Artificial intelligence is no longer a “future trend” in DSAR handling. By 2025, it is already reshaping how universities, NHS bodies, local authorities and corporate organisations search, filter, redact and deliver personal data.

At the same time, regulators have made one thing clear: AI can support DSAR compliance, but it cannot dilute it.
The Data (Use and Access) Act 2025 (DUAA) and the ICO’s renewed focus on AI mean DSAR teams must demonstrate two things:

1. They are using AI to work more effectively.

2. They remain fully accountable for every search, redaction and disclosure.

This blog explores how AI is transforming DSARs in practice—without replacing human judgement.

1. A New DSAR Reality: High Volume, High Complexity

Today’s DSAR environment brings greater pressure than ever. Teams now face:

• long email chains

• Teams/Slack messages

• PDFs, scans and screenshots

• mixed-format data across many systems

• increased complaints

• DUAA-driven expectations around evidence and documentation

AI has become a practical necessity, not to cut corners, but to help teams maintain accuracy, consistency and compliance.

2. The Legal Baseline: DUAA and ICO Expectations

DUAA doesn’t change individuals’ rights. It clarifies what organisations must do.

Key expectations include:

• DSAR searches must be “reasonable and proportionate”.

• Teams must justify why systems were included or excluded.

• AI use must be transparent, fair, accurate and supervised by humans.

• AI cannot be the final decision-maker.

In short: AI is welcome, but only as part of a transparent, auditable DSAR workflow.

3. How AI Is Transforming DSAR Search

AI has shifted DSAR search from keyword-based guesswork to meaning-based, context-aware retrieval.

Examples of AI-driven search include:

• natural language queries (e.g., “Find all discussions about the grading appeal for this student”)

• entity recognition (names, IDs, roles, case references)

• clustering related documents

• concept-based search across email, Teams, SharePoint, HRIS, clinical notes and archives

• cross-system correlation without manual effort

A practical example:
If a university receives a DSAR referencing “exam misconduct and academic appeal,” AI can map the requester’s footprint across the VLE, disciplinary systems, exam boards, staff mailboxes and SharePoint folders used during the case. Instead of searching every academic mailbox, DSAR teams only search where data is genuinely likely to be—exactly what DUAA expects.

4. Redaction: AI Handles the Volume, Humans Handle the Judgement

AI now supports redaction by flagging:

• third-party names

• special category data

• student IDs / NHS numbers

• sensitive clinical or HR notes

• privileged material

But one risk is clear: over-redaction.

DUAA expects organisations to balance the requester’s right of access with third-party privacy. AI can highlight potential issues, but humans must confirm, adjust and justify each decision.

A common scenario:
In NHS case files, AI may correctly pick up patient identifiers—but also over-flag medical terms as sensitive. Reviewers must ensure information is not withheld unnecessarily.

5. How AI Is Changing DSAR Triage

AI is also transforming the first stage of DSAR handling: recognising and categorising incoming requests.

Modern triage can:

• detect whether an email or form is actually a DSAR

• extract the requester’s identity

• identify their relationship with the organisation

• highlight keywords linked to litigation, safeguarding or whistleblowing

• route complex cases to senior handlers automatically

For example, if a council receives a DSAR containing terms like “child protection meeting” or “social worker visit,” AI can immediately flag safeguarding indicators and send the case to the right reviewers. However, teams must check regularly for bias and misclassification.

6. The Risks: AI Helps, But It Can Still Go Wrong

Organisations must remain alert to AI limitations, including:

• hallucinations (invented context or summaries)

• misclassification of DSARs

• under- or over-redaction

• bias in how requests are prioritised

• workload distortions that affect timelines

DUAA gives flexibility, but accuracy remains non-negotiable.

7. Documentation and Explainability: The 2025 Standard

The ICO now expects transparent, human-readable explanations when AI is used in DSAR handling.

Modern DSAR teams maintain:

• search logs (systems, terms, dates, models used)

• redaction logs (AI flags, human overrides, reasoning)

• model versions and sampling results

• proportionality notes

• human approval records

A corporate example:
“AI clustered 2,800 emails into three themes. Reviewers confirmed personal data in 340 emails; remaining clusters contained no requester data.”
That single note can significantly strengthen a response if challenged by the requester or ICO.

8. What an AI-Enabled DSAR Workflow Looks Like in Practice

Across sectors, a 2025 DSAR workflow typically looks like this:

1. AI identifies incoming DSARs and extracts context.

2. Triage assigns risk level (HR dispute, clinical concern, safeguarding, whistleblowing).

3. AI-assisted search suggests likely systems and data locations.

4. Humans approve the search scope and document proportionality.

5. AI-assisted redaction flags sensitive data.

6. Reviewers confirm or override each suggestion.

7. The DSAR file is automatically logged with evidence.

8. Deadlines and pause periods are monitored automatically.

Automation does the heavy lifting. Humans stay in control.

9. The Bottom Line: AI Won’t Replace DSAR Teams—It Redefines Them

2025 DSAR compliance is built on:

• smarter, concept-based searches

• evidence-led proportionality

• consistent, explainable decisions

• human oversight at every stage

AI helps achieve speed, accuracy and defensibility. DUAA requires teams to show how they got there.

AI isn’t replacing DSAR professionals—it’s giving them the precision and structure they’ve needed for years.
