Privacy-First Edge AI: Why On-Device Processing Matters in Modern Health Apps
By HeySamay Security & Privacy Team
"Analyzing the systemic vulnerabilities of centralized cloud health data and explaining how local edge ML models protect sensitive biometric and dietary information."
Protecting Personal Biometrics at the Edge
Centralized cloud databases present ongoing risks of data breaches and third-party tracking. HeySamay prioritizes Data Localization through Edge Computation:
• Local Neural Inference: Meal photo segmentation, macronutrient estimation, and client-side document processing execute on device hardware.
• Zero Server Logs: User camera snapshots, health logs, and document binaries are processed locally and never retained on unauthorized servers.
