DESCRIPTION:Record linkage to integrate uncoordinated databases is critica
 l to population  informatics research. Balancing privacy protection agains
 t the need for high  quality record linkage requires a human-machine hybri
 d system to manage  uncertainty in the ever changing streams of chaotic bi
 g data safely. We review  the literature in record linkage and privacy. In
  the computer science  literature\, private record linkage\, which investi
 gates how to apply a known  linkage function safely is the most published 
 area. However\, in practice\, the  linkage function is rarely known. Thus\
 , there are many data linkage centers  whose main role is to be the truste
 d third party to determine the linkage  function manually and link data fo
 r research via a master population list for a  designated region. Most rec
 ently\, a more flexible computerized third party  linkage platform\, Secur
 e Decoupled Linkage (SDLink)\, has been proposed based on  (1) decoupling 
 data via encryption\, (3) obfuscation via chaffing (addi ng fake  data) an
 d universe manipulation\, and (3) minimum incremental information  disclos
 ure via recoding. Based on this findings\, we formalize a new framework  f
 or privacy preserving interactive record linkage (PPIRL) with tractable pr
 ivacy  and utility properties. Human based third-party linkage centers for
  privacy  preserving record linkage are the accepted norm internationally.
  We find that a  computer based third-party platform that can precisely co
 ntrol the information  disclosed at the micro level and allow frequent hum
 an interaction during the  linkage process\, is an effective human-machine
  hybrid system that significantly  improves on the linkage center model bo
 th in terms of privacy and utility. <br> <br>Related Links <ul> <li><a tar
