The incentive model is very efficient to protecting the sensitive data in privacy preserving data sharing system because it provides the secrecy against not only semihonest adversary model and also the malicious model. Although data privacy and security go hand in hand, they are two different concepts. Considering privacy requirements by including all the perspectives of data helps us to come up with system requirements for those privacy issues which could not be addressed till now, for example, unwanted disclosure by other users.
