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.

Three critical issues—a dramatic expansion of the scope, duration, and punitive nature of copyright laws; the ability of Digital Rights Management (DRM) systems to lock-down digital content in an unprecedented fashion; and the erosion of Net neutrality, which ensures that all Internet traffic is treated equally—are examined in detail and their potential impact on libraries is assessed. How legislatures, the courts, and the commercial marketplace treat these issues will strongly influence the future of digital information for good or ill.

In the wake of the Digital Millennium Copyright Act, of 1998, Digital Rights Management systems are beginning to provide copyright protection for digital content which magazine and book publishers, music companies, software and game producers, and business-to-business participants place online. Creators and providers of digital content are now increasingly able to control end users’ use of, and accessibility to, their products and stand to gain huge profits from this capability. However, as DRM technologies evolve and develop, so does end user concern about restrictions to their access to, and use of, information. The DRM industry will have to provide a balance between fair compensation for the creators of digital content and the rights of end-users to access and use the information they need.

Rights Management

Digital rights management (DRM) provides digital content creators and owners with a range of controls over how their information resources may be used. It is a fairly young discipline yet is becoming increasingly important as digital content can be copied and distributed so easily that the piracy of them is growing critical. In addition, with the rapid adoption of the Internet as an e-content delivery channel, complex DRM systems are required to protect the digital content besides the distribution channel. Risking their intellectual property (IP) rights, many major e-content providers are relying on DRM to not only protect the packaged digital products, but also to promote the e-content market over the Internet. As a multidisciplinary technology, DRM has advanced innovative research and development in various fields such as biometrics, watermarking, security protocols, smart-card technology, forgery detection, and secure collaboration and data sharing. Commercially, DRM provides the e-content market with a significant impetus to grow, where secure e-content distribution is essential. Despite its short history, many DRM tools have already been developed by IBM, Sony, Real Networks, Intertrust, and Thomson. These products need be compatible with existing standards for contents, consumer electronics, and often times, different DRM systems. Standardization efforts in industry are ongoing to ensure the interoperability of DRM products and services. Another important impetus is the legal and regulatory framework. Technical measures provide an effective hurdle for limiting abuse, but legal actions against violators can prevent organized piracy from infringing. With a properly integrated legal, technological, and commercial framework, we expect that the DRM products and services will greatly foster the growth of the e-content market that is eagerly awaited by content providers and consumers. Without proper DRM technologies and laws, the creative industries that create digital products such as DVDs, business software, music recordings, theatrical films, and digital TV programs will suffer from piracy and would be reluctant to support Web-based commerce. The socioeconomic impact of DRM is huge. In this article, DRM techniques using cryptography, data hiding, and biometrics are discussed. Also covered are the standardization issues, emerging trends, and challenges in DRM-related technologies, commerce, and legislative regulations.

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.

With the remarkable growth of Internet and multimedia applications, production and distribution of digital media has become exceedingly easy and affordable. Applications such as distance education, e-commerce, telemedicine, digital library, and live audio/video broadcast activities require distribution and sharing of digital multimedia contents. Consequently, maintaining the quality of service of the applications and the rights of the content owner as well as enforcing a viable business model among the producer, consumer, and distributor of digital contents has become an increasingly challenging task, leading to a contentious area called digital rights management (DRM). This chapter presents how digital watermarking (DWM) technology can addresses part of this DRM problem of secure distribution of digital contents.

Rights Management

Digital Rights Management (DRM) is concerned with the ownership of digital information and access to that information. Organizations and individuals increasingly seek to prevent unauthorized or inadvertent release of owned, proprietary, or sensitive information. A variety of technologies are available to prevent the piracy and verify the true owners of digital content, unfortunately specifics of these technologies are often proprietary. Content can be protected by a variety of encryption techniques for the storage and transmission of digital information yet; these same techniques can limit access and usability of digital content. This chapter discusses the general state of digital security and technologies in use followed by a discussion of future directions for digital security research and practice.

With the rapid popularity of P2P networks, the demand for digital rights management (DRM) in P2P mode is increasing quickly. The research on issuance of digital content licenses is the key issues in DRM. As for the centralized authorization systems, the security and the efficiency have certain defects. An improved distributed license authorization system is presented in this paper. And the nodes in the system are divided into six kinds of roles in accordance with theirs functions and a new non-interactive verifiable secret sharing protocol is introduced. Because of the adoptions of threshold secret sharing mechanism and the independent synthesis peers, the system security is improved in the transmission of digital content license and the burden of nodes is reduced in P2P networks. Each license authorization node gets the correct secret sharing by the non-interactive verifiable secret sharing protocol.

Cultural Relics

The digital rights management of museums is a mechanism that protects digital content from being abused by controlling and managing its usage rights. Traditional museums attach importance to the collection, display, research, and education functions of “objects”. In response to natural or man-made disasters, people are often caught off guard, destroying material, intangible assets, and spiritual symbolism. Therefore, with the advancement of digital technology, this research is based on the mechanism of blockchain, through the authorization of cryptographic proxy re-encryption, and proposes a new method for the preservation and authorization of digital content in museums, which can effectively display, store, and promote “important cultural relics and digital archives”. In this research, the Elliptic Curve Digital Signature Algorithm (ECDSA), blockchain, and smart contracts are used to design a sustainable and traceable cultural relic exhibition mechanism. The proposed scheme achieves publicly verifiable, transparency, unforgeability, traceability, non-repudiation, standardization of stored data, timeliness, etc., goals. It is the museum’s preservation and innovation approach for the unpredictable future. Through appropriate preservation and management mechanisms, it has extremely important practical significance for the protection of museum collections, the inheritance of historical and cultural heritage, and the expansion of social education.
