Identify-P Function

Also known as: ID-P, Identify-P, Identify (Privacy) Function

Simply put

Identify-P is one of the core Functions in the NIST Privacy Framework. It focuses on building an organization's understanding of the privacy risks that data processing activities can create for individuals. In practice, this means knowing what data is being processed, how, and where privacy risks may arise, so those risks can be managed.

Formal definition

Identify-P is a Function within the NIST Privacy Framework, defined as developing the organizational understanding necessary to manage privacy risk for individuals arising from data processing. As a foundational Function, it emphasizes establishing awareness of an organization's data processing ecosystem, systems, and associated privacy risks, providing the basis on which other Framework Functions (such as governance, control, and communication activities) operate. The NIST Privacy Framework is voluntary, non-binding guidance and does not itself impose legal obligations; Identify-P is one component of a broader privacy risk management approach rather than a complete program. Organizations should confirm implementation details against NIST Privacy Framework primary documentation, and note that specific privacy obligations vary by jurisdiction and may require qualified legal counsel.

Why it matters

Identify-P establishes the factual foundation on which every other part of a privacy risk management effort depends. An organization cannot govern, control, or communicate about privacy risks it has not first identified. By developing an understanding of what data is processed, how and where processing occurs, and how those activities may create risk for individuals, Identify-P gives compliance, privacy, and program teams the visibility needed to make informed decisions rather than assumptions. Without this understanding, downstream controls are likely to be misaligned with the actual data processing environment.

The Function matters because privacy risk arises from data processing itself, not only from security breaches. Mapping data flows, inventorying processing activities, and characterizing the associated privacy risks helps surface exposures that might otherwise remain invisible until an incident or regulatory inquiry forces attention to them. Because the NIST Privacy Framework is voluntary and non-binding, Identify-P does not by itself satisfy any legal requirement, but the understanding it produces can support an organization's broader efforts to meet obligations that vary by jurisdiction.

Readers should treat Identify-P as one component of a larger privacy risk management approach rather than a complete program, and should recognize that carrying out these activities is intended to support, not guarantee, effective privacy risk management. Specific privacy obligations vary by jurisdiction and may require qualified legal counsel; this entry is educational and not a substitute for professional advice.

Who it's relevant to

Privacy program managers

Those responsible for building or maintaining a privacy risk management effort rely on Identify-P to establish the understanding of data processing activities on which governance, control, and communication activities depend. It helps them scope where privacy risks to individuals may arise before selecting controls.

Compliance and legal teams

Compliance officers and legal counsel use the understanding produced under Identify-P to inform how the organization approaches privacy obligations. Because the NIST Privacy Framework is voluntary and does not impose legal obligations, and because privacy requirements vary by jurisdiction, these teams should treat Identify-P outputs as input to, not a substitute for, jurisdiction-specific legal analysis.

Data governance and IT staff

Personnel who inventory systems, map data flows, and characterize processing activities carry out much of the practical work of Identify-P. Their understanding of the data processing ecosystem provides the foundation the other Framework Functions build upon.

Learning and development staff

Those designing awareness or training content can use Identify-P to help staff understand that privacy risk arises from data processing itself and that identifying such risk is a distinct, foundational activity within a broader privacy risk management approach, not a complete program on its own.

Inside ID-P

Identify-P Function

One of the core Functions of the NIST Privacy Framework Version 1.0. It is intended to help an organization develop the organizational understanding needed to manage privacy risk for individuals arising from data processing. It is a foundational, non-binding governance concept, not a training module or a complete compliance program. The Privacy Framework is a voluntary tool published by NIST for U.S. federal purposes and broader use; it does not carry the force of law.

Inventory and Mapping

Activities within Identify-P concerned with understanding what data are processed, the systems and third parties involved, and how data flow through the organization. This category supports awareness of processing activities so that privacy risk can be assessed. Exact category and subcategory labels should be confirmed against the primary NIST Privacy Framework document.

Business Environment

Elements addressing how the organization's role, mission, and stakeholders relate to privacy risk, so that data processing is understood in context. This supports prioritization of privacy risk management efforts.

Risk Assessment (Privacy)

The component focused on identifying and analyzing privacy risks to individuals that can result from data processing. It informs, but is distinct from, the response and monitoring activities found in other Functions of the framework.

Data Processing Ecosystem Risk Management

Activities addressing the identification and understanding of privacy risks associated with third parties, vendors, and partners involved in data processing. Precise subcategory wording should be verified against the source document.

