A Survey on Interdependent Privacy <s> Communication Privacy Management Theory <s> For families, managing private information is challenging. Family members reveal too much, they allow more privacy access to outsiders than others desire, parents attempt to negotiate Internet disclosures with their teens, and family health issues often change the way private information is defined altogether. The complexities of privacy regulation call for a systematic way to grasp how privacy management operates in families. This article presents the evidenced-based theory of communication privacy management (CPM) and corresponding research on family privacy regulation that provides a road map to understand the multifaceted nature of managing private information (Petronio, 2002). The article discusses contributions of CPM to conceptualizing privacy in meaningful ways, along with current research trends and future directions for CPM research and theorizing. <s> BIB001 </s> A Survey on Interdependent Privacy <s> Communication Privacy Management Theory <s> In online social networks, because one's private information can be co-owned and disclosed by peers, a new type of privacy concern, i.e., information privacy concern about peer disclosure (IPCPD), looms large. Should a member of an online social network be offered decision control to veto ex-ante the disclosure of his/her information by peers? There has been no theoretical research on the effectiveness of decisional control to alleviate such a privacy concern. Drawing on the communication privacy management perspective and the impression management theory, this study proposes a three-way interaction effect among three important antecedents of IPCPD: 1) decisional control; 2) image discrepancy (i.e., the degree to which the disclosed information portrays an unfavorable image of the disclosed person); and 3) social network overlap between the disclosed person and the discloser. Our experimental study reveals significant findings. When image discrepancy is low, decisional control is helpful only when the social network overlap between the disclosed one and the discloser is low. When image discrepancy is high, decisional control is helpful only when the social network overlap between the disclosed one and the discloser is high. This study contributes to a theory of privacy concern about peer disclosure in the context of online social networks. <s> BIB002 </s> A Survey on Interdependent Privacy <s> Communication Privacy Management Theory <s> With the rise of social networking sites (SNSs), individuals not only disclose personal information but also share private information concerning others online. While shared information is co-constructed by self and others, personal and collective privacy boundaries become blurred. Thus there is an increasing concern over information privacy beyond the individual perspective. However, limited research has empirically examined if individuals are concerned about privacy loss not only of their own but their social ties’; nor is there an established instrument for measuring the collective aspect of individuals’ privacy concerns. In order to address this gap in existing literature, we propose a conceptual framework of individuals’ collective privacy concerns in the context of SNSs. Drawing on the Communication Privacy Management (CPM) theory (Petronio, 2002), we suggest three dimensions of collective privacy concerns, namely, collective information access, control and diffusion. This is followed by the development and empirical validation of a preliminary scale of SNS collective privacy concerns (SNSCPC). Structural model analyses confirm the three-dimensional conceptualization of SNSCPC and reveal antecedents of SNS users’ concerns over violations of the collective privacy boundaries. This paper serves as a starting point for theorizing privacy as a collective notion and for understanding online information disclosure as a result of social interaction and group influence. <s> BIB003
Communication privacy management (CPM) theory, developed by Petronio, models how individuals share and manage private information when communicating with each other  ]. This theory has been successfully applied to analyze information sharing in all sorts of relationships, including between relatives (e.g., parent-child), friends, and co-workers (e.g., superiorsubordinate), be it offline (i.e., in the real world) or online (i.e., on the Internet). This theory builds on the metaphor of boundaries that separate individuals' private (i.e., private boundary) and public spheres. CPM theory is based on five key principles: ownership, control, rules, co-ownership and boundary turbulence BIB001 ]. Private information belongs to a particular individual defined as the owner. When private information is shared, a collective boundary is created between the individual who discloses the information and the one who receives it, the receiver (e.g., a tagged individual). A receiver is then considered as a co-owner of the shared information and a collective boundary protects the private information by defining privacy rules to coordinate all the private boundaries of co-owners. These rules control who has access to the information and determine the possibility of extending the involved co-owners (linkage rules), the degree of access to the information (permeability rules), and the implication of co-owners in the decision making of rules (ownership rules). The last of the five principles, boundary turbulences, occurs when a co-owner discloses, by mistake or intentionally, the information outside the initially defined boundary. Application to interdependent privacy. Communication privacy management theory helps model how individuals collaboratively decide on the audience of some content they co-own on OSNs, a typical interdependent privacy situation/multi-party privacy conflict. In such cases, permeability rules capture fine-grained access control (e.g., show only part of the faces in a picture), and boundary turbulences capture the increase of the audience of a content when a user re-shares some content, thus making it visible and accessible to their own contacts on the OSN. It has been applied in several works BIB002  BIB003 ] (see Section 5.1.2).
