Blockchain technology has decentralized characteristics, and the development of blockchain technology provides an effective solution for the secure sharing of e-medical data. Many scholars have proposed e-medical data security sharing solutions based on blockchain technology, and these solutions have attempted to solve the security problems encountered in sharing traditional e-medical data. By summarizing and analyzing the schemes in this field, this study analyzes the advantages, disadvantages, and challenges that the current mainstream schemes have, mainly in terms of blockchain data security storage, access control security sharing, and so on, in order to promote the further development of the e-medical data security sharing scheme based on blockchain technology. This study analyzes the blockchain-based e-medical data security sharing scheme proposed by scholars by analyzing the blockchain technology, cryptography technology, smart contract technology, P2P network technology and other related topics. Through systematic analysis and comparison, it explores the challenges of the current research and provides references for the future proposals of blockchain technology-based schemes.

Delving into and Implementing Blockchain-related Technologies

Blockchain, birthed with the advent of Bitcoin, stands as a revolutionary decentralized digital ledger technology, casting light on the pathways of transparency, security, and efficiency across diverse sectors. Rooted in a blend of sophisticated technologies – from P2P network technology and encryption to timestamping – blockchain ensures secure, immutable transactions spanning its distributed nodes. Beyond its rudimentary role in Bitcoin, the technology has matured, fueling other digital currencies and leading to the emergence of private blockchains tailored for specific organizational processes. In its architectural framework, blockchain is layered with components like data, network, and consensus. Moreover, its versatile application layer introduces functionalities such as digital currencies and the dynamism of smart contracts. Yet, with all its promise, the foray of blockchain into domains such as commercial banking is still in its infancy, grappling with hurdles related to regulatory acceptance and broad market recognition. At the heart of blockchain lie its blocks: repositories of transactional data linked in a sequential chain. This design ensures paramount data integrity, upheld by stringent cryptographic principles. As industries gradually awaken to its potential, blockchain's evolutionary journey is bound to unfold further nuances, driving transformation in ways yet to be fully realized.

Research and Design of P2P-SIP System Network Structure Based on JXTA

The network structure of P2P-SIP system based on JXTA is one of the core technologies in industrial intelligent Internet.JXTA is an open peer-to-peer platform, which provides basic application services for building P2P network. This paper chooses JXTA development platform to build P2P network, and then constructs SIP soft terminal on it. Firstly, it introduces the background knowledge, related research, P2P network technology, JXTA technology and SIP protocol. Then, the feasibility of p2p sip system is analyzed, including the combination of P2P and sip, network structure and framework structure. Then the routing mechanism of JXTA is deeply studied, including distributed index of shared resources, limited range traversal, dynamic view of sink node and loose and consistent distributed hash table (DHT). At the same time, this paper proposes an improvement strategy to overcome the shortcomings of JXTA routing mechanism such as limited range traversal and loose consistent DHT, that is, introducing the chord ring of consistent hash algorithm in the aggregation network layer. Based on the in-depth study of JXTA structured network and SIP protocol, a P2P SIP system is designed and implemented. The experimental results show that the system can maintain normal SIP communication without maintaining the central server.

PELANGGARAN HAK CIPTA DI MEDIA SOSIAL

Social media is a group of Internet-based applications built on the ideology and technology of Web 2.0 and makes communication activities easier and faster. Social media channels would not function without the Internet. However, these facilities cause a massive infringement of copyright on social media platforms. Copyright infringement on social media is primarily about file-sharing activities. These activities that use user-to-friend (P2P) technology have triggered a phenomenon in the Internet world. This P2P network technology enables users to exchange digital files anywhere they like. Indirectly, this technology has brought conflicts on the Internet between copyright owners and users. It is important to note that technology is evolving and does not always conform to the law. Therefore, the disparity between copyright law and technology needs to be bridged. An important issue is whether there are appropriate provisions for copyright infringement on social media. This is because, by law, we need to ensure that we have appropriate provisions regarding copyright infringement issues on social media. This article discusses the provisions of the current Copyright Act 1987 relating to copyright infringement and whether they are appropriate for use on the Internet as on social media sites. This article uses the method of legal research through library research. This article concludes that existing laws are conclusively designed and that the provisions of these provisions cover various types of copyright infringement, including those that occur on social media.

