Abstract

A computer-implemented method is provided for use in anonymizing data, the data having a plurality of data attributes, or fields. The method is performed by a computer system 501 configured to provide anonymized data to a plurality of different analysis functions 515, 517, 519, 521 for analyzing the data, the data being anonymized by applying one or more of a plurality of predetermined anonymization protocols, each protocol having an anonymization protocol parameter that can be specified in order to determine the degree of anonymization applied to the data. The method comprises determining, for each analysis function: privacy settings, each comprising a unique combination of anonymization protocol applied to the data, anonymization protocol parameter value and data attribute; a privacy score P for each of the determined unique combinations of anonymization protocol applied to the data, anonymization protocol parameter value and data attribute; and a data utility score U for each of the determined unique combinations of anonymization protocol applied to the data, anonymization protocol parameter value and data attribute. The method further comprises processing the results, for each analysis function, by: ranking the unique combinations of anonymization protocol, anonymization protocol parameter and data attribute based on the privacy score and/or data utility score; and storing the ranked results for subsequent selection and use by the computer system to process an anonymized set of data, anonymized according to an identified anonymization protocol, according to the analysis function. A corresponding computer system and computer program are also provided.
