An open-source Chrome Extension that identifies and mask PII in images and PDFs using ONNX-based ML models. With the rise of data leaks and oversharing—whether from individuals on social media or employees sharing company and customer data with public LLMs—sensitive information is often exposed unintentionally. We set out to build a lightweight, privacy-first solution that protects data without relying on external servers. By running compact ML models directly in web browsers, we proved this is possible. Our work is combination of Main Track and Business Productivity Track as both enterprises and individuals can use it to improve their security. PII 360 is an open-source Chrome extension that detects and masks multilingual Personally Identifiable Information (PII) in images, text, and PDFs. It uses ONNX-based machine learning models to run fully on the client’s device, ensuring accuracy, speed, and privacy.
