Telemedicine is one of the most rapidly de-veloping areas of health care in recent years. Telemedicine Information Systems (TMIS) enable physicians to pro-vide remote care over the Internet to registered patients anywhere. In this work, we propose an efficient anony-mous authentication scheme between patients and med-ical servers. We combine blockchain technology with biometric technology to form a shared session secret key to protect the privacy of patients through mutual au-thentication between patients and servers. Comprehen-sive comparative measurement shows that our proposed scheme achieves a better experimental performance in both computation and communication efficiencies.
