This paper presents bilateral key handshaking method between patient and medical people. It builds using pseudo inverse matrix investigates to attack an adaptation layer of IP-USNs (IP-base ubiquitous sensor network). It is a healthcare facilities technique among medical people and patient to convey biomedical data accurately and securely. However, the implementation presents a secure global healthcare monitoring system can be utilized and can consequently improve service providers' workflow. Their lots of system already implemented for security such as large databases, complex expert and knowledge-based systems. But in healthcare monitoring case, patient privacy is a very sensitive and important issue. However, anywhere at any time connectivity between patient and service provider technique is designed.
