The Effects of Digital Music Distribution" (2012)
Southern Illinois University Carbondale OpenSIUC Research Papers Graduate School Spring 4-5-2012 The ffecE ts of Digital Music Distribution Rama A. Dechsakda [email protected] Follow this and additional works at: http://opensiuc.lib.siu.edu/gs_rp The er search paper was a study of how digital music distribution has affected the music industry by researching different views and aspects. I believe this topic was vital to research because it give us insight on were the music industry is headed in the future. Two main research questions proposed were; “How is digital music distribution affecting the music industry?” and “In what way does the piracy industry affect the digital music industry?” The methodology used for this research was performing case studies, researching prospective and retrospective data, and analyzing sales figures and graphs. Case studies were performed on one independent artist and two major artists whom changed the digital music industry in different ways. Another pair of case studies were performed on an independent label and a major label on how changes of the digital music industry effected their business model and how piracy effected those new business models as well. I analyzed sales figures and graphs of digital music sales and physical sales to show the differences in the formats. I researched prospective data on how consumers adjusted to the digital music advancements and how piracy industry has affected them. Last I concluded all the data found during this research to show that digital music distribution is growing and could possibly be the dominant format for obtaining music, and the battle with piracy will be an ongoing process that will be hard to end anytime soon. -
The Business of Anti-Piracy: New Zones of Enterprise in the Copyright Wars
International Journal of Communication 6 (2012), 606–625 1932–8036/20120606 The Business of Anti-Piracy: New Zones of Enterprise in the Copyright Wars RAMON LOBATO1 JULIAN THOMAS Swinburne University of Technology From the perspective of copyright holders, piracy represents lost revenue. In this article we argue that piracy nevertheless has important generative features. We consider the range of commercial opportunities that piracy opens up outside of the media industries, identifying four overlapping fields of legal anti-piracy enterprise: technological prevention, revenue capture, knowledge generation, and policing/enforcement. Our analysis notes the commercialization of these activities and their close relationship with the informal media economy. A case study of recent “speculative invoicing” lawsuits demonstrates the extent of this commercialization and its detachment from the mainstream content industries. A key strategy of content industry groups during their long war on piracy has been to associate copyright infringement with lost revenue for artists, producers, and media businesses. Consumers are now familiar with the claim that piracy directly threatens the livelihoods of cultural workers and generates large profits for criminal organizations, bootleggers, and online intermediaries. Hence, the model of a zero-sum economic redistribution between two camps—producers and pirates—with the latter cannibalizing the revenues of the former. This is an ever-present theme in anti-piracy discourse, exemplified by the Motion Picture Association of America’s claim that “copyright theft means declining incomes, lost jobs and reduced health and retirement benefits” (MPAA, 2010, p. 2) and by the Australian Federation Against Copyright Theft’s warning that “film and TV piracy rips more than $230 million out of the Australian economy each year” (AFACT, 2008, p. -

Title: P2P Networks for Content Sharing
Title: P2P Networks for Content Sharing Authors: Choon Hoong Ding, Sarana Nutanong, and Rajkumar Buyya Grid Computing and Distributed Systems Laboratory, Department of Computer Science and Software Engineering, The University of Melbourne, Australia (chd, sarana, raj)@cs.mu.oz.au ABSTRACT Peer-to-peer (P2P) technologies have been widely used for content sharing, popularly called “file-swapping” networks. This chapter gives a broad overview of content sharing P2P technologies. It starts with the fundamental concept of P2P computing followed by the analysis of network topologies used in peer-to-peer systems. Next, three milestone peer-to-peer technologies: Napster, Gnutella, and Fasttrack are explored in details, and they are finally concluded with the comparison table in the last section. 1. INTRODUCTION Peer-to-peer (P2P) content sharing has been an astonishingly successful P2P application on the Internet. P2P has gained tremendous public attention from Napster, the system supporting music sharing on the Web. It is a new emerging, interesting research technology and a promising product base. Intel P2P working group gave the definition of P2P as "The sharing of computer resources and services by direct exchange between systems". This thus gives P2P systems two main key characteristics: • Scalability: there is no algorithmic, or technical limitation of the size of the system, e.g. the complexity of the system should be somewhat constant regardless of number of nodes in the system. • Reliability: The malfunction on any given node will not effect the whole system (or maybe even any other nodes). File sharing network like Gnutella is a good example of scalability and reliability. -

A Safe and Efficient Storage Scheme Based on Blockchain and IPFS for Agricultural Products Tracking
Journal of Computers Vol. 29 No. 6, 2018, pp. 158-167 doi:10.3966/199115992018122906015 A Safe and Efficient Storage Scheme Based on BlockChain and IPFS for Agricultural Products Tracking JinTao Hao*, Yan Sun, Hong Luo Beijing Key Laboratory of Intelligent Telecommunications Software and Multimedia, Beijing University of Posts and Telecommunications, Beijing 100876, China {haojintao, Sunyan, luoh}@bupt.edu.cn Received 9 January 2018; Revised 22 January 2018; Accepted 22 January 2018 Abstract. The adoption of agricultural products traceability management based on Internet of Things (IoT) technology provides excellent benefits for the current food safety issues. The provenance data can demonstrate agricultural products movement process from the countryside to the dining table. However, the massive provenance data incurs an inefficient query. Meanwhile, the provenance data can be tampered deliberately which affect food safety. There are seldom reported approaches that can solve the above problem effectively. In this paper, we propose a data storage model based on Inter-Planetary File System (IPFS) and blockchain. First, IPFS is used to store video, images, and real-time monitoring data reported from the sensors. Then, in order to avoid a malicious user in case of data faking attack, we exploit the blockchain to store the IPFS hash address of the provenance data. Based on that, we design an authentication mechanism based on blockchain. It can verify the data and ensures effective data security. The experimental results show that the proposed approach can outperforms the existing methods. Keywords: agricultural products tracking, blockchain, IPFS, storage scheme 1 Introduction For agricultural products movement process from the countryside to the dining table, it needs to go through the cultivation, processing, transportation and sales.
