MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202641084981 A) filed by Vellore Institute Of Technology, Chennai on July 10, 2026, for System And Method For Anti-Spoof Authentication Using Spatio-Temporal Lip Motion.
Inventors include L. M. Jenila Livingston; Bevan Lege George; Advait Cheruvari Vikas; and Amal Shaji.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: A computer-implemented biometric authentication system 100 can include a camera 104 to capture facial video sequences of a user 102; and a server 202 including a plurality of modules, at least one database 228, one or more processors 204 coupled with a memory 206. The memory 206 stores one or more instructions executable by the one or more processors 204 to generate a randomized challenge passphrases or word sequence 108 for the user 102 to respond; capture real-time sequence of video 106 having facial imagery responses during challenge-response phrase 108 authentication; extract lip region-of-interest from the captured video 106 obtained during challenge-response phrase 108 authentication; process extracted lip region of interest through a spatio-temporal feature encoding module 216; compare extracted spatio-temporal features with matching of template stored in database 228; and grant access if extracted spatio-temporal features match with the template, else deny access.
