【摘要】：作为现实中倍受欢迎的网络应用之一,标签系统很容易成为恶意攻击者的目标.在标签系统中,恶意用户常出于特殊目的对系统中的资源标注与其内容不相关的垃圾标签,从而误导普通用户对这些资源的查找和分享.已有工作表明,垃圾标签的抵御效果会直接影响到标签系统的服务质量.基于此背景,通过调研归纳已有文献,从垃圾标签攻击的形式化描述出发,全面总结并抽象出垃圾标签现有的3类抵御方法:基于检测的方法、基于降级的方法和基于预防的方法.对每一类方法,进一步总结和归纳具体的实现算法,并对算法的执行效率和可用性等优缺点进行分析.通过对垃圾标签现有抵御方法的阐述,旨在帮助读者了解该研究领域的现状,并对新的垃圾标签抵御机制的提出有所启发.
[Abstract]:As one of the most popular network applications in reality, tag system is easy to be the target of malicious attackers. In tag system, malicious users often label the resources in the system for special purposes, which are not related to their content. Thus misleading ordinary users to find and share these resources. The existing work shows that the anti-spam effect will directly affect the quality of service of the label system. Based on this background, the existing literature is summarized through research. Based on the formal description of spam tag attack, three kinds of existing defense methods are summarized and abstracted: based on detection, based on demotion and based on prevention. Further summarizes and summarizes the specific implementation algorithm, and analyzes the advantages and disadvantages of the algorithm, such as the efficiency and usability of the algorithm. Through the exposition of the existing defense methods of garbage tags, the purpose of this paper is to help readers understand the current situation of the research field. It also enlightens the proposal of new anti-spam mechanism.
