MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611022880 A) filed by Swami Vivekanand Subharti University, Meerut, Uttar Pradesh, on Feb. 26, for 'a self-calibrating hardware-rooted system and method for generating cryptographic keys from live multi-physiological signals without biometric or key storage.'
Inventor(s) include Dr. Vaibhav Goel Bhartiya; Dr. Amit Kishore; and Dr. Amit Goel.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a self-calibrating, hardware-rooted cryptographic key generation system and method that derive cryptographic entropy from live, cross-correlated multi-physiological bio-signals in combination with intrinsic device-specific analog imperfections. The system acquires real-time physiological signals from a user and processes the signals entirely within trusted hardware circuitry to generate cryptographic keys on demand. A hardware-assisted entropy extraction and fusion module combine physiological entropy with analog hardware variability, while a self-calibration mechanism dynamically adapts to physiological drift, motion artifacts, and environmental variations to ensure reliable key regeneration. The cryptographic keys are generated within volatile hardware logic and are transiently utilized for secure authentication, encryption, or access-control operations, without storing biometric data, physiological templates, or cryptographic keys."
