After regulators demand numbers in 2016, a Wells Fargo data program builds a pipeline that detects PII at ingestion using a data scan mechanism, applies scalable type detection (credit card, PAN, DOB, address), and auto-tags assets into a catalog with AI/ML cataloging. Master data management plus lineage links ingestion to consumption, business stewards own access policies, and protection uses tokenization, encryption, masking. Result: faster discovery of usable datasets and auditable controls that reduce risky data swamps.
