Auditing of curation information

摘要

An approach that tracks curation history of sensitive information is described. In one embodiment, there is a database that contains a plurality of sensitive information. The database comprises a plurality of base tables and backlog tables for each of the base tables. A curation audit query generator is configured to receive a curation audit expression that specifies sensitive information to be audited and generates a curation audit query from the curation audit expression to run against the database. The curation audit expression contains syntax clauses that specify a time period for the audit, stipulate a specific base table in the database as source of the audit and examine whom is responsible for making changes to the specified sensitive information.
