MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202621040769 A) filed by Sage University, Indore, Madhya Pradesh, on March 31, for 'apparatus for enhanced biometric attendance authentication.'
Inventor(s) include Ms. Sakshi Agrawal; Dr. Prashant Jain; Dr. Sachin Patel; Prof. Vijay Malviya; Prof. Prajakta Kumbhar; and Himanshu Tiwari.
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 disclosure relates to biometric attendance authentication. The apparatus (102) includes a fingerprint sensor assembly (104) that captures cross-sectional images of finger tissue below the skin surface and measures light absorption signals across at least two wavelengths. A facial verification assembly (106) projects an infrared dot pattern onto a subject's face, captures its reflection, and computes a three-dimensional depth map. A control circuit (108) extracts subsurface anatomical structures including outer and inner skin layer boundaries from the cross-sectional images, computes blood oxygen level, and detects a periodic blood flow signal. The control circuit (108) further verifies facial surface geometry against a stored facial geometry profile and computes a composite liveness score from all extracted biometric parameters. Upon the composite liveness score exceeding a configurable threshold, the apparatus (102) transmits an attendance authentication signal to a remote attendance server, recording an attendance event while effectively preventing spoofing attempts."
