightof the government’s recognition of the challenges to personal privacy from large-scale deployment
of information technology systems and from the challenges presented by “Big Data.” The strategy
responds to the 2014 reports, Big Data: Seizing Opportunities, Preserving Values by the WhiteHouse and Big Data and Privacy: A Technological Perspective by the President’s Council ofAdvisors on Science and Technology (PCAST).
This strategy establishes objectives and priorities for Federally-funded privacy research,
provides a framework for coordinating privacy research and development, and encourages multidisciplinary research that recognizes privacy needs of individuals and society and the
responsibilities of the government. The science and technology advances established by thisstrategy will enable individuals, commercial entities, and the government to benefit fromtechnological advancements and provide meaningful protections for personal information andindividual privacy.
We are pleased to commend this National Privacy Research Strategy as part of the
Administration’s comprehensive effort to protect fundamental values such as privacy and fairness,while advancing innovative information technologies. We look forward to working with Federal
agencies, the private sector, and the public to realize that goal.

National Privacy Research Strategy

1. Summary
People’s lives are inextricably interconnected with cyberspace and information systems. The computing
revolution is enabling advances in many sectors of the economy, while social interactions have been
profoundly affected by the rise of the Internet and mobile communications. Increasing computerizationand data collection in transportation, education, health care, and other areas will accelerate thesetrends. Massive data collection, processing, and retention in the digital era challenge long-establishedprivacy norms. On the one hand, large-scale data analytics is indispensable to progress in science,engineering, and medicine; on the other hand, when information about individuals and their activities
can be tracked and repurposed without the individual’s knowledge or understanding, opportunities
emerge for unauthorized disclosure, embarrassment and harassment, social stigma, crime,
discrimination, and misuse. The fact that such an opportunity exists can itself have a detrimental andchilling effect on people’s behaviors.
The Federal Government is mindful of this risk, and the resulting need for research and development.
The White House report Big Data: Seizing Opportunities, Preserving Values1 highlights the need forlarge-scale privacy research: “We should dramatically increase investment for research anddevelopment in privacy-enhancing technologies, encouraging cross-cutting research that involves not
only computer science and mathematics, but also social science, communications, and legal disciplines.”
The National Privacy Research Strategy establishes objectives for Federally-funded privacy research(both extramural and government-internal research), provides a structure for coordinating research anddevelopment in privacy-enhancing technologies, and encourages multi-disciplinary research thatrecognizes the responsibilities of the government and the needs of society. The overarching goal of thisstrategy is to produce knowledge and technology that will enable individuals, commercial entities, andthe government to benefit from transformative technological advancements, enhance opportunities forinnovation, and provide meaningful protections for personal information and individual privacy.
To achieve these goals, this strategy identifies the following priorities for privacy research:

2. Introduction
2.1 Privacy Research Purpose
Networking and information technology is transforming life in the 21st century, changing the way
people, businesses, and government interact. Vast improvements in computing, storage, andcommunications are creating new opportunities for enhancing our social wellbeing; improving healthand health care; eliminating barriers to education and employment; and increasing efficiencies in many
sectors such as manufacturing, transportation, and agriculture.
The promise of these new applications often stems from their ability to create, collect, transmit,
process, and archive information on a massive scale. However, the vast increase in the quantity of
personal information that is being collected and retained, combined with the increased ability to analyze
it and combine it with other information, is creating valid concerns about privacy and about the abilityof entities to manage these unprecedented volumes of data responsibly. When information about
people and their activities can be collected, analyzed, tracked, and repurposed in so many ways, it canlead to crime, discrimination, unauthorized and inadvertent disclosure, embarrassment and harassment,social stigma, inappropriate decisions, and other outcomes that may disadvantage them. That suchpossibilities exist can create a chilling effect on people’s behaviors, which can be a significant harm in
itself. A key challenge of this era is to assure that growing capabilities to create, capture, store, andprocess vast quantities of information will not damage the core values of the country.
For more than a century, citizens, lawmakers, and academics have been concerned about the effect of
new technologies on personal privacy. For almost as long, U.S. legislation has provided specific privacy
protections to consumers in an expanding set of areas. However, the progress of privacy understanding
and protection has not kept pace with the exponential increase in data collection, processing, andstorage, and the resulting risks to privacy. Today, information exists in a complex and dynamic
ecosystem that includes the collectors, who may or may not have a relationship with the individual; data
brokers, who buy, repackage, and sell collected information; analytics providers, who create systems forprocessing such information; and data users, who make decisions based upon the analytics. The
plummeting cost of storage has allowed organizations to collect large amounts of data and save the data
in long-term repositories, making such data available for unanticipated future use. Meanwhile, there is a
growing array of always-on consumer devices, environmental sensors, and tracking technologies
designed to collect, process, and archive information continuously, often without the individual knowing
exactly what is being collected about him or her and how it will be used.
It is these substantial increases in the type and amount of data collected, the scale of the analysis, andthe uncertainty of their use that is driving the current increase in privacy concerns. The availability of
disparate datasets is setting the stage for a “mosaic effect,”2 where analysis across data sets can reveal

private information or generate inaccurate inferences, even though in isolation the data sets may notraise privacy issues.
In response to this technological progress, this Administration has taken an active role in providing
leadership across a broad range of privacy issues. In the area of protecting online privacy, theAdministration released in 2011 the National Strategy for Trusted Identities in Cyberspace,3 providing aroadmap for the public and private sectors to collaborate in increasing privacy and trust in online
identities. In the area of consumer privacy, the Administration released in 2012 a careful analysis ofconsumer privacy issues and set out the “Consumer Privacy Bill of Rights,” which provides a set ofprinciples that consumers should be able to expect from products and services.4 Most recently, therelease of Big Data: A Report on Algorithmic Systems, Opportunity, and Civil Rights5 continues the
Administration’s examination of the potential privacy and discrimination risks that exist in deploying big
data and algorithmic systems.
In 2014, the U.S. Government’s investment in Networking and Information Technology Research andDevelopment was $3.9 billion.6 Within that total, the investment in privacy research activities wasapproximately $80 million.7 These research investments include explicit privacy efforts in health care,privacy regulation compliance, and multidisciplinary privacy research explorations, as well as researchon privacy as an extension of other research on computer security. Although important, this work has
not been coordinated with an overall strategy and desired goals, and as a result it has not met its fullpotential.

