Improved techniques for privacy preserving data mining of multidimensional
data records are disclosed. For example, a technique for generating at
least one output data set from at least one input data set for use in
association with a data mining process comprises the following
steps/operations. At least one relevant attribute of the at least one
input data set is selected through determination of at least one
relevance coefficient. The at least one output data set is generated from
the at least one input data set, wherein the at least one output data set
comprises the at least one relevant attribute of the at least one input
data set, as determined by use of the at least one relevance coefficient.
