Privacy in inter-vehicular networks: Why simple pseudonym change is not enough

Abstract: Inter-vehicle communication (IVC) systems disclose rich location information about vehicles. State-of-the-art security architectures are aware of the problem and provide privacy enhancing mechanisms, notably pseudonymous authentication. However, the granularity and the amount of location information IVC protocols divulge, enable an adversary that eavesdrops all traffic throughout an area, to reconstruct long traces of the whereabouts of the majority of vehicles within the same area. Our analysis in this paper confirms the existence of this kind of threat. As a result, it is questionable if strong location privacy is achievable in IVC systems against a powerful adversary.

Examined Lives: Informational Privacy and the Subject as Object

Abstract: In the United States, proposals for informational privacy have proved enormously controversial. On a political level, such proposals threaten powerful data processing interests. On a theoretical level, data processors and other data privacy opponents argue that imposing restrictions on the collection, use, and exchange of personal data would ignore established understandings of property, limit individual freedom of choice, violate principles of rational information use, and infringe data processors' freedom of speech. In this article, Professor Julie Cohen explores these theoretical challenges to informational privacy protection. She concludes that categorical arguments from property, choice, truth, and speech lack weight, and mask fundamentally political choices about the allocation of power over information, cost, and opportunity. Each debate, although couched in a rhetoric of individual liberty, effectively reduces individuals to objects of choices and trades made by others. Professor Cohen argues, instead, that the debate about data privacy protection should be grounded in an appreciation of the conditions necessary for individuals to develop and exercise autonomy in fact, and that meaningful autonomy requires a degree of freedom from monitoring, scrutiny, and categorization by others. The article concludes by calling for the design of both legal and technological tools for strong data privacy protection.

Low-Latency Federated Learning and Blockchain for Edge Association in Digital Twin Empowered 6G Networks

Abstract: Emerging technologies, such as digital twins and 6th generation (6G) mobile networks, have accelerated the realization of edge intelligence in industrial Internet of Things (IIoT). The integration of digital twin and 6G bridges the physical system with digital space and enables robust instant wireless connectivity. With increasing concerns on data privacy, federated learning has been regarded as a promising solution for deploying distributed data processing and learning in wireless networks. However, unreliable communication channels, limited resources, and lack of trust among users hinder the effective application of federated learning in IIoT. In this article, we introduce the digital twin wireless networks (DTWN) by incorporating digital twins into wireless networks, to migrate real-time data processing and computation to the edge plane. Then, we propose a blockchain empowered federated learning framework running in the DTWN for collaborative computing, which improves the reliability and security of the system and enhances data privacy. Moreover, to balance the learning accuracy and time cost of the proposed scheme, we formulate an optimization problem for edge association by jointly considering digital twin association, training data batch size, and bandwidth allocation. We exploit multiagent reinforcement learning to find an optimal solution to the problem. Numerical results on real-world dataset show that the proposed scheme yields improved efficiency and reduced cost compared to benchmark learning methods.

Accountability as a Way Forward for Privacy Protection in the Cloud

Abstract: The issue of how to provide appropriate privacy protection for cloud computing is important, and as yet unresolved. In this paper we propose an approach in which procedural and technical solutions are co-designed to demonstrate accountability as a path forward to resolving jurisdictional privacy and security risks within the cloud.

Privacy and security: an ethical analysis

Abstract: During the past decade, Canadian information highway policy and e-commerce strategy underwent a tremendous amount of policy, academic, and national and international debate. There was, however, no substantive philosophical justification of privacy as a human right beyond its prima facie link with human dignity and autonomy. On what philosophical ground, however, ought legislation seek to instantiate physical privacy, privacy of personal information, freedom from surveillance, privacy of personal communications, and privacy of personal space into public policy? The philosophical meaning of privacy as a social value has also gone undeveloped in information policy documents. The government has called upon academics for \"open commtmication and dialogue\" on how best to protect personal information in the private sector, and how best to think about the ethical and policy implications of privacy, security, and new surveillance technologies. Fair infbrmation principles appropriate for database forms of surveillance np to last decade, are necessary but insufficient for deciding whether a given means of data collection is ethically acceptable (Marx, 1999). Bill C-6 attempts to strike the right balance between the business need to gather, store, and use personal information, and the consumer need to be informed about how that information will be used and protected. The cryptography policy framework for e-commerce seeks to balance the legitimate use and flow of digital data, with privacy and civil and hmnan rights concerns and law enforcement and national security interests. And yet, how may we best achieve ethical balance? What are the limits of legal rights for coping with radically new privacy and security challenges?
