摘要： A dynamic authorization callback mechanism is provided that implements a dynamic authorization model. An application can thus implement virtually any authorization policy by utilizing dynamic data and flexible policy algorithms inherent in the dynamic authorization model. Dynamic data, such as client operation parameter values, client attributes stored in a time-varying or updateable data store, run-time or environmental factors such as time-of-day, and any other static or dynamic data that is managed or retrievable by the application may be evaluated in connection with access control decisions. Hence, applications may define and implement business rules that can be expressed in terms of run-time operations and dynamic data. An application thus has substantial flexibility in defining and implementing custom authorization policy, and at the same time provides standard definitions for such dynamic data and policy.

摘要： An authorization handle is supported for each access policy determination that is likely to be repeated. In particular, an authorization handle may be assigned to access check results associated with the same discretionary access control list and the same client context. This likelihood may be determined based upon pre-set criteria for the application or service, based on usage history and the like. Once an access policy determination is assigned an authorization handle, the static maximum allowed access is cached for that policy determination. From access check to access check, the set of permissions desired by the client may change, and dynamic factors that might affect the overall privilege grant may also change; however, generally there is still a set of policies that is unaffected by the changes and common across access requests. The cached static maximum allowed access data is thus used to provide efficient operations for the evaluation of common policy sets. In systems having access policy evaluations that are repeated, authorization policy evaluations are more efficient, computer resources are free for other tasks, and performance improvements are observed.

摘要： A method for immunoassay of a viral antigen is performed on a membrane precoated with an inert protein. Nonimmunological capture of antigen takes place by absorption onto the coated membrane. Captured antigen binds to a tracer which includes a label conjugated to a specific antibody, the inert protein concomitantly inhibiting nonspecific binding of tracer. The label may be an enzyme which converts a substrate to a detectable product or converts a blocked inhibitor to an inhibitor whereby a second enzyme is inhibited from converting a substrate to a product. The invention includes a kit of materials for performing an assay in accordance with the method of the invention.
