Abstract

Methods, systems, and computer-readable storage media for privacy preserving metering is described herein. A resource threshold value associated with anonymizing meter data for resources metered at a first destination is received. Based on a noise scale value and the resource threshold value, an individual inference value of the first destination is computed. The individual inference value defines a probability of distinguishing the first destination as a contributor to a query result based on anonymized meter data of the first destination and other destinations according to the noise scale value. The noise scale value is defined for a processing application. Based on evaluating the individual inference value, it is determined to provide anonymized meter data for metered resources at the first destination. An activation of a communication channel for providing the anonymized meter data for metered resources is triggered. The communication channel is between the first destination and the processing application.