Relationship to Other Functions

Identify-P is one Function among the framework's set of core Functions and is intended to work alongside them. It represents the understanding and foundation stage and does not by itself constitute a complete privacy program; response, governance, and control activities reside in the other Functions.

Common questions

Answers to the questions practitioners most commonly ask about ID-P.

Is the Identify-P Function an undefined or unofficial term?

No. The Identify-P Function is expressly defined in the NIST Privacy Framework Version 1.0 as one of the core Functions of that framework. It is an established element of a recognized, publicly available privacy risk management resource, not an ambiguous or fabricated term. Note that the NIST Privacy Framework is a voluntary, non-binding tool and does not carry the force of law; organizations adopt it at their discretion.

Does the "P" in Identify-P relate to p-values or statistical significance?

No. The "P" stands for Privacy, distinguishing this Function from the Identify Function in the NIST Cybersecurity Framework. It has no connection to p-values, statistical hypothesis testing, or any quantitative significance measure. Any association with statistical p-value concepts reflects a naming coincidence and should be disregarded when interpreting this term.

How does the Identify-P Function fit within a broader privacy or compliance program?

The Identify-P Function is one component of the NIST Privacy Framework and is intended to help an organization develop the understanding needed to manage privacy risk to individuals arising from data processing. It supports, but does not by itself constitute, a complete privacy or compliance program. Organizations generally pair it with the framework's other Functions and with distinct program elements such as policies, training, and monitoring. Implementation and effectiveness depend on organizational context.

What kinds of activities does the Identify-P Function typically encompass?

As defined in the NIST Privacy Framework Version 1.0, the Identify-P Function is generally associated with developing an organizational understanding of data processing and its associated privacy risks. This is intended to support informed decisions later in the framework. Because the framework is principles-based and voluntary, organizations tailor the specific activities to their own risk profile rather than following a prescriptive checklist. Practitioners should consult the primary NIST document for the precise Categories and Subcategories.

Who in an organization is typically responsible for carrying out the Identify-P Function?

Responsibility usually spans several roles, potentially including privacy officers, compliance and legal teams, data governance staff, and business owners of data processing activities. The NIST Privacy Framework does not mandate a specific assignment of responsibility, so organizations determine ownership based on their structure and risk. Where activities touch legal obligations that vary by jurisdiction, qualified legal counsel should be involved; this entry is educational and not a substitute for professional advice.

How should implementation of the Identify-P Function be documented and reviewed?

Because the framework is voluntary and principles-based, it does not prescribe documentation formats or review cycles. Organizations commonly document their understanding of data processing and associated privacy risks in a manner that supports later decision-making and periodic reassessment. Documentation and review practices should be confirmed against the organization's own governance requirements and any applicable legal obligations, which vary by local law.

Common misconceptions

Identify-P is a cybersecurity Function or the same as the NIST Cybersecurity Framework's Identify Function.

Identify-P belongs to the NIST Privacy Framework and is oriented to privacy risk to individuals from data processing. While the Privacy Framework is structured to be compatible with the Cybersecurity Framework, they address distinct risk domains and should not be treated as interchangeable. The '-P' designation signals its privacy orientation.

Adopting the Identify-P Function is a legal requirement that ensures regulatory compliance.

The NIST Privacy Framework is a voluntary, principles-based tool, not a law or binding regulation. Using Identify-P may support an organization's privacy risk management but does not by itself demonstrate compliance with any specific statute, and it provides no guarantee of legal protection. Applicable obligations vary by jurisdiction and should be confirmed with qualified legal counsel.

Completing the Identify-P Function means an organization has a complete privacy program.

Identify-P is one Function among several and represents the foundational understanding stage. A functioning privacy program also depends on the other Functions and on implementation quality; Identify-P alone does not establish controls, responses, or ongoing monitoring.

Best practices

Confirm the exact Function, Category, and Subcategory labels against NIST Privacy Framework Version 1.0 as the primary source before using them in training or documentation.

Build and maintain a current inventory and mapping of data processing activities, systems, and third parties as the basis for Identify-P work.

Treat Identify-P as the understanding-and-foundation stage, and explicitly connect it to the other framework Functions rather than presenting it as a standalone program.

Frame Identify-P as a voluntary, principles-based tool in materials, and avoid implying it satisfies specific legal obligations or guarantees compliance.

Engage qualified legal counsel to map Identify-P activities to jurisdiction-specific privacy laws, since applicable requirements vary by location.

Distinguish Identify-P from the NIST Cybersecurity Framework's Identify Function in training to prevent conflation of privacy and security risk domains.
