MUMBAI, India, Nov. 21 -- Intellectual Property India has published a patent application (202541056398 A) filed by Dr. Sudha Joseph; Kottaram Viswanathan Ramesh; Dr. Thirukkumaran R; and Dr. Antony Louis Piriyakumar Douglas, Bengaluru, Karnataka, on June 11, for 'voc-integrated noncontact non-invasive biometric authentication system using gas and sweat analysis and method thereof.'
Inventor(s) include Dr. Sudha Joseph; Kottaram Viswanathan Ramesh; Dr. Thirukkumaran R; and Dr. Antony Louis Piriyakumar Douglas.
The application for the patent was published on Nov. 21, under issue no. 47/2025.
According to the abstract released by the Intellectual Property India: "A biometric system and method for authenticating a human being using volatile organic compound (VOC) is disclosed. The system comprises at least one VOC sensor to detect corresponding VOCs emitted bya human. The sensor data is communicated to a processing unit, where it is analysed preferably using machine learning modelsagainst a dataset stored in a storage unit. The result of the authentication is displayed on a display unit. The system may also incorporate additional biometric modalities such as fingerprint recognition. The method includes measuring the concentration of VOCs and/or gases, transmitting the data to a processing unit, analyzing the data using learned models, and authenticating and displaying the result. This multimodal biometric system enhances the accuracy and reliability of human authentication based on chemical signatures. It also detects the liveness of humans with measured values of VOCs."
