While it is important for data owners to publish their data to a third party for providing data mining services, the privacy of the data itself needs to be maintained. Therefore, several perturbation methods have been introduced considering potential applications.

Such distance-preservation is vital for providing a high accuracy that reflexes a minimal data loss when performing data clustering.
