Attribute Disclosure Risk in Smart Meter Data

This paper studies attribute disclosure risk in aggregated smart meter data. Smart meter data is commonly aggregated to preserve the privacy of individual contributions. The published data shows aggregated consumption, preventing the revelation of individual consumption patterns. There is, however, a potential risk associated to aggregated data. We analyze some datasets of smart meter data consumption to show the potential risk of attribute disclosure. We observe that, even if data is aggregated with the most favorable aggregation approach, it presents this attribute disclosure risk.
