A Security Architecture for Computational Grids

by Ian Foster , Carl Kesselman, Gene Tsudik, Steven Tuecke , 1998
"... State-of-the-art and emerging scientific applications require fast access to large quantities of data and commensurately fast computational resources. Both resources and data are often distributed in a wide-area network with components administered locally and independently. Computations may involve ..."

The anatomy of the Grid: Enabling scalable virtual organizations.

by Ian Foster , • , Carl Kesselman , Steven Tuecke - The International Journal of High Performance Computing Applications , 2001
"... Abstract "Grid" computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications, and, in some cases, high-performance orientation. In this article, we define this new field. First, ..."

access, resource discovery, and other challenges. It is this class of problem that is addressed by Grid technologies. Next, we present an extensible and open Grid architecture, in which protocols, services, application programming interfaces, and software development kits are categorized according

Query evaluation techniques for large databases

by Goetz Graefe - ACM COMPUTING SURVEYS , 1993
"... Database management systems will continue to manage large data volumes. Thus, efficient algorithms for accessing and manipulating large sets and sequences will be required to provide acceptable performance. The advent of object-oriented and extensible database systems will not solve this problem. On ..."

A data-oriented (and beyond) network architecture

by Teemu Koponen, Andrey Ermolinskiy, Mohit Chawla, Kye Hyun Kim, Ion Stoica, Byung-gon Chun, Scott Shenker - In SIGCOMM , 2007
"... The Internet has evolved greatly from its original incarnation. For instance, the vast majority of current Internet usage is data retrieval and service access, whereas the architecture was designed around host-to-host applications such as telnet and ftp. Moreover, the original Internet was a purely ..."

Ontology-Based Matching of Security Attributes for Personal Data Access in e-Health

by Ioana Ciuciu, Brecht Claerhout, Louis Schilders, Robert Meersman
"... Abstract. This paper discusses an interoperability solution (tool) for the internal management of a policy decision engine located at the level of the au-thorization layer of a service oriented environment. The tool aims to support federated access control in the context of distributed architectures ..."

into the attributes recognized by the central (Master Policy Decision Point) vocabulary based on a security ontology and its domain-specific extensions which provides semantic reasoning services. The approach is validated in an e-Health scenario for the access of patient data for diabetes patient monitoring

A Secure e-Health Architecture based on the Appliance of Pseudonymization

by unknown authors
"... Abstract — Due to the cost pressure on the health care system an increase in the need for electronic healthcare records (EHR) could be observed in the last decade, because EHRs promise massive savings by digitizing and centrally providing medical data. As highly sensitive patient information is exch ..."

data privacy and keeps the access to health data under strict control of the patient. This paper introduces the new architecture PIPE (Pseudonymization of Information for Privacy in e-Health) that integrates primary and secondary usage of health data. It provides an innovative concept for data sharing

Secure and Scalable Cloud-based Architecture for e-Health Wireless sensor networks

by Ahmed Lounis, Abdelkrim Hadjidj, Abdelmadjid Bouabdallah, Yacine Challal, Université De Technologie De Compiègne
"... Abstract—There has been a host of research works on wireless sensor networks for medical applications. However, the major shortcoming of these efforts is a lack of consideration of data management. Indeed, the huge amount of high sensitive data generated and collected by medical sensor networks intr ..."
Abstract - Cited by 3 (0 self) - Add to MetaCart
introduces several challenges that existing architectures cannot solve. These challenges include scalability, availability and security. In this paper, we propose an innovative architecture for collecting and accessing large amount of data generated by medical sensor networks. Our architecture resolves all

A PROPOSED SECURITY ARCHITECTURE FOR ESTABLISHING PRIVACY DOMAINS IN E-HEALTH CLOUD

by Al-khanjari Z, Al-ani A
"... Information and communication technology (ICT) are becoming a natural part in healthcare. Instead of keeping patient information inside a written file, you can find all information stored in an organized database as well defined files using a specific system in almost every hospital. But those files ..."
Abstract - Add to MetaCart
an access to patient record everywhere, so patient history will be clear which helps doctors in giving the right decision. We present security architecture for establishing privacy domains in e-Health bases. In this case, we will improve the availability of medical data and provide the ability for patients

CodeBlue: An ad hoc sensor network infrastructure for emergency medical care

by David Malan, Thaddeus Fulford-jones, Matt Welsh, Steve Moulton - In International Workshop on Wearable and Implantable Body Sensor Networks , 2004
"... Sensor devices integrating embedded processors, low-power, lowbandwidth radios, and a modest amount of storage have the potential to enhance emergency medical care. Wearable vital sign sensors can track patient status and location, while simultaneously operating as active tags. We introduce CodeBlue ..."