National Privacy Research Strategy

The President’s Council of Advisors on Science and Technology (PCAST) report8 on big data and privacy
calls for coordinating this research and using that coordination as impetus for increased Federal
investments:
With coordination and encouragement from OSTP,9 the NITRD agencies should strengthen U.S. researchin privacy‐related technologies and in the relevant areas of social science that inform the successful
application of those technologies. Some of the technology for controlling uses already exists. However,research (and funding for it) is needed in the technologies that help to protect privacy, in the social
mechanisms that influence privacy-preserving behavior, and in the legal options that are robust tochanges in technology and create appropriate balance among economic opportunity, national priorities,
and privacy protection.
In response to PCAST’s recommendation, the National Privacy Research Strategy (NPRS) establishes
strategic objectives for Federally-funded research in privacy and provides guidance to Federal agencies
for developing and sponsoring research and development (R&D) activities in this area. This researchaims to produce new knowledge and techniques that identify and mitigate emerging risks to privacy.
The purpose of this strategy is to help society realize the benefits of information technologies while
minimizing their negative societal impact. Strategies for minimizing potential risks to privacy must
consider a range of opportunities, from minimizing data collections to proper safeguarding of data oncecollected to controlling how data is used.
To achieve this objective, the NPRS calls for research along a continuum of challenges, from how people
understand privacy in different situations and how their privacy needs can be formally specified, to how
these needs can be respected and how mitigation and remediation can be accomplished should privacy
expectations and interests be violated. Finally, the NPRS highlights the need to transition research
results to governmental and commercial stakeholders so that they can improve practice as necessary
and appropriate. Appendix A summarizes the main steps in the development of the strategy.

2.2 Privacy Characterization
Privacy is surprisingly hard to characterize. A full treatment of privacy requires a consideration of ethics
and philosophy, sociology and psychology, law and government, economics, and technology. Embodying
such broad considerations, the Federal Government’s approach has been guided by the Fair Information
Practice Principles (FIPPs), a framework for understanding stakeholder considerations utilizing conceptsof fairness, due process, and information security. The Administration’s 2012 Consumer Privacy Bill of
Rights is based on the FIPPs, supplemented importantly by the concept of “respect for context.”108“Big Data and Privacy: A Technological Perspective,” PCAST, May 2014,

4National Privacy Research Strategy

Research is needed to help bridge the gap between statements of principles and effective
implementation in information systems. The Administration’s 2014 report on big data11 provides thatprivacy “addresses a range of concerns reflecting different types of intrusion into a person’s sense ofself, each requiring different protections.” Privacy can be defined in multiple ways, depending onwhether one highlights aspects such as solitude, confidentiality, the control of dissemination of personal
information, the control of one’s identity, or the negotiation of boundaries of personal spaces. Indeed,
privacy definitions and characterizations continue to evolve and are an open research question. Privacy
R&D should not be limited by any particular view or definition of privacy and should be explored frommany perspectives. Research examining the usefulness of different approaches and their applicability togeneral or specific privacy challenges should accompany such explorations.
The research of the strategy outlined in this document is based on a privacy characterization that is acombination of four key concepts: subjects, data, actions, and context, as depicted in Figure 1.

Data

Context

Subjects

Actions

Figure 1: NPRS privacy characterization.
As a coarse characterization, subjects encompasses an individual or a group of individuals, the identity(as well as pseudonymity and anonymity) of individuals and groups and their rights, autonomy, andprivacy desires. Data encompasses the data and derived information about these individuals andgroups. Actions encompasses the various data collection, processing, analysis, and retention practices,
controls that constrain such practices, as well as impacts (negative and positive) of the collection anduse of data on individuals, groups, and society. The interactions among subjects, data, and actions and

http://www.whitehouse.gov/sites/default/files/docs/big_data_privacy_report_may_1_2014.pdf.

5National Privacy Research Strategy

the interpretation of those interactions and the risk of harm are influenced and conditioned by thecontext in which they interact.
Within this characterization, “privacy” concerns the proper and responsible collection, creation, use,
processing, sharing, transfer, disclosure, storage, security, retention, and disposal of information about
people. This includes decisions by entities about when not to collect, not to create, not to transfer andnot to permit certain uses of information to protect legitimate privacy interests.

2.3 Key Challenges for Privacy
The following challenges motivate the research priorities for this strategy.
2.3.1 Influence of Context on Privacy
Individuals share personal data with people or organizations within a particular community for specificpurposes. For example, individuals may share their medical status with health care professionals,
product preferences with retailers, legal interests with law firms, spiritual concerns with religiousorganizations, and trip plans with travel agents. The community provides a context for sharing data.
When information shared with one community shows up in another outside of the intended context,
people may feel a sense of privacy violation and the purposes and values of those contexts might beundermined as well. The contextual nature of privacy makes it clear that questions about privacy
necessarily imply specifying privacy for whom and against what harm, the content, the motivation, theconditions, and for what kinds of roles and relationships.
The contextual nature of privacy creates a challenge for designing privacy-protecting systems because
people will consider privacy from varied viewpoints, may use diverse terminologies to express theirprivacy concerns, perceive privacy-related harms differently, and vary their privacy requirements withcircumstances. Moreover, system designers lack mechanisms to specify the properties that comprise
privacy and to establish that such properties are satisfied by some deployed system. Existing techniques
for specifying IT systems and the underlying computational models are not well suited for privacy. For
example, existing system specification techniques do not capture “intended purpose” or “expected use;”
however, such characterizations are crucial for the contextual view of privacy.
2.3.2 Transparency in Data Collection, Use, and Retention
Providing transparency about data collection and use practices has proven difficult. The traditional
notice and choice framework, in which data collectors/users set forth practices in lengthy privacy
policies and deem individuals to have read, understood, and consented to them, has its limits. Privacy
notices that are sufficiently detailed become too long for individuals to read and give meaningfulconsent, while notices that are phrased broadly in order to cover all anticipated future uses lacksufficient details for consent to be meaningful. Today, there are so many organizations seeking to collectand use information that individuals realistically do not have the ability to evaluate each collection
notice and associated data use. Looking forward, as surroundings are increasingly instrumented withsensors that continuously collect data in domains such as transportation, environmental control, or
public safety, protecting privacy through existing disclosure mechanisms may be even more challenging.
6

