Abstract
Techniques for priority-based masking policy selection in a database environment are described. Masking policies are defined and attached to columns of relational data for particular users or roles. The attachment of a masking policy to a column includes a user-specified priority value. When multiple policies could apply to a particular query, the conflict can be easily resolved and understood by use of the priority values, for example, by selecting a candidate policy having a highest priority value.
