Music Distribution

The popularity of peer-to-peer (P2P) file sharing software has created a pressing need for digital music providers to resolve copyright and piracy problems of disseminating digital music through the Internet. Digital Rights Management (DRM) technology ensures protection of rights for distributed music over the Internet. Existing DRM systems emphasize protection based on business-to-consumer (B2C) distribution model, but do not tackle protection on a consumer-to-consumer (C2C) distribution model. This paper proposes a license management model to support not only typical music distribution models from music distributor to consumer (B2C), but also peer consumer to peer consumer (C2C) distribution model. The proposed license management model consists of two types of licenses, namely official licenses and peer licenses. These licenses are to be implemented in XrML. The concepts of these licenses facilitate both B2C and C2C distribution models. Functionality tests of the proposed model with certain common peer-to-peer sharing activities have been conducted.

Music Distribution

Nowadays, there is a great increase in music distribution over the Internet. This phenomenon is common in many countries and therefore involves many issues such as: ways of distribution, music format, organizing music and copyright issues. The revolution in music prototypes (especially the MP3 music format) urged many people to turn to the Internet for free and easy-to-find music. Music files can be downloaded easily from the Internet anywhere in the world and be burned into a CD or DVD or transferred to a friend via usb-sticks. Music is also widely available as streams in Internet trough various services such as MySpace, YouTube and Spotify. Internet also is full of questions what is legal and what is not, because exchange of files is hard to supervise and the laws between countries also differ. All the legal services are constructed around a digital music library, containing millions of songs. Vast music libraries are easily accessed through Internet from users and serve as the ultimate way to find and listen to the music they desire. In this chapter, some representative popular music libraries are presented. Moreover, the interaction between the user and a music repository or a music store (a web site that sells music over the Internet) is another subject presented in this chapter. In section 1, terms and definitions related to digital music libraries are explained. Section 2 presents some popular music libraries, while section 3 presents some popular Internet music stores. Finally, a special version of a digital music library in streaming format (Internet Radio) is presented in section 4.

Media Objects

In 1999, exchanges of digital media objects, especially files of music, came to constitute a significant portion of Internet traffic, thanks to a new set of technologies known as peer-to-peer (P2P) file-sharing systems. The networks created by software applications such as Napster and Kazaa have made it possible for millions of users to gain access to an extraordinary range of multimedia files. However, the digital product characteristics of portability and replicability have posed great challenges for businesses that have in the past controlled the markets for image and sound recordings. ‘Peer-to-peer’ is a type of network architecture in which the various nodes may communicate directly with other nodes, without having to pass messages through any central controlling node (Whinston, Parameswaran, & Susarla, 2001). The basic infrastructure of the Internet relies on this principle for fault tolerance; if any single node ceases to operate, messages can still reach their destination by rerouting through other still-functioning nodes. The Internet today consists of a complex mixture of peer-to-peer and client-server relationships, but P2P file-sharing systems operate as overlay networks (Gummadi, Saroiu, & Gribble, 2002) upon that basic Internet structure. P2P file-sharing systems are software applications which enable direct communications between nodes in the network. They share this definition with other systems used for purposes other than file sharing, such as instant messaging, distributed computing, and media streaming. What these P2P technologies have in common is the ability to leverage the combined power of many machines in a network to achieve results that are difficult or impossible for single machines to accomplish. However, such networks also open up possibilities for pooling the interests and actions of the users so that effects emerge which were not necessarily anticipated when the network technology was originally created (Castells, 2000). In a narrow sense, P2P file-sharing systems refer to applications that exchange content over computer networks where the nodes act both as client and server machines, requesting and serving files (e.g., Kazaa, BitTorrent). In a wider sense, P2P file-sharing systems also include any application that lets peer users exchange digital content among themselves (e.g., YouTube, Flickr).

This chapter presents a model enabling content providers to successfully sell digital music. We show that content providers must overcome three main hurdles to successfully sell digital music. The first is to establish an efficient and economically viable distribution channel. Second, they need to develop a secure and interoperable framework for protecting copyrighted digital music from piracy by integrating Digital Rights Management Systems into the distribution channel. The third hurdle is to set-up a robust payment mechanism that meets the content providers’ needs for revenue capturing and the consumers’ needs for hassle-free and legal content acquisition and usage. This chapter finally presents a DRM supported peer-to-peer network which could address and overcome the three hurdles. We conclude that a DRM supported P2P network gives content providers as well as consumers the secure, legal and most cost-efficient and user friendly digital distribution channel they have been searching for.

The Cost

In contrast to what is happening in the Internet-based scenario, the music market in the mobile scenario is far from being considered a large success. Several studies state that excessive downloading time and high cost are the main burdens. Motivated by the growth of social and mobile applications, in this paper we propose an approach that aims at reducing both the downloading time and the cost to get digital music when acquired in the mobile scenario. The proposed architecture exploits the usage of personal communication technologies embedded in cellphones (e.g., Bluetooth and Wi-Fi) to couple the current distribution model (mainly based on 3G networks), so as to provide a multichannel distribution model where users are free to redistribute digital music. The architecture includes a license-based security mechanism that prevents unauthorized usage of digital music, and makes use of an incentive mechanism to stimulate and reward the music distribution among customers. By analyzing pros and cons of the music distribution chain, results show that the proposed architecture might help in reducing both the downloading time and the cost to get digital music when acquired in the mobile scenario. Therefore, it might be helpful to the success of the mobile music scenario.

