Differential Privacy Systems

Google's commitment to online safety and user privacy has evolved through the expansion of Differential Privacy systems. Early efforts focused on foundational research and internal applications of differential privacy techniques to protect user data while enabling aggregate analysis. Subsequent developments have seen the open-sourcing of libraries and tools, making differential privacy more accessible to developers and researchers. This evolution aims to create a safer online ecosystem by providing the largest application of differential privacy in the world spanning close to three billion devices, improving products like Google Home, Google Search on Android, and Messages. New releases include PipelineDP4j for JVM, DP-Auditorium for auditing differentially private algorithms, and advancements in Google Trends insights for low-volume locales.
