A Multilayer Secure Biomedical Data Management System for Remotely Managing a Very Large Number of Diverse Personal Healthcare Devices

الملخص EN

In this paper, a multilayer secure biomedical data management system for managing a very large number of diverse personal health devices is proposed.

The system has the following characteristics: the system supports international standard communication protocols to achieve interoperability.

The system is integrated in the sense that both a PHD communication system and a remote PHD management system work together as a single system.

Finally, the system proposed in this paper provides user/message authentication processes to securely transmit biomedical data measured by PHDs based on the concept of a biomedical signature.

Some experiments, including the stress test, have been conducted to show that the system proposed/constructed in this study performs very well even when a very large number of PHDs are used.

For a stress test, up to 1,200 threads are made to represent the same number of PHD agents.

The loss ratio of the ISO/IEEE 11073 messages in the normal system is as high as 14% when 1,200 PHD agents are connected.

On the other hand, no message loss occurs in the multilayered system proposed in this study, which demonstrates the superiority of the multilayered system to the normal system with regard to heavy traffic.
