Private analytics via zero-trust aggregation
Google Research has developed a new cryptographic protocol for private analytics, combining secure aggregation with Trusted Execution Environments (TEEs). This zero-trust approach allows on-device AI systems to collect aggregated insights about their performance and user behavior without compromising individual user privacy. The system aims to address challenges in understanding model drift, biases, and real-world error rates by providing anonymized, collective trends. AI
