Episode 27 — Apply purpose limitation so data use stays aligned with promises and approvals (Domain 2C-7 Purpose Limitation)

This episode explains purpose limitation as a governance-and-technology pairing that prevents silent expansion of how data is used, which is a frequent source of privacy failures and exam scenarios. You’ll learn how to define purpose in operational terms, how to document it in inventories and processing records, and how to enforce it through access patterns, service boundaries, and approval gates. We’ll walk through examples like using support tickets to train models, reusing sign-up data for advertising, or sharing customer data with a partner for “enhancement,” showing how secondary use can be noncompliant even when security is strong. You’ll also practice choosing the next best action when teams propose new uses, focusing on assessment triggers, updated notices, renewed consent when needed, and technical controls that prevent unauthorized repurposing.
