This chapter covers
- When GenAI privacy fails in practice.
- Four pillars of data protection in GenAI
- Practical steps to reduce risks in each pillar
- How deployment posture changes privacy risks
- What evidence regulators look for
Let’s take this hypothetical scenario: when Elena Rodriguez filed her insurance claim with ElectraMotors, she had no idea that her conversation would be stored, analyzed, and eventually used in ways she never consented to. Six months later, when she called to dispute an unrelated billing issue, the chatbot greeted her by name and referenced details from a claim 10 years ago; details she hadn’t mentioned. Worse, some of what it “remembered” was wrong: it claimed she had a prior claim for a rear collision that never happened. Elena’s experience illustrates a new class of privacy failure that traditional data protection frameworks were never designed to handle.
