PERSONAL DATA REVIEW · Workflow idea

Make a working copy of a data file with personal details removed.

When a new CSV file is received, identify columns that may hold direct identifiers such as names, email addresses, or phone numbers. Prepare a separately named copy without those columns, keep the original intact, and have a responsible data owner verify the result before it is shared or used.

01 / The starting point

A clear request.
A useful direction.

A CSV file submitted for a defined data-minimization task

“Identify columns that may contain personal identifiers, prepare a separate cleaned copy, and hold it for a privacy review before use.”
An example request · Make it specific to your team.

02 / The work

5 tasks.
One useful outcome.

Helps teams reduce direct personal details in a working data copy while preserving the source file for review.

  1. Select the file for a defined purpose

    Confirm the file is appropriate to review and identify why a reduced-detail copy is needed.

  2. Identify columns that may contain direct identifiers

    Look for fields such as names, email addresses, or phone numbers and flag uncertain columns for a person.

  3. Prepare a separate cleaned copy

    Remove the identified columns from a new copy while preserving the original file unchanged.

  4. Compare the original and proposed copy

    Check whether identifiers remain, whether necessary context was lost, and whether the output is suitable for its intended use.

  5. Approve access and use with a data owner

    Have a responsible reviewer approve the exact copy and its recipients; do not describe it as anonymous without an appropriate assessment.

03 / The result

Something useful.
Something to build on.

A proposed copy with suspected identifier columns removed, accompanied by the unchanged original for verification.

The handoff

A proposed copy with suspected identifier columns removed, accompanied by the unchanged original for verification.

Keep in mind

A column-based check can miss identifying details or remove information needed for the task. Do not treat the result as proof that a file is anonymous or compliant. Have a privacy or data owner inspect the original and cleaned copy, confirm the intended use and access, and approve sharing.

04 / Make it yours

Set the brief.
Set the standard.

A few choices shape the work around your team.

Define eligible files and purpose

Choose the file types and approved uses for a reduced-detail copy.

Set personal-data review guidance

List identifiers and other sensitive fields that need attention and identify who handles uncertain cases.

Choose protected storage and access

Keep originals and proposed copies in approved locations with access limited to people who need them.

Test clear and difficult examples

Review files with different column names, missing headings, and unexpected personal details before relying on the process.
