Contextual integrity
Contextual integrity is a theory of privacy developed by Helen Nissenbaum and presented in her book Privacy In Context: Technology, Policy, and the Integrity of Social Life. It comprises four essential descriptive claims:
- Privacy has to do with appropriate flows of information.
- Appropriate information flows are those that conform with contextual information norms.
- Contextual informational norms involve five independent parameters: data subject, sender, recipient, information type, and transmission principle.
- Conceptions of privacy are based on ethical concerns that evolve over time.
The theory of contextual integrity seeks to define, clarify, and organize conceptions of privacy in a manner that is relevant even in evolving information environments. When applied, contextual integrity serves to illuminate a range of concerns to consider when designing systems, making decisions, or establishing policy that implicate flows of information and information privacy. It provides a framework for distinguishing between appropriate and inappropriate information flows, and thus for making ethical decisions and avoiding privacy violations as the development of new technologies enables novel flows of information.
