Abstract
A database management system provided in a trusted execution environment controls the visibility of a requested statistic for a database table column based on the source of the request. The visibility control is based on a visibility level of the database table column to the source of the request. The visibility of the provided statistic can further be based on a security level of the database table column even if the source of the request is not a permitted viewer. The statistic can include frequency or histogram data for the database table column.
