| 中文简介: |  在这项工作中，我们研究了针对搜索引擎查询日志发布的隐私保护。特别是，我们引入了一个新的隐私问题，即网站隐私（或企业隐私）。我们定义了可能有兴趣公开网站信息的潜在对手以及在查询日志中发现的漏洞，他们可以从中受益。我们还将详细介绍匿名技术，以保护网站信息，并探索对手可能使用的不同类型的攻击。然后，我们提出一种基于图的启发式方法，以验证我们匿名方法的有效性，并对该方法进行实验评估。我们的实验结果表明，仅删除大约9％的查询和单击的URL总量，就可以针对特定的网站曝光攻击对查询日志进行适当的匿名处理。 |
| 课程简介: | In this work we study privacy preservation for the publi- cation of search engine query logs. In particular, we introduce a new privacy concern, which is that of website privacy (or business privacy). We define the possible adversaries that could be interested in disclosing website information and the vulnerabilities found in the query log, from which they could benefit. We also detail anonymization techniques to protect website information, and explore the different types of attacks that an adversary could use. We then present a graph-based heuristic to validate the effectiveness of our anonymization method, and perform an experimental evaluation of this approach. Our experimental results show that the query log can be appropriately anonymized against a specific attack for website exposure, by only removing approximately 9% of the total volume of queries and clicked URLs. |
