Abstract

In an example, an anonymized set of confidential data data values of a first confidential data type is obtained. Then an anonymized set of confidential data data values of a second confidential data type is also obtained. A multiplier following a log-normal distribution is determined for the anonymized set of confidential data data values of the first confidential data type. Then smoothing is performed independently for the anonymized set of confidential data data values of the first confidential data type and the multiplier. Percentiles for the anonymized set of confidential data data values of the second confidential data type are then determined using the smoothed anonymized set of confidential data data values of the first confidential data type and the smoothed multiplier.
