IoT healthcare devices are being used to share the real time personal data of patients to their doctors. Conventionally, centralized systems are used to store personal data and for encryption decryption, property server performed the duty. But those systems give rise to security and response time issues e.g. data breaching while moving the data between devices and server as there are IoT devices which send their data (blood pressure, heart beat rate etc.) as plain text to server and server have to perform encryption/decryption according to the need. Apart this, server have to response back the requests of different healthcare provider’s devices which may increase the response time. Therefore, security and response time are the main issues to be handled. There is a need of system that makes the secure transmission of sensitive healthcare data. We recommend some suggestions to improve those areas.
