Device and method for increasing the security of a database
The security of a database is substantially increased by partitioning raw data, irreversibly encrypting the partitioned raw data, reversibly encrypting the raw data, and then storing pairs of irreversibly encrypted data and reversibly encrypted data. In response to a search query, the query is partitioned and irreversibly encrypted, and the irreversibly encrypted query is used to search the stored irreversibly encrypted data. When a match is found, the reversibly encrypted data paired with the stored irreversibly encrypted data that matches the irreversibly encrypted query is output in response to the search query.
