Distance-preserving anonymization of data

摘要

An embodiment includes a system 100 with a processing unit 110 and a communication unit 120, The processing unit 110 is configured: to compute a first reference point of a data point that represents a private data item and has a first distance value to the data point, wherein the first distance value is less than a threshold value, to compute a second reference point of the data point different from the first reference point with a second distance value to the data point, wherein the second distance value is less than the threshold value, and to generate hidden reference points from the reference points. The communication unit 120 is configured to send the hidden reference points and distance values to a system 200.
