Blinding-Related Application Roles
To perform blinding-related operations on Table instances or outputs, a user must have the relevant blinding-related application role in addition to the required blinding-related object security privilege.
While a user group administrator assigns blinding-related object security privileges to a user in the context of a particular user group, blinding-related application roles are assigned to users by a system administrator and apply across Oracle LSH; they are not limited to a particular user group, object subtype, or Domain, for example.
