For this example, distance matrix are calculated for all relevant rows then k-nearest Neighbors is used to find the"closest" by default 2 records to the original. A record to replace the original is then built by randomly choosing values from the closest neighbors.To test the anonymized data, a standard machine learning excersize is performed on the anonymized data, the original data and also by applying the anonymized model to the original data. Measures of qualityare captured. Other methods of testing quality could be used. To test whether the data is truly anonymized a test is performed to attempt to trace back from the equivalent anonymized record to the original record. Other approaches for deanonymizing could be used.
