Method and arrangement for providing an audit of a replica database

摘要

The invention is in the area of distributed system and database security. The invention relates to a method and an arrangement for increasing the level of trust between a master and a replica database by allowing the master database to perform an "unpredictable" audit of the replica database whenever deemed appropriate by the master database. The master database may for example define and generate an audit application and send it to at least one replica database using push synchronization and force the replica database to perform the audit application. The master database may also prepare expected results of the audit of the replica database and store them for later verification. After auditing the replica database may synchronize the results of the audit back to the master database for verification. The information flow between the master and replica databases is advantageously encrypted in a secure manner.
