In general, techniques for data access control are described, in which a policy engine implements and applies a declarative policy framework that can represent and reason about complex privacy policies. By using a common data model together with a formal shareability theory, this declarative policy framework enables the specification of expressive policies in a concise way without burdening the user with technical details of the underlying formalism of a data querying application or other knowledge representation scheme. The policy engine may be deployed as the policy decision point in a data access control system that also includes a policy enforcement point. The policy engine includes user interfaces for the creation, validation, and management of privacy policies. The policy engine may interface with systems that manage data requests and replies by coordinating policy engine decisions and access to databases.

The present invention relates to a method and apparatus for assisting with automated task management. In one embodiment, an apparatus for assisting a user in the execution of a task, where the task includes one or more workflows required to accomplish a goal defined by the user, includes a task learner for creating new workflows from user demonstrations, a workflow tracker for identifying and tracking the progress of a current workflow executing on a machine used by the user, a task assistance processor coupled to the workflow tracker, for generating a suggestion based on the progress of the current workflow, and a task executor coupled to the task assistance processor, for manipulating an application on the machine used by the user to carry out the suggestion.
