Social software has become one of the most prominent means for communication.
Context is essential for managing privacy and guiding communication.
However, in social software, context can be ambiguous due to the overload of data and the mix of various audiences, resulting in privacy issues.
To overcome context issues, we analyse the role of context
in communication and privacy
management, and propose CPS^2, a conceptual framework of contextual privacy management.
CPS^2 identifies the interpretation of data as the ingredient in
contextual privacy management that once preserved within
any disclosure context, contextual privacy can be preserved.
We present how CPS^2 can be technically realised,
and how it addresses context issues and offers fine-granular context control.
