An R package for anonymization of spatial point patterns and raster objects.
This package achieves the relatively simple, yet pretty useful task of spatial anonymization. Anonymization is needed in situations where a data owner may not wish to share the actual spatial locations of their data, but allows sharing of the data that does not preclude the data from a spatial analysis procedure.
Anonymization is achieved via 3 modes of spatial shifts:
- Vertical shifts
- Lateral shifts
- Rotational shifts
The tangles package can entangle both non-gridded spatial point patterns and raster objects. It can also entangle data using an a priory entanglement sequence, and can disentangle data back to their original spatial representations. Each entanglement process is given a unique hash key label to guarantee disentanglement is a success in terms of data being transformed back to their original representation.
Installation of tangles can be achieved via Github using the devtools package:
devtools::install_github("brendo1001/tangles")
