12/20/2015 · Probabilistic record linkage . Despite the name, the first stage of probabilistic record linkage is not a statistical issue. If you are attempting to link the two files illustrated in Figure 1, you are required to create a file which compares all records in the master file with those in the file of interest.

11/7/2013 · In this paper, we provide a tutorial on record linkage and a systematic review of the literature on privacy preserving record linkage (PPRL) for biomedical research. We also synthesize the literature to propose a new framework, privacy preserving interactive record linkage (PPIRL), for data integration with tractable privacy and utility properties.

Record Linkage Types: Deterministic or rules-based record linkage generates links based on the number of individual identifiers that match among the available data sets. Two records are said to match via a deterministic record linkage procedure if all or some identifiers (above a certain threshold) are identical.

This study has shown the feasibility of privacy preserving record linkage of large scale datasets. By using the bloom filter method to encrypt and compare individual fields, along with a probabilistic linkage framework, large scale privacy preserving linkage can occur at no cost to linkage quality.

Record linkage is a process of pairing records from two files and trying to select the pairs that belong to the same entity. The basic framework uses a match weight to measure the likelihood of a correct match and a decision rule to assign record pairs as "true" or "false" match pairs.

12/20/2015 · Deterministic record linkage is commonly performed in many research studies and assumes there is a known key which links two files together—the MF and FOI, as defined above. The results from a deterministic record linkage procedure will result in two mutually exclusive categories of ‘matched’ and ‘unmatched’ records.
