Exposing others' information on online social networks (OSNs): Perceived shared risk, its determinants, and its influence on OSN privacy control use

People using online social networks (OSNs) exchange information through posts of multimedia content, which may contain others' information. Our study contributes to the privacy literature by examining individuals' perceptions of the risk their OSN activity poses to others' information. We introduce the concept “perceived shared risk,” which includes OSN users' perceived severity and susceptibility of exposing others' information. Results indicate culture, concerns regarding one's own information, and Facebook information disclosure self-efficacy influence both risk components. We also identify a correlation between perceived shared risk and the use of OSN privacy controls.
