摘要

摘要

En 中文
为防止大数据的收集和发布过程中发生个人信息泄露,保护隐私同时保留数据用途的匿名化技术至关重要。特别是,m-invariance为连续发布并不断更新的动态数据集提供了隐私保护。然而,以往研究面临执行时间随数据集总规模增加而增长的问题,且未对大规模数据集进行评估。在我们对先前研究的复现中,对100万条动态记录进行匿名化平均需要约7小时的执行时间。为解决此问题,我们提出了一种新的m-invariance算法,专注于记录的插入和删除操作,其与数据集总规模无关。我们在CPU和FPGA平台上实现了该算法,在两个平台上对包含100万条记录的数据集进行5000次更新时,执行时间均低于5秒。CPU实现和FPGA实现的每条更新记录吞吐量分别为57 ms/record和2 ms/record。此外,通过FPGA上的缓冲资源优化,我们展示了匿名化超过100万条记录的大规模动态数据集的能力。总之,本研究实现了对100万条动态记录的m-invariance匿名化,支持1 s/record的更新速率。(c) 2025 The Author(s).
