Employ Privacy-Preserving Data Sharing
Privacy-preserving mechanisms should establish accessibility or electronic exchange of health data. Several methods exist for an HSNS to ensure data-sharing privacy. First, it can provide built-in mechanisms that afford users fine-grained control over how their personal information is shared. In addition to covering personally identifiable information, the mechanisms can let users set privacy policies for information about their medical conditions and other sensitive information. To reduce the burden on users, the site can provide intuitive user interfaces for changing privacy preferences. Second, the information exposed must be made anonymous via sophisticated anonymization techniques such as eliminating personal identifiers,15 cluster-based and graph modification approaches,3 and network data anonymization.4,5
