Assessing Disclosure Risk for Record Linkage
نویسنده
چکیده
An intruder seeks to match a microdata file to an external file using a record linkage technique. The identification risk is defined as the probability that a match is correct. The nature of this probability and its estimation is explored. Some connections are made to the literature on disclosure risk based on the notion of population uniqueness.

Assessing and Mitigating Disclosure Risk with Multiple Record Linkage
This study examines privacy disclosure risks when multiple records in a dataset are associated with the same individual. Existing data privacy approaches typically assume that each individual in a dataset corresponds to a single record, which tends to underestimate the disclosure risks in the multiple-record problems. We propose a novel privacy approach, which uses a measure called g-balance to...
متن کاملUsing Mahalanobis Distance-Based Record Linkage for Disclosure Risk Assessment
Distance-based record linkage (DBRL) is a common approach to empirically assessing the disclosure risk in SDC-protected microdata. Usually, the Euclidean distance is used. In this paper, we explore the potential advantages of using the Mahalanobis distance for DBRL. We illustrate our point for partially synthetic microdata and show that, in some cases, Mahalanobis DBRL can yield a very high re-...

Disclosure limitation methods for protecting the confidentiality ofrespondents in survey microdata often use perturbative techniques whichintroduce measurement error into the categorical identifying variables. Inaddition, the data itself will often have measurement errors commonly arisingfrom survey processes. There is a need for valid and practical ways to assess theprotect...
متن کاملDisclosure risk assessment in statistical microdata protection via advanced record linkage
The performance of Statistical Disclosure Control (SDC) methods for microdata (also called masking methods) is measured in terms of the utility and the disclosure risk associated to the protected microdata set. Empirical disclosure risk assessment based on record linkage stands out as a realistic and practical disclosure risk assessment methodology which is applicable to every conceivable maski...
متن کاملEvaluation of the disclosure risk of masking methods dealing with textual attributes
Record linkage methods evaluate the disclosure risk of revealing confidential information in anonymized datasets that are publicly distributed. Concretely, they measure the capacity of an intruder to link records in the original dataset with those in the masked one. In the past, masking and record linkage methods have been developed focused on numerical or ordinal data. Recently, motivated by t...
