Survey on Decentralized Fingerprinting Solutions: Copyright Protection Through Piracy Tracing
computers Review Survey on Decentralized Fingerprinting Solutions: Copyright Protection through Piracy Tracing David Megías 1,* , Minoru Kuribayashi 2 and Amna Qureshi 1 1 Internet Interdisciplinary Institute (IN3), Universitat Oberta de Catalunya (UOC), CYBERCAT-Center for Cybersecurity Research of Catalonia, Castelldefels (Barcelona), 08860 Catalonia, Spain; [email protected] 2 Graduate School of Natural Science and Technology, Okayama University, Okayama 700-8530, Japan; [email protected] * Correspondence: [email protected] Received: 13 March 2020; Accepted: 30 March 2020; Published: 3 April 2020 Abstract: Copyright protection is one of the most relevant challenges in the network society. This paper focuses on digital fingerprinting, a technology that facilitates the tracing of the source of an illegal redistribution, making it possible for the copyright holder to take legal action in case of copyright violation. The paper reviews recent digital fingerprinting solutions that are available for two particularly relevant scenarios: peer-to-peer distribution networks and broadcasting. After analyzing those solutions, a discussion is carried out to highlight the properties and the limitations of those techniques. Finally, some directions for further research on this topic are suggested. Keywords: copyright infringement; piracy tracing; fingerprinting; peer-to-peer distribution; broadcasting 1. Introduction Nowadays, digital technologies allow users to generate near-perfect quality identical copies of the content at low costs. Therefore, the amount of the digital data that is illegally redistributed is growing, making businesses lose income. Content creators and multimedia producers are concerned about the consequences of illegal copying and redistribution on a massive scale. Consequently, the need for a protection system that can provide copyright protection by prosecuting unauthorized copying has arisen in recent years. -

State of Scholarship on Weblogs Definition of Weblogs
Introduction: Weblogs, Rhetoric, Community, and Culture Laura Gurak, Smiljana Antonijevic, Laurie Johnson, Clancy Ratliff, and Jessica Reyman, University of Minnesota State of scholarship on weblogs During the past two decades, we have witnessed the introduction of many new digital spaces for writing and communicating, from hypertext, to chat rooms, to newsgroups, to discussion boards, to MOOS and MUDs, to wikis, to peer-to-peer file sharing networks. The proliferation of new spaces for communicating via the Internet has evoked scholarship in the fields of communication, rhetoric, composition, and writing studies from researchers seeking to address the social, rhetorical, and discursive implications. Recently, there has emerged a new object for study of great rhetorical impact: the weblog. The scholarly exploration of weblogs is still new, having up to this point taken place at primarily at conferences. Some examples include Computers and Writing 2003 and 2004, Conference on College Composition and Communication 2004, the Association of Internet Researchers 2003, and Harvard Law School's BloggerCon, a conference devoted to "the art and science of weblogs." At these conferences, scholars have recognized that blogs are more than mere tools for communicating online; rather, they provide new possibilities for the Internet as a rhetorical space. Blogs, some would argue, have revolutionized the way we receive information and connect with each other in online environments. Enthusiasts claim that blogs allow anyone's voice to be heard and resist hierarchical modes of information dissemination and communication. While this idealist egalitarian model of the Internet has often been criticized, we find value in the power of blogs to forego the institutionalization of communicative practices and offer spaces for writing that are more collaboratively constructed than other online spaces, as bloggers freely link to, comment on, and augment each other's content. -

Twenty Years of Digital Audio Watermarking – a Comprehensive Review
Twenty Years of Digital Audio Watermarking – A Comprehensive Review Guang Huaa,∗, Jiwu Huangb, Yun Q. Shic, Jonathan Gohd, Vrizlynn L. L. Thingd aSchool of Electrical and Electronic Engineering, Nanyang Technological University, Singapore 639798. bCollege of Information Engineering, Shenzhen University, Shenzhen 518060, China. cDepartment of Electrical and Computer Engineering, New Jersey Institute of Technology, Newark, NJ 07102, USA. dCyber Security & Intelligence Department, Institute for Infocomm Research, Singapore 138632. Abstract Digital audio watermarking is an important technique to secure and au- thenticate audio media. This paper provides a comprehensive review of the twenty years’ research and development works for digital audio watermark- ing, based on an exhaustive literature survey and careful selections of rep- resentative solutions. We generally classify the existing designs into time domain and transform domain methods, and relate all the reviewed works using two generic watermark embedding equations in the two domains. The most important designing criteria, i.e., imperceptibility and robustness, are thoroughly reviewed. For imperceptibility, the existing measurement and control approaches are classified into heuristic and analytical types, followed by intensive analysis and discussions. Then, we investigate the robustness of the existing solutions against a wide range of critical attacks categorized into basic, desynchronization, and replacement attacks, respectively. This reveals current challenges in developing a global solution robust against all the attacks considered in this paper. Some remaining problems as well as research potentials for better system designs are also discussed. In addition, audio watermarking applications in terms of US patents and commercialized solutions are reviewed. This paper serves as a comprehensive tutorial for interested readers to gain a historical, technical, and also commercial view of digital audio watermarking. -