Research on Block Chain Product Evaluation System

Block chain technology has occupied a very important position in today's society. This emerging technology has been successfully explored and developed in many fields and scenarios. However, due to the fact that block chain technology is still in the exploratory stage, there is no rigid specification and index for block chain products, Integrating the research results of block chain technology architecture and security risk assessment, this paper designs a set of evaluation indicators for block chain products. The indicators are divided into six aspects, including P2P network technology evaluation index, distributed ledger technology evaluation index, asymmetric encryption technology evaluation index, smart contract evaluation index, consensus mechanism evaluation index and other security technologies Evaluation indicators, each big evaluation index is subdivided into several more in-depth evaluation indicators, and each of the specific analysis and explanation. Finally, based on the previous analysis and design work, a block chain product evaluation software is developed, which provides users with the function of comprehensive evaluation of block chain products. The design and software implementation of the block chain product evaluation system can effectively improve the efficiency in the development of block chain products and the quality of the products themselves, which is conducive to the further development of the block chain field.

A bipolar system of copyright in the internet environment

In this paper, I am elaborating upon Alexander Peukert's proposal for a bipolar copyright system in the internet environment; said system focuses on securing for the right-holder the freedom to choose among given options, i.e., the author's freedom to choose between exclusive, proprietary exploitation on the basis of DRM or participating in the levy/tax system as regards non-commercial file-sharing. Peukert's proposal considers a spectrum of proposals for future copyright models regarding p2p networks that would replace exclusive rights in the copyrightable subject matter with mandatory remuneration rights. The fundamental notion of these concepts is that efficient control of the use of p2p network technology is not possible without outright banning the technology altogether or without severe drawbacks with regard to monitoring and privacy. To avoid these disadvantages, non-commercial file sharing would be legalised under a limitation of or exception from copyright. Right holders would be compensated by a levy or tax on products and services used for file-sharing. The congeniality of this solution rests upon the fact that it preserves the benefits of p2p network technologies while at the same time guaranteeing author's compensation.

Energy saving in P2P oriented Wireless Sensor Network (WSN) using the approach of various compression techniques

Recent advancements & popularity of peer-to- peer networks draws a lot of attention of networking researchers. Wireless sensor network (WSN) consists of various scattered autonomous sensors to maintain regular supervision on physical or environmental conditions, such as temperature, vibration, audible signals, pressure, movements and to collaboratively pass their data through the network to a main location. So in this paper we have considered energy saving concept of wireless sensor network with respect to P2P network technology. For reducing energy consumption by sensors the use of various compression techniques on data before transmission have discussed in this paper. Different types of compression techniques are there and the best one is dependent on the network technology and data characteristics. For choosing the best one of them we have discussed Adaptive Compression Environment technology (ACE) in this paper. Keywords: Peer-To-Peer (P2P) Networks, Wireless Sensor Networks (WSN), Data Compression Techniques, Distributed Networks, Adaptive Compression Environment (ACE)

Privacy-conscious P2P data sharing scheme with bogus profile distribution

With the increasing use of P2P (peer-to-peer) network technology in everyday services, the issue of privacy protection has gained considerable importance. This paper describes a method to realize an anonymity-conscious P2P data sharing network. The proposed network allows users to extract data possessed by other users who have similar profiles, thereby providing them with a collaborative filtering-based data recommendation. In the proposed P2P network protocol, bogus user profiles are distributed intentionally throughout the network to protect users' anonymity without harming the overall effectiveness of the data exchange. We conduct a series of simulations to prove that our proposed method protects the profile's privacy and performs efficient data exchange.

