SYSTEM AND METHOD FOR SHIFTING DATES IN THE DE-IDENTIFICATION OF DATESETS

摘要

A system and method of performing date shifting with randomized intervals for the de-identification of a dataset from a source database containing information identifiable to individuals is provided.. The de-identified dataset is retrieved comprising a plurality of records from a storage device. A selection of date fields from a user is received, the selection made from a plurality of variables present in the dataset, wherein the date fields are potential identifiers of personal information. A selection of date and interval generalizations from a user is received. The choice of date and interval generalization to use is determined based on meeting an acceptable risk threshold, as part of the de-identification of the dataset.
