Method and apparatus for variable privacy preservation in data mining

摘要

Improved privacy preservation techniques are disclosed for use in accordance with data mining. By way of example, a technique for preserving privacy of data records for use in a data mining application comprises the following steps/operations. Different privacy levels are assigned to the data records. Condensed groups are constructed from the data records based on the privacy levels, wherein summary statistics are maintained for each condensed group. Pseudo-data is generated from the summary statistics, wherein the pseudo-data is available for use in the data mining application. Principles of the invention are capable of handling both static and dynamic data sets

1. A method for preserving privacy of data records for use in a data mining application, comprising the steps of:
assigning different privacy levels to the data records; constructing condensed groups of data records from the data records based on the privacy levels, wherein at least one condensed group of data records comprises a first data record having a first privacy level, which is condensed with a second data record having a second privacy level different than the first privacy level maintaining summary statistics for each condensed group of data records; and generating pseudo-data from the summary statistics, wherein the pseudo-data is available for use in the data mining application, wherein the assigning, constructing, maintaining and generating steps are performed by a data processing system.