National Privacy Research Strategy

Better solutions are needed to support the various purposes of transparency, for consent and choice forindividuals and for oversight by regulators.
There is also very little public understanding of data retention practices and their potential implications.
For instance, the availability and persistence of collected data can belie people’s expectations thatminute details of their past will not be forever available. It can also contradict individuals’ expectations
about how collected data will be used, because providing notice of prospective changes in data-handlingpractices can be challenging. Data longevity also makes it difficult for individuals to withdraw or change
their consent regarding particular data uses.
2.3.3 Data Aggregation, Analysis, and Release
Increased capabilities in data collection, aggregation, analysis, and machine learning are fueling thediscovery of new patterns, correlations, and knowledge about the world, and an increasing use ofclassifying and predictive algorithms. Individuals are often unaware of the outcomes of these algorithms
and technologies that score and evaluate them for a variety of purposes. Organizations are increasingly
relying on non-public algorithms to make a variety of decisions or direct action. However, there is a riskthat predictive algorithms could, for example, enable decisions that result in (perhaps unintended)
consequences such as bias and discrimination. Unintended consequences can and do occur, and theactual scale and ramifications of them are not known.
The growing interest in publishing statistics, analyses, and raw data held by the Federal Government
raises privacy concerns as well. Existing approaches for protecting privacy, such as the removal of
personally identifiable information (PII), have not been able to address the privacy risks of large-scaledata collection, analytics, and release. As more information about individuals is retained and madeavailable, data analytics can often be used to link sensitive information back to individuals, despite
efforts to anonymize data. This situation creates opportunities for personal information to be misused.
Other approaches to privacy protection, such as k-anonymity12 and differential privacy,13 can better
address some privacy risks while allowing for some beneficial data uses; however, they unavoidably
come at a cost in the utility of data.

2.4 Desired Outcome
The goal of this NPRS is to produce knowledge and technology that will enable individuals, commercial
entities, and the government to benefit from technological advancements and data use while
proactively identifying and mitigating privacy risks. Solutions are needed that will allow people to12

k-anonymity is a formal model for privacy protection. A dataset provides k-anonymity protection if theinformation for each person contained in the dataset cannot be distinguished from at least k-1 individuals whose
information also appears in the dataset. By L. Sweeney, "k-anonymity: a model for protecting privacy,"International Journal on Uncertainty, Fuzziness and Knowledge-based Systems, October 2002, pgs. 557-570.
13
Differential privacy is a formal model for privacy in statistical databases. The model allows one to learn
properties of the population as a whole, while protecting the privacy of the individuals in the sample. This isachieved by adding a certain amount of synthetic, "noisy" data to the database such that the contribution of any
individual to the overall, statistical properties of the information in the database can't be distinguished. By C.
Dwork, Microsoft Research, http://research.microsoft.com/pubs/64346/dwork.pdf.

National Privacy Research Strategy

negotiate and establish boundaries of personal spaces with the world around them, with confidence inthe process and in the outcomes of the negotiations.
Privacy creates opportunities for political expression and choice. Privacy protections also provide aspace for negotiation between consumers and businesses about data practices. When privacy is notprotected, individuals and society suffer from harms, such as erosion of freedom, discrimination, loss oftrust in institutions, or reduced innovation from self-censoring by the population.
Sustaining privacy requires technologies targeted for particular use, as well as foundational science andengineering to develop capabilities to analyze contexts that might lead to privacy harms and produce
technologies to prevent or mitigate them. Whereas much work to date on privacy has focused on
specific narrow technologies and applications, this strategy seeks the development of scientificfoundations for privacy that would enable rigorous analysis of the drawbacks, risks, harms, and potential
benefits to privacy and society from data collection, processing, and analysis systems; and developmentof technologies that better protect privacy and allow more robust and precise negotiation of privacy
expectations.
This strategy does not attempt to set privacy standards or norms; however, the research outcomes ofthis strategy should support individuals and the Federal Government in achieving privacy protections
and in sustaining societal values as discussed in policy documents including Cyberspace Policy Review,14
U.S. International Strategy for Cyberspace,15 Consumer Data Privacy in a Networked World,16 and Big
Data: Seizing Opportunities, Preserving Values.17 Likewise, this strategy does not address privacy policy
issues associated with law enforcement or national security (although the research under this strategy
should help clarify many related issues). Appendix B further discusses the legal and policy context for
privacy in the United States.
Moreover, this strategy does not address how to rectify poor computer security or information
protection practices—which can cause privacy harms. Federal research strategy for improving computerand cyber security is presented in the 2016 Federal cybersecurity R&D strategic plan.18

National Privacy Research Strategy

Finally, this strategy does not define specific research agendas for individual Federal agencies; rather, it
sets objectives for the Executive Branch, within which agencies may pursue priorities consistent with
their missions, capabilities, and budgets, so that the overall research portfolio is consistent with thisstrategy. The priorities will be coordinated within the NITRD Program by facilitating mutual awareness ofeach agency’s strategies and goals, while providing agencies with flexibility to determine responsive
research agendas and activities.

3. National Privacy Research Priorities
The following research priorities, jointly established by the information technology research-funding
agencies, focus on critical capability gaps in the privacy domain. The priorities provide a strategy;
Federal agencies will be responsible for making tactical decisions about how to structure, fund, andexecute specific research programs based on their missions and capabilities, so that the overall research
portfolio is consistent with this strategy. This strategy is intended to inspire a range of parallel efforts inthe private sector.

3.1 Foster multidisciplinary approach to privacy research and solutions
This strategy aims to advance research that will improve government agencies’ ability to protect privacy
while executing their missions and responsibilities, and more generally, improve civil society’s ability tocreate systems that collect and process information in a manner that respects privacy, ensures fairness,and prevents unfair discrimination. To achieve these objectives, this strategy calls for multidisciplinary
research involving disciplines such as computer science, social and behavioral sciences, biomedical
science, psychology, economics, law and policy research, and ethics. Multidisciplinary approaches arenecessary in order to be able to characterize privacy goals and harms, understand privacy events (actsand actions with the potential to compromise privacy; privacy events may or may not be considered
privacy violations and may or may not result in privacy harms), engineer privacy-protecting systems, andrecover from privacy violations.
Furthermore, there can be profound challenges to deploying and otherwise maximizing the results ofprivacy research. Deploying new privacy-aware approaches may require changes in existing technology
systems, in business processes, in regulations, and in laws. These costs must be explicitly recognized andaddressed; otherwise, many long-term benefits of increased privacy protection will not be realized.
Multidisciplinary approaches are needed to understand how the adoption of privacy protections isadvanced or impeded by policy and regulatory factors, organizational and business aspects, market
competition, and economic and social incentives or disincentives. Multidisciplinary research is needed tohttps://www.whitehouse.gov/sites/whitehouse.gov/files/documents/2016_Federal_Cybersecurity_Research_and_Development_Stratgeic_Plan.pdf.

