However, this approach has shortcomings in terms of confidentiality and fairness. Model updates can lead to membership inference attacks, while unbalanced local datasets can introduce classification biases, particularly for minority groups.<\/p>\n\n\n\n<p>The TRUSTINCloudS project has developed a new inference attack exploiting fairness metrics when training the global model. To counter this threat, they propose a fairness-sensitive encrypted domain aggregation algorithm that is differentially private by design. This uses the approximate loss of precision of the homomorphic multi-key CKKS threshold encryption scheme.<\/p>\n\n\n\n<p>The results, presented at PETS 2025, demonstrate the effectiveness of this approach in terms of fairness and confidentiality, validated by experiments on three real data sets.<\/p>\n\n\n\n<p class=\"has-text-align-left\"><strong><em>To find out more, read the full paper <a href=\"https:\/\/hal.science\/hal-04782394v1\" data-type=\"URL\" data-id=\"https:\/\/hal.science\/hal-04782394v1\">here<\/a>.<\/em><\/strong><\/p>","protected":false},"excerpt":{"rendered":"<p>TRUSTINCloudS at PETS 2025: Innovations in Cybersecurity and Federated Learning From July 14 to 19, 2025, Washington DC will host the 25th edition of the Privacy Enhancing Technologies Symposium (PETS).
