Hiding feature information through encryption prevents the server from performing effective scoring and result comparison. On the other hand, unencrypted feature values can lend themselves to privacy attacks. Searchable encryption schemes allow users to search over encrypted data through keywords, but do not support ranking. This talk will present our recent efforts to make private search practical for large datasets with linear and nonlinear ranking methods.</span><span style='font-size:10.5pt;line-height:150%;font-family:等线;color:black'><o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'> </span><span lang=ZH-CN style='color:black'>杨涛，</span><span style='color:black'>1984 <span lang=ZH-CN>年本科毕业于浙江大学计算机系，</span>1993 <span lang=ZH-CN>年在</span> Rutgers <span lang=ZH-CN>大学获得博士</span></span><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'><o:p></o:p></span></p></div><p class=MsoNormal><span class=fontstyle0><span lang=ZH-CN style='color:black'>学位，搜索引擎和高性能计算领域著名学者，目前是加州大学圣芭芭拉分校计算</span></span><span style='color:black'><br><span class=fontstyle0><span lang=ZH-CN>机科学教授，曾任</span> ask.com <span lang=ZH-CN>首席科学家、高级副总裁和搜索部门的工程副总裁，</span></span><br><span class=fontstyle0><span lang=ZH-CN>参与过微软</span> Bing <span lang=ZH-CN>搜索技术的研究和设计，担任过</span> WWW, KDD, WSDM, ECIR, EMNLP,</span><br><span class=fontstyle0>SC, IPDPS, PPoPP, SPAA, and INFOCOM <span lang=ZH-CN>等会议的程序委员会委员。</span></span></span><span lang=ZH-CN style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'> </span><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'><br style='orphans: 2;text-align:-webkit-auto;widows: 2'><br><o:p></o:p></span></p><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'><o:p> </o:p></span></p></div><div><div><p class=MsoNormal><span lang=ZH-CN style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'>谢谢。</span><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'><o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=ZH-CN style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'>黄林鹏</span><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'><o:p></o:p></span></p></div></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'><o:p> </o:p></span></p></div><div class=MsoNormal><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'><hr size=1 width=263 style='width:157.5pt' noshade style='color:#B5C4DF' align=left></span></div><div><p class=MsoNormal><span style='font-size:10.5pt;font-family:"微软雅黑","sans-serif";color:black'>CS<o:p></o:p></span></p></div></div></body></html>
