Re-Evaluating Internet Users’ Information Privacy Concerns: The Case in Japan

To expand the understanding of privacy concerns in the digital sphere, this paper makes use of the Internet Users’ Information Privacy Concerns (IUIPC) model by Malhotra et al. (2004). The lack of empirical studies conducted in East-Asian societies makes it difficult, if not impossible, to shed light on multi-cultural differences in information privacy concerns of internet users. Therefore, we collected data of more than 9,000 Japanese respondents to conduct a conceptual replication of the IUIPC model. For our research goal, we re-assess the validity and reliability of the IUIPC model for Japan and compare the results with internet users\u27 privacy concerns in the USA. Our results indicate that the second-order IUIPC construct, measured reflectively through the constructs awareness, collection, and control, is reliable and valid. Furthermore, three out of the five structural paths of the IUIPC model were confirmed for our Japanese sample. In contrast to the original study, the impact of IUIPC on trusting beliefs, as well as that of trusting beliefs on risk beliefs was negligible. Statistically significant differences in the IUIPC could only be found for the covariate gender

Cybersecurity of Digital Service Chains

This open access book presents the main scientific results from the H2020 GUARD project. The GUARD project aims at filling the current technological gap between software management paradigms and cybersecurity models, the latter still lacking orchestration and agility to effectively address the dynamicity of the former. This book provides a comprehensive review of the main concepts, architectures, algorithms, and non-technical aspects developed during three years of investigation; the description of the Smart Mobility use case developed at the end of the project gives a practical example of how the GUARD platform and related technologies can be deployed in practical scenarios. We expect the book to be interesting for the broad group of researchers, engineers, and professionals daily experiencing the inadequacy of outdated cybersecurity models for modern computing environments and cyber-physical systems

JonDonym users’ information privacy concerns

Privacy concerns as well as trust and risk beliefs are important factors that can influence users’ decision to use a service. One popular model that integrates these factors is relating the Internet Users Information Privacy Concerns (IUIPC) construct to trust and risk beliefs. However, studies haven’t yet applied it to a privacy enhancing technology (PET) such as an anonymization service. Therefore, we conducted a survey among 416 users of the anonymization service JonDonym [1] and collected 141 complete questionnaires. We rely on the IUIPC construct and the related trust-risk model and show that it needs to be adapted for the case of PETs. In addition, we extend the original causal model by including trust beliefs in the anonymization service provider and show that they have a significant effect on the actual use behavior of the PET
