MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611114493 A) filed by Indian Institute Of Technology Delhi on September 24, 2026, for System And Method For Multimodal Physical Unclonable Function Authentication Using Perovskite Nanoparticle Network.
Inventors include Ray, Nirat; Mishra, Partha; and Manna, Aditi.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: Disclosed herein is a multimodal physical unclonable function (PUF) authentication system (100) and method (800) using a perovskite nanoparticle network (106) having an antisolvent-modified interparticle structure (708). The method comprises acquiring an optical response and an electrical response from the perovskite nanoparticle network (106) under corresponding optical and electrical interrogation conditions. The method further comprises generating optical response data and electrical response data based on the acquired responses, identifying one or more optical response regions using the electrical response data, and extracting selected optical response data corresponding to the identified optical response regions. The method further comprises generating an authentication signature using the selected optical response data and the electrical response data and determining authenticity of an article (108) based on the authentication signature. The disclosed system and method may further facilitate multimodal authentication, enhanced resistance to cloning and modeling attacks, generation of high-entropy authentication signatures, and long-term authentication stability.
