MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641063430 A) filed by M. Kumarasamy College Of Engineering, Karur, Tamil Nadu, on May 19, for 'a system for automated detection and secure redaction of sensitive information in digital documents.'
Inventor(s) include Dr. L. Muthulakshmi; Nithiyanantham T; Sukant R; Subburaman V; and Mukesh M.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses an automated system designed to protect personal and confidential information in digital documents. The invention combines machine learning, Retrieval-Augmented Generation (RAG), and Optical Character Recognition (OCR) to detect, classify, and hide sensitive data, including names, addresses, identification numbers, date of birth, financial information, and contact details. The system is capable of processing multiple document formats, such as PDF, DOCX, JPG, and PNG, including scanned or image-based documents. The workflow involves extracting text from documents using OCR, preprocessing to enhance quality and normalize layout, detecting sensitive fields using RAG and machine learning models, classifying the detected fields into categories such as personal, demographic, financial, and contact information, and providing a user-interactive interface to review and apply redaction. The invention not only enhances operational efficiency but also establishes a framework for scalable privacy automation. The BlurD's adaptability ensures it can serve as a foundational tool for digital ecosystems emphasizing confidentiality, integrity, and accountability in data handling."
