Build a serverless PII redaction pipeline with Amazon Bedrock Data Automation

AWS Machine Learning · September 16, 2026

This week, a new approach emerges for organizations grappling with the pervasive challenge of safeguarding sensitive personal data embedded within unstructured documents. The AWS Machine Learning team demonstrates a serverless pipeline that fully automates the detection and redaction of Personally Identifiable Information (PII) from scanned documents at scale, leveraging Amazon Bedrock Data Automation. This system utilizes a custom blueprint for precise field-level redaction and incorporates a token matching quality check to enhance accuracy, even on degraded or handwritten materials, all orchestrated via AWS Step Functions and Lambda. This innovation directly impacts anyone handling large volumes of varied documentation containing personal data, from legal forms to customer records, by significantly reducing manual effort and compliance risk. Consider a mid-sized healthcare provider in Phoenix, Arizona, managing patient intake forms; they could automate the secure processing of thousands of documents daily, ensuring HIPAA compliance without expanding administrative staff. A startup in Boise, Idaho, building a legal tech platform could offer a new service, automatically redacting client sensitive information from discovery documents before sharing, increasing trust and efficiency. For an internal IT team at a manufacturing company in Detroit, Michigan, needing to archive decades of HR records, this provides a robust, scalable solution to anonymize historical data before migration to cloud storage, minimizing data breach risks and adhering to data retention policies. Such a system offers tangible benefits, freeing up valuable human capital from tedious, error-prone tasks and enabling organizations to process sensitive information more rapidly and securely. Instead of dedicating hours to manual review, staff can focus on higher-value activities. The ability to handle degraded or handwritten documents further broadens applicability, addressing a common pain point where traditional OCR often falters, thus improving the overall data protection posture. To explore this, identify a small, non-critical internal document workflow that involves scanned or image-based files containing sensitive information. Set up a basic proof of concept using the described Bedrock Data Automation principles to detect and redact a specific type of PII, such as names or addresses. Observe the precision and recall, especially on any older or lower-quality documents you might include.
