Indicative relative disclosure risk model.

Data	Implication	Indicative level
Macro CDRa data alone	Highly unlikely to present a significant risk to individual or group identity disclosure	Low
Small-cell CDR data alone	Unlikely to present a significant risk to individual or group identity disclosure	Low-moderate
Macro CDR data with publicly available datasets	Unlikely to present a significant risk to individual or group identity disclosure	Low-moderate
Small-cell CDR data with publicly available datasets	May present a significant risk to individual or group identity disclosure	Moderate
Macro CDR data with restricted datasets	Likely to present a significant risk to individual or group identity disclosure	Moderate-high
Small-cell CDR data with restricted datasets	Highly likely to present a significant risk to individual or group identity disclosure	High
