Very little research has examined how engaging in tagging with one’s friends is related to an individual’s privacy concerns or Facebook usage. We only found one study that focused specifically on the collaborative privacy management of photos by content owners and co-owners. Squicciarini, Xu, and Zhang (2011) developed a Facebook app that facilitated the joint management of co-owned photos. They had users login to a fake Facebook account to
explore the features of the app and found that ease of use, usefulness, and likability of the app were significant factors in SNS users’ intent to use the app in the future; however, privacy concern was not significantly related to any of the other factors in their model (Squicciarini et al., 2011). Instead of developing an app prototype for managing co-owned information, our study focuses on how SNS users’ privacy concerns are related to their current tagging engagement with friends and SNS usage. We believe that our approach will help us better understand how privacy concerns are related to confidant disclosures of co-owned information.
