Abstract: Privacy auditing by storing a dataset comprising first data and second data for at least one User Equipment; storing ground truth labels for the first data and the second data; sending information based on the dataset to a network function; receiving, from the network function, information for determining a first value of a loss function; receiving, from the network function, information for determining a second value of the loss function; determining a difference between the first value of the loss function and the second value of the loss function; comparing the difference to a threshold to determine whether a Differential Privacy mechanism was applied to the first data before the network function trained the machine learning model based on the first data.

Abstract: A system comprising: at least one training unit for one or more data owners collaborating to the system for storing private data and at least one encrypted model, said training unit being implemented as a trusted execution environment; at least one aggregator unit for each model owner collaborating to the system for storing and executing code of a training algorithm, said aggregator unit being implemented as a trusted execution environment; at least one administration unit for controlling communication and synchronization between the at least one training unit and the at least one aggregator unit, said administration unit being implemented as a trusted execution environment; wherein the communication between the at least one training unit and the at least one aggregator unit is encrypted.
