Abstract:
Users reveal privacy sensitive information when they post on social media, which can have negative consequences. To help these users make informed decisions, different tools have been developed that detect privacy sensitive information (PSI) and provide alerts. However, how users would perceive this type of tool has not yet been evaluated. In this position paper, we take the first steps to address this gap, by exploring user intention, perceived usefulness and attitude towards a PSI detection tool. We designed an experiment and showed participants examples of the PSI detection tool alerts, and quantitatively and qualitatively evaluated their response. The results showed that participants perceived the PSI detection tool as useful, had positive interest, and a low level of concern about it, although they had a neutral level of intention of using the tool. The participants’ open-ended responses revealed that they considered the PSI detection tool useful, but mostly for other people and
not for themselves. In addition, they were concerned about the privacy risks of using the tool and about its effectiveness. The findings reveal the challenges that PSI detection tools have to overcome to gain acceptance among users that would benefit from this type of privacy protection.
