Abstract: A set of data is received for a data analysis. The set of data includes personal identifiable information. The set of data is anonymized to protect the privacy information. Risk rates and utility rates are determined for a number of combinations of anonymization techniques defined correspondingly for data fields from the set of data. A risk rate is related to a privacy protection failure when defining first anonymized data through applying a combination of anonymization techniques for the data fields. A utility rate is related to accuracy of the data analysis when applied over the anonymized data. Based on evaluation of the risk rates and the utility rates, one or more anonymization techniques from the number of anonymization techniques are determined. The set of data is anonymized according to a determined anonymization techniques and/or a combination thereof.
