English(EN) Enhanced Detective: A Dual-Stage Proactive Defense Against Internal Poisoning Attacks in Financial Fraud Detection Using Federated Learning

新型防御增强联邦学习以抵御金融欺诈检测攻击

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了一种名为增强型侦探（Enhanced Detective）的新型防御机制，以应对联邦学习在金融欺诈检测中面临的内部投毒攻击。该双阶段策略结合了中位数绝对偏差（MAD）与基于距离的更新过滤和FedMedian聚合。实验表明，即使有40%的恶意客户端参与训练过程，增强型侦探也能达到0.796的AUPRC和0.847的召回率。 AI

影响 增强了在敏感金融应用中使用的联邦学习模型的安全性。
