Purpose Limitation

Purpose limitation is a fundamental principle requiring organizations to use personal data only for the specific purposes disclosed when that data was collected. This constraint prevents scope creep and unauthorized secondary uses, creating clear boundaries around how customer, employee, and third-party information can be processed. For enterprise AI governance, purpose limitation matters because machine learning systems often create pressure to repurpose datasets for new applications, and violating this principle can trigger regulatory violations under GDPR, CCPA, and similar privacy frameworks while also eroding stakeholder trust.

Meta's Invasive Prompt Incident Exposes Runtime Data Minimization Gap

Meta's AI assistant generated suggested prompts that identified children in a user's video and aggregated personal information from historical posts and family members' accounts. Meta acknowledged the problem, calling it a failure to 'hit the mark,' and applied fixes to prevent the system from suggesting prompts on personal topics. The incident illustrates a structural gap between data minimization policies and what AI systems actually do with available contextual data at runtime.
