Too much information!: user attitudes towards smartphone sharing

Abstract

Modern smartphones carry a huge amount of sensitive data. This includes personal information, business information or account information of various online services. In a situation where sharing the device with another person is unavoidable, this data might be in danger. In this paper, we present insights into up-to-date mobile device sharing behavior. We analyzed which data people are concerned of, which data people are willing to share and with whom people would share their device. Our results are based on the findings of a focus group and a user study. Based on those, we derived design implications, which can guide or help with the development of privacy-respectful sharing concepts for smartphones.
