AI总结:

针对现有本地差分隐私方法无法保护电器级智能电表流数据隐私的问题,提出带滑动窗口随机响应的LDP-SmartEnergy方法,在隐私保护与数据效用间取得平衡且效率更优。

摘要:

能量分解技术利用智能电表数据推断电器能耗,可为消费者和能源公司的能源管理提供宝贵洞察,但这类技术也带来隐私风险,例如可能被用于行为画像。本地差分隐私(LDP)方法在解决隐私问题时具备强隐私保障与高效率的特点,但现有LDP方法聚焦于保护聚合能耗数据,而非单个电器的数据。此外,这些方法未考虑智能电表数据属于流数据的事实,其处理方法应当考虑时间窗口。本文提出一种新颖的LDP方法(名为LDP-SmartEnergy),该方法采用带滑动窗口的随机响应技术,支持随时间共享电器级能耗数据,同时不会泄露单个用户的电器使用模式。我们的评估显示,与基线方法相比,LDP-SmartEnergy运行效率更高,结果还表明我们的方案在保护隐私和维持数据有效分析的效用之间实现了平衡。

英文摘要:

Energy disaggregation techniques, which use smart meter data to infer appliance energy usage, can provide consumers and energy companies valuable insights into energy management. However, these techniques also present privacy risks, such as the potential for behavioral profiling. Local differential privacy (LDP) methods provide strong privacy guarantees with high efficiency in addressing privacy concerns. However, existing LDP methods focus on protecting aggregated energy consumption data rather than individual appliances. Furthermore, these methods do not consider the fact that smart meter data are a form of streaming data, and its processing methods should account for time windows. In this paper, we propose a novel LDP approach (named LDP-SmartEnergy) that utilizes randomized response techniques with sliding windows to facilitate the sharing of appliance-level energy consumption data over time while not revealing individual users' appliance usage patterns. Our evaluations show that LDP-SmartEnergy runs efficiently compared to baseline methods. The results also demonstrate that our solution strikes a balance between protecting privacy and maintaining the utility of data for effective analysis.
