Privacy fatigue in the internet of things(IoT) environment∗

The purpose of this study is to analyze the phenomenon of privacy fatigue in an Internet-of-Things environment. As the paradigm shifts from towards IoT, users’ perception of personal information is also changing. Users’ perception of personal information and people’s actions to protect personal information have a great impact on security. Because the theory of protection motivation is a representative theory to explain the change of users’ protection behavior against the threat, we conducted a structured in-depth interview based on the motivation theory. As a result of the interview, various results came out which were not found in previous studies such as that the level of security knowledge of IoT users, the usage environment and purpose of IoT devices affect privacy fatigue. These results will be of benefit to IoT device designers and privacy researchers and can be the basis for a variety of follow-up studies.
