Digital Rights Protection Management of Web Portals Content
Without doubt one of the most important factors that contributed to the wide acceptance and popularity of Web portals is the potential for users to access a broad spectrum of information from a single access point, the Web portal itself. A Web portal, in such a way, aggregates information from multiple sources and makes that information available to various users. Regardless of whether the offered assets are hosted within the Web portal or whether the latter serves as a gateway to information services and resources located on the rest of the Internet, a Web portal is simultaneously an all-in-one Web site and a browsing guide to all available Internet information worldwide. Even though there is no definite taxonomy of portals, relevant labels such as government, community, enterprise, general and others are offered aiming at defining the Web portal with respect to its content and its target group. Summarizing, it could be assumed that a Web portal offers centralized access to all relevant content and applications (Tatnall, 2005). On the other hand, the ability to create, host and distribute digital material, one of the key features of digital technology that a Web portal utilizes and derives its huge success from, proved to be a double edged sword since it allowed zero cost reproduction of the digital material for purposes of piracy. Piracy of relevant digital material offered by a Web portal is common today and it has posed significant problems in terms of financial losses to the owners of digital content that is offered through it.
