Recently the databases are not in central location they are mostly distributed even geographically. Protecting the privacy over massive data that were store in different sites or in distributed systems are very important these days, because it will provoke serious consequences if the sensitive data get released without considering mechanism to protect this sensitive information. To overcome on the present issue the improvement can be done by separating patients identity from their medical data. The delicate data which needs to be uploaded to the system with the confidentiality constraints include major procedure namely data hiding. Privacy preserving distributed analysis of community health research data can be achieved by combining cryptography, suitable algorithms, constrain specification and enforcement.
