Term	Kind	Topic	What it is
Aggregation Threshold Policy Minimum Cohort Rule, k-Threshold Output Policy	pattern	Data Sharing & Clean Rooms	A rule that only returns results computed over at least a minimum number of subjects, plus limits on overlapping queries, so that shared analytics cannot be resolved back to an individual.
Computation-Only Collaboration	pattern	Data Sharing & Clean Rooms	Two parties analysing their combined data without either receiving the other's records, by permitting only queries whose outputs are aggregate.
Data Clean Room	pattern	Data Sharing & Clean Rooms	A controlled environment where two parties analyse their combined data without either gaining access to the other's raw records.
Differencing Attack Query Differencing, Reconstruction Attack	concept	Data Sharing & Clean Rooms	Inferring an individual's data from the difference between two permitted aggregate results - the reason that returning only aggregates is not by itself a privacy guarantee.
Match Rate Bias Matched-Cohort Bias, Identity Coverage Bias	concept	Data Sharing & Clean Rooms	The systematic skew introduced when only the identifiable subset of each party's population joins, so a shared measurement describes the matched cohort rather than the market it is quoted about.
