In secure remote user authentication, the remote server verifies the user’s identity via a potentially unsafe channel of communication. Several types of remote user authentication techniques have been developed ever since, each with its own set of benefits and drawbacks. Real-time applications, such as E-health, telemedicine, the (IoT), the cloud, and multi-server applications, are profoundly affected by remote user authentication systems, including their strengths and weaknesses. Effective control in e-health schemes may be achieved by the provision of several channels for data transfer. When more adaptable forms of communication are established, however, this new method also raises questions of safety and privacy. It’s a fascinating challenge to find a way to authenticate individuals in e-health systems while also guaranteeing their data’s safety. This study presents a data-driven trust mechanism based on blockchain as a decentralised and energy-efficient tactic to detect internal assaults in the Internet of Things. Second, a safe RSA method variant is used to encrypt the data before it is sent. These improvements have a substantial impact on the longevity of the network. Medical data has strict security requirements, and our method meets those needs. Results from the assessment and security analysis demonstrate that the presentation of the proposed technique is greater to that of previously used approaches. The system’s efficiency has been shown experimentally.
