Data Privacy Impact Assessment

Read the assigned provisions, attempt the diagnostics, then compare your reasoning with the model responses.

Today’s topicData Privacy Impact Assessment
Estimated time90-120 minutes
Primary Act references.28
Guide referenceGuide pp.5, 9 and Assessment 2

Learning Objectives

Explain and apply high-risk screening.

Explain and apply necessity and proportionality.

Explain and apply risks to rights.

Explain and apply mitigation and residual risk.

Explain and apply prior consultation.

Diagnostic Assessment

Attempt these questions before reading the model responses.

1. What is the principal compliance issue addressed by s.28?

Show model response

Model response: It is data privacy impact assessment. The analysis should focus on high-risk screening and the connected statutory conditions.

2. Identify two concepts that must be considered when analysing data privacy impact assessment.

Show model response

Model response: Any two of the following are relevant: high-risk screening, necessity and proportionality, risks to rights, mitigation and residual risk.

3. Why should a DPO cite the exact section instead of relying only on a general privacy principle?

Show model response

Model response: The section contains the controlling conditions, limits and exceptions. A general principle may guide analysis but cannot replace the specific statutory test.

4. What evidence should an organisation retain when applying s.28?

Show model response

Model response: It should retain the facts considered, the statutory test, the decision, supporting records, responsible approval and any review or corrective action.

5. How should the organisation respond when the uploaded sources do not resolve a material detail?

Show model response

Model response: It should record the limitation and avoid inventing a requirement. The DPO should return to the full statutory wording and seek current authoritative material when permitted.

Structured Lesson

LEGAL RULE: The controlling statutory material for this lesson is s.28. Apply its precise language, conditions and exceptions to the facts.

1. High-Risk Screening

High-risk screening is a central issue for this study day. The DPO should locate the exact statutory conditions in s.28, apply them to the particular processing activity and retain evidence supporting the conclusion.

The Guide’s workflow moves from high-risk screening through necessity, proportionality, risk, safeguards, residual risk, approval and possible consultation with the Commission.

2. Necessity And Proportionality

Necessity and proportionality is a central issue for this study day. The DPO should locate the exact statutory conditions in s.28, apply them to the particular processing activity and retain evidence supporting the conclusion.

The Guide’s workflow moves from high-risk screening through necessity, proportionality, risk, safeguards, residual risk, approval and possible consultation with the Commission.

3. Risks To Rights

Risks to rights is a central issue for this study day. The DPO should locate the exact statutory conditions in s.28, apply them to the particular processing activity and retain evidence supporting the conclusion.

The Guide’s workflow moves from high-risk screening through necessity, proportionality, risk, safeguards, residual risk, approval and possible consultation with the Commission.

4. Mitigation And Residual Risk

Mitigation and residual risk is a central issue for this study day. The DPO should locate the exact statutory conditions in s.28, apply them to the particular processing activity and retain evidence supporting the conclusion.

The Guide’s workflow moves from high-risk screening through necessity, proportionality, risk, safeguards, residual risk, approval and possible consultation with the Commission.

5. Prior Consultation

Prior consultation is a central issue for this study day. The DPO should locate the exact statutory conditions in s.28, apply them to the particular processing activity and retain evidence supporting the conclusion.

The Guide’s workflow moves from high-risk screening through necessity, proportionality, risk, safeguards, residual risk, approval and possible consultation with the Commission.

GUIDE GUIDANCE: The Guide assigns Day 10 to data privacy impact assessment and requires study of s.28. Its practical emphasis is high-risk screening, necessity and proportionality, risks to rights.
TUTOR EXPLANATION: Use a five-step analysis: identify the processing facts, confirm the actor and role, locate the controlling section, test every condition and exception, then document the decision and evidence.

Nigerian Scenario and Model Analysis

A public university begins a project involving staff or customer personal data. The project raises questions about high-risk screening and necessity and proportionality. Identify the controller, any processor, the data subjects, likely personal data, the required statutory analysis under s.28, key risks and the compliance evidence that should be retained.

Show model response

Model analysis: The organisation determining why and how the project operates is normally the controller. A vendor acting only on documented instructions is normally a processor. Staff or customers are the data subjects. The DPO should inventory the data, apply s.28 to the stated purpose, document the decision, assign controls and retain evidence. The final conclusion depends on the precise facts and statutory conditions.

Lesson Summary

Day 10 establishes how a DPO should understand and apply data privacy impact assessment. The legal starting point is s.28. The main operational lesson is to connect high-risk screening, necessity and proportionality, risks to rights to documented facts and evidence.

Ten Key Terms

TermWorking definition
ControllerA person or body that determines the purposes and means of processing personal data.
ProcessorA person or body that processes personal data on behalf of a controller.
Data SubjectThe identified or identifiable individual to whom personal data relate.
Personal DataInformation relating to an identified or identifiable individual.
ProcessingAn operation performed on personal data, including collection, use, storage, disclosure or deletion.
DpiaA prior assessment of high-risk processing, its necessity, risks, safeguards and residual risk.
Residual RiskRisk remaining after planned safeguards and mitigation measures are applied.
AccountabilityResponsibility for compliance and the ability to demonstrate it with evidence.
SecurityRisk-appropriate technical and organisational protection for personal data.
ProcessingAn operation performed on personal data, including collection, use, storage, disclosure or deletion.

Definitions are paraphrased for study. Check section 65 and the relevant operative provision for controlling wording.

Five Revision Questions and Responses

1. What provisions govern this lesson?

Show model response

Response: s.28

2. What are the principal concepts?

Show model response

Response: high-risk screening, necessity and proportionality, risks to rights, mitigation and residual risk, prior consultation.

3. What is the correct source hierarchy?

Show model response

Response: The Act is primary authority. The Guide supports learning and professional application. Tutor explanation assists interpretation without creating new law.

4. What is the central evidence requirement?

Show model response

Response: Record the facts, applicable test, conclusion, approval, controls and review trigger.

5. What common error should be avoided?

Show model response

Response: Do not assume a broad principle answers the issue. Test the exact conditions and exceptions in the assigned section.