Architecture of home gateway for device collaboration in extended home space

Extended home space refers not only to home appliances but also to logical space, including a wide range of out-home personal devices such as mobile phones, PDAs, laptops, car navigators, and office PCs. Seamless networking and collaboration among these devices is essential to provide users with a ubiquitous home environment in which they can use home services whenever and wherever they want to. In reality, however, there are certain barriers to this, such as the dynamic IP address, NAT, and heterogeneous service protocols. In this paper, we propose a Home Gateway that provides unrestricted collaboration between personal devices in the extended home space by overcoming these barriers with P2P networking technology.

A Trust-Scheme-Based DRM Model for P2P System

With the maturation of P2P technology, there are more and more challenges to the protection of digital rights. DRM for traditional Client/Server model can not satisfy the requirement of digital right protection of P2P network. With practical application of P2P network technology and new generational DRM technology, the article proposes a DRM model for P2P system based on trust degree. The proposed model shares the secret key to the trusty peers and affords necessary security ensure for digital content delivery based on P2P technology. Mathematic analyses and simulations show that, compared to the current DRM model, the proposed model is more robust toleration of transmit and security.

Direct Infringement on Peer-to-Peer Networks

In 2001, the Ninth Circuit affirmed a trial court decision that some 75 million Americans were infringing copyright by exchanging music files in the MP3 format via a peer-to-peer (P2P) network known as Napster. The breathtaking sweep of this holding - that almost one quarter of the population of the United States was engaging in illegal (and likely criminal) activity - was reason enough to give the case a second look. But most of the scholarly attention lavished on the Napster case focused on Napster's secondary liability for providing the technology of infringement. There has been little analysis of the primary infringement committed by Napster's users. Indeed, the alleged primary infringement of P2P users seems to be an example of a phenomenon one sometimes encounters in the common law: A case finds liability, with little or no analysis. A later case also finds liability, with no independent analysis, citing the first case. A third case does the same, citing the first two cases. Before long, the principle of liability is declared to be well-settled, despite an almost complete lack of reasoning supporting the principle. The so-called RAM copy doctrine, discussed below, is a good example of this phenomenon. Direct P2P infringement seems destined to be another: While Napster, the first of the P2P cases, at least briefly discusses the basis for the direct liability of Napster's users, later cases have done little more than mention that P2P users infringe copyright, as if it were self-evident. In this article, I will analyze the activities of P2P users to determine more precisely which, if any, of their actions infringe copyright. I suggest that one reason courts do not delve more deeply into the question of direct infringement is that in fully-litigated cases, the alleged direct infringers are not before the courts; their rights are being adjudicated in absentia. Moreover, the actual defendants in these cases - the alleged secondary infringers - are poor proxies for the users of P2P networks and have no incentive to promote clear judicial analysis, because clear analysis will result in secondary liability. Yet it is important from a policy standpoint to be clear about which activities infringe and which do not. Part II of this Article will describe the process of copyright lawmaking and the recent evolution of copyright law in response to technology. This discussion will include a brief description of conventional and P2P network technology. A copyright analysis of user activities on P2P networks follows in Part III, which argues that the nature of copyright legislation requires courts to be especially careful and precise in determining the contours of infringing noncommercial conduct by members of the public. The analysis in Part III will lead to the conclusion that copying by P2P users does not infringe copyright, but distribution does. In Part IV, I address some strategic considerations affecting copyright enforcement and P2P networks, and I will argue that the rights of consumers to use copyrighted works are gravely threatened by the current of litigation against secondary infringers. Finally, I propose the reinvigoration of Sony as a way to preserve the public benefit of P2P technology.

Brokerless trust and reputation implementation for intelligent community spaces

AbstractAn intelligent community spaces architecture (COMNet), which supports the activation of communities through the application of P2P network technology, is proposed. COMNet can form network communities without requiring a broker. We call this a broker‐less model. In this paper, we propose a distributed trust‐control technology as one of the component groups of COMNet. This technology is important to the formation of reliable network communities. We propose a few trust algorithms and two types of reputation algorithm using information from other entities as elements of distributed trust‐control technology. Copyright © 2004 AEI
