Abstract
A computing device may determine that a policy event to initiate data destruction for a first set of data has been triggered. The first set of data may be located on a first file. The computing device may delete, in response to the determining, a first security key used for decrypting the first set of data. The computing device may delete, in response to the determining, one or more transaction log entries associated with the first set of data. The one or more transaction log entries may include a copy of the first set of data. The one or more transaction log entries may be a part of a transaction log. The transaction log may be a second file that stores a history of each data change within the database.
