The dynamic data masking capabilities in ADAF MD make use of the same XACML-powered authorization engine, which means data masking in this context can be made subject to complex business rules expressed in the XACML language. The expressiveness of this policy language enables the implementation complex business rules that are far more advanced than the relatively simple rules that data masking solutions typically are based on so far.

This post explains how to perform a custom data masking on a column using ADAF MD.