9National Privacy Research Strategy

gain insight into whether and when privacy protections are addressed best technologically or throughethics and policy, or some combination of all methods.
Efforts to maximize adoption of privacy protections must also consider potential market inefficiencies,
such as asymmetric information between consumers and producers, where there is an aspect of productquality which consumers have much less ability to evaluate compared to producers. This may lead tounderinvestment in producing that aspect of quality—in this case, in producing privacy-protective
features. Learning from fields with similar potential market inefficiencies (e.g. product safety,
environmental pollution) may provide some research models for types and combination of solutions toaddress and support adoption of privacy protections.

3.2 Understand and measure privacy desires and impacts
Privacy desires are often diverse, context specific, dynamic, difficult to predict, and difficult to measure.
Research is needed to develop methods and technologies that provide the capabilities to characterize
the various and evolving desires, expectations, norms and rules for activities, information disclosure,and data flows in the digital realm that involve private information. Effective techniques to understandprivacy desires in context and over time will strengthen the development of techniques that assist
individuals in making and controlling their privacy choices, in anticipating potential privacy issues withintroduction of new technologies, and in capturing privacy requirements for the purposes of building
privacy-protecting systems. Research is also needed to understand the overall benefits of privacy forsociety and the ways privacy interacts with other societal goals.
System designers and developers need to better understand what people value regarding privacy, what
are people’s privacy desires and expectations, and in what ways privacy might be infringed upon, inorder to develop systems that are more respectful of peoples’ privacy choices. A better understandingof individuals’ privacy interests is also important to understanding what types of information must be
given to individuals to enable them to make informed choices about their activities. Furthermore,
greater awareness of privacy desires and perceived deviations from those desires can inform social andlegal policy.
However, achieving such understanding is difficult. Privacy desires can vary by generation, cultural
subgroup, national interest, socioeconomic status, and other factors. These variations can make it
difficult to draw general conclusions about current privacy norms or predict how these norms may
develop over time. Similarly, privacy impacts are shaped by and evolve with the use of new technologies
and in new contexts.
Current methods for determining public opinion and gauging privacy desires have significant limitations.
Self-reporting assessments, such as surveys, can pose a “privacy paradox” where people profess thatthey are concerned about privacy, but their on-line actions seem not to be driven by those concerns.
Newer techniques for surveying public opinion—for example, by analyzing social media—are promising,but these techniques can be systematically biased, miss important population segments, or bemanipulated. Alternatively, behavioral assessments and measurements (analyzing peoples’ actual
10National Privacy Research Strategy

behavior and choices as opposed to their self-assessments) are also problematic, as it is difficult to teaseout peoples’ privacy desires from actions that they perform within the constraints of a particular IT
environment. The IT environment within which the behavior takes place guides individuals’ behavior andthe behavior itself may not be a good indicator of the actual privacy desires.
In addition to measuring privacy desires, it is important to be able to measure privacy impacts andcompare them with privacy desires. Some privacy impacts may occur as the result of a specific event (forexample, a data breach) or the introduction of a new process or technology that helps to protect privacy
or increases privacy risk. Other impacts may occur as the result of an accumulation of disparate dataover time that, when combined, reveal private information or result in inferences not possible inisolation. It is necessary to systematically identify and assess privacy impacts and desires, and consider
how they interact with other goals of individuals, organizations, and society as a whole such as
convenience, cost savings, and utility for public health and safety.
Various privacy events occur when there are deviations from privacy rules, norms, desires, or
expectations of a group or individuals. Research is needed to develop methods and technologies forbetter understanding, detecting, and assessing such deviations and privacy harms that may occur as aconsequence. In particular, solutions are needed to detect privacy events when these events are notdirectly identifiable by individuals. This can occur, for example, when an algorithm uses inappropriate
information for making a decision. Research addressing privacy events should also aim to clarify thewide range of effects of technology on individuals and society, including the chilling effects of datacollections.
For these reasons, this strategy calls for research on techniques for understanding and measuring
privacy desires and impacts. Such research should include techniques for assessing the emergence,codification, and revision of societal practices, attitudes, and beliefs regarding privacy and harms fromprivacy events. Addressing these issues must involve technological, behavioral, economic, cultural,social, educational, psychological, ethical, and historical perspectives and related analyses.
Explicit in the improved understanding of privacy desires and impacts must also be the ability to define
various privacy objectives (e.g., individual control, accountability, respect for context, and transparency)
and the ability to measure how information systems meet or don’t meet those objectives. The
measurements should aid individuals in helping them make informed privacy-related decisions as well as
support machine-based analysis and reasoning.
Key research questions include:What research methods most reliably and validly sample, measure, and represent people’s
privacy desires, expectations, attitudes, beliefs, and interests in one or more communities?
To what extent do privacy desires, expectations, attitudes, beliefs, and interests vary bygeneration, by cultural subgroup, by national interest, by socioeconomic status, or by otherdemarcations?

How can the relationship of privacy objectives and other objectives of individuals, organizations,and society be understood and assessed?
How can the effects of privacy policy approaches on privacy incidents and markets, both
domestically and internationally, be evaluated?

3.3 Develop system design methods to incorporate privacy desires,
requirements, and controls
Systems engineering is an interdisciplinary approach to organizing the total technical and managerial
effort required to transform a set of stakeholder needs, expectations, and constraints into a solution
and to support that solution throughout its life. When systems process personal information, whether
by collecting, analyzing, generating, disclosing, retaining, or otherwise using the information, they can
impact privacy of individuals. System designers need to account for individuals as stakeholders in theoverall development of the solution. However, designing for privacy does not today have parity withother disciplines when it comes to engineering solutions that capture the appropriate protections and12National Privacy Research Strategy

