  • Patent number: 10540508
    Abstract: One embodiment of the present invention provides a system that secures a database configuration from undesired modifications. This system allows a security officer to issue a configuration-locking command, which activates a lock for the configuration of a database object. When a configuration lock is activated for a database object, the system prevents a user (e.g., a database administrator) from modifying the configuration of the database object, without restricting the user from accessing the database object itself. The security officer is a trusted user that is responsible for maintaining the stability of the database configuration, such that a configuration lock activated by the security officer preserves the database configuration by overriding the privileges assigned to a database administrator.

  • Patent number: 8239396
    Abstract: A machine-implemented method and machine-readable media for transforming sensitive data in a database is provided. Sensitive data in the database are transformed based on a query context of a query. The query may also be transformed. The transformed query may be applied against the transformed sensitive data to construct a query result. The query result with the transformed sensitive data represents a lenticular view. The lenticular view represents a modified form of the sensitive data that an end-user is allowed access to.
