【Abstract】Connected and Autonomous Vehicles (CAVs) are introduced to improve individuals' quality of life by offering a wide range of services. They collect a huge amount of data and exchange them with each other and the infrastructure. The collected data usually includes sensitive information about the users and the surrounding environment. Therefore, data security and privacy are among the main challenges in this industry. Blockchain, an emerging distributed ledger, has been considered by the research community as a potential solution for enhancing data security, integrity, and transparency in Intelligent Transportation Systems (ITS). However, despite the emphasis of governments on the transparency of personal data protection practices, CAV stakeholders have not been successful in communicating appropriate information with the end users regarding the procedure of collecting, storing, and processing their personal data, as well as the data ownership. This article provides a vision of the opportunities and challenges of adopting blockchain in ITS from the data transparency and privacy perspective. The main aim is to answer the following questions: (1) Considering the amount of personal data collected by the CAVs, such as location, how would the integration of blockchain technology affect transparency, fairness, and lawfulness of personal data processing concerning the data subjects (as this is one of the main principles in the existing data protection regulations)? (2) How can the trade-off between transparency and privacy be addressed in blockchain-based ITS use cases?

【标题】区块链与联网和自动驾驶汽车的整合：愿景与挑战
【摘要】互联和自动驾驶汽车（CAVs）的推出是为了通过提供广泛的服务来改善个人的生活质量。它们收集大量的数据，并与对方和基础设施交换。收集的数据通常包括关于用户和周围环境的敏感信息。因此，数据安全和隐私是这个行业的主要挑战之一。区块链，一个新兴的分布式账本，已经被研究界认为是提高智能交通系统（ITS）中数据安全性、完整性和透明度的潜在解决方案。然而，尽管政府强调个人数据保护做法的透明度，但CAV的利益相关者并没有成功地与终端用户沟通有关收集、存储和处理其个人数据的程序以及数据所有权的适当信息。本文从数据透明度和隐私的角度对在ITS中采用区块链的机会和挑战进行了展望。主要目的是为了回答以下问题。(1) 考虑到CAVs收集的个人数据量，如位置，区块链技术的整合将如何影响有关数据主体的个人数据处理的透明度、公平性和合法性（因为这是现有数据保护法规的主要原则之一）？(2) 在基于区块链的ITS用例中，如何解决透明度和隐私之间的权衡问题？
