Quick and easy masking

I had a request from a client a while back regarding masking of data. They had an application with sensitive data in the Production environment (where access and audit were very tightly controlled) but the issue was how to respect that sensitivity in non-Production environments whilst still preserving full size data sizes for application testing.

After some conversations about requirements, it turned out that since (even in non-Production environments) all access to application components was logged and audited, the issue was simply protecting against “inadvertent” access to sensitive data. For example, in the application, if I searched for “males with black hair with an interest in technology” I should never see the name “Connor McDonald” on screen in the results, because simply viewing that data could be treated as a breach of privacy.
