Blockchain and Smart Contracts to Improve Dental Healthcare for Children in Primary School

Privacy preserving is a matter of great importance in many sensitive fields including financial and healthcare areas. As the blockchain technology has achieved an obvious success in privacy protection at the financial level when the Bitcoin has been introduced in 2008, there are considerable attempts and later on successful projects to introduce the blockchain technology to the healthcare fields, where the patient privacy and access control to the personal information is at high priority. The aim of our paper mainly considers the introduction of the smart contracts that are based on the blockchain technology as a method to preserve the patient privacy and improve the reality of dental healthcare providing services.The main focus will be on the treatment plan of the patient by building a smart contract system between multiple partners. By using “the five types models” our proposed system has been built combining the advantages of blockchain technology and the benefits of smart contracts. The programming language that we have used is Solidity along with proof of authority algorithm on Ethereum blockchain. The proposed smart contract system which is based on blockchain technology can provide the privacy preservation of patient information in addition to the digitalization of healthcare data.
