摘要
提出了一种基于信息混淆的社会网络隐私保护机制,其原理在于对整个社会网络里的隐私信息进行混淆,而非加密,使得需要保护的隐私信息以环形结构在社会网络里扩散开来。该机制以非集中化的方式工作,由用户之间的相互协作来保护用户的隐私信息。以"人人网"为平台,利用Firefox的扩展开发功能实现了该隐私保护的核心机制,证明了其可行性与可用性。该机制能够保证多方面的利益:要求隐私保护的主体用户、广告商、经过授权的用户及第三方应用。
A privacy protection mechanism based on information mixing is proposed. The principle of privacy-buddy mechanism ismixing private information in the to be spread in a ring-like way entiresocialnetwork, butnottheencryptionofprivateintormation, whichallowsprlvatelntormation The mechanism works in a decentralized way and does not need centralized trusted third-party server. Users protect their privacy through collaboration. A version of PB on renren.com as a Firefox extension is implemented. This version provides evidence for feasibility and availability of the core mechanism. Our mechanism can ensure the interests of multiple aspects： users demanding privacy protection, advertisers and authorized users or third-party applications requiring access to private information.
