摘要

联网和自动驾驶汽车(cav)通过识别和减轻危险驾驶行为,为提高道路安全提供了一个变革性的机会。然而,目前在自动驾驶汽车中评估这些行为的方法忽略了隐私问题,因为所有终端设备都需要将原始数据直接上传到中央服务器进行分析。这些数据通常包括敏感的个人信息,增加了潜在的隐私泄露风险。为了应对这一挑战,我们引入了联邦学习(FL),一种保护隐私的机器学习技术,并提出了一个用于危险驾驶行为评估的联邦差分私有风险评估网络(FedDPRAN)。特别是,我们首先使用风险评估网络(RAN)提取每个客户的驾驶行为特征,遵循最小化驾驶行为特征差异同时最大化驾驶员隐私特征差异的对抗原则。然后,提出了一种利用本地RAN模型的FL解决方案,在不共享实际数据的情况下与云服务器协作和交换学习参数。为了增强FL框架中的隐私性,我们为每个客户端集成了差分隐私(DP)解决方案。基于两个真实数据集进行了综合实验。结果表明,我们评估自动驾驶汽车危险驾驶行为的方法在保护隐私的同时优于最先进的方案。

Federated differentially private framework for risky driving behaviour assessment
Connected and Automated Vehicles (CAVs) offer a transformative opportunity to enhance road safety by identifying and mitigating risky driving behaviours. However, current methods for assessing these behaviours in CAVs overlook privacy concerns, as all terminal devices are required to upload original data directly to a central server for analysis. This data often includes sensitive personal information, raising the risk of potential privacy breaches. To address this challenge, we introduce Federated Learning (FL), a privacy-preserving machine learning technique, and propose a Federated Differentially Private based Risk Assessment Network (FedDPRAN) for risky driving behaviour assessment. In particular, we begin by extracting driving behaviour characteristics for each client using the Risk Assessment Network (RAN), following the adversarial principle of minimizing the difference in driving behaviour features while maximizing the difference in privacy features of the driver. Then, a new FL solution that utilizes the local RAN model is proposed to collaborate and exchange learned parameters with a cloud server without sharing actual data. To enhance privacy in the FL framework, we integrate a Differential Privacy (DP) solution for each client. Comprehensive experiments are conducted based on two real-world datasets. The results demonstrate that our approach to assessing risky driving behaviour in CAVs protects privacy while being superior to state-of-the-art schemes.
