PrivESD: A Privacy-Preserving Cloud-Edge Collaborative Logistic Regression Model Over Encrypted Streaming Data

PrivESD is a new system that allows machine learning classification (logistic regression, a technique for categorizing data) to work on encrypted streaming data (continuously flowing information that's been scrambled for privacy) while stored in the cloud. The system splits the computational work between cloud servers and edge devices (computers closer to where data originates) to reduce processing burden and privacy risks, and uses special encryption methods that still allow the system to compare values without revealing the actual data.