stakeholder interests for privacy. Designing for privacy must connect individuals’ privacy desires withsystem requirements and controls in a way that effectively bridges the aspirations with development.
System designers often lack appropriate tools for designing systems that incorporate effective privacy
requirements and controls. Even when designers do consider privacy at the beginning of the design
process, they lack a systematic approach for understanding and assessing the risks that a system mightpose to privacy, for identifying and expressing privacy requirements for a system, and for designing
controls that can achieve those goals. In contrast to other fields, privacy lacks models that provide
quantifiable methods for describing risk.
Risk identification and management is only one part of overall systems engineering. System engineers
also need consistent privacy objectives oriented around engineering processes to allow them to develop
system-level requirements and capabilities to implement privacy policies. System owners are often
faced with conflicts among various organizational objectives such as efficiency, cost, functionality,
mission, and system quality attributes (e.g., security, safety, privacy, etc.) that force them to maketradeoffs. Without privacy engineering objectives, it is more difficult for system owners and engineers toanalyze how privacy interacts with other system objectives. Research is needed to find approaches thatwill minimize such tradeoffs and allow engineers to identify solutions that maximize both privacy andother objectives to the greatest extent possible.
Furthermore, research should be aimed at developing tools to help system designers choose, test, andvalidate among different privacy controls, as well as developing approaches for combining multiple
privacy-preserving mechanisms in operational systems. For example, as a tool for bridging the gap
between privacy principles and system implementation, design patterns could enable system designers
to better apply and share solutions to common privacy problems.
With better frameworks and tools for privacy engineering and risk management, research can advancearound technical controls and how system designers can most effectively apply them in systems. Some
privacy controls can be categorized as organizational controls, but there are many cryptography-based
technologies that could be deployed at the system level to achieve privacy-positive outcomes. Making
combined progress on frameworks, risk models, and technical controls will improve the capability toassess privacy risk in specific systems and compare the effectiveness of different privacy controls.
Ultimately these techniques should make it possible to transform measurements into end-to-end
determinations as to how processing of personal information affects privacy.
Research is needed to develop methodologies to connect evolving privacy desires to system design andto development. In security, the threats may change but security objectives and design and engineering
methods are quite stable and use risk-based processes to account for changing threat environments.
Likewise, it is important to define consistent privacy-related objectives and processes that allow for theinterchange between privacy desires and the evolving technology environment.
Key research questions include:

needs?
What metrics and measurements can measure both privacy and system utility, to understandthe tradeoffs between the two, and to support the development of systems that can maximize
both?

3.4 Increase transparency of data collection, sharing, use, and retention
Individuals face considerable burdens in understanding today’s complex and dynamic information
ecosystem. While some information is collected from individuals in a relatively transparent fashion, agreat deal of information may be collected without an individual’s knowledge and by data collectors
with whom the individual has no relationship. The growing use of sensors in both the home and in public
space for public safety, transportation, and environmental purposes has also resulted in the collection ofvast amounts of data on individuals. Because much of this data collection and use is invisible toindividuals, they often are unaware of when data about them is collected or for what purposes it will be
used. In addition, individuals often do not understand the extent to which data about them is sharedwith third parties. This lack of awareness leads to the individual being unable to make informed
decisions about the tradeoffs involved in sharing personal information in exchange for some personal orsocial benefit.
Research designed to increase transparency of data collection and use would enable individuals tobetter evaluate the privacy implications and potential benefits of their activities and would permit datacollectors/users to develop data practices that respect and protect individuals’ privacy desires.
Increased transparency of data collection and use will also enable privacy technologists to develop
solutions that better address the needs of individuals and data collectors/users, and it will provide
regulators with improved visibility into data collection and use activities.
The notice-and-choice approach has attempted to promote transparency for otherwise invisible
practices. Today, many data collectors disclose their data practices through privacy policies. Public
posting of privacy policies promotes data collectors’ accountability for their practices; however, privacy
policies are often difficult to locate, overloaded with jargon, and ambiguous or open-ended in their
14

National Privacy Research Strategy

meaning, rendering them confusing and even incomprehensible. The burden on individuals to read andunderstand these policies is further compounded in the mobile context where, because of the small sizeof the device, a privacy policy may be spread out over 100 separate screens. Some data collectors/users
have begun to experiment with innovative approaches such as “just-in-time” disclosure that provides
small, understandable amounts of information at relevant points in a transaction. The Administration
facilitated a multistakeholder effort to standardize the presentation of privacy policies for mobile apps
to enhance their legibility, accessibility, and ubiquity.19 However, more research is needed to determine
how traditional and newer transparency mechanisms can be improved and to identify other promising
methods of disclosure.
Data have also become very durable. Because electronic storage is inexpensive and takes up very little
space, data collectors are not only collecting greater amounts of information than they have in the past,
they are also storing that information for longer periods. Accordingly, developing effective means for
informing individuals about prospective uses of their information is critical in achieving information
symmetry between people and data collectors/users.
In addition, there has been insufficient effort to develop means to increase consumer awareness andunderstanding of today’s systems, business practices, and information flows. Greater understanding
regarding specific business models, the tools available to individuals to control the collection and use of
their data, and the benefits and privacy implications of various data uses would alleviate much of theexisting information disparity between people and data collectors/users.

preferences of individuals?
How can the format and lexicon for describing data practices across industries be standardized,
taking into account the inevitability of changes in technology over time? What other measures
could improve individuals’ ability to compare data practices across the range of datacollectors/users, thereby encouraging competition on privacy issues?
What might be the appropriate level of transparency and choice for prospective changes todata-handling practices? How can the impact of these changes be measured?
How can individuals be provided with notice about the practices of data collectors that collectand use data without directly interacting with individuals?

3.5 Assure that information flows and use are consistent with privacy rules
Individuals not only need to understand the rules that govern flows and use of personal data, they needto have confidence that those rules are observed in practice. Research is needed to advancetechnologies that can assure that personal data are linked with the rules appropriate for the context inwhich they are collected and that operations applied to those data are governed by those rules.20
Research is also needed to determine whether privacy rules for the output data could be derived fromrules associated with the inputs, the processing, and the permissible use (context) for the outputs.
Attaining such capabilities could require new computational models and languages for making precise
and implementing as code the essential premises about intent and desires for information use that are
implicit when privacy is viewed as contextual.
For example, techniques are needed that allow data to be reliably tagged and processed in a way that
preserves the context under which they were collected and are maintained. “Context” is a broadconcept that might include a person’s consent and preferences, regulatory requirements, geographicallocation, or data sharing agreements. Such tags could capture the acceptable data uses signaled by theindividuals and allow data collectors to ensure that subsequent users will continue to honor both theperson’s permissions and the specific requirements for individual data. More broadly, these techniquesshould facilitate people’s expression of privacy preferences and their implementation.
Ways to associate rules with code are also needed, so that other code can verify that rules are being
faithfully executed and so that the resulting data can be associated with the rules under which they
were collected and processed. Together, these approaches can help create accountable systems where
violations of privacy policy can be detected and made known to affected persons.
Improved technology for managing data use would make it possible for data-processing and storage
organizations to determine, rapidly and reliably, if their handling of private information meets legal,
regulatory, and ethical standards. Such technology would have the additional benefits of allowing
erroneous data to be found and either corrected or deleted.

