In some embodiments, a system includes a database of trust information that internalizes security and trust relationships between a first entity and a second entity in regards to scheduling, and a central trust manager operable to determine from the database of trust information whether a trust relationship exists between a first organization and a second organization, the central trust manager also being operable to provide availability information of a user of the first organization to a second user of the second organization, the central trust manager also being operable to determine whether the second user of the second organization is granted access to requested calendar data and the central trust manager also being operable to provide the requested calendar data.

Embodiments of the present invention provide a method, system and computer program product for aggregating database and component logic authorization rules in a multi-tier application. In an embodiment of the invention, a method for aggregating database and component logic authorization rules in a multi-tier application system can include aggregating role-based authorization rules for both a persistence layer and a logic layer of a multi-tier application in a unified policy, distributing the unified policy to both the persistence layer and the logic layer of the multi-tier application, transforming the unified policy into respectively a set of role based permissions for the persistence layer and a set of role based permissions for the logic layer, and applying the set of role based permissions for the persistence layer in the persistence layer, and the set of role based permissions for the logic layer in the logic layer of the multi-tier application.

Embodiments of the present invention address deficiencies of the art in respect to privacy data management and provide a novel and non-obvious method, system and computer program product for trusted statement verification for data privacy. In one embodiment of the invention, a method for trusted statement verification for data privacy can be provided. The method can include deducing a claim from an attribute for personal data for an end user, receiving a request from a personal data consumer to vouch for an assertion based upon the attribute, comparing the assertion to the claim, and providing a voucher for the assertion to the personal data consumer on behalf of the end user if the claim supports the assertion without revealing the attribute to the personal data consumer.
摘要:
A sending entity creates a structured document and communicates it to a receiving entity includes a transform to ensure document elements are not moved during communication. The structured document comprises a root element and a set of child elements. A child element is protected by a digital signature, prior to being positioned within the document. This element includes a sending entity security policy. The receiving entity includes a transform that determines whether the signed element is in a given position within the received document. The transform evaluates the data string against a set of ancestor elements of the signed element to determine whether the signed element is in the given position. If so, the transform preferably outputs the signed element itself. If the transform determines that the signed element has been moved, however, preferably it outputs a given value other than the signed element.

One aspect of the present invention can include a system, a method, a computer program product and an apparatus for federating policies from multiple policy providers. The aspect can identify a set of distinct policy providers, each maintaining at least one policy related to a service or a resource. A federated policy exchange service can be established that has a policy provider plug-in for each of the distinct policy providers. The federated policy exchange service can receive requests for policies from a set of policy requesters. Each request can include a resource_id or a service_id used to uniquely identify the service or resource. The federated policy exchange service can dynamically connect to a set of the policy providers to determine policies applicable to each request. For each request, results from the policy providers can be received and processed to generate a response. The federated policy exchange service can provide the response to each policy requestor responsive in response to each response.

Techniques are disclosed for achieving context-sensitive confidentiality within a federated environment for which content is aggregated in a distributed Web portal (or similar aggregation framework), ensuring that message portions that should be confidential are confidential to all entities in the federated environment except those entities to which the message portions may properly be divulged. The federation may comprise an arbitrary number of autonomous security domains, and these security domains may have independent trust models and authentication services. Using the disclosed techniques, messages can be routed securely within a cross-domain federation (irrespective of routing paths), thereby ensuring that confidential information is not exposed to unintended third parties and that critical information is not tampered with while in transit between security domains. Preferred embodiments leverage Web services techniques and a number of industry standards.

Embodiments of the present invention provide a method, system and computer program product for declarative instance based access control for persistent application resources in a multi-tier application. In one embodiment of the invention, a method for instance based access control in a persistent application resource can be provided. The method can include creating one or more instances of an persistent application resource for a particular user or based on attributes of the user, coupling the instance(s) of the persistent application resource to a database implementing row-level access control, initializing access to the database according to a role or attribute for the particular user, and accessing a restricted set of data in the database through the instance(s) of the persistent application resource.

Embodiments of the present invention address deficiencies of the art in respect to access control and provide a method, system and computer program product for access control management for a collection of heterogeneous application components. In a first embodiment, a data processing system for role-based access control management for multiple heterogeneous application components can include at least one business role descriptor associating a business role with multiple, different application roles for corresponding, disparate application components. The system also can include at least one access policy associating a user with the business role. Finally, the system can include policy deployment logic include program code enabled to process the access policy to assign the user to the different application roles in the disparate application components.