Robust Prediction

Species distribution models have been used for various purposes, such as conserving species, discovering potential habitats, and obtaining evolutionary insights by predicting species occurrence. Many statistical and machine-learning-based approaches have been proposed to construct effective species distribution models, but with limited success due to spatial biases in presences and imbalanced presence-absences. We propose a novel species distribution model to address these problems based on bootstrap aggregating (bagging) ensembles of deep neural networks (DNNs). We first generate bootstraps considering presence-absence data on spatial balance to alleviate the bias problem. Then we construct DNNs using environmental data from presence and absence locations, and finally combine these into an ensemble model using three voting methods to improve prediction accuracy. Extensive experiments verified the proposed model’s effectiveness for species in South Korea using crowdsourced observations that have spatial biases. The proposed model achieved more accurate and robust prediction results than the current best practice models.

AbstractThe distribution of invasive plants depends on several environmental factors, e.g. on the distance from the vector of spreading, invaded community composition, land-use, etc. The species distribution models, a research tool for invasive plants spread prediction, involve the combination of environmental factors, occurrence data, and statistical approach. For the construction of the presented distribution model, the occurrence data on invasive plants (Solidagosp.,Fallopiasp.,Robinia pseudoaccacia,andHeracleum mantegazzianum) and Natura 2000 habitat types from the Protected Landscape Area Kokořínsko have been intersected in ArcGIS and statistically analyzed. The data analysis was focused on (1) verification of the accuracy of the Natura 2000 habitat map layer, and the accordance with the habitats occupied by invasive species and (2) identification of a suitable scale of intersection between the habitat and species distribution. Data suitability was evaluated for the construction of the model on local scale. Based on the data, the invaded habitat types were described and the optimal scale grid was evaluated. The results show the suitability of Natura 2000 habitat types for modelling, however more input data (e.g. on soil types, elevation) are needed.

Many advances have been done to allow groups of people to work together and collaborate in the Internet. Collaborative systems are characterized by the way participants interact. In many cases, equal standing members should cooperate in a non-authoritative environment, where no entity or authority is or should be in charge of regulating the group. Therefore, decentralized communication infrastructures have been hailed as promising alternatives. Recently, decentralized infrastructures based on P2P approaches have drawn the attention of the research community because of their benefits in terms of scalability, robustness, availability and potentials for leveraging computational resources distributed across the Internet. In this paper, a scalable peer-to-peer (P2P) communication Infrastructure for groupware applications is presented. It enables a large number of people to join and cooperate in a robust, decentralized and easy deployable way, without requiring high capacity servers or any other special network infrastructure. The communication infrastructure is based on a binary tree as overlay structure, which implements all groupware communication functionality, including membership management and packet forwarding, at application level, making it an inexpensive and fast deployable solution for equal standing members, such as home users with a domestic connection to the Internet. Two applications, one for synchronous groupware and the other for asynchronous collaboration, have been developed to validate the approach. Comparisons with other communication infrastructures in aspects such as end-to-end propagation delay, group latency, throughput, protocol overhead, failure recovery and link stress, show that our approach is a scalable and robust alternative.

Current trends towards the Future Internet are envisaging the conception of novel services endowed with context-aware and autonomic capabilities to improve end users’ quality of life. The Internet of Things paradigm is expected to contribute towards this ambitious vision by proposing models and mechanisms enabling the creation of networks of “smart things” on a large scale. It is widely recognized that efficient mechanisms for discovering available resources and capabilities are required to realize such vision. The contribution of this work consists in a novel discovery service for the Internet of Things. The proposed solution adopts a peer-to-peer approach for guaranteeing scalability, robustness, and easy maintenance of the overall system. While most existing peer-to-peer discovery services proposed for the IoT support solely exact match queries on a single attribute (i.e., the object identifier), our solution can handle multiattribute and range queries. We defined a layered approach by distinguishing three main aspects: multiattribute indexing, range query support, peer-to-peer routing. We chose to adopt an over-DHT indexing scheme to guarantee ease of design and implementation principles. We report on the implementation of a Proof of Concept in a dangerous goods monitoring scenario, and, finally, we discuss test results for structural properties and query performance evaluation.

e24036 Background: Multiple myeloma is a chronic progressive disease that calls for extended survivorship support post-diagnosis. Pre- COVID-19, the AMPATH Multiple Myeloma Program had created support groups for myeloma survivors and their caregivers that regularly met for health education, emotional support, and social opportunities. With the enforcement COVID-19 prevention and control protocols physical support group meetings became impossible. The program shifted to the online platform to sustain peer to peer support for myeloma patients and caregivers. We aim to describe challenges faced with online patient support group meetings as this has not been well documented in a resource-constrained setting. Methods: Myeloma patients and caregivers at Moi Teaching and Referral Hospital were contacted and a meeting date and time agreed. Participants were briefed on how to download and operate the zoom application in preparation for online meetings. A meeting link was shared with the expected attendees and a reminder sent two days before a meeting. Support group meetings were held for different groups among them myeloma survivors and caregivers. The meeting sessions were led by healthcare professionals – hematology consultants, social workers, nutritionist and psychosocial counsellors. Peer-to-peer sessions were also held. Results: Six online meeting sessions were held between June 2020 and December 2020. A total of 199 participants were expected to join the six different meetings but a low meeting turn-out of 25.6% was experienced. Participants were later contacted to unravel the reasons for a low turn-out. A total of 129 participants were contacted of which 88 responded. Out of the 88 respondents, 29% reported a tight work schedule, 25% short time meeting alerts, 20% did not have access to smartphones, and 8% had poor internet connectivity and another 8% reported no internet data bundles to connect to the internet. Conclusions: Low attendance of online meetings was observed. Participants cited scheduling and internet access as major obstacles to attending online support group meetings. Improved access to the internet through smartphones, reliable internet connection, and affordable data are needed in underserved communities to fully unlock the benefits of virtual platforms namely cost savings and effective information sharing.
