Evolution of healthcare systems and the constantly changing regulatory landscape continuously alter all facets of health information technology including access. Access to information systems must be controlled in order to protect privacy and confidentiality.

Proceedings of the 50th Annual Southeast Regional Conference, 2012
We propose a novel access control approach for pervasive computing environments. Sentential Access Control uses a constructed language similar to rudimentary English as the basis for intuitive context-aware security policy specification. The elements of sentences in this language map directly to fundamental security abstractions that allow us to apply ...

Access control by action control
Proceedings of the 13th ACM symposium on Access control models and technologies, 2008We address the problem of defining access control policies that may be used in the evaluation of requests made by client actors, in the course of e-trading, to perform actions on the resources maintained by an e-collective. An e-collective is a group of agents that may act individually or in conjunction with other agents to satisfy a client's request ...

Proceedings of the 1971 ACM SIGFIDET (now SIGMOD) Workshop on Data Description, Access and Control - SIGFIDET '71, 1971
The problems of authorization for a multiple-user resource sharing data processing system are discussed. The requirements for access of objects to other objects are covered in some detail. A model is then developed in which the above requirements are contained, in order to devise a conceptual framework for actual design of an access control system.

1985 IEEE Symposium on Security and Privacy, 1985
List-oriented systems integrate protection of an object with the object; ticket oriented systems delegate this responsibiIity to the call hierarchy. We argue that there are situations where integration of protection with the object is more natural, but Iist-oriented systems, due to the static and declarative nature of access-Iists, are too weak for any

A Middleware for Access Control
2012 13th International Conference on Parallel and Distributed Computing, Applications and Technologies, 2012In fine-grained access control, each data item has its own access control policy. The entity that wants to access a data item needs to provide its credentials to the policy enforcer to allow the enforcer to check the eligibility of the entity. This paper describes a middleware that relieves the programmers from carrying out the complicated fine-grained

18th Annual IEEE Symposium of Logic in Computer Science, 2003. Proceedings., 2003
Access control is central to security in computer systems. Over the years, there have been many efforts to explain and improve access control, sometimes with logical ideas and tools. This paper is a partial survey and discussion of the role of logic in access control.

Third International Conference on Information Technology and Applications (ICITA'05), 2005
Web services are designed to provide easier B2B integration among enterprises. UDDI defines a standard way for businesses to list their services and discover each other on the Internet. Due to security concerns organizations prefer to build their own private UDDI registries in their corporate network, which are only accessible by invited business ...

Proceedings of the annual conference on - ACM'73, 1973
A number of approaches have been developed to modularize parts of multiuser computer systems so that access to each part can be controlled. The devices of rings and capabilities are two examples. However, today's systems are notably incomplete and subject to defeat by determined and clever users.

Authorization and Access Control
2007Access control is the process of controlling every request to a system and determining, based on specified rules (authorizations), whether the request should be granted or denied. The definition of an access control system is typically based on three concepts: access control policies, access control models, and access control mechanisms.
