Zeph - Cryptographic Enforcement of End-to-End Data Privacy

Explore a conference talk on Zeph, a system that cryptographically enforces end-to-end data privacy in large-scale data analytics frameworks. Learn how Zeph allows users to set and enforce privacy preferences on their data, ensuring compliance with privacy policies through real-time, privacy-adhering data transformations. Discover the hybrid cryptographic protocol behind Zeph's privacy-preserving capabilities and its implementation on Apache Kafka. Understand the system's threat model, design principles, and performance in web analytics scenarios. Gain insights into how Zeph addresses the growing need for native privacy controls in data processing, protecting against potential breaches and unauthorized access.
