Health care domain have attracted considerable amount of research fields. One of the field that has a drastic focus on health care domain is data mining. Mainly health care system focuses on some data mining theories like classification, clustering etc.

Video streaming dominates the Internet traffic, a trend that is expected to increase in the next years. End users expect to access video content, regardless of their device, connection type and location. On the other hand, content providers set strict security requirements regarding the protection of their content, making up an overall difficult and challenging context for Over‐the‐Top service providers. A miscellany of proprietary approaches tries to address these issues, providing, however, only partial solutions, and composing a domain, highly fragmented by non‐interoperable products. In this paper, we propose an architecture that utilises Information‐Centric Networking (ICN) in order to provide scalable and efficient video distribution, and Attribute‐Based Encryption (ABE) to securely distribute this content in the ICN environment. ABE is incorporated into Digital Rights Management (DRM) schemes. We present the video license acquisition process, with a focus on orchestrating multiple authorities; subsequently, the video distribution over ICN is demonstrated, and finally, we investigate user revocation techniques in the ABE and ICN context and adopt the most appropriate one.

This paper presents a novel routing scheme for content-centric networks, which does not just depend on the names of the packets to retrieve the routing paths, but goes one step beyond and incorporates semantics as a fundamental criterion to decide where to keep and, hence, request information. Going from a naming scheme to the actual protocol architecture, this paper is an endeavor to enhance semantics in the network layer and, through that, to illustrate the new possibilities offered by content-centric networks to introduce an entirely new idea in communications.

The Web is rapidly becoming the prime medium for human socialization. The resources that enable that process (social web sites, blogs, media objects, etc.) present growing complexity and, collectively, weave an ever more intricate web of relationships. Current technology for declaring those relationships is predominantly implicit, ambiguous and semantically poor. As a consequence, their automatic assessment is complex and error prone, preventing the satisfaction of users' needs such as effective semantic searches. To address these limitations, whilst enabling the explicit declaration of semantically unambiguous relationships between digital resources, a solution employing structured semantic descriptors and ontologies was conceived, based on MPEG-21. This paper explains the functioning of the devised mechanism, and goes beyond that, into the definition of two novel employment venues for it, at the service of two real-world usage scenarios. These demonstrate the mechanism's added value as a powerful alternative for the semantically aware interconnection of web resources, and highlight the increased QoE that said mechanism enables.
