PrivacyBridge – local-first, reversible anonymization for Italian docs (github.com)

PrivacyBridge has been introduced as a local-first application designed for reversible anonymization of sensitive Italian documents. This innovative tool replaces personal identifiers—such as names, IBANs, and tax codes—with placeholders, allowing users to process documents with AI assistants like ChatGPT without compromising their privacy. Notably, the original data can be restored byte for byte on the user's device, as no information leaves the computer during this process. This development is significant for the AI/ML community as it showcases a practical solution to privacy concerns associated with handling personal data in AI workflows. PrivacyBridge operates entirely offline after the initial setup, using Python and local neural models, ensuring security and compliance with data protection regulations. It supports various document formats and incorporates features like native OCR, allowing users to anonymize scanned documents effectively. Furthermore, it includes built-in verifiability measures and guarantees that prevent data leaks, making it a pioneering tool in the field of privacy-preserving AI applications.
