一种有效的Web查询日志聚类分析方法

An Effective Clustering Approach to Web Query Log Anonymization

Amin Milani Fard, Ke Wang

摘要:

Web查询日志数据包含对研究有用的信息;然而,此类数据的发布可以重新识别发出查询的搜索引擎用户。这些隐私问题远远超出了删除姓名和地址等明确识别信息的范围,因为非识别个人数据可以与公开信息相结合,以确定个人。在这项工作中,我们的Web查询日志建模为非结构化的交易数据,并提出了一种新的交易匿名技术的基础上聚类和泛化技术,以实现k-匿名隐私。我们对AOL查询日志数据进行了广泛的实验。我们的研究结果表明,这种方法导致更高的数据效用相比,最先进的交易匿名化方法。

英文摘要:

Web query log data contain information useful to research; however, release of such data can re-identify the search engine users issuing the queries. These privacy concerns go far beyond removing explicitly identifying information such as name and address, since non-identifying personal data can be combined with publicly available information to pinpoint to an individual. In this work we model web query logs as unstructured transaction data and present a novel transaction anonymization technique based on clustering and generalization techniques to achieve the k-anonymity privacy. We conduct extensive experiments on the AOL query log data. Our results show that this method results in a higher data utility compared to the state of-the-art transaction anonymization methods.
