**GDPR and CCPA** GDPR and CCPA are data protection regulations requiring consent data minimization right to deletion and privacy by default for AI systems. GDPR applies to EU residents CCPA to California residents. Key requirements include obtaining explicit consent for data collection providing transparency about data usage enabling data access and deletion and implementing privacy by design. For AI systems this means minimizing personal data in training sets anonymizing or pseudonymizing data providing explanations for automated decisions and enabling model unlearning to delete user data. Challenges include removing data from trained models explaining black-box decisions and balancing privacy with model performance. Techniques include differential privacy adding noise to protect individuals federated learning training without centralizing data and synthetic data generation. Non-compliance risks include fines up to 4 percent of revenue and reputational damage. Privacy-preserving ML is essential for compliant AI systems. Organizations must implement data governance audit trails and privacy impact assessments. GDPR and CCPA drive adoption of privacy-enhancing technologies in AI.