These approaches will help ensure that the responsibility for using personal data in accordance with theperson’s preferences will rest with data collectors, processors, aggregators and service providers. They

and management of multiple identities be made efficient and practical?
Can existing Internet infrastructure and protocols be redesigned to better support privacy (i.e.,
support anonymous, censorship-resistant, and metadata-hiding communications)? Can privacy
be built into core Internet services without adversely affecting cybersecurity?

3.6 Develop approaches for remediation and recovery
Recovering from perceived or actual privacy violations requires remedies. Frequently, there is no legal
recourse or even legal recognition that a privacy violation has taken place. Existing recovery mechanisms
are limited and are inconsistent in their efficacy. The difficulty of recovery magnifies the importance ofprivacy risks and increases the impact of the information asymmetry between individuals and datacollectors/users. By understanding how data actions operate (collections, flows, uses, disclosures ofcertain information, etc.) and how they may result in harm, better approaches for recovery might bedevised.

17

National Privacy Research Strategy

Research is needed to measure the efficacy of existing technical, economic, and legal redress
mechanisms (e.g., credit freezes and monitoring, privacy-protection insurance, liability regimes forprivacy compromises), and to evaluate the consequences of a lack of redress. New approaches forrecovering from privacy events need to be developed that are fast, predictable, and easy to implement.
For example, research is needed to develop approaches for more quickly recovering from data breaches
and problematic releases. Remediation techniques might also provide the capabilities to correct ordelete erroneous data about individuals, exclude improperly used data, and effect a change in theprocessing systems that caused the privacy event. Research is also needed to develop new techniques toeffect redress, such as rendering the data useless, as well as mechanisms to delete or “forget”
information.

privacy technologies?
How could privacy-protecting and privacy-recovery technologies be integrated to create more
effective and efficient solutions?

3.7 Reduce privacy risks of analytical algorithms
Algorithms that analyze and predict human behavior and performance, detect fraud, or perform otherimportant functions have been used by government and business for decades. The operation ofpredictive algorithms can benefit or harm individuals by categorizing a person in ways that enhance orlimit his or her options and opportunities.
Increasingly, analytical algorithms are being combined with large-scale data sources, and systems are
acting upon the results of the algorithmic determination. “Analytical algorithms” are algorithms forprioritizing, classifying, filtering, and predicting. Their use can create privacy issues when theinformation used by algorithms is inappropriate or inaccurate, when incorrect decisions occur, when
there is no reasonable means of redress, when an individual’s autonomy is directly related toalgorithmic scoring, or when the use of predictive algorithms chills desirable behavior or encourages
other privacy harms.
There are gaps in public knowledge about the range of data-intensive analytical algorithms that are inuse, what they are used for, and their susceptibility to error and misuse. It is often unclear if suchalgorithms have a disparate impact on certain gender, age, racial, or economic groups even when thealgorithm does not explicitly use those attributes. Use of such algorithms for employment, housing,policing, and other critical areas potentially implicates Federal equal opportunity laws and demands
18

National Privacy Research Strategy

greater transparency. Indeed, the lack of transparency around companies providing consumer data for
credit and other eligibility determinations led to the adoption of the Fair Credit Reporting Act, passed in
1970. However, it is currently difficult, and sometimes infeasible, for those using these algorithms toknow if they are producing a disparate impact. Outcome-based studies have identified these issues in
the past, but such studies take substantial time and effort, and may not be feasible when an algorithm isre-trained on a weekly or daily basis—as might be done to customize the decisions of an algorithm using
current events.
Many anticipated uses of predictive algorithms require that the outcomes of the algorithms be
explainable for reasons of accountability, transparency, and auditing. In some cases, it may beappropriate (or legally required) for individuals to be able to control whether certain types of data areused in decision-making. For instance, the Equal Credit Opportunity Act of 1974 prohibits credit
discrimination on the basis of race, color, religion, national origin, sex, marital status, age, or because aperson receives public assistance. However, many analytical algorithms in use today provide little clarity
in these areas.
Research is needed to understand the current and planned usage of these algorithms, as well as todevelop methods to increase transparency and improve accountability when these algorithms are
employed. Improved capabilities are also needed to understand people’s concerns, the type and extent
of control that is feasible and how to present information to both application developers and end users
as new applications of predictive algorithms arise. Techniques are also needed to detect, correct, andredress errors or harm that these algorithms might cause.
Key research questions include:


In what ways do analytical algorithms and systems that act upon the results of the algorithms
adversely affect individuals or groups of people?
What types of concerns do individuals have with respect to analytical and predictive algorithms,
and what information do they need to address these concerns? How can this information beeffectively conveyed to an individual?
How can the provenance, accuracy, and quality of data used in making a decision or a prediction
about an individual or groups be assessed?
How can the compatibility between datasets and analytical algorithms be assessed?
What are the impacts on individuals or groups when analytical algorithms use erroneous or
inaccurate data?
How can the decisions or predictions made by analytical algorithms be measured and assessed
for compliance with legal requirements?
How can analytical algorithms be designed to provide increased transparency, accountability,
and auditing, and to minimize adverse effects on individuals or groups? What are practicablealgorithm discovery and intervention mechanisms for individuals, the government, andindustry?

19

National Privacy Research StrategyWhat are the impacts of analytical algorithms on individuals’ autonomy and agency (i.e., theability to make independent and free choices)? In what ways do analytical algorithms create astructure that determines, affects, or limits decisions by individuals?
How can new technologies and algorithms, and combinations of technologies and algorithms,
provide practical and theoretical privacy-preserving data analysis?

Addressing these questions will require a broad research agenda. In addition to research in machinelearning and statistics, this strategy will require human factors research in the interplay between people
and algorithms.

