A mathematical guarantee that results computed from a dataset reveal almost nothing about any one person in it, achieved by adding calibrated noise.
Differential Privacy (DP) adds calibrated statistical noise during the training or querying of AI models, so that including or excluding any single record has only a small, bounded effect on the output. For Private AI deployments that handle PII or PHI, DP is a safeguard against model inversion and membership inference attacks.
