Mining Multiple Private Databases using a Privacy Preserving kNN Classier
Data mining technologies are popular for identifying interesting patterns and trends in large amounts of data. With the advent of high speed networks and easily available storage, many organizations are able to collect large amounts of data. On one hand, these organizations would like to mine their data to understand and discover interesting patterns; on the other hand, many legal and commercial reasons may prevent the organizations from sharing their data. In such situations, privacy preserving data mining tools become critical - they allow data from many organizations to be mined securely and with a minimum of information disclosure.
