Abstract We propose to demonstrate an open-source tool, LinkIT, for privacy preserving record Linkage and Integration via data Transforma-tions. LinkIT implements novel algorithms that support data trans-formations for linking sensitive attributes, and is designed to work with our previously developed tool, FRIL (Fine-grained Record In-tegration and Linkage), to provide a complete record linkage so-lution. LinkIT can be also used as a stand-alone secure transfor-mation tool to link string records. The system uses a novel embed-ding technique based on frequent variable length grams mined from original records with differential privacy, and utilizes a personal-ized threshold for performing linkage in the embedded space. Com-pared to the state-of-the-art secure transformation method [16], LinkIT guarantees stronger privacy with better scalability while achieving comparable utility results.
