MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202514120425 A) filed by Turant Inc. on December 02, 2025, for Method And System For Continuous Authentication Of Participants In Communication Sessions.
Inventors include Anurag Goel; and Sairam Sankaranarayanan.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: A computer-implemented method provides continuous authentication for a participant in a communication session. The method involves accessing a reference biometric record comprising original voice recordings of the participant and capturing a live voice sample from the participant during the session. The live voice sample is subjected to a parallel analysis, which includes a biometric comparison process to generate an authentication score and a voice liveness detection process. A potential unauthorized access event is determined based on the authentication score in comparison to an authentication threshold and a result of the voice liveness detection. Responsive to determining the potential unauthorized access event, a challenge verification procedure is automatically executed. This procedure includes transmitting a prompt for a challenge-response task, receiving a challenge voice sample, and authenticating the challenge voice sample to generate a challenge result. An authentication status of the participant is then modified based on the challenge result. FIG. 10
