• 基于大量有价值的信息存在于社交网络的图数据中,大规模地搜集用户属性和节点之间的关系严重危害用户的数据隐私安全。基于本地化差分隐私技术(LDP),我们提出了新的图数据隐私保护算法。以本地化差分隐私的方式搜集用户的数据和属性,同时优化图数据的结构,在数据的可用性和隐私性两个方面达到平衡。
  • 大数据是数字化、信息化发展到一定阶段的产物。近年来,随着互联网与人类生活高度融合,指数增长、海量聚集的数据逐渐成为价值的源泉。“数据即价值”的时代也随之拉开序幕。然而巨大的效益潜力往往掺杂着隐形的数据问题,数据质量、数据处理和数据安全等问题形式愈发严峻。本项目着力于大数据时代的数据质量管理问题,对开放的自收集数据的质量情况进行识别、度量、预警、运维等一系列活...
