About

Integrates Microsoft Presidio into an Alfresco T-Engine to redact PII from PDFs or extract it as metadata.

Two transform modes:

  • application/pdf → application/pdf: produces a redacted PDF with configurable label and score threshold
  • application/pdf → alfresco-metadata-extract: returns structured JSON with entity counts, scores, and values, mappable to Alfresco content model properties (pii:hasPII, pii:entities, pii:countPerson, etc.)

Configurable via pii_engine_config.json:

  • entities: list of PII types (PERSON, PHONE_NUMBER, EMAIL_ADDRESS, CREDIT_CARD, …)
  • scoreThreshold: confidence threshold (0.0–1.0)
  • label: replacement text for redacted content

Deployable as a local T-Engine (Community: localTransform.pdf-pii.url) or async T-Engine (Enterprise: queue pii-engine-queue).
