Efficient Access Control Mechanism for XML Databases Using Web Services

Abstract

XML document are frequently used inapplication such as business transaction andmedical record involving sensitive information.Typically, parts of xml documents should be visibleto users depending on their roles. And then accesscontrol on the basis of data location or value in anXML document is essential. Additionally, webservices are application components that aredesigned to support interoperable machine-tomachineinteraction over a network. Thisinteroperability is gained through a set of XMLbasedopen standards, such as the Web ServicesDescription Language (WSDL), the Simple ObjectAccess Protocol (SOAP), and Universal Description,Discovery, and Integration (UDDI). These standardsprovide a common and interoperable approach fordefining, publishing, and using web services. Thispaper describes the design of an Access ControlSystem using Web Services for xml data and accessright management. And then we present an overviewof the access control mechanism to build accesscontrol services around a Web Services model andaddress how to increase sever throughput usingaccess control rules functions that are managementseparately from the server database using webservice
