Data sharing is a process to make data from various sources available for specific purposes. The application of data sharing on mobile platforms is still hampered due to privacy issues. This is because data on the mobile platform is private and confidential. The solution to this problem is to use data sharing methods that maintain privacy. This final project creates a system that has the ability to do data sharing that maintains privacy. <br /> <br /> <br /> <br /> <br /> <br /> <br /> Data sharing participants have different database schemes between one another. One of the main privacy issues that need to be resolved is the need for methods to communicate in the form of queries between participants without divulging participant database schema information. Therefore, a method is needed to match the scheme without divulging participant schema information. <br /> <br /> <br /> <br /> <br /> <br /> <br /> Another privacy problem is that it requires a query execution method that maintains privacy. This method must be able to limit access to the results of query execution, so that only those who have access can get the results. <br /> <br /> <br /> <br /> <br /> <br /> <br /> In this final project, a system for data sharing is implemented that maintains privacy. Schema matching that maintains privacy is done by using a reference scheme. Query execution that maintains privacy is done by using privacy view and privacy policy for access control, not fully trusted third-party to combine query execution results, and encryption to ensure that no other party gets information from query execution. <br /> <br /> <br /> <br /> <br /> <br /> <br /> The test results show that all functional and non-functional needs have been met. The results of this test also show that the solution built successfully performs data sharing that maintains privacy well. <br />
