How Privacy Concerns and Trust and Risk Beliefs Influence Users’ Intentions to Use Privacy-Enhancing Technologies - The Case of Tor

Due to an increasing collection of personal data by internet companies and several data breaches, research related to privacy gained importance in the last years in the information systems domain. Privacy concerns can strongly influence users’ decision to use a service. The Internet Users Information Privacy Concerns (IUIPC) construct is one operationalization to measure the impact of privacy concerns on the use of technologies. However, when applied to a privacy enhancing technology (PET) such as an anonymization service the original rationales do not hold anymore. In particular, an inverted impact of trusting and risk beliefs on behavioral intentions can be expected. We show that the IUIPC model 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 itself. A survey among 124 users of the anonymization service Tor shows that they have a significant effect on the actual use behavior of the PET

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
