联邦学习(FL,federated learning)是一种新兴的分布式机器学习技术,利用分散在各个机构的数据,通过传输中间结果(如模型参数、参数梯度、嵌入信息等)实现机器学习模型的联合构建。联邦学习中机构的训练数据不允许离开本地,因此降低了数据泄露的风险。根据机构之间数据分布的差异,FL 通常分为横向联邦学习(HFL,horizontal FL)、纵向联邦学习(VFL,vertical FL),以及联邦迁移学习(TFL, transfer FL)。其中,VFL适用于机构具有相同样本空间但不同特征空间的场景,广泛应用于医疗诊断、金融评估和教育服务等领域。尽管 VFL 在现实应用中有出色的表现,但其本身仍然面临诸多隐私和安全问题,尚缺少对VFL方法与安全性展开全面综述的工作。为了构建高效且安全的VFL系统,从VFL方法及其隐私和安全两个方面展开,首先从边缘模型、通信机制、对齐机制以及标签处理机制4个角度对现有的VFL方法进行详细总结和归纳;其次介绍并分析了 VFL 面临的隐私和安全风险;进一步对其防御方法进行介绍和总结;此外,介绍了适用于VFL的常见数据集及平台框架。结合VFL面临的安全性挑战给出了VFL的未来研究方向,旨在为构建高效、鲁棒和安全的VFL的理论研究提供参考。
Federated learning (FL) is a distributed machine learning technology that enables joint construction of machine learning models by transmitting intermediate results (e.g.
model parameters
parameter gradients
embedding representation
etc.) applied to data distributed across various institutions.FL reduces the risk of privacy leakage
since raw data is not allowed to leave the institution.According to the difference in data distribution between institutions
FL is usually divided into horizontal federated learning (HFL)
vertical federated learning (VFL)
and federal transfer learning (TFL).VFL is suitable for scenarios where institutions have the same sample space but different feature spaces and is widely used in fields such as medical diagnosis
financial and security of VFL.Although VFL performs well in real-world applications
it still faces many privacy and security challenges.To the best of our knowledge
no comprehensive survey has been conducted on privacy and security methods.The existing VFL was analyzed from four perspectives: the basic framework
communication mechanism
alignment mechanism
and label processing mechanism.Then the privacy and security risks faced by VFL and the related defense methods were introduced and analyzed.Additionally
the common data sets and indicators suitable for VFL and platform framework were presented.Considering the existing challenges and problems
the future direction and development trend of VFL were outlined
to provide a reference for the theoretical research of building an efficient
robust and safe VFL.
