Abstract: A system separately designates security requirements for each of a plurality of methods invoked on a server. The system includes a security class library and an execution unit. The security class library stores a plurality of security objects that correspond to the plurality of methods. Each of the security objects stores the security requirements for the corresponding method. The execution unit receives from a client a method invocation request that includes security requirements of the client. From the request, the execution unit identifies one of the security objects in the security class library that corresponds to the requested method, and determines whether to invoke the requested method based on a comparison of the client security requirements and the security requirements stored in the security object.

Abstract: A novel elastomeric composition of matter comprises a rubber latex and a masterbatch comprising a therapeutic agent in a therapeutically effective amount, a carrier component, titanium dioxide, and clay. A process for the preparation of a novel elastomeric composition of matter containing a therapeutic agent includes the steps of preparing a masterbatch containing a therapeutic agent, adding the masterbatch to a rubber latex and thereafter forming and curing a desired product therefrom. The composition is useful in the manufacture of rubber goods such as surgical and medical products which can be single or multilayered.
