OBJECTIVE To examine the impact of Medicaid prior authorization for atypical antipsychotics on the prevalence of schizophrenia among the prison population. Study DESIGN We collected drug-level information on prior authorization restrictions from Medicaid programs in 30 states to determine which states had prior authorization requirements before 2004. We linked the regulatory data to a survey ...

Signaling layer protocols specified within the Next Steps in Signaling (NSIS) framework may rely on the General Internet Signaling Transport (GIST) protocol to handle authorization. Still, the signaling layer protocol above GIST itself may require separate authorization to be performed when a node receives a request for a certain kind of service or resources. This document presents a generic mo...

Software Services based Application Service Provider pattern is an important method in constructing enterprise applications, which integrate business systems with different authentication mechanism. So there are questions such as repeated authentication and authorization, difficulties in authorization management, difficult to describe security information interoperability. This paper proposes a...

A procedure model for the development of an authorization architecture, which spans different IT systems and organizational units, is presented. Based on a conceptual discussion of authorization and authorization architecture, existing approaches are discussed. As basic requirements for authorization architecture, a theoretical foundation and a transparent derivation of the procedure model and ...

Decoupling authorization logic from application logic allows applications with fine-grain access control requirements to be independent from a particular access control policy and from factors that are used in authorization decisions as well as access control models, no matter how dynamic those polices and factors are. It also enables elaborate and consistent access control policies across hete...

E-business applications need robust and powerful mechanisms to authorize security-critical actions. This actions can be very complex, since they can be initiated not only by human users but also by applications or software agents. Existing authorization mechanisms do not scale for large number of users if the trust relations are dynamic and fail to provide reliable authorization among strangers...

Consider interaction of principals where each principal has its own policy and different principals may not trust each other. In one scenario the principals could be pharmaceutical companies, hospitals, biomedical labs and health related government institutions. In another scenario principals could be navy fleets of different and not necessarily friendly nations. In spite of the complexity of i...
