Differential Privacy Patterns(DPP)
Privacy-preserving data processing with mathematical privacy guarantees
Complexity: highSecurity & Privacy Patterns
๐ฏ 30-Second Overview
Pattern: Privacy-preserving data processing with mathematical privacy guarantees through controlled noise injection
Why: Provides formal privacy guarantees, enables safe data sharing, supports regulatory compliance, and maintains statistical utility
Key Insight: Calibrated noise + sensitivity bounds + privacy budget โ mathematically guaranteed privacy
โก Quick Implementation
1Privacy Budget:Define epsilon (ฮต) privacy parameter
2Sensitivity Analysis:Calculate query sensitivity bounds
3Noise Mechanism:Apply Laplace/Gaussian noise injection
4Composition:Track cumulative privacy expenditure
5Utility Validation:Verify statistical utility preservation
Example: privacy_budget โ sensitivity_analysis โ noise_injection โ composition_tracking โ utility_validation
๐ Do's & Don'ts
โ
Set appropriate epsilon values for privacy requirements
โ
Use proven noise mechanisms (Laplace, Gaussian, Exponential)
โ
Track privacy budget expenditure across all queries
โ
Apply post-processing invariance for utility improvements
โ
Validate statistical utility after noise injection
โUse the same noise instance across multiple queries
โExceed privacy budget without proper composition
โIgnore sensitivity bounds for unbounded queries
โApply differential privacy to already aggregated data
โSkip formal privacy analysis for custom mechanisms
