Introduction to Privacy-Preserving ML

🎯 The Privacy Challenge

Machine learning requires large datasets, but data often contains sensitive personal information. Privacy-preserving ML enables training models without exposing individual data points.

⚠️
Critical Trade-off

More privacy protection typically reduces model accuracy

🚨 Real-World Privacy Concerns

🏥

Medical Records

Patient data for disease prediction must remain confidential

💳

Financial Data

Transaction histories for fraud detection contain PII

📱

Mobile Devices

Keyboard predictions trained on personal messages

🔍

Search Queries

User searches reveal sensitive interests and behaviors

🛡️ Privacy Attack Scenarios

Model Inversion

Reconstruct training data from model parameters or predictions

Membership Inference

Determine if specific data was in the training set

Attribute Inference

Infer sensitive attributes not used during training

🔑 Key Privacy Techniques

Differential Privacy

Add calibrated noise to protect individual contributions

Federated Learning

Train on decentralized data without sharing raw data

Homomorphic Encryption

Compute on encrypted data without decryption

Secure MPC

Multiple parties compute without revealing inputs
