Blur Before You Publish: Image Redaction Tools
Episode 4449
Published 2 weeks, 5 days ago
Description
Taking photos for a blog post seems harmless until a QR code in the background links to your internal dashboard. While text redaction is practically solved, images remain a challenge. This episode explores the open-source tools and cloud APIs available for automated image obfuscation — from pyzbar and OpenCV for QR detection to OCR pipelines that find PII in photos. We break down the two-stage detection problem and what actually works today.
