Data Policy: K-Anonymization

Use Case: Employee Survey Data

Overview

A major healthcare organization regularly conducts employee surveys and needs to anonymize respondents’ data (stored in Snowflake) so it can be distributed to executives and line managers through PowerBI dashboards.

Challenge/Problem

Anonymizing the data (while preserving utility for analysts) has been a challenge.

Solution

Data owners can use Immuta’s k-anonymization policies to balance data utility with respondent privacy.
