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 is provided by appropriate flows of information.
• Appropriate information flows are those that conform with contextual information norms
• Contextual informational norms refer to five independent parameters: data subject, sender, recipient, information type, and transmission principle
• Conceptions of privacy are based on ethical concerns that evolve over time
