MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202611089928 A) filed by Dr. Vaibhav Saran; and Ms. Arpita Sharma on July 23, 2026, for A Physics-Informed Multimodal Forensic Document Analysis System With Cross-Layer Interaction Index For Integrated Ink, Paper, Printer And Signature Authentication.
Inventors include Dr. Vaibhav Saran; Ms. Arpita Sharma; Ms. Jyoti Tanwar; Ms. Hephzibah Rebecca Babu; Ms. Afreen Tarannum; Mr. Manik Chand; Mr. Devesh Tiwari; and Ms. Palack Asati.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: The present invention discloses a physics-informed multimodal forensic document analysis system integrating synchronized multispectral imaging, 3D surface profilometry, fibre microscopy, and toner deposition depth analysis. The system introduces a novel Cross-Layer Forensic Interaction Index (CFII) quantifying material interactions between ink, toner, paper substrate and signature pressure. A physics-informed neural network generates an integrated authenticity score suitable for forensic reporting.
