IOT BASED SECURE HEALTH CARE SYSTEM USING BSN

Abstract

Body Sensor Network (BSN) which can be used mainly for Physiological monitoring (i.e., Blood Oxygenation, Pulse Rate, etc..) IoT based Body Sensor network should be implemented in order to improve security. It is mostly useful for the physicians and the patients for real time monitoring, patient information management and health care management. The security requirements can be satisfied using Attribute Based Encryption (ABE) algorithm. It is an type of public-key encryption in which the secret key of a user and the cipher text are dependent upon attributes. Here the patient id and name is used for encryption. It should be noted that if the BP rate of a person is less than or equal to 120, it is considered to be normal and the server does not perform any action. When the BP of the person reaches say 130, the LPU will provide a gentle alert to the person through the LPU devices like Phone, tablet, etc.. (e.g. beep tone) to the family members of the person. If the BP rate becomes greater than 145 and there is no one attending the call in family, then the server will contact the local physician. Furthermore, if the BP rate of the person cross 160 and still there is no response from the family member or the local physician then the BSN-Care server will inform an emergency unit of a healthcare center and securely provides the location of the person. Key Authority is needed for this to generate key for security purposes. Thus we propose a secure IOT based modern healthcare system using the BSN Care which can efficiently improve the security.
