Abstract
A computer-implemented system and method for anonymizing encrypted data is provided. At least one attribute is identified within a dataset for anonymization and is associated with a plurality of data values. Each data value is encrypted for each identified attribute while maintaining an order of the encrypted data values. The encrypted values are ordered and the ordered encrypted data values are segmented into two or more classes based on the ordering of the encrypted data values. A range of the encrypted data values within each of the segmented classes is identified and the range of one of the classes is assigned to each encrypted data value within that class as anonymized data.
