In this paper, a blockchain-based healthcare security system as a solution for preventing data forging is proposed. The proposed model for healthcare data security is based on blockchain and its smart contract execution in a secure way. We proposed a system where users can access the open surveys and participate in these surveys. Moreover, their answers cannot be changed by anonymous or 3rd party people with smart contract control. At the same time, to ensure the confidentiality of the patient’s data, we kept the hashed value of the information we collected from the patient’s survey data as evidence and the encrypted version so that data can be used for the evaluation, in the relevant storage units of the generated decentralized application.