4. Executing the National Privacy Research Strategy
This strategy presents privacy research priorities based on a joint assessment by Federal agencies
participating in the Federal Networking and Information Technology Research and Development (NITRD)
Program. As a strategic plan, this document provides guidance to the Executive Branch, policymakers,
researchers, and the public in determining how to direct resources into activities that have the greatest
potential to generate the greatest impact. It is each agency’s responsibility to incorporate theseresearch priorities into its research plans and programs, drawing on its individual strengths and in thecontext of its mission.
The execution of the National Privacy Research Strategy vests in the Federal agencies, which develop
and execute R&D activities, based on their missions and capabilities. The NITRD Program coordinates
Federal research investments in various areas of IT through its interagency working groups. In particular,
the NITRD Program will ensure that Federal privacy research is well coordinated by helping agencies
understand each other’s activities, by supporting agencies in minimizing duplication and gaps,
promoting and sharing best practices, maximizing impact, by supporting multi-agency collaboration, andby considering how to align the overall NITRD privacy research portfolio with this strategy.
Privacy research funded under this strategy can have a broad range of effects. Research on current
practices in the information ecosystem can inform the public debate on privacy issues and provide
useful information to policymakers. Research that creates new privacy theory and models creates
intellectual frameworks that can help individuals understand privacy, guide the creation of privacy tools,
and serve as the basis for further theoretical development. Work on new privacy-enhancing
technologies creates prototypes and products that can be used to help society to realize the benefits of
networked information technology without sacrificing personal privacy.
Among the first steps in executing the strategy should be a comprehensive review of literature andstudies across sectors to assess existing knowledge relevant to the research priorities defined in thisplan. Identifying and connecting the variety of research and applied activities in privacy in the many
sectors and domains where such work is conducted would be a valuable contribution of the NPRS.

20

National Privacy Research Strategy

As part of the national strategy, funding agencies are strongly encouraged to create opportunities forresearchers to meet with potential users of the research and the public throughout the research process
to ensure that research remains aligned with real-world needs and requirements. These opportunities
can include “matchmaking” events for researchers to discuss their work, and for potential users to
discuss their needs and requirements, ensuring ongoing relationships between researchers, potential
customers, and the public, creating opportunities for testing prototypes on real data, and providing
governmental assistance for pilot studies and field-testing. Funders should encourage those submitting
proposals to have clear plans for technology transfer at the successful conclusion of a research project.
Funding agencies should also explicitly account for the multidisciplinary nature of privacy and enable
research that requires joint contributions from two or more disciplines.
While many privacy-preserving techniques and solutions are developed for a specific application, they
can frequently be applied in other areas or generalized to broader classes of problems. NITRD agencies
are therefore strongly encouraged to create or support the creation of catalogs, or other sharing
mechanisms, of privacy-preserving solutions so that such solutions can be shared among agencies andwith the public. To help ensure that new and better methods and tools are adopted, the government
may need to create incentives or requirements for adoption.

21

National Privacy Research Strategy

Appendix A: National Privacy Research Strategy Background
Efforts by the Federal Government to protect privacy of individuals are numerous including, forexample, the strict confidentiality provisions of the 1929 Census Act which made a disclosure of private
information by an agent of the Census Bureau a felony, punishable with up to 2 years of imprisonment.
Likewise, supporting and enabling privacy has been a key policy principle of this Administration. The
document Consumer Data Privacy in a Networked World: a Framework for Protecting Privacy andPromoting Innovation in the Global Digital Economy21 articulates the Administration’s policy on
consumer privacy, and the subsequent discussion draft of a legislative proposal22 suggests a pathforward to address privacy challenges in today’s information technology-driven world.
The technological challenges and opportunities in protecting privacy have received increased attention
as well. The President’s Council of Advisors on Science and Technology (PCAST) 2015,23 2013,24 and201025 reviews of the NITRD Program26 have identified challenges to personal privacy in the digital era asa significant impairment undermining societal benefits from large-scale deployments of networking andIT systems. Underscoring the impairment of societal benefits, a national survey27 sponsored by the
National Telecommunications and Information Administration (NTIA) revealed that 45% of online
households have been deterred from participating in online activities such as conducting financialtransactions, buying goods or services, or expressing opinions on controversial issues via the Internet,
due to concerns about online privacy and security.
Consequently, PCAST has called upon Federal research agencies to create a multi-agency initiative
focused on developing scientific and engineering foundations for protecting privacy, which could thenbe the basis for new technologies and solutions in this space.

National Privacy Research Strategy

In 2014, the National Coordination Office (NCO) for the NITRD Program surveyed Federal agencies toassess the size and scope of Federally-funded privacy research activities. It identified investments ofapproximately $80 million/year in R&D activities across a broad spectrum of topics and interests related
to privacy. The resulting document, Report on Privacy Research within NITRD,28 provides a summary of
the survey. The review showed that there are many innovative research projects within NITRD that areclassified by their agencies as relevant to a broad range of privacy challenges. At the same time, thesurvey demonstrated the need for an interagency research framework that will help maximize research
impact and ensure the coordination of R&D investments in this area.
Consequently, NITRD began examining both Governmental and societal needs in privacy-enhancing
technologies and began defining a framework for research to guide Federal R&D investments in thisarea. In September 2014, the NITRD Cyber Security and Information Assurance Research andDevelopment Senior Steering Group (CSIA R&D SSG) convened a task group of representatives fromvarious agencies, including Air Force Office of Scientific Research (AFOSR), Census Bureau, Defense
Advanced Research Projects Agency (DARPA), Department of Homeland Security (DHS), Department ofEnergy (DOE), Federal Bureau of Investigation (FBI), Federal Trade Commission (FTC), Intelligence
Advanced Research Projects Activity (IARPA), Office of the Director of National Intelligence (ODNI),
Office of Naval Research (ONR), Office of the Secretary of Defense (OSD), Office of Science andTechnology Policy (OSTP), National Institute of Standards and Technology (NIST), National Institutes of
Health (NIH), National Security Agency (NSA), and the National Science Foundation (NSF). CSIA R&D SSG
tasked the group with developing a strategy to establish objectives and prioritization guidance forFederally-funded privacy research, providing a framework for coordinating R&D in privacy-enhancing
technologies, and encouraging multi-disciplinary research that recognizes the responsibilities of theGovernment and the needs of society, as well as enhances opportunities for innovation in the digital
realm.
The task group reviewed agency needs and existing research activities related to privacy. The group also
obtained public input in three ways: (1) by issuing a Request For Information published in the Federal
Register in September 2014, (2) by hosting a National Privacy Research Strategy Workshop in Arlington,
Virginia in February 2015, and (3) by reviewing the report Towards a Privacy Research Roadmap for theComputing Community prepared by the Computing Community Consortium in May 2015. Details forthese engagements are available on the NITRD website.29

