A method for securing content in a database includes identifying a challenge column associated with a database column referenced in an update query. A challenge value for the challenge column may be received and resolved for a match with a corresponding value stored in the challenge column. In case of a match, the update query may be certified for execution on the database, otherwise, the update query may be prevented from executing. Challenge columns may be determined by an analysis of the database on the basis of discriminating power, description complexity, and/or diversity. |
