【Abstract】Patient data are susceptible and vulnerable when collected through open channels. Since these data are collected through various IoT (Internet of Things) devices, mobile applications, and web-based applications, their security is more important. Many hackers and attackers can be found between the patient, the cloud server, and the data collector. Blockchain is a secure, immutable, and transparent method of collecting and storing data. In this paper, a novel scheme for telehealth data sharing is proposed. In this proposed scheme, we use a property mapping function to map the common properties of participating blockchains. The data-sharing case is decided based on the property mapping score, and a temporary blockchain TempChain is created. Data sharing is done using the safe search data and sharing only the required data with the requester blockchain. This proposed scheme improves the security and privacy of telehealth data sharing. The results of the proposed scheme in different cases show the proposed scheme's efficiency with respect to the available state-of-the-art system. The proposed scheme's security is also examined in this paper.
