信息共享是群体信息管理的核心,而P2P技术的一个重要应用是信息共享。因此可以将P2P技术与群体信息管理相结合,探讨基于P2P技术的群体环境下成员如何进行信息共享。首先介绍群体信息管理、信息共享、P2P等相关概念,然后调查分析P2P在群体信息管理中的共享优势,并结合Napster、六维空间等相关实例进行介绍。其次,探讨了3种基于P2P技术的群体信息共享模型,包括集中式、分散式和混合式。最后对基于P2P技术下群体信息管理中信息共享的隐私问题进行总结,并提出相应对策。
Information sharing is the core of group information management, and P2P technology is an important application of information sharing. So we can combine P2P technology and group information management to discuss how to share information among members based on P2P technology in group environment. Firstly, the concepts of group information management, information sharing, P2P and so on are introduced. Then, the sharing advantages of P2P in group information management are investigated and analyzed. Relevant examples such as Napster and six-dimensional space are introduced. Secondly, three models of group information sharing based on P2P technology are discussed, including centralized, decentralized and hybrid. Finally, the privacy of information sharing in group information management based on P2P technology is summarized and corresponding countermeasures are proposed.
