Abstract: Machine learning models deploy ed in consequential domains can become unfair toward protected subgroups a s the data they receive drifts over time\, yet the protected attributes ne eded to measure fairness directly are often unavailable at runtime due to privacy regulation and operational constraints. This creates a gap: existi ng fairness toolkits require protected labels and perform one-time audits\ , while generic drift detectors monitor continuously but cannot localize w hich subgroup a shift harms. This thesis develops a non-invasive fairness drift monitor that addresses this gap by repurposing Conformance Constrain ts\, a data-profiling primitive\, as a temporal fairness signal. The monit or learns per-subgroup distributional profiles at baseline\, using protect ed attributes only once\, and thereafter tracks violation of those profile s over incoming data batches without any runtime access to protected attri butes. Across three fairness benchmarks\, two classifiers\, and nineteen c ontrolled drift scenarios\, the conformance-constraint violation signals t rack fairness degradation more closely than KS and KL detectors under glob al drift\, and they remain competitive with them under group-targeted drif t. Subgroup localization provides its clearest advantage under global drif t\, where a minority-subgroup signal substantially outperforms both aggreg ate signals and the baselines. The correlations are modest in absolute ter ms\, indicating that the monitor functions as a screening instrument that flags fairness degradation for closer investigation rather than as a preci se estimator. The approach offers privacy-preserving\, subgroup-aware fair ness monitoring suited to regulated deployment settings.