Appendix B: Legal and Policy Context for Privacy
The U.S. privacy regulatory structure encompasses three basic areas: regulation of commercial entities,
government delivery of services, and national security and law enforcement. Each of these areas has along history of law and policymaking aimed at protecting individual privacy from intrusions by private
and governmental actors. These existing laws and policy approaches have begun the work of developing
a conceptual basis for privacy, articulating basic expectations and values, and establishing principles
such as use limitation and access.
When considering privacy in the public sector, the Fair Information Practice Principles (FIPPs)30 haveshaped Federal laws, regulations, and guidance. The Privacy Act of 1974 is the foundation for privacy
protection at the Federal level, and there are similar statutes among the states. The Privacy Act
establishes obligations for Federal agencies to limit information collection and maintain accurate
information about systems of records, about conditions for disclosure, about provisions for individuals’
access to their information, as well as requirements for how data can be shared among separate
systems of records. The Privacy Act is often augmented at the agency level through additional statutes
or regulations that specifically protect materials such as tax information, census filings, student
information, and other kinds of information and, in the process, reflecting various FIPPs principles suchas use limitation, purpose specification, security safeguards, and accountability. “Appendix-J” of NIST
Special Publication 800-53, Security and Privacy Controls for Federal Information Systems andOrganizations,31 describes 25 different privacy controls that have been implemented by the Federal
Government, providing the agencies with supplemental guidance and the appropriate legislative
justification for each one. Based on the FIPPs and reflecting best practices, the privacy control catalog isintended to complement and augment Federal information security programs, and reflects the everincreasing importance of the intersection of privacy and information security programs.
Regulation of commercial actors has become an area of tremendous importance in the U.S. privacy
structure as advances in IT have led to novel uses of personal information across a variety of industries.
Whereas the privacy laws of many other nations protect all personal data broadly, the U.S. consumer
data protection structure has no comprehensive statutory protection specifically addressing privacy

across all sectors. Instead, the U.S. approach is sectoral, with most data privacy statutes only applying to
specific sectors such as health care, education, communications, and financial services. The sectoral
approach permits controls tailored to particular context, but can also leave gaps. For instance, between
1974 and 2004, the United States passed legislation providing significant privacy protections for
consumer information in government databanks (1974),32 educational records (1974),33 financial records(1978),34 cable television records (1984),35 e-mail (1986),36 video rental records (1988),37 unwanted
phone calls (1991),38 driver’s license records (1994),39 healthcare records (1996),40 telecommunications
data (1996),41 information collected from children online (2001),42 and satellite television records(2004).43 In each of these cases, Congress protected information that was collected during the course ofobtaining services commonly used by citizens. In addition, the Federal Trade Commission (FTC) can takeaction against companies engaged in “unfair or deceptive” privacy practices where they, for example,
make false or misleading claims about privacy or data security or fail to employ reasonable security
measures and, as a result, cause or are likely to cause substantial consumer injury.
In the United States, self-regulation has played an important role in helping to police commercial
markets. Self-regulation through trade associations and certification programs can adapt more quickly
and in a more tailored fashion than government regulation. Self-regulation is a market-based solutionthat can quickly reward players who deliver products and policies responsive to consumer needs anddesires. In addition, self-regulation can handle a variety of tasks—creating rules, playing a role inenforcement, and/or being involved in adjudication. The notice-and-choice model, based on the right toknow about what data is collected and to consent (or withhold consent) from its collection and use,encourages companies to develop privacy policies describing their information collection and use
practices so that individuals can make informed choices. Some critics claim, however, that selfregulation, and in particular the notice-and-choice model on which it relies, has failed to provide
meaningful protection. Instead of providing transparency and empowering individuals with market
choices, critics argue that this model has led to long, incomprehensible privacy policies that individuals
do not read and have difficulty understanding and are often substantially more expansive than theactual and expected use of the data. In extreme cases, notice-and-choice has allowed players to engage
in aggressive data sharing practices as long as the practices are documented and the consumers give
their consent.

In keeping with its mission of promoting free market competition while preventing “deceptive or unfair
practices,” the FTC has established itself as a backstop in the self-regulatory scheme. If a company
deceives consumers about its compliance with a self-regulatory scheme, the FTC can take action alleging
a deceptive practice under the FTC Act. State attorneys general have similar consumer protection
authorities and play an important role in collaboration with the FTC.
In 2012, the Administration released a white paper entitled Consumer Data Privacy in a Networked
World: A Framework for Protecting Privacy and Promoting Innovation in the Global Digital Economy.44
This paper described a four-point strategy for protecting consumer privacy: the creation of a Consumer
Privacy Bill of Rights (CPBR); fostering multistakeholder processes to develop enforceable codes ofconduct; strengthening FTC enforcement; and improving global interoperability. The CPBR laid out
general principles, including respect for context and individual control, among others, that afforded
companies discretion in how they were implemented. The Administration recommended legislation to
codify the CBPR and implement a process for the creation of codes of conduct through voluntary
participation in multistakeholder processes. The proposed legislation would set forth a process throughwhich the FTC could grant safe harbor status to these codes. Finally, the white paper laid out the goalsof increasing global interoperability of privacy enforcement. This framework was put forward inactionable form in 2015 in the Administration’s Consumer Privacy Bill of Rights Act Discussion Draft.45
While this draft was not taken up by Congress, the Administration continues in its belief that it presents
the best way forward to both protect consumer privacy and trust while maintaining the flexibility
needed to promote innovation and growth.
The third area that has been a significant focus of privacy law and policymaking in the United States islaw enforcement and national security. Today, law enforcement and intelligence agencies have theability to collect, connect, and analyze a wide array of data to create a “virtual picture” of individuals to
help with solving crimes, preventing attacks, and tracking terrorists.
Recognizing the privacy concerns that such activities can raise, these activities are bound by the rule oflaw as well. The legal constraints include Constitutional protections such as First Amendment protection
for freedom of speech and Fourth Amendment prohibition on unreasonable searches and seizures. In
addition, law enforcement and intelligence agencies are also bound by laws such as the Electronic
Communications Privacy Act (ECPA), the Privacy Act, and the Foreign Intelligence Surveillance Act (FISA).
Establishing an effective approach to privacy protection that allows individuals to realize the benefits of
information technology without compromising their privacy has been difficult—in part, because ofdifferences in individuals’ understanding, attitudes, expectations, and behavior, as well as the rapid paceof change in technology. By focusing research efforts on these challenges and prioritizing the translation
