Abstract: This paper presents a secure IoT-based health monitoring system that shortens the distance between a patient and the relevant medical organization. Vital signals captured from sensors are processed and encrypted using AES (Advanced Encryption Standard) algorithm. A Node MCU microcontroller is utilized to carry out the processing and encryption functions, and for providing connectivity over WiFi. In addition, a medical specialist can visualize the private health data only after providing credentials. Moreover, the proposed system provides an alert by sending an email to some patient relatives or coordinating specialist if vital signs are outside the normal rates. The proposed system provides privacy, security, and real-time connectivity for private health data records.

Keywords Secure: Health Monitoring, Internet-of-Things (IoT), AES Encryption
