Low-power and Computing-free Privacy Design for IoT Systems

This work is the first to leverage the tendency of hardware transistors to degrade under voltage drop as a source of noise for Local Differential Privacy (LDP). We propose SRAM_DP, a hardware-software co-design for achieving differential privacy on semi-structured data. Experiments on a custom SRAM design, using the WHO-released disease dataset, show that the method preserves individual privacy while retaining meaningful data distribution analysis.
