And Storage

Copyright protection of digital content has become a problem not only for web content providers but also for ordinary web users who like to publish their digital contents on social or user generated content platforms. Among the possible solutions to such a problem, digital watermarking, in conjunction with watermarking protocols, appears to be a valid alternative to current DRM (digital rights management) systems. In fact, watermarking based solutions insert perceptually invisible copyright information into the copies of contents published or distributed on the web in order to track them. Such insertions are carried out according to the watermarking protocols, which have evolved over the years from the classic “buyer and seller” paradigm into a simpler and versatile “buyer friendly” and “mediated” approach. However, such an approach cannot exploit the new technologies that characterize the current Internet. This paper presents a new watermarking protocol able to adapt the “buyer friendly” and “mediated” approach to the use of innovative technologies such as cloud platforms and blockchain. In this way, (1) content providers and common web users can take advantage of the computing and storage resources made available by cloud platforms; (2) the involvement of trusted third parties in the protocols can be reduced by using blockchain without complicating the protection scheme. In fact, these two goals make the protocol particularly suited for the current Internet.

New System

Digital Rights Management (DRM) technology is used to control access to copyrighted digital content. Apple employs a DRM system known as Fairplay in its iTunes online music store. Users communicate with the centralized iTunes server to download, purchase, play, and preview digital content. The iTunes music store has the potential disadvantage of a bandwidth bottleneck at the centralized server. Furthermore, this bandwidth bottleneck problem will escalate with increasing popularity of online music and other digital media, such as video. In this chapter, we analyze the Fairplay DRM system. We then consider a modified architecture that can be employed over existing peer-to-peer (P2P) networks. Our new system, P2PTunes, is designed to provide the benefits of a decentralized P2P network while providing DRM content protection that is at least as strong as that found in Fairplay.
