LinkIT: Privacy Preserving Record Linkage and Integration via Transformations

Provided by: Association for Computing Machinery
Topic: Big Data
Format: PDF
The authors propose to demonstrate an open-source tool, LinkIT, for privacy preserving record Linkage and Integration via data Transformations. LinkIT implements novel algorithms that support data transformations for linking sensitive attributes, and is designed to work with their previously developed tool, FRIL (Fine-grained Record Integration and Linkage), to provide a complete record linkage solution. LinkIT can be also used as a stand-alone secure transformation tool to link string records. The system uses a novel embedding technique based on frequent variable length grams mined from original records with differential privacy, and utilizes a personalized threshold for performing linkage in the embedded space.
