In this paper we present a systematic categorization of the user access authorization exceptions which may occur in conventional role-based access control models. We propose a slightly revised NIST RBAC model which allows us to express all the authorization exceptions we consider. We give a formal definition of the model and show how it can be implemented in DATALOG with negation to give simple...
Prior Authorization Information Pre-service approval is required for all inpatient services for all products. See below for situations where prior authorization may be required or may not be required for outpatient services. Yes indicates that prior authorization is required. No indicates that prior authorization is not required. N/A indicates that this service is primarily performed in an inpa...

As a security mechanism, authorization is to provide access control to the system resources according to the polices and rules specified by the security strategies. Either by update or in the initial specification, conflicts in authorization is an issue needs to be solved. In this paper, we propose a new approach to solve conflict by using prioritized logic programs and discuss the uniqueness o...

Authorization protects application resources by allowing only authorized entities to access them. Existing authorization solutions are widely based on the request-response model, where a policy enforcement point intercepts application requests, obtains authorization decisions from a remote policy decision point, and enforces those decisions. This model enables sharing the decision point as an a...
BACKGROUND An increase in prior authorization (PA) requirements from health insurance companies is placing administrative and financial burdens on primary care offices across the United States. As time allocation for these cases continues to grow, physicians are concerned with additional workload and inefficiency in the workplace. The objective is to estimate the effects of practice characteris...
As part of the access control process an authorization decision needs to be taken based on a certain authorization model. Depending on the environment different models are applicable (e.g., RBAC in organizations, MAC in the military field). An authorization model contains all necessary elements needed for the decision (e.g., subjects, objects, and roles) as well as their relations. As these ele...
Current credit card authorization was developed on single-threaded model whereby authentication process takes longer time to respond due to sequential process of card’s risk management profile and its limitation of handling huge number of simultaneous transactions at single point of time. As a result, the performance of the authorization system was affected during peak hours. This study present...
