Performing randomized response (RR) over multi-dimensional data is subject to
the curse of dimensionality. As the number of attributes increases, the
exponential growth in the number of attribute-value combinations greatly
impacts the computational cost and the accuracy of the RR estimates. In this
paper, we propose a new multi-dimensional RR scheme that randomizes all
attributes independently, and then aggregates these randomization matrices into
a single aggregated matrix. The multi-dimensional joint probability
distributions are then estimated. The inverse matrix of the …
