Abstract:
The skyline of a set of d-dimensional points contains the points that are not dominated by any other point on these d-dimensions. Querying skyline points and its computation has recently received considerable attention in the database community. Skyline points are important in database systems. They are useful for multi-criteria decision making systems and data mining systems. There are several algorithms that query data by Skyline computation. Also, there are several algorithms that query requested data from encrypted data. In my proposed system, the Skyline computation is proposed in a secure way. I combine encryption process and skyline computation in a single system. For encryption, order preserving encryption, OPES is used, which helps in the performance. The security of the system is strengthened by the schema hiding procedure in the proposed system. By this system, the skyline computation can be outsourced in a secure way. The client-server architecture is used for outsourcing. In summary, this system proposes Skyline computation in a secure way.
