DESCRIPTION:Record linkage allows data from different sources to be integr
 ated to facilitate data mining tasks. However\, in many cases\, records ha
 ve to be linked by personally identifiable information. To prevent privacy
  breaches\, ideally records should be linked in a private way such that no
  information other than the matching result is leaked in the process.&nbsp
 \;One approach for Private Record Linkage (PRL) is by using cryptographic 
 protocols. In this talk\, I will introduce Private Set Intersection (PSI)\
 , which is a type of cryptographic protocol that enables two parties to ob
 tain the intersection of their private sets. It is almost trivial to build
  an exact PRL protocol from a PSI protocol. With more efforts\, it is also
  possible to build an approximate PRL protocol from PSI that allows linkin
 g records based on certain similarity metrics. In this talk\, I will prese
 nt efficient PSI protocols\, and how to obtain PRL protocols that are prac
 tically efficient and effective. &nbsp\; &nbsp\;&nbsp\;<br>
