Popis
Shrnutí:XML can supply the standard data type in information exchange format on a lot of data generated in running database or applied programs for a company by using the advantage that it can describe meaningful information directly. Accordingly since there are increasing needs for the efficient management and telemedicine security of the massive volume of XML data, it is necessary to develop a secure access control mechanism for XML. The existing access control has not taken information structures and semantics into full consideration due to the fundamental limitations of HTML. In addition, access control for XML documents allows read operations only, and there are problems of slowing down the system performance due to the complex authorization evaluation process. To resolve this problem, this paper designs and builds a XACS (XML Access Control System), which is capable of making fined-grained access control. This only provides data corresponding to its users’ authority levels by authorizing them to access only the specific items of XML documents when they are searching XML documents in telemedicine. To accomplish this, XACS eliminates certain parts of the documents that are inaccessible and transmits the parts accessible depending on the users’ authority levels. In addition, it can be expanded to existing web servers because XML documents are used based on the normal web sites. The telemedicine secure and the guidelines are provided to enable quick and precise understanding of the information, and thus the safety enhancement gets improved. Ultimately, this paper suggests an empirical telemedicine application to confirm the adequacy and validity using the proposed method.
