| Summary: | 碩士 === 國立中山大學 === 資訊管理學系研究所 === 102 === Because of the expanding of smartphones, the applications on smartphones, Apps, are widely discussed. In Android platform, Apps have to acquire permissions in order to provide various functions for users. However, Apps might request more permissions than they need. Users have to grant permissions requested by Apps before downloading Apps. The purpose of this study is understanding the impacts of permissions on users'' intention to download mobile Apps. We proposed the concept of &;quot;permission-function fit (PFF)&;quot;, and included perceived privacy risk and social exchange theory into TAM to explore the research purpose.
The results of this study are: (1) users'' attitude toward the App positively influences their download intention. (2) Users'' perceived usefulness and the ranking of the App positively influence users'' attitude toward the App; perceived privacy risk negatively affect users'' attitude; when App requests more permissions than it needs, users have negative attitude toward it. Perceived usefulness has the strongest effect on attitude. (3)The privacy level of permissions positively affects users'' perception of privacy risk; when Apps request more permissions than they need, users perceive higher privacy risk.
