ABSTRACT
The increasing use of social networking sites (SNS) in health care has resulted in a growing number of individuals posting personal health information online. These sites may disclose users' health information to many different individuals and organizations and mine it for a variety of commercial and research purposes, yet the revelation of personal health information to unauthorized individuals or entities brings a concomitant concern of greater risk for loss of privacy among users. Many users join multiple social networks for different purposes and enter personal and other specific information covering social, professional, and health domains into other websites. Integration of multiple online and real social networks makes the users vulnerable to unintentional and intentional security threats and misuse. This paper analyzes the privacy and security characteristics of leading health-related SNS. It presents a threat model and identifies the most important threats to users and SNS providers. Building on threat analysis and modeling, this paper presents a privacy preservation model that incorporates individual self-protection and privacy-by-design approaches and uses the model to develop principles and countermeasures to protect user privacy. This study paves the way for analysis and design of privacy-preserving mechanisms on health-related SNS.

Mentions: The SNS provider and its affiliates may use health information for many purposes. It may also release health information to various third parties and apps or enable exchange of information with other social networks. We may include these additional actors into a usage and sharing network that involves the SNS provider and its affiliates, a set of third parties that collect data from the site, a set of apps that users may invoke within the site, a set of other SNS or websites, and government agencies, including law enforcement and public health. An information flow diagram for a health-related SNS is shown in Figure 1.
