{{Main|Data masking}}
[[Data masking]] of structured data is the process of obscuring (masking) specific data within a database table or cell to ensure that data security is maintained and sensitive information is not exposed to unauthorized personnel.<ref>{{cite web|url=http://mask-me.net/datamaskingwiki/wiki/26/data-masking-definition|title=Data Masking Definition|archive-url=https://web.archive.org/web/20170227062337/http://mask-me.net/datamaskingwiki/wiki/26/data-masking-definition|archive-date=2017-02-27|url-status=live|access-date=1 March 2016}}</ref> This may include masking the data from users (for example so banking customer representatives can only see the last four digits of a customer's national identity number), developers (who need real production data to test new software releases but should not be able to see sensitive financial data), outsourcing vendors, etc.<ref>{{Cite web
