We present a novel privacy protection method for spatial density maps based on wavelet MRA analysis. sdcSpatial is an R package designed to create spatial density maps, while protecting the privacy of the obervations involved. It contains several protection methods, which work well, but may create a suboptimal density map: the spatial resolutions of urban and rural areas often are very different. Wavelet Secure Maps are a novel method that use multi-resolution analysis to derive a spatial density map that adapts to the local spatial resolution. The presentation will introduce the method and its application using the upcoming update for sdcSpatial.
