Concentrated Geo-Privacy. (arXiv:2305.19756v1 [cs.CR])

This paper proposes concentrated geo-privacy (CGP), a privacy notion that can
be considered as the counterpart of concentrated differential privacy (CDP) for
geometric data. Compared with the previous notion of geo-privacy [ABCP13,
CABP13], which is the counterpart of standard differential privacy, CGP offers
many benefits including simplicity of the mechanism, lower noise scale in high
dimensions, and better composability known as advanced composition. The last
one is the most important, as it allows us to design complex mechanisms using
smaller …
