A Review on Blockchain Technology based Secure Intelligent Wearable Devices for 6G Systems

Nowadays, Intelligent Wearable Devices (IWD) are vital in preparing patients' medical records in healthcare companies. These devices will measure essential parameters such as pulse rate, blood pressure, body weight, etc. Once measurements are over, they will quickly transmit the data to respective test centers. These devices will advise the patients on the next course of action, such as walking, jogging, eating, etc. With this approach, patients must visit the hospital frequently, reducing medical expenses. Moreover, this will improve the health status of patients and increase the life span of human beings. 6G systems and these networks are generally connected with human-centric communication. Blockchain is a technique used to implement a distributed database in which a list of records is maintained in an ordered manner. This paper enunciates the impact of Blockchain-based intelligent wearable devices for 6G systems so that the confidentiality of patient records can be protected and shared on demand.
