Using Workflow to Enhance Security in Federated Databases

摘要

A workflow system automates processes that occur during the daily operation of an organisation. The description of such a process inherently includes information about who needs to perform each step. It also includes information about when this subject has to perform that step. This information can be used to enhance security in the system. In particular the when information can be used to dynamically adapt security according to the current state of the workflow process.
