Towards Secure Healthcare 4.0: Zero-Trust-Based Continuous Authentication Framework Using Biometric Pulse Data

This academic paper proposes a security framework for Healthcare 4.0 (the next generation of connected medical systems) that uses zero-trust architecture (a security model that never automatically trusts anyone or anything, even inside a network) combined with continuous authentication based on biometric pulse data (heartbeat patterns used to verify a person's identity). The research suggests that monitoring a patient's unique pulse signature throughout their interaction with medical systems could provide an additional layer of security to protect sensitive health information.
