Security issues for the Semantic Web

Abstract Security is one of the key requirements in the current state of technological advancement. Sharing of data at any level has been deemed unfit from time to time due to various security breaches. Healthcare sector is not an exception. Confidential medical data of individuals can be leaked and various techniques are then deployed by the third party to spam the individuals. This information can be further used by medical agencies for their personal benefits. In the current scenario, remotely monitoring of patients has gained some sort of momentum due to its many potential features. The term Semantic Web refers to a web where all data in a database are linked over the network of computers. It enables users to store their confidential and private data over the web, define some meaningful vocabulary for the created data, and formulate some rules to handle the stored data. Some of the technologies used to link the data in the Semantic Web are Resource Description Framework, SPARQL, Ontology Web Language, and Simple Knowledge Organization System. Likewise, the security issues of the Semantic web are of great concern in the current scenario. In this chapter, we have analyzed critically various security protocols as employed as of now in semantic web used in healthcare and suggested some ways of potentially improving the protocols to make them more robust to be used for these services.
