MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202641105577 A) filed by Saveetha Institute Of Medical And Technical Sciences on September 02, 2026, for A Depth-Aware Multi-Spectral Fingerprint Acquisition And Recognition System With Adaptive Noise Suppression.
Inventors include Sumesh Mohan; Dr. V. Sheeja Kumari; and Dr Ramya Mohan.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: This invention discloses a depth-aware multi-spectral fingerprint acquisition and recognition system that enhances biometric accuracy under varying skin conditions. The system utilizes multi-spectral illumination to capture both surface and subsurface fingerprint features. An adaptive ridge-depth estimation module dynamically models ridge depth variations, enabling effective noise suppression. The proposed system improves robustness against noise caused by moisture, pressure variations, sensor artifacts, and environmental interference, thereby ensuring reliable fingerprint authentication.
