摘要:

医疗数据在数据隐私和安全问题方面通常非常敏感。联邦学习是机器学习技术的一种,已经开始用于提高医疗数据的隐私性和安全性。在联邦学习中,训练数据分布在多台机器上,学习过程以协作方式执行。针对深度学习(DL)模型的隐私攻击主要是为了获取敏感信息。因此,应该保护DL模型本身免受对抗攻击,特别是对于使用医疗数据的应用。针对该问题的解决方案之一是基于同态加密的模型保护以防止对手合作者。提出了一种基于同态加密的隐私保护医疗数据联邦学习算法。该算法使用安全的多方计算协议来保护深度学习模型免受攻击。在这项研究中,所提出的算法使用真实世界的医疗数据集进行评估的模型性能。

英文摘要:

Medical data is often highly sensitive in terms of data privacy and security concerns. Federated learning, one type of machine learning techniques, has been started to use for the improvement of the privacy and security of medical data. In the federated learning, the training data is distributed across multiple machines, and the learning process is performed in a collaborative manner. There are several privacy attacks on deep learning (DL) models to get the sensitive information by attackers. Therefore, the DL model itself should be protected from the adversarial attack, especially for applications using medical data. One of the solutions for this problem is homomorphic encryption-based model protection from the adversary collaborator. This paper proposes a privacy-preserving federated learning algorithm for medical data using homomorphic encryption. The proposed algorithm uses a secure multi-party computation protocol to protect the deep learning model from the adversaries. In this study, the proposed algorithm using a real-world medical dataset is evaluated in terms of the model performance.
