Privacy-Preserving Record Linkage and Privacy-Preserving Blocking for Large Files with Cryptographic Keys using Multibit Trees
Increasingly, administrative data is being used for statistical purposes, for example registry based census taking. In practice, this usually requires linking separate files containing information on the same unit, without revealing the identity of the unit. If the linkage has to be done without a unique identification number, it is necessary to compare keys which are derived from unit identifi...
متن کاملParallel Privacy-Preserving Record Linkage using LSH-based blocking
Privacy-preserving record linkage (PPRL) aims at integrating person-related data without revealing sensitive information. For this purpose, PPRL schemes typically use encoded attribute values and a trusted party for conducting the linkage. To achieve high scalability of PPRL to large datasets with millions of records, we propose parallel PPRL (P3RL) approaches that build on current distributed ...
متن کاملEvaluating privacy-preserving record linkage using cryptographic long-term keys and multibit trees on large medical datasets
BACKGROUND Integrating medical data using databases from different sources by record linkage is a powerful technique increasingly used in medical research. Under many jurisdictions, unique personal identifiers needed for linking the records are unavailable. Since sensitive attributes, such as names, have to be used instead, privacy regulations usually demand encrypting these identifiers. The co...
متن کاملPrivacy-preserving record linkage using Bloom filters
BACKGROUND Combining multiple databases with disjunctive or additional information on the same person is occurring increasingly throughout research. If unique identification numbers for these individuals are not available, probabilistic record linkage is used for the identification of matching record pairs. In many applications, identifiers have to be encrypted due to privacy concerns. METHOD...
متن کاملPrivacy preserving record linkage using homomorphic encryption
The bloom filter method for privacy preserving record linkage [24] has been shown to be both efficient, and provide equivalent linkage quality to that achievable with unencoded identifiers [23]. However in some situations, the bloom filter method may be vulnerable to frequency attacks, which could potentially leak identifying information [18]. In this paper we extend the bloom filter protocol t...
