Abstract
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.
Highlights
Privacy concerns have been discussed since the very beginning of computer sharing [2]
The Internet Users Information Privacy Concerns (IUIPC) construct has been used in various contexts, e.g. Internet of Things [7], internet transactions [8] and Mobile Apps [9], but to the best of our knowledge the IUIPC construct has never been applied to a privacy enhancing technology (PET) such as anonymization services
We investigate the privacy, trust and risk beliefs associated with PETs for the case of the anonymity service JonDonym [1]
Summary
Privacy concerns have been discussed since the very beginning of computer sharing [2]. One popular model for measuring and explaining privacy concerns of online users is the Internet Users Information Privacy Concerns (IUIPC) construct by Malhotra et al [6]. Their research involves a theoretical framework and an instrument for operationalizing privacy concerns, as well as a causal model for this construct including trust and risk beliefs about the online companies’ data handling of personal information. For anonymization services the primary purpose is to help users to protect their privacy. It is necessary to distinguish between trust and risk beliefs with respect to technologies which aim to protect personal (PETs) and regular internet services. 2 briefly introduces the JonDonym anonymization service and lists related work on PETs. In section 3, we present the research hypotheses and describe the questionnaire and the data collection process.
