The protection of private information revolves around the protection of data by making use of purposes. These purposes indicate why data is stored, and what the data will be used for (referred to as specification/verification phases).
In this article, the
active specification
of purposes during access requests is considered. In particular it is argued that the subject that wishes to get access to data should explicitly specify their reason for wanting the data; as opposed to verification taking place by implicit examination of the subject’s profile. To facilitate this
active specification
extensions to the SQL data manipulation language is considered.
