document: A uniform framework for regulating service access and information release on the Web The widespread use of Internet-based services is increasing the amount of information -LRB- such as user profiles -RRB- that clients are required to disclose . This information demand is necessary for regulating access to services , and functionally convenient -LRB- e.g. , to support service customization -RRB- , but it has raised privacy-related concerns which , if not addressed , may affect the users disposition to use network services . At the same time , servers need to regulate service access without disclosing entirely the details of their access control policy . There is therefore a pressing need for privacy-aware techniques to regulate access to services open to the network . We propose an approach for regulating service access and information disclosure on the Web . The approach consists of a uniform formal framework to formulate - and reason about - both service access and information disclosure constraints . It also provides a means for parties to communicate their requirements while ensuring that no private information be disclosed and that the communicated requirements are correct with respect to the constraints
