Abstract:
1. A system for deidentifying entries in an input data source having field-structured data organized in fields and entries, comprising: a processor; and a deidentification module comprising software code which when executed by the processor causes the procecessor to anonymize entries in a version of the input data source by generalizing at least one entry value of the version of the input data source to yield an output data source having field-structured data organized in fields and entries, wherein the generalization is such that a value of each entry within at least one field of the output data source occurs at least k times, and wherein a value of k is such that entries of the output data source match a specified anonymity requirement, and wherein the processor, when executing the software code of the deidentification module, anonymizes entries in the version of the input data source by at least one of suppressing or replacing entry values in the version of the input data source such that the entries of the output data source match the specified anonymity requirement.
